I) INTRODUCTION
Thank you for purchasing this water heater. Properly
installed and maintained, it will provide years of trouble free
service. This manual gives instructions for the proper installation, safe operation and maintenance of this water heater.
It is your responsibility to ensure that your water heater is
properly installed and cared for.
John Wood Oil Fired Water Heaters are designed to supply
domestic hot water for normal residential demands. Any
deviation from this could affect your warranty.
Important Consumer Notice
The warranty on this water heater is in effect only when the
water heater is installed and operated in accordance with
these instructions. The manufacturer of this water heater will
not assume any liability for any property damage or personal injury resulting from failure to comply with these instructions.
Protect your warranty: Regularly service your water heater
as directed in the “Maintenance” section of this manual.
Installation Code Requirements
In addition to the installation instructions found in this manual, the water heater must be installed in accordance with all
local and provincial or state codes or, in the absence of local
and provincial or state codes, with the latest editions of:
“Installation Code for Oil-Burning Equipment (CSA
B139-04)” and
“Canadian Electrical Code Part 1 (C22.1)” (in Canada)
available from:
Canadian Standards Association,
5060 Spectrum Way,
Mississauga, Ontario, Canada
L4W 5N6
or
“Standard for the Installation of Oil-Burning Equipment
(NFPA 31)” and
“National Electrical Code (NFPA 70)” (in USA) available
from:
American National Standards Institute,
25 West 43rd Street,
New York, NY 10036
Important: Installation and service of an oil fired water
heater and burner must be performed by a qualified OilBurner Technician to comply with local and provincial or
state codes applicable to this type of equipment. All supply
equipment, installation, approvals, permits, inspections, etc.
are the responsibility of the owner of this water heater.

area.
IMPORTANT:
This water heater must be installed strictly in accordance
with the instructions enclosed, and local electrical, fuel
and building codes. It is possible that connections to the
water heater, or the water heater itself, may develop
leaks. IT IS THEREFORE IMPERATIVE that the water
heater be installed so that any leakage of the tank or related water piping is directed to an adequate drain in such a
manner that it cannot damage the building, furniture, floor
covering, adjacent areas, lower floors of the structure or
other property subject to water damage. This is particularly important if the water heater is installed in a multi-story
building, on finished flooring or carpeted surfaces. GSW
WILL NOT ASSUME ANY LIABILITY for damage caused
by water leaking from the water heater, pressure relief
valve, or related fittings. Select a location as centralized
within the piping system as possible. In any location
selected, it is recommended that a suitable drain pan be
installed under the water heater. This pan must limit the
water level to a MAXIMUM depth of 45mm (1 3/4 in.) and
have a diameter that is a minimum of 50mm (2 in.) greater
than the diameter of the water heater. Suitable piping shall
connect the drain pan to a properly operating floor drain.
When used with a fuel-fired heater, this drain pan must not
restrict combustion air flow.

Air Requirements
An adequate supply of combustion and ventilation air is
required to:
• Ensure proper combustion.
• Reduce risk of property damage, severe bodily injury or
death from possible flue gas leakage and carbon
monoxide emissions.
Do not install an exhaust fan in the same room as the water
heater.
Satisfactory combustion cannot be sustained in an area that
is not provided with fresh air. Fresh air contains oxygen that
is necessary for proper combustion. If the water heater is
installed in a confined space, sufficient fresh air must be
drawn in from outside of the enclosure.
NOTE: Lack of adequate fresh air supply may cause a
poor flame.
Air Supply
CAUTION
IF AN ALL-HOUSE VENTILATION FAN IS USED, A
SEPARATE OUTSIDE AIR DUCT MUST BE USED AND
DUCTED TO THE FURNACE ROOM AND/OR ROOM
WHERE THE WATER HEATER IS LOCATED.
In Canada:
If the water heater is installed in a house built to the requirements of the “National Building Code of Canada, 1985”,
or a subsequent edition, the space shall be provided with a
air inlets as outlined below, or have a mechanical air-supply
system of sufficient equivalent capacity. If a mechanical airsupply system is used, it shall be interlocked to the appliance or equipment.
