Final Checklist

□
The water heater is not subject to corrosive
compounds in the air.
□
The water supply does not contain chemicals or
exceed total hardness that will damage the heat
exchanger.
□
Clearances from the water heater unit are met.
□
Clearances from the vent termination / air intake
are met.
□
For indoor models, ensure you have used the
correct venting products for the model installed
and that you have completely followed the
venting manufacturer's installation instructions
and these installation instructions.
□
For indoor models, verify that the vent system
does not exceed the maximum length for the
number of elbows used.
□
For indoor models verify that switch No. 1 in the
SW1 DIP switch (tan switches) has been adjusted
for vent length if necessary. Refer to the section
on Maximum Vent Length.
□
For indoor models, verify that the vent pipe has a
downward slope or grade to the outside of 1/4
inch per foot (1.2° ) OR, if the vent pipe is sloped
toward the water heater (as some local codes
require), that a condensate collector is installed
to allow condensation to drain away from the
water heater to a proper drain source.
□
For indoor models, verify that condensate will not
be allowed to drain back into the water heater.
□
Purge the water line of all debris and air by
closing the hot isolation valve and opening the
cold isolation valve and its drain. Debris will
damage the water heater. Use a bucket or hose
if necessary.
□
Ensure that hot and cold water lines are not
crossed to the unit and are leak free.
□
Clean the inlet water filter by closing the cold and
hot water inlet isolation (shut-off) valves. Put a
bucket under the filter at the bottom of the water
heater to catch any water that is contained inside
the unit. Unscrew the water filter. Rinse the
filter to remove any debris. Install the filter and
open the isolation valves.
□
Ensure that a pressure relief valve is installed with
a rating that exceeds the BTU input of the water
heater model. Refer to the rating plate on the
side of the water heater for BTU input.
□
A manual gas control valve has been placed in the
gas line to the water heater.
24
□
Check the gas lines and connections for leaks.
□
Confirm that the gas inlet pressure is within
limits.
□
Confirm that the water heater is rated for the gas
type supplied.
□
Confirm that the electricity is supplied from a 120
VAC, 60 Hz power source, is in a properly
grounded circuit, and turned on.
□
Verify the temperature controller is functioning
properly.
□
Verify that switches No. 2 and No. 3 in the SW1
DIP switch (tan switches) is set correctly for your
altitude.
□
Verify the system is functioning correctly by
connecting your manometer to the gas pressure
test port on the water heater. Operate all gas
appliances in the home or facility at high fire. The
inlet gas pressure at the water heater must not
drop below that listed on the rating plate.
□
DO NOT introduce toxic chemicals such as those
used for boiler water treatment to the potable
water used for space heating.
□
If the water heater is not needed for immediate
use, then drain the water from the heat
exchanger.
□
Install the front panel.
□
Explain to the customer the importance of not
blocking the vent termination or air intake.
□
Explain to the customer the operation of the
water heater, safety guidelines, maintenance, and
warranty.
□

The installation must conform with local codes or,

in the absence of local codes, with the National

Fuel Gas Code, ANSI Z223.1/NFPA 54, or the
Natural Gas and Propane Installation Code, CSA
B149.1. If installed in a manufactured home, the
installation must conform with the Manufactured

Home Construction and Safety Standard, Title 24

CFR, Part 3280 and/or CAN/SCA Z240 MH Series,

Mobile Homes.

□
Inform the consumer if the isolation valves are
not installed or if a water softening system is not
installed.
□
Leave the entire manual taped to the water
heater (indoor models), temperature controller
(outdoor models), or give the entire manual
directly to the consumer.
