Warning For Installations
FOR YOUR SAFETY, READ
BEFORE INSTALLATION
Do not install the heater
where water, debris or flam-
mable vapors may get into
the flue terminal. This may
cause damage to the heater
and void the warranty. Do not have the vent ter-
minal pointing toward any
opening into a building. Do
not locate your heater in a
pit or location where gas
and water can accumulate.
Do not install next to a dryer
or any source of airborne
debris that can be trapped
inside the combustion
chamber, unless the system
is direct vented.