NOTE: In unconfined spaces in buildings of conventional
frame, brick, or stone construction built prior to the requirements of the “National Building Code of Canada, 1985”,
and not subsequently significantly air-tightened, infiltration is
normally adequate to provide air for combustion and some
ventilation; however, there may be notable exceptions.
Houses built in accordance with the “National Building
Code of Canada, 1985” (or subsequent edition), with exten-
sive exterior stucco coating, or with a sealed vapour barrier
or other similar air sealing technique, will often be sufficiently airtight so that there is not sufficient air for both combustion and venting the products of combustion of an oil-fired
appliance, or for replacing the air vented by other exhaust
devices within the house.
Outdoor Combustion & Ventilation Air
(Unconfined space)
If the water heater is installed in an unconfined space in a
building having insufficient infiltration, additional air for combustion and ventilation shall be obtained from outdoors or
from spaces freely communicating with the outdoors. Under
these conditions, permanent opening(s) shall be provided so
that the total air received through these openings will be at
least as much as would be admitted by openings having a
total free area of 4.5 cm2/kWh (1 in2/5000 Btu/h) of the total
input rating of all oil-fired appliances.
Outdoor Combustion & Ventilation Air
(Confined space)
A heater installed in a confined space that obtains all of its
air for combustion and ventilation from outside the building
shall be provided with two permanent openings, one near
the top of the enclosure and another near the bottom. Each
opening shall communicate directly or by means of ducts
with the outdoors or to such spaces (such as a crawl space)
that freely communicate with the outdoors, and shall be
sized in accordance with “Air Duct Sizing”.
Outdoor Combustion Air & Indoor Ventilation
Air (Confined space)
An appliance located in a confined space that obtains its
combustion air from outdoors and ventilation air from within
the conditioned space of the building shall be provided with
two permanent openings for ventilation. One located near
the top of the enclosure and another near the bottom. Each
opening shall have a free area of not less than 19.5
cm2/kWh (1 in2/1000 Btu/h) of the total input rating of all
–6–
appliances in the enclosure, freely communicating with interior areas that have in turn adequate infiltration from the outside. It shall also have a combustion air supply opening so
that the total air received through the opening will be at least
as much as would be admitted by openings having a total
free area of 4.5 cm2/kWh (1 in2/5000 Btu/h) of the total input
rating of all oil-fired appliances in the enclosure.
Indoor Combustion & Ventilation Air
(Confined space)
A heater installed in a confined space and that obtains all of
its air for combustion and ventilation from within the conditioned space of the building shall be provided with two permanent openings, one near the top of the enclosure and
another near the bottom. Each opening shall have a free
area of not less than 19.5 cm2/kWh (1 in2/1000 Btu/h) of the
total input rating of all appliances in the enclosure, freely
communicating with interior areas that have in turn adequate
infiltration from the outside.
Air Duct Sizing
The air duct requirements shall be met by one of the following methods:
1. vertical duct(s) with a free area of not less than 5.5
cm2/kWh (1 in2/4000 Btu/h) of the total input rating of all
appliances in the enclosure;
2. horizontal duct(s), with an equivalent length of less than
15 m (50 ft), having a free area of not less than 11
cm2/kWh (1 in2/2000 Btu/h) of the total input of all appliances in the enclosure; and
3. air openings that communicate directly with the outdoors,
having a free area of not less than 5.5 cm2/kWh (1
in2/4000 Btu/h) of the total input rating of all appliances
in the enclosure.
NOTE: Duct runs that are primarily horizontal and that have
an equivalent length greater than 15 m (50 ft) should be
sized accordingly larger to provide the same air flow as
would be provided by the requirements of method (3) above.
In USA:
Refer to “Standard for the Installation of Oil-Burning
Equipment (NFPA 31)”
Vent and Exhaust Connections
General chimney requirements
ing the oil-fired water heater. Inspect existing chimney
before installing the water heater. Failure to do any of the following can result in serious property damage, severe bodily
injury or death:
• Clean the chimney, including removal of blockage.
• Repair or replace damaged pipe or liner.
• Repair mortar and joints.
To prevent downdrafts, extend the chimney at least 1m (3 ft.)
above highest point where it passes through roof and
610mm (24 in.) higher than any portion of building within 3m
(10 ft.). Increase chimney cross-sectional area and height at
least 4% per 305m (1,000 ft.) above sea level.
