space for service and maintenance access. For

regular maintenance, gas and water lines must be

accessible.

The boiler must be installed on a wall that can bear its weight.

WARNING

CLEARANCES FOR SERVICE ACCESS

• If you do not provide the minimum clearances

shown, it might not be possible to service the

boiler without removing it from the space.

• Space must be provided with combustion /

ventilation air openings correctly sized for

all other appliances located in the same

space as the boiler. The boiler cover must be

securely fastened to prevent it from drawing

air from the boiler room. This is particularly

important if the boiler is in a room with other

appliances. Failure to comply with the above

warnings could result in substantial property

damage, severe personal injury, or death.

4.2 Wall Mount Bracket

• 4.2.1 The installation height and location for your

FT depends on your installation scenario. With all clearances

considered, and given adequate positioning for air supply

and venting, you will need to determine the best position

to mount the Wall Mount Bracket. The wall must be

concrete, wood, or plywood over studs, and must be

strong enough to hold the boiler!

• Start by familiarizing yourself to how the

included Wall Mount Bracket hooks underneath

the two Hangers that are attached to the back of

the boiler. The ‘hooks’ of the Wall Mount Bracket will

be 3” from the Top of the boiler once the boiler is hung.

• Position the Wall Mount Bracket at the location that it will go,

being sure that it is level, and then drill 4 holes (0.47”dia)

with a 1/2” drill bit, into the wall through the Bracket.

• If mounting to a concrete wall, then use the concrete anchors.

If onto wood or 5/8” (16 mm) plywood, then use the wood

screws. Do not hang the FT onto sheetrock unless it is

possible to fasten directly into

the structural studs. If the

included anchors do not suit

your installation, you must use

‘Field Supplied’ anchors that

are appropriate for the wall’s

construction. Wall Mount

Installation (continued)

4.3 Combustion Air

FT boilers must have provisions for combustion

and ventilation air in accordance with the applicable

requirements for Combustion Air Supply and Ventilation

in the National Fuel Gas Code, ANSI Z223 1; or in

Canada, the Natural Gas and Propane Installation Code,

CSA B149.1. All applicable provisions of local building

codes must also be adhered to.

A FT unit can take combustion air from the space

in which it is installed, or the combustion air can be

ducted directly to the unit. Ventilation air must be

provided in either case.

4.3.1 Combustion Air from Room

In the United States, the most common requirements

specify that the space shall communicate with the

outdoors in accordance with method 1 or 2, which follow.

Where ducts are used, they shall be of the same cross-

sectional area as the free area of the openings to which

they connect.

Method 1: Two permanent openings, one commencing

within 12” (300mm) of the top and one commencing

within 12” (300mm) of the bottom, of the enclosure

shall be provided. The openings shall communicate

directly, or by ducts, with the outdoors or spaces

that freely communicate with the outdoors. When

directly communicating with the outdoors, or when

communicating to the outdoors through vertical ducts,

each opening shall have a minimum free area of 1

square inch per 4000 Btu/hr (550 square mm/kW) of

total input rating of all equipment in the enclosure. When

communicating to the outdoors through horizontal ducts,

each opening shall have a minimum free area of not

less than 1 square inch per 2000 Btu/hr (1100 square

mm/kW) of total input rating of all equipment in the

enclosure.

Method 2: One permanent opening, commencing

within 12” (300mm) of the top of the enclosure, shall

be permitted. The opening shall directly communicate

with the outdoors or shall communicate through a

vertical or horizontal duct to the outdoors or spaces

that directly communicate with the outdoors and shall

have a minimum free area of 1 square inch per 3000

Btu/hr (734 square mm/kW) of the total input rating of

all equipment located in the enclosure. This opening

must not be less than the sum of the areas of all vent

connectors in the conned space.

Other methods of introducing combustion and

ventilation air are acceptable, providing they conform to

the requirements in the applicable codes listed above.

In Canada, consult local building and safety codes or, in

absence of such requirements, follow CAN/CGA B149.1

4.3.2 Ducted Combustion Air

The combustion air can be taken through the wall, or

through the roof. When taken from the wall, it must be

taken from out-of-doors by means of the horizontal wall

terminal. When taken from the roof, a eld-supplied rain

cap or an elbow arrangement must be used to prevent

entry of rain water.

Use ABS, PVC, CPVC, polypropylene, or galvanized

pipe for the combustion air intake. Route the intake

to the boiler as directly as possible. Seal all joints.

Provide adequate hangers. The unit must not support

the weight of the combustion air intake pipe. Maximum

linear pipe length allowed is shown in Table 6. Subtract

5 allowable linear ft. (1.5m) for every elbow used.

The connection for the intake air pipe is at the top of

the unit.

In addition to air needed for combustion, air shall also

be supplied for ventilation, including air required for

comfort and proper working conditions for personnel.

The FT Series Wall Mounted, Combination Boiler Page 19

The FT is standard as a Natural Gas Boiler and

must be converted if propane is the desired gas, unless

specically manufactured for propane.

