•
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.

Burn Hazard
If the space heating system requires water
temperatures in excess of 129 °F, install
thermostatic mixing valves according to the
manufacturer’s instructions, in the potable hot
water supply at each point of use to limit the
risk of scald injury.