Flue Pipe
NOTE: Type “L” vent material is generally considered to be
not suitable for this application. Flue temperatures may
exceed 300°C (572°F). Use flue piping approved for this
installation.
Long horizontal flue pipes, excessive number of tees and
elbows or other obstructions restrict flue gas flow, and can
result in the possibility of condensation, flue gas leakage
and carbon monoxide emissions. These conditions can lead
to serious property damage, severe bodily injury or death.
The flue pipe should be the same size as the breech connection on the appliance. The sizes generally are 150mm (6
in.) for burners rated less than 1.00 GPH and 178mm (7 in.)
for burners rated for 1.00 to 1.50 GPH. The flue pipe should
be as short as possible and installed so that it has a continuous rise of 20mm/m (1/4 in./ft.) of horizontal length from the
breech connection on the appliance to the chimney. Elbows
should be minimized and the sections of pipe and fittings
should be joined with sheet metal screws and straps.
Routing should be made in such a way as to avoid sharp
turns or unduly long runs. It is recommended that the heater
be piped to its own individual flue. Where there is only one
flue for both furnace and water heater, various methods are
practiced in which the water heater flue enters the chimney
above the main smoke pipe. Also, a “Y” fitting is frequently
used in combining both the heater and furnace flues, prior to
entering the chimney connection (see Figure 4, check with
local authorities having jurisdiction). Obtain a gas-tight seal
to prevent possible flue gas leakage and carbon monoxide
emissions, which can lead to severe bodily injury or death.
Draft Regulator
For a burner designed for natural draft connect the vent to a
vertical chimney. Insufficient draft can cause flue gas leakage and carbon monoxide emissions, which can lead to
severe bodily injury or death. Use vent material approved by
local codes for oil-fired burners. In the absence of such
codes, refer to:
• “Installation Code for Oil-Burning Equipment (CSA
B139-04)” (Canadian installations).
• “Standard for the Installation of Oil-Burning
Equipment (NFPA 31)” (USA).
• “Standard for Chimneys, Fireplaces, Vents, and
Solid Fuel-Burning Appliances (NFPA 211)” (USA).
NFPA 211 requires the chimney to be lined before connect-
This device is used on conventional chimney venting only. It
automatically maintains a constant negative pressure in the
chimney to obtain maximum efficiency. If the chimney does
not develop sufficient draft, the draft control cannot function
properly. The heater must be equipped with an approved
draft regulator of adequate size. Make sure that the draft
regulator diameter is at least as large as the flue pipe diameter. Follow manufacturers recommended instructions for
installation. It must be installed in the flue pipe before it
enters the chimney and after the Blocked Vent Safety
Switch, if one is used. Set the draft regulator at -0.03 in. (0.762mm) of water column, as measured in the flue
(between the heater and the draft regulator). Recommended
over-fire draft is -0.02 in. (-0.5078mm) of water column.
–7–
Chimney
Be sure that the chimney is sufficiently high and large
enough to meet the specifications of the burner unit
installed. Check that there is sufficient draft for the proper
burning of oil. At least -0.015 in. (-0.381mm) water column
of over-fire draft is recommended.

Burning Equipment (NFPA 31)” (as applicable), local
codes and the manufacturer’s instructions. The burner
should be installed only by a qualified Oil-Burner Technician.
Oil Supply Connections
All aspects of oil tank location and installation, tank size, oil
piping supply and burners, including any fittings, valves, filters or any fuel handling components must comply with:
• “Installation Code for Oil Burning Equipment
(CAN/CSA-B139)”, (Canada).
• “Standard for the Installation of Oil-Burning
Equipment. (NFPA 31)”, (USA).
• Local codes and regulations.
• Information provided with burner and fuel pump.
Install the oil supply tank with fill and vent lines of adequate
capacity as shown in Figure 4. When an appliance using a
float valve between the supply tank and the burner is connected to a supply tank over 9 Canadian gallons capacity, a
valve operated by a fusible link, shall be installed in the fuel
line adjacent to, and upstream from, the float valve. If any
part of fuel oil tank is above level of burner, an anti-siphon
device must be used to prevent flow of oil in case of oil line
break. Support the oil lines as required by applicable codes.
