SECTION II: GENERAL INFORMATION
LOCATION
The indirect coil tank water heater should be located in a central location to the piping
system, as close as practical to the boiler and in an area not subject to freezing temperatures.
Leave sufficient space for servicing and maintaining the heater.
Note: Long heating supply runs can lengthen recovery times.

WATER TREATMENT/FILTRATION
In areas where poor water conditions are suspected (i.e. lime, iron, and other minerals), it is
essential that the water be tested and appropriate action taken to prevent damage to the
indirect heater and ensure the quality of the water.

TEMPERATURE CONTROL
Water temperature from the heat source / boiler to the indirect coil tank water heater is
controlled by an immersion aquastat. This control operates the circulator, and provides
limited control for domestic hot water temperature. The proper temperature setting for
domestic hot water use is 120°F/49°C. If hotter water is required a tempering device or
anti-scald device must be installed at the domestic hot water outlet of the heater or at the
point of use.

CAUTION: Hot water in excess of 120°F
can cause scalding!
HotLine recommends a tempering valve or anti-scald valve be installed and used according
to the manufacturer’s directions to prevent scalding. Many state and local codes now require
installation of these devices. The tempering valve or anti-scald valve will ensure potable
water temperatures at the desired set point with a higher degree of accuracy.

SECTION II: GENERAL INFORMATION (cont.)
ANODE RODS
The anode rod is used as a sacrificial element within the volume of the storage tank. The
purpose of the magnesium anode rod is to protect the inside of the tank against corrosion.
Anode rods should be inspected twice in the first year and at least yearly once a time interval
for inspection has been developed. Water conditions can influence the consumption rate of
the anode rods. Please see the Maintenance section of this manual for instructions on how to
change the anode rods in your Hot Line water heater.
CAUTION: Hydrogen gas is produced in a hot water system served by this heater that has not been used for
a long period of time (2 weeks or more). Hydrogen gas is extremely flammable. 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. 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 (UL 174).

TEMPERAURE AND PRESSURE RELIEF VALUE (T&P)
The T&P valve is factory installed. A discharge drain tube must be installed (responsibility of
the installer) and shall terminate plain, not threaded, 6 inches above the floor drain. The
drain tube material must be approved for temperatures of 120°F or greater, and a pressure of
150 PSI or greater.

BACK-FLOW PREVENTOR (CLOSED LOOP SYSTEM)
Some local municipal codes and ordinances require the use of these devices on potable
(domestic) water lines. Where back-flow preventors are required, it will be necessary to
install a thermal expansion tank (designed for used with potable water) in order to prevent
pressure build up in the indirect heater and associated piping, which could cause the T&P
valve to discharge. Follow the expansion tank manufacturer’s recommendations when
selecting a tank for your hot water system.
Note: Working pressure of the water heater is 150 PSI. Do not exceed 150 PSI.

Page 7

SECTION III: PRE-INSTALLATION
BOILER AND CIRCULATOR SIZING
The ratings published in this manual for your HotLine Indirect Coil Tank Water Heater can
be obtained through proper selection of boiler output and circulator capacity. As noted, the
ratings in Table 2 are based on a 77°F rise with 58°F potable water inlet temperature at a
circulator pump flow rate of 8 GPM. The boiler was set at 180°F. See Table 3 for additional
first hour ratings at pump flow rates of 6, 8, 10 and 12 GPM with 180°F and 200°F boiler
water.
To determine the appropriate circulator for your system, follow these three steps:
1) Calculate the pressure drop of all straight pipe and fittings on the supply and return at the
desired flow rate.
2) Add the pressure drop from Step 1 to the pressure drop through the indirect coil tank
water heater coil (see Table 2 for friction loss) to obtain a total pressure drop.
3) Select a circulator pump that will provide adequate flow at the total pressure drop.
A pump performance curve should accompany every circulator pump. Figures 3-5 contain
performance curves for Taco and Grundfos circulator pumps, recommended by HotLine.

