operation or connected to a power or fuel supply.
4.
This heater may be installed in areas subject to
washdown. This heater may only be washed on the
external case assembly—see Cleaning Instructions.
Do not wash the interior of the heater. Use only
compressed air, soft brush or dry cloth to clean the
interior of the heater and it’s components. After
external washdown, do not operate this heater until it
is completely dry. In any event, do not operate the
heater for at least one hour after external washdown.
5.
For safety, this heater is equipped with a manual
reset high-limit switch and an air proving switch.
Never operate this heater with any safety device that
has been bypassed. Do not operate this heater
unless all of these features are fully functioning.
6.
Do not operate the heater with its door open or panel
removed.
7.
Do not locate fuel gas containers or fuel supply
hoses within 20 ft. of the blower outlet of the heater.
8.
Do not block air intakes or discharge outlets of the
appliance. Doing so may cause improper combustion
or damage to heater components leading to property
damage or animal loss.
9.
The hose assembly shall be visually inspected on an
annual basis. If it is evident there is excessive
abrasion or wear, or if the hose is cut, it must be
replaced prior to the heater being put into operation.
The hose assembly shall be protected from animals,
building materials, and contact with hot surfaces
during use. The hose assembly shall be that
specified by the manufacturer. See parts list.
10.
Check for gas leaks and proper function upon heater
installation, before building repopulation or when
relocating.

hazard and must be plugged directly into a properly
grounded three-prong receptacle. Failure to use a
properly grounded receptacle can result in electrical
shock, personal injury, or death.
14.
Direct ignition heaters will make up to three trials for
ignition. If ignition is not achieved, the control system
will lock out the gas control valve. If gas is smelled
after system lock out has occurred, immediately close
all fuel supply valves. Do not relight until you are sure
that all gas that may have accumulated has cleared
away. In any event, do not relight for at least 5
minutes.
15.
In a hanging type installation, rigid pipe or copper
tubing coupled directly to the heater may cause gas
leaks during movement, and therefore must not be
used. Use only gas hose assemblies that are rated
and approved for L.P.gas and natural gas in a hanging
type of installation.
16.
Installations not using the gas hose supplied with
this appliance must connect dimensionally using
American National Standard Wrought Steel and
Wrought Iron Pipe B36/10-1970. (Aluminum piping
or tubing shall not be used.) Copper tubing when