Make tank connections with swing joints or copper tubing to
prevent breaking in case the tank settles. Make the swing
joints so they will tighten as tank settles. Non-hardening pipe
joint compounds should be used on all threads. Do not use
Teflon® tape as an oil pipe sealant. It can cause valves to
fail creating hazards. Do not use compression fittings.
Underground pipe must be run in a casing to prevent oil
leaking into ground or under floor. Check local codes for
more information.
Water Supply Connections
Pipes and fittings should be installed in as shown in the
installation drawing (Figures 7 & 8). Install a shut-off valve in
the cold water supply line in close proximity to the cold inlet
of the water heater. This valve is for use only when servicing the heater and must be kept open during the heater’s
operation. The water connection fittings (nipples) may contain a non-metallic lining to minimize corrosion and some
models include non-metallic heat traps. These appear like
pink or blue coloured plugs in the fitting. Do not attempt to
pry these plugs loose or damage them. DO NOT APPLY
HEAT DIRECTLY TO THE WATER HEATER NIPPLES. If
copper piping is used, solder a piece of tubing to a threaded
adaptor before screwing the adaptor to the nipples. Use only
solder approved for use with potable water systems. Use a
good grade of pipe joint compound, certified for use with
potable water, on the threaded fittings. Be sure all fittings are
drawn up tight.
NOTE: Rear and Combination flue heaters are equipped
with a combination cold water inlet/drain valve.
Temperature and Pressure (T&P) Relief Valve
To reduce the risk of excessive pressures and temperatures
in this water heater, install temperature and pressure protective equipment as required by local codes. It should be no
less than a combination Temperature and Pressure (T&P)
Relief Valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of
listed equipment or materials, as meeting the requirements
of the latest edition of ANSI Z21.22: Requirements for
Relief Valves and Automatic Gas Shut-off Devices for
Hot Water Supply Systems. This valve must be marked
with a maximum set pressure not to exceed the marked
MAXIMUM working pressure of the water heater (150 psi
(1034 kPa). The function of the temperature and pressure
relief valve is to discharge water in quantities, should circumstances demand. To prevent property damage, bodily
injury or hazard to life the relief valve must be allowed to discharge water in the event of excessive temperature or pressure developing in the water heater. If the discharge tube is
not directed to a drain as shown in Figures 7 & 8 or by other
suitable means, the resulting water flow may cause substantial property damage. Install the T&P valve into the
opening provided and marked for this purpose in the water
heater, and orient it or provide tubing so that any discharge
from the cannot contact any live electrical part. Do not connect discharge directly to a drain.
the discharge line:
• must not be smaller than the outlet pipe size of the
relief valve,
• opening must not be threaded, blocked, plugged,
capped, reduced in size or restricted in any manner
under any circumstances,
• must be made of material capable of withstanding
100°C (212°F) without distortion,
• must be installed so as to allow complete drainage of
both the temperature and pressure relief valve and discharge line,
• must terminate near a floor drain or other suitable location not subject to blocking or freezing, and
• must exit only within 150mm (6 in.) above, or at any distance below the structural floor.
NOTE: Rear and Combination flue units must be fitted with
a T&P Relief Valve WATTS type 40XL-5 or equivalent.
Failure to install and maintain a new, properly listed
temperature and pressure relief valve will release the
manufacturer from any claims which may result from
excessive temperature or water pressure.
Closed Water Systems
During the heating cycle of the water heater the water
expands creating a pressure build-up in the water system.
The water supply meter may contain a check valve or back
flow preventer. This will create a closed water system. A
Temperature and Pressure (T&P) Relief Valve (150 psi

Water Temperature Regulation
Once installed, the operation will be completely automatic.
The thermostat (aquastat) on the water heater is adjustable
and will maintain water at the desired temperature.
WARNING
Water temperature over 52°C (125°F) can cause
severe burns instantly or death from scalds.
Children, disabled and elderly are at highest risk of
being scalded.
Feel water before bathing or showering.
Temperature limiting valves are recommended.