Figure 4: GRUNDFOS UP 15-42F performance curve

UP 26-64F
Closed Systems, 60 Hz

Figure 5: GRUNDFOS UP 26-64F performance curve
Note: Zone valves on the heat source supply to the indirect heater are not recommended
and will drastically reduce performance.
System performance can also vary based on the heating capacity of the boiler. If the
minimum coil output (assume coil output = boiler output) listed in Tables 2 and 3 is not met,
the output (first hour rating) of the water heater will not be met at the selected flow rate.
To approximate the reduction in first hour rating as a result of low boiler capacity, use the
following formula:
New first hour rating = (First hour rating) * (Actual boiler output)/(Minimum coil output)
For example, the first hour rating of a 50SK at a 77°F rise with an 8 GPM heat source flow rate
using a boiler having a DOE heating capacity (output) of 60,000 BTU/Hr would be:
New first hour rating = (160 gal) * (60,000 BTU/Hr)/(77,000 BTU/Hr) = 125 gal

Page 9

SECTION IV: INSTALLATION
WATER CONNECTIONS
All piping between the boiler and the indirect heater should be new copper with a
minimum size of 3/4” ID for models HL30SK, HL40SK, and HL50SK. Use 1” minimum copper
for models HL80SK and HL119SK. Elbows should be minimized. A flow check valve must be
installed on the return line.
All piping to the inlet (cold) and outlet (hot) domestic water connections should be new
copper with a minimum size of 1/2” ID for models HL30SK, HL40SK, and HL50SK. Use 3/4”
ID minimum for models HL80SK and HL119SK.
All piping should conform to local codes and ordinances. At a minimum, refer to IHLR 84
code if local codes are not in place. It is recommended that all piping be adequately
insulated with approved material to ensure minimum heat loss. If a re-circulation line is
used for domestic water, be certain that all lines are well insulated and the circulator is
temperature controlled. Install isolation valves to permit proper servicing. It is also

ELECTRICAL CONNECTIONS

Figure 9: Boiler Maintaining 180°F

Figures 9 and 10 are general wiring diagrams.
For a maintaining temperature boiler, Figure 9
should closely match your system. For cold start
boilers your wiring may resemble Figure 10, but
will vary depending on the boiler type and
controls or relays used. It is not possible to list all
wiring variations here. When connecting to a cold
start boiler, always remember that in principle an
indirect coil tank heater operates as another
heating zone. The difference is when the indirect
calls for heat, the indirect coil tank heater
circulator must start rather than opening a zone
valve; the system circulator stays off; and the
boiler must light to reach high limit.
WIRING NOTES:
1. Dashed lines indicate low voltage (24 VAC)
2. Use jumper wire between terminals #1 and #3

SECTION V: MAINTENANCE
WATER PIPING
On an annual basis, all piping should be checked for leakage at joints, shut-off valves, and
unions.

T&P RELIEF VALVE
On an annual basis, the temperature and pressure relief valve should be checked for proper
operation. First, attach a drain line to the valve to direct the water discharge to an open
drain. This is very important because the temperature of the discharge could be very hot.
Second, lift the lever at the end of the valve several times. The valve should operate freely
and return to its original position properly. If water does not flow out of the valve, remove
and inspect for corrosion or obstructions. Replace with a new valve if necessary. Do not
repair the faulty valve as this may cause improper operation.

ANODE RODS
Anode rods should be inspected twice in the first year and at least yearly once a time interval
for inspection has been developed. It is recommended to check the rod(s) six months after
the heater is installed. If the anode rod had reduced in size by two-thirds of its original
diameter of 3/4” or shows signs of pitting, it is time for replacement. Take the following
steps when changing the anode rod(s):
1. Shut off water supply.
2. Open any faucet to relieve tank pressure.
3. Remove caps on water heater top; push insulation aside.
4. Use a 1 1/16” six-sided socket wrench and a breaker bar. Snap hard to break the anode
rod seal.
5. Remove rod(s) and replace with new rod(s).
6. Turn water supply back on and leave faucet open until air is out of line.
7. Turn faucet off and check that new rod(s) doesn’t leak.
8. Snap caps back into place.

