□ Ensure that hot and cold water lines are not
crossed to the unit and are leak free.
□ A manual gas control valve has been placed in the
gas line to the water heater.
□ 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.
□ Clean the inlet water lter(s) by closing the cold
and hot water inlet isolaon (shut-o) valves. Put
a bucket under the lter(s) at the boom of the
water heater to catch any water that is contained
inside the unit. Unscrew the water lter(s) .
Rinse the lter(s) to remove any debris. Install
the lter(s) and open the isolaon valves.
□ If installed in an applicaon using thermal by-pass
valve, remember to remove plug and replace with
the supplied lter (located within the unit). 
discard the plug. Plug is to be retained
should the applicaon be changed to a dedicated
return in the future.
□ Purge air from recirculaon line.
□ 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.
□ Verify that SW 2 and SW 3 in DIPSW 1 is set
correctly for your altude.
□ Ensure Dip Switch sengs are properly set for the
desired recirculaon mode.
□ 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.
□ Inform the consumer if the isolaon valves are
not installed or if a water soening system is not
