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