FLUSH THE TANK
The indirect coil tank water heater is glass lined. Elements in the water such as lime, iron
and other minerals may accumulate in the heater. It is recommended that the tank be
drained and flushed thoroughly once a year to prevent buildup in the tank.

SECTION VIII: WARRANTY
LIMITED LIFETIME WARRANTY
GENERAL CONDITIONS
Hot Line Water Heaters, ECR International, warrants that the
Hot Line tank shall be free of defects in material and workmanship during normal use and service for as long as the original
residential purchaser owns the home in which the unit was originally installed. For the purposes of this Limited Warranty, residential purchaser is defined as the owner of a single family
home in which the purchaser resides on a permanent basis.
If at the time of a request for warranty the original residential
purchaser can not provide a copy of the original sales receipt,
deed, or equivalent document, then the warranty period for the
Hot Line shall be seven (7) years from the date of manufacture
of the unit. The Limited Warranty on the tank shall be reduced
to a period of three (3) years if the purchaser is a business, partnership or corporation, or if the water heater is used for a commercial or multi-family residential property application.
Should a leak develop within this Limited Warranty period due
to defective materials or workmanship and such leak having
been verified by an authorized company representative, ECR
International will repair the unit or furnish a replacement Hot
Line heater or the nearest comparable model available at the
time of replacement.
ECR International shall not be liable for any water damage
arising directly or indirectly from any defect in the water
heater or component part(s) or from the use thereof or any
service call not involving malfunction or defects in materials or
workmanship.

THIS WARRANTY IS VOID AND SHALL NOT APPLY IF:
1) The unit is not correctly installed according to the installation instructions provided with the unit.
2) The residential indirect-fired water heater is installed in
buildings other than one or two family dwelling units, unless
the buildings contain individual indirect-fired water heaters
for each dwelling unit.
3) The indirect-fired water heater is operated at water temperatures of more than 125 degrees F. and water pressure of
more than 150 PSI.
4) The failure or malfunction results from improper or negligent operation, accident, abuse (including freezing), misuse,
unauthorized alteration, improper repair or maintenance,
excessive pressure or leaks at water connections or any other
similar cause.
5) The failure or malfunction results from failure to keep the
unit full of potable water, free to circulate at all times; or failure due to water sediment or scale deposits.
6) The original serial number of the water heater cannot
readily be determined.

7) ECR International Hot Line is installed outside of the
United States or Canada.
8) ECR International Hot Line is repaired or altered without
prior written approval of ECR International and this service adversely affects the product’s reliability.
9) The malfunction or repairs result from the use of ECR International Hot Line for purposes other than that for which it
was designed or any malfuction resulting from flood, fire,
wind or lightning.
ECR International will provide, under the Limited Warranty,
only a replacement water heater, repairs, or parts for defective units. The Limited Warranty does not cover any component of ECR International Hot Line that has to be replaced
during the warranty period as a result of reasonable wear
and tear, labor costs, shipping charges, delivery expenses,
nor administrative fees incurred by the customer in removing
or reinstalling the Hot Line.
In no event shall ECR International be liable for incidental or
consequential damages. Some states do not allow the exclusion
or limitation of incidental or consequential damages, so the
above limitation or exclusion may not apply to you.
In order to gain coverage under this Limited Lifetime Warranty, the consumer is required to fill out and mail the Limited
Warranty registration card provided with the unit by registered mail within 30 days of purchase.
To submit a warranty claim, contact the dealer who sold the
Hot Line covered by this Limited Warranty. If the dealer cannot be located, contact ECR International at the address
shown below. Whenever any inquiry or service request is
made, please include the Hot Line model number, serial number, date of installation, and dealer’s name.
No warranty, express or implied, other than the foregoing Limited Warranty is authorized by ECR International and no representative of ECR International or of the manufacturer of any
component has the authority to amend, extend, modify, enlarge
or contract the foregoing Limited Warranty and the disclaimers
of the Limited Warranty in any manner whatsoever.