WARNING: HOT WATER CAN PRODUCE 3RD DEGREE
BURNS IN 6 SECONDS AT 140oF (60OC) IN 30 SECONDS
AT 130OF (54OC)
Thermostats are factory set at 49°C (120°F). Contact a qualified Oil-Burner Technician for adjustment. Set the tank thermostat as low as possible to provide an adequate supply of
hot water. This will conserve oil and extend the life of the
tank.
V) MAINTENANCE
General
Do not attempt to repair your water heater. Call a qualified
Oil-Burner Technician for service. Turn “OFF” the electric
power whenever the water supply is shut off. Before calling
for service, check that:
1. The heater is properly filled.
2. The electrical supply has not been interrupted.
Professional Maintenance
WARNING
Do not attempt to operate this water heater
with the cold water inlet valve closed.
Manually operate temperature and pressure
relief valve at least once a year. Standing
clear of the outlet, (discharge water will be
hot), lift and release the lever handle on the
temperature and pressure relief valve to
make sure the valve operates freely.
Never operate the heater if it is not completely filled with water. To make sure the
heater is filled, open the hot faucet of an
upstairs tap, until there is a full flow of water
with no air coming through the tap.
Flue Pipes
Once a year, inspect the flue pipe leading from the heater to
the chimney. If corrosion is evident, or discolouration at the
joints can be seen, replace the flue pipes. This should be
done by a qualified Oil-Burner Technician. Flue pipes must
be replaced by the same size flue pipe as the flue collar
(breech connection) at the heater.
Combustion Tests
Burner adjustments:
Final burner adjustments must be made using combustion
test equipment to assure proper operation. Do not fire
heater without water or sections will overheat.
1. Refer to burner manual for start-up.
2. Allow heater to heat to design condition.
3. Using combustion test equipment, adjust burner for:
a. CO2 between 11% and 12% and a trace of smoke
between No. 0 smoke and No. 1 smoke.
b. over-fire draft -0.01 to -0.02 in. (-0.254 to -0.508mm)

If the heater is to remain empty for an extended period of
time, it is suggested the drain valve be left open. When
draining is complete, the hose may be removed.
Perform any other servicing as required.
Close the drain valve and disconnect hose.
Follow instructions for “Filling the Water Heater” and
“Startup” when heater is ready to be put back into service.
Cathodic Protection
Discharge line to drain
Figure 12 T&P VALVE TEST.
WARNING! The temperature and pressure relief valve
must be manually operated at least once a year. Caution
should be taken to ensure that:
1. No one is in front of or around the outlet of the temperature and pressure relief valve discharge line.
2. The water manually discharged will not cause any bodily injury or property damage. The water may be
extremely hot.
If, after manually operating the valve, it fails to completely
reset and continues to release water, immediately close the
cold water supply valve, drain the tank as directed in the
“Draining and Flushing” section, and replace the temperature and pressure relief valve with a new one. Failure to
install and maintain an approved temperature and pressure
relief valve will release the manufacturer from any claim that
might result from excessive temperature or pressure.
Draining, Flushing and Sediment
Removal
Some maintenance and service procedures require that the
heater be drained and empty. The water heater should also
be drained if being shut down for an extended period of time.
Water may contain fine particles of soil and sand which settle to the bottom of a tank and thus form a layer of sediment.
The action of the anode may also help to form sediment. If
not removed, the heater could develop a tendency to pound,
gurgle, or thump when heating up. It is recommended that
the tank be drained and flushed on a regular basis to
remove any sediment that may buildup during operation. To
drain the tank and remove the sediment:
1. Turn "OFF" the electrical supply to the water heater.
2. Close the cold water supply valve.
3. Attach a hose to the drain valve and route to an adequate
drain.
CAUTION! The water being drained can be extremely
hot! The drain hose should be rated for at least 93°C
(200°F). If the drain hose does not have this rating, open the
cold water supply valve and a nearby hot water faucet
served by the system until the water flow is no longer hot.
Close the cold water supply valve and resume.
4. Open the drain valve using a flat-blade screwdriver. A
nearby hot water faucet must be opened to allow the tank
to be fully drained.
