Important Information About
Your Water Heater
This gas water heater was manufactured to voluntary
safety standards to reduce the likelihood of a flammable
vapor ignition incident. New technology used in meeting
these standards makes this product less tolerant of
installation errors or improper installation environments.
Please review the following information and make any
necessary installation upgrades or changes:
1. Check for insufficient combustion air. Insufficient
air for the combustion of gas will result in the flame
becoming “lazy,” thereby allowing heat to build up in
the combustion chamber. This excessive heat will
cause a thermal switch on the door assembly to trip.
Is the water heater installed in a closet or other small,
enclosed space? If so:
•
Are there openings for make-up air to enter and
exit the room/area?
•
Are the openings of sufficient size? Remember,
if there are other gas-fired or air-consuming
appliances in the same room, you need more
make-up air. Refer to the Location Requirements
section of this water heater manual for specific
requirements.
•
Is there a furnace/air handler in the same room/
space as the water heater? If so, has a return air
duct system been attached that exits the room?
If so, check for leaks on the air duct system. If no
air duct system is present, correct immediately
by contacting a local Heating, Ventilation, Air-
Conditioning & Refrigeration (HVAC-R) authorized
service provider.
2. Check for proper drafting at the water heater draft
hood. Refer to the “Checking the Draft” section of this
manual for the test procedure. If the procedure shows
no draft is present:
• Recheck
#1.
•
Check the vent system for restrictions/obstructions
and check the vent termination height. Refer to
the Air Supply and Ventilation section of this water
heater manual for specific requirements.
3. Is the installed environment dirty (excessive amounts
of lint, dirt, dust, etc.)? If so, make sure the flame
arrestor located on the bottom of the water heater
has been cleaned. Refer to the Maintenance of your
Water Heater section of this manual for information on
cleaning the flame-trap.
4. Is it possible that flammable vapors entered the
water heater and were ignited in the burner area (a
flammable vapor incident)? If a flammable vapor
incident has occurred or if you are unsure whether it
has, call the number below immediately.
Proper installation will ensure the safe, effective and
efficient operation of the water heater. Make sure that
you review and follow the instructions in this manual.
