Final Checklist
□ The water heater is not subject to corrosive
compounds in the air.
□ The water supply does not contain chemicals or
exceeds total hardness that will damage the heat
exchanger.
□ Clearances from the water heater unit are met.
□ Clearances from the vent terminaon / air intake
are met.
□ For indoor models, ensure you have used the
correct venng products for the model installed
and that you have completely followed the
venng manufacturer’s installaon instrucons
and these installaon instrucons.
□ 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 secon
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 condensaon 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 isolaon valve and opening the
cold isolaon 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 lter by closing the cold and
hot water inlet isolaon (shut-o) valves. Put a
bucket under the lter at the boom of the water
heater to catch any water that is contained inside
the unit. Unscrew the water lter. Rinse the
lter to remove any debris. Install the lter and
open the isolaon valves.
□ Ensure that a pressure relief valve is installed with
a rang that exceeds the BTU input of the water
heater model. Refer to the rang 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.
□ Check the gas lines and connecons for leaks.
□ Conrm that the gas inlet pressure is within
limits.
□ Conrm that the water heater is rated for the gas
type supplied.
□ Conrm 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 funconing
properly.
□ For the V75i/e, verify that switches No. 2 and No.
3 in the SW1 DIP switch (tan switches) is set
correctly for your altude.
□ Verify the system is funconing correctly by
connecng your manometer to the gas pressure
test port on the water heater. Operate all gas
appliances in the home or facility at high re. The
inlet gas pressure at the water heater must not
drop below that listed on the rang plate.
□ 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 terminaon or air intake.
□ Explain to the customer the operaon of the
water heater, safety guidelines, maintenance, and
warranty.
□ The installaon must conform with local codes or,
in the absence of local codes, with the Naonal
Fuel Gas Code, ANSI Z223.1/NFPA 54, or the
Natural Gas and Propane Installaon Code, CSA
B149.1. If installed in a manufactured home, the
installaon must conform with the Manufactured
Home Construcon and Safety Standard, Title 24
CFR, Part 3280 and/or CAN/SCA Z240 MH Series,
Mobile Homes.
□ Leave the enre manual taped to the water