5. Open the cold water supply valve and flush the tank as
needed to remove sediment and any other foreign mat-
Your water heater has been equipped with one or more
anodes that protect the glass-lined tank from corrosion and
prolong the life of the water heater. Over time, as the
anode(s) works, it slowly dissolves, exposing the steel inner
core. Once the anode(s) is depleted, the tank will start to
corrode, eventually developing a leak. Depending on water
conditions, an anode(s) can last from one to ten years. Many
localities treat their water and this can have a significant
effect on the life of your heater. Water conditioning, such as
over-softening, can accelerate the rate at which the
anode(s) is consumed. As with any water heater, it is good
practice to check the anode(s) annually to see if it needs
replacing. Do not remove this anode(s) permanently as it
will void any warranties, stated or implied. Rapid depletion or failure to maintain the anode can leave a heater
unprotected and may result in premature failure of the
heater due to corrosion and leaks.
This series of oil fired water heaters are factory equipped
with 1 or 2 anodes, depending on the model. The JW717/
JW727 models are equipped with one heavy duty anode.
Under normal circumstances, these anodes should last the
life of the tank and need not be replaced.
Hot Water Odour
On occasion, and depending on your location, hot water
may develop a strong odour. This can be especially problematic in regions where the water contains sulphur, which
results in hot water having a "rotten egg" odour. If this
occurs, drain the system completely, flush thoroughly and
refill the tank. If the water odour or discoloration persists, the
anode(s) may need to be changed from magnesium to one
made of aluminum. Aluminum anodes may reduce, but not
eliminate, water odour problems. The water supply system
may require special filtration equipment from a water conditioning company to successfully eliminate all water odour
problems. In certain cases chlorinating and flushing of the
water heater may be required. Contact your dealer or water
supplier.
Discoloured Water
•
– 14 –
Water rich in iron or other minerals can produce red or
brown staining. Heating water generally worsens this situation.
•
•
•
•
Black water can be an indication of organic contaminates in the water supply. This can be problematic in
areas where the water is obtained from surface or contaminated sources. Organic particles can develop bacterial growth, causing potential health hazards.
Contact your water supplier for proper filtration or water
conditioning equipment.
For bacterial problems contact your local health authority. See also “Hot Water Odour”.
A sudden appearance of rust-coloured water may indicate that the anode(s) has been depleted. Once depleted, the anode’s inner steel core becomes exposed
causing it to corrode and release iron particles into the
water. See also “Anode Maintenance”.
Anode Maintenance
A new anode is about 20mm (13/16 in.) to 22mm (7/8 in.)
diameter and has a steel wire core approximately 3mm (1/8
in.) diameter in the center. If the anode is less than approximately 10mm (3/8 in.) in diameter, or the inner steel core is
exposed, the anode(s) should be replaced. Operating a
water heater without an actively working anode(s) will void
the warranty.
To

check/replace the anode:
Turn "OFF" the electrical supply to the water heater.
Close the cold water supply valve.
Open a nearby hot water faucet served by the system
to depressurize the system.
4. Connect a hose to the drain valve and drain 22 litres (6
USG.) as directed in “Draining, Flushing and Sediment
Removal”.
CAUTION! The water being drained can be extremely
hot! The drain hose should be rated for at least 93°C
(200°F). If the drain hose does not have this rating, open the
cold water supply valve and a nearby hot water faucet
served by the system until the water flow is no longer hot.
Close the cold water supply valve and resume.
5. Remove the anode cover, or, on JWF657, Rear and
Combination flue models, remove top cover, insulation
and flue top cover.
NOTE: The anode(s) has been factory installed using a
power tool. It may be necessary for a second person to stabilize the heater. A few sharp blows on the handle of the
socket wrench should loosen the anode nut. If an impact
wrench (power drive) is available, this is an easier way to
remove an anode.
6. Using a 1 1/16" socket (certain models require 1-5/16”)
, remove the anode(s) and inspect it. The surface may be
rough, full of pits and crevices, but this is normal. If it is
less than approximately 10mm (3/8 in.) in diameter, or
the inner steel core exposed, the anode(s) should be
replaced.
7. Apply Teflon® tape, or sealing compounds approved for
use with potable water, to the threads of the anode(s)
and install into the tank top.
8. Open the cold water supply valve and open a nearby hot
water faucet to purge air from the water tank as directed
in “Filling the Water Heater”.
9. Check for leaks. Repair as required, and re-test.
10.Replace the covers and insulation and turn the electrical
supply to the heater “ON”.
