Maintenance Instructions

Before Each Use:

1. Check to make sure the heater's surrounding area
is kept clear and free from combustible materials,
gasoline, and other flammable vapors and liquids.
2. Regulators must be periodically inspected to make
sure the regulator vents are not blocked. Debris,
insects, insect nests, snow, or ice on a regulator
can block vents and cause excess pressure at the
appliance.
3. Check all hose and tubing assemblies for cracks,
cuts, abrasions or ruptures. Replace any hoses that
are suspect.
4. Check all gasketing on burner box and fan housing
discharge. Ensure all is in good condition. Replace
any gasket material if suspect

plates, etc. If any are lost or become hard to
read, replace them immediately. Do not operate
the heater until you have all instructions and can

Annually:
1. Check the air inlet assembly. Ensure the air inlet
assembly and its duct are free of blockages.

leaks or restrictions in gas lines. Also, at this time
have your gas supplier clean out the sediment
trap at the inlet of the burner box of any debris
that may have accumulated.
3. Regulators can wear out and function improperly.
Have your gas supplier check the date codes
on all regulators installed and check delivery
