•
Install vent system in accordance with codes.
•
Do not operate water heater if any part has been
exposed to flooding or water damage.
•
High altitude models should be installed at elevations
above 5,300 feet ( 1,615 m ). For operation above 10,100
feet (3,079 m), a high altitude orifice must be installed.
•
Do not operate if soot buildup is present.

drain line beyond the 1/2” adaptor above the
adaptor. This must be true for the entire length
of the drain line including the exit into an
appropriate drain.
•
Condensate lines must be free and clear of debris
and must not allow back flow through the hose.
The condensate lines must be able to flow freely
to an appropriate drain.
•
Do not obstruct water heater air intake with
insulating jacket.
•
Do not place chemical vapor emitting products
near water heater.
•
Do not allow condensate lines to become
crimped closed.
•
Analyze the entire vent system to make sure
that condensate will not become trapped in a
section of vent pipe and therefore reduce the open
cross sectional area of the vent.
•
Gas and carbon monoxide detectors are available.
•
No vent damper installation is compatible with
this power vented water heater.
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.

Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other appliance.
Use only the gas shown on the water heater rating label.
Keep ignition sources away from faucets after extended

Maintain required clearances to combustibles.
Do not expose water heater controls to excessive gas
pressure.

Do not install the water heater where flamable products will be
stored or used unless the main burner and hot surface igniter
are at least 18” (457 cm) above the floor. This will reduce, but
not eliminate the risk of vapors being ignited by the main
burner or hot surface igniter.