Adequate drainage

• The appliance should be installed not to damage

the adjacent area. If such locations cannot be

avoided, it is recommended that a suitable drain

pan, adequately drained, be installed under the

appliance. The pan must not block combustion air

ow.

Connecting the Water Supply

• To conserve water and energy, insulate all water

piping—especially the hot and recirculation water

lines. Never cover the drain or pressure relief valve.

Having a backow preventer in the cold water

supply line will prevent thermal expansion

backow. Contact the water supplier or local

plumbing inspector for information about how to

control this situation.

If overheating occurs or the gas supply fails to shut

off, turn off the manual gas valve.

This installation must conform with below section

• “Air for Combustion and Ventilation” of the

National Fuel Gas Code, ANSI Z224.1/NFPA 54,

or Sections 8.2, 8.3 or 8.4 of Natural Gas and

Propane Installation Code, CAN/CSA B149.1, or

applicable provisions of the local building codes.

nearby equipment. Attach the discharge line to the

pressure relief valve and run the end of the line within

6-12″ (150-300mm) of the oor.

WARNING

DO NOT install a CH pipe line relief valve with a

pressure higher than 30psi and DHW pipe line relief

valve with a pressure higher than 150psi. This is

the maximum allowable relief valve setting for the

combination boiler.

Test the operation of the valve after lling and

pressurizing system by lifting the lever. Make sure the

valve discharges freely. If the valve fails to operate

correctly, replace it with a new relief valve. Ensure that

the discharge capacity of the pressure relief valve is

equal to or greater than the maximum pressure rating

of the combination boiler.

Condensate

drain pipe (View is as if side panel

were removed)

Condensate

Trap

High efciency gas condensing Boilers create

condensation when operating. Condensation has

acidic (pH) of approximately 4-5.

Condensate must be drained in accordance with all

local regulations. Follow your local code with regards

to the disposal of condensation.

One of 4 disposal methods must be followed

1.tooordrain

2. to neutralizer (optional kit)

3. to laundry tub

4.tocondensatepump(eldsupplied)

If a neutralizer is installed, periodic replacement of the

lime stone (or neutralizing agent) will be required. The

rate of depletion of the lime stone varies upon usage

of the boiler. During the rst year of operation, please

check the neutralizer every few months for depletion.

Apply only corrosion-resistant materials for the

condensate drain lines such as 1/2˝ PVC, CPVC,

Polypropylene pipe or included plastic hose.

NOTICE

For Category II and IV boilers, be installed so as to

prevent accumulation of condensate; and

For Category II and IV boilers, where necessary, have

means provided for drainage of condensate.

AVIS

les chaudières de catégories II et IV doivent être

installées de façon à empêcher l'accumulation de

condensat; et

si nécessaire, les chaudières de catégories II et IV

doivent être pourvues de dispositifs d'évacuation du

condensat.

CAUTION

Condensate is mildly acidic (pH=5), and may harm

some oor drains and/or pipes, particularly those

that are metal. Ensure that the drain, drainpipe, and

anything that will come in contact with the condensate

can withstand the acidity, or neutralize the condensate

before disposal. Damage caused by failure to install

a neutralizer kit or to adequately treat condensate

will not be the manufacturer’s responsibility.

5.9 Outdoor Reset Adjustment

SECTION 5. Control Display and Operation

5.10 External Set Point Temperature Control

Outdoor Reset varies the control setpoint based on

the outdoor temperature. The reset function works

as shown in Figure ‘CH Outdoor Reset’. When the

outdoor air temperature reaches 6:OH “high outdoor

temperature setpoint”, the control point setting is

adjusted to 17:cL “low boiler temperature setpoint”.

When the outdoor air temperature reaches 7:OL “low

outdoor temperature setpoint” the control setpoint is

adjusted to 16:cH “high boiler temperature”.

Default outdoor reset setpoint is 100°F (38°C)

A signal from a building management system may be connected to the appliance to enable remote

control. This signal should be a 0-10 volt DC signal. When this input is enabled, a building control

system can be used to control the set point temperature of the appliance.

The control interprets the 0-10 volt signal as follows; when the signal is between 0 and 1.5 volts, the

appliance will be in standby mode, not ring.

When the signal rises above 1.5 volts, the appliance will ignite. As the signal continues to rise

towards its maximum of 10 volts, the appliance will increase in set point temperature. Adjust 16:cH

and 17:cL to set MIN and MAX boiler water temperatures respectively.

Connect a building management system or other auxiliary control signal to the terminals marked

for this purpose on the appliance terminal block (shown in Piping Diagrams, this manual). Caution

should be used to ensure that the 0-10 VOLT + connection does not become connected to ground.

Connect to terminal strip as outlined 4.17 Electrical Connections.

NOTE: 0 - 10VDC terminals may not be used for both outdoor reset and 0 - 10VDC temp

setpoint simultaneously.

The Outdoor Temperature Mode Icon on the display

will ash if an Outdoor Sensor or 0-10 Volt is not

connected to the appliance.

To check the CH Target Temperature while using

Outdoor Temperature Mode, press the button

while the appliance is operational and the display

panel is powered on.
