SAFETY
IMPORTANT SAFETY INFORMATION
requirements for Relief Valves for Hot
Water Supply Systems, ANSI Z21.22.
The T&P Relief Valve’s relief pressure
must not exceed the working pressure
ra ng of the water heater as stated on
the ra ng plate.
Maintain the T&P Relief Valve properly.
Follow the maintenance instruc ons
provided by the manufacturer of the
T&P Relief Valve (label a ached to T&P
Relief Valve). An explosion could occur
if the T&P Relief Valve or discharge
pipe is blocked. Do not cap or plug the
T&P Relief Valve or discharge pipe.
Fire and Explosion Risk if Hot Water is
Not Used for Two Weeks or More.
CAUTION! Hydrogen gas builds up
in a hot water system when it is not
used for a long period (two weeks or
more). Hydrogen gas is extremely
fl ammable. If the hot water system
has not been used for two weeks or
more, open a hot water faucet for
several minutes at the kitchen sink
before using any electrical appliances
connected to the hot water system. If
hydrogen is present there will
probably be an unusual sound such as
“air” escaping through the pipe as hot
water begins to fl ow. Do not smoke or
have an open fl ame or other igni on
source near the faucet while it is
open.
Carbon Monoxide Risk
WARNING! This water heater
operates by burning gas.
Carbon monoxide is a
colorless, odorless
gas that is a by-
product of burning of
fuels such as coal,
wood, charcoal, oil,
kerosene, propane, and natural gas.
Breathing excessive and abnormal
amounts of carbon monoxide can
cause carbon monoxide poisoning,
resul ng in serious injury or death.
This water heater must be supplied
with adequate combus on air and
must be properly vented to the
outdoors. Have a qualifi ed person
(licensed plumber, authorized gas
company personnel, or authorized
service technician) install the ven ng
system using these installa on
instruc ons as well as those provided
by the roof jack manufacturer. When
the installa on is complete, check the
vent’s dra using the instruc ons on
page 22.
• Install a fuel gas and carbon
monoxide detector in the living
areas of your home.
• Do not install this water heater
in the occupied space of the
manufactured (mobile) home.
• Failure to follow these instruc ons
can result in serious injury or
death from carbon monoxide
poisoning.
Burn Risk
This water heater’s
ven ng system can
become hot enough to burn. Do not
touch the ven ng system while water
heater is on, or un l the water heater
is turned off and the ven ng allowed
to cool.