Cleaning Instructions, Flue Passages Of
The JWF657 Heater
Refer to Figure 13 for components of the heater.
1. Remove the casing top and lift if off completely. It is necessary to disconnect the hot and cold water lines and
move them out of the way. Do not remove the nipples
from the tank.
2. Lift off the flue collector. The flue collector has a lip on
the outer edge which will allow a hook to grab the edge
to help lift it up.
3. Remove the flue baffles (4).
4. With a 76mm (3 in.) diameter wire brush, 1.2m (4 ft.)
long, remove any soot build-up which may be on the top
head or inside the flue collector.
5. Reassemble in reverse order. It may be necessary to
replace the gaskets around the nipples to seal them at
the flue collector. Replace the insulation and the casing
top.

Re-Starting The Heater After Shut-Down
CAUTION
Hydrogen gas can be produced in a hot water system
served by this heater that has not been used for a long
period of time (generally two (2) weeks or more).
Hydrogen gas is extremely flammable and can ignite
when exposed to a spark or flame. To reduce the risk of
injury under these conditions, it is recommended that the
hot water faucet be opened for several minutes at the
kitchen sink before using any electrical appliance connected to the hot water system. Use caution in opening
faucets. When hydrogen is present, there will probably be
an unusual sound such as air escaping through the pipe
as the water begins to flow. There should be no smoking
or open flame near the faucet at the time it is open.
1. Follow instructions for “Filling the Water Heater” and
“Startup” when heater is ready to be put back into service.
2. If the heater does not start, check to see if the relay on
the burner has tripped. Reset if necessary. Check to see
if the thermostat is set at “Normal” or “High”.
3. If the heater does not start:
a) Turn "OFF" the electrical supply to the water heater.
b) Shut off the oil supply at the tank.

This section serves as a guide for the installation and use of
“Combo” heating systems utilizing a domestic water heater
which has been specifically approved for such use. It is written for those knowledgeable in the required trades and professionals involved in the design and installation of Combo
Heating Systems. It is the responsibility of the installer/
designer to follow all applicable codes to ensure the effectiveness and safety of the installation.
CAUTION:
READ BEFORE PROCEEDING
The following requirements must be met for the installation
of Combo Heating Systems:
1. All components used for the distribution of water in the
heating loop must be suitable for potable water. These
include all piping, fittings, solder and fluxes, pumps for
circulation of water, valves, etc.
2. The water heater must not be connected to a hydronic
heating system that has been used previously.
3. No boiler treatment chemicals of any kind shall be introduced into the system.
4. The Combo System components must be selected and
sized to meet and maintain the total calculated demands
for both domestic service hot water and space heating
requirement. The sizing and installation must be performed in accordance with good engineering practice
such as ASHRAE Handbooks, HRAI, Hydronics Institute
Manuals, CGA B149, NFPA 54, ANSI Z223.1, CSA
F280, National/Provincial Building Codes, CSA C22.1,
ANSI/NFPA 70, CSA B51 and/or codes having jurisdiction.
5. The air handler (fan coil) and/or the circulating pump in
a heating loop will require a dedicated 120V circuit. This
must be provided and identified for this purpose.
6. All piping between the water heater and the air handler
or heating loop must be adequately insulated to reduce
heat loss.
7. If the local jurisdiction requires a back-flow preventer in
the cold water line, an expansion tank of adequate size
must be installed.
8. To reduce the scald hazard potential, a mixing valve
must be installed.
Installation
The heating mode may be one of the following options:
1. A fan coil/air handler (Figure 14).
2. A hydronic baseboard (finned tube) loop (Figure 15).
3. A hydronic in-floor heating loop (Figure 16).
In order to connect a heating loop to the water heater you
must:
1. Install shut-off valves and unions so that the water
heater can be isolated from the heating module should
servicing of the water heater become necessary.
2. Install a drain valve at the lowest point of the heating
loop so that water can be drained from the heating module without affecting the water heater.
• If the air handler does not have a venting means, install
an air bleed at the highest point of the plumbing
arrangement.
• If solenoid valves are used for zone heating applications, they must include electrical proof of valve full open
position and must be connected to the water pump.
