Commander Ductable Make-Up Air Heater
WARNING
Do not use a pressure washer, water, or liquid
cleaning solution on any gas controls. Use of a
pressure washer, water, or liquid cleaning solution on
the control components can cause severe personal
injury or property damage due to water and/or liquids:
■ In electrical components, and wires causing
electrical shock or equipment failure.
■ On gas control valves causing corrosion which can
result in gas leaks and fire or explosion from the
leak.
Clean all components of the heater with pressurized
air, a dry brush, or a dry cloth.

Maintenance Instructions

BEFORE EACH USE:
• Check the area surrounding the heater to ensure it is
clear and free of combustible materials, gasoline, and
other flammable vapors and liquids.
• Have your gas supplier check all gas connections for
leaks or restrictions in gas lines.
• Inspect the regulator vent to make sure the regulator
vent is not blocked. Debris, insects, insect nests,
snow, or ice on a regulator can block vents and cause
excess pressure at the heater.
• Check all wiring associated terminals and electrical
components within the heater for corrosion, frayed
or cut insulation, tight connections, etc. Repair or
replace as necessary.
• Check the hose assembly after heater installation,
relocation and when the heater is in use. 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 back into operation.
• The heater's fan wheel should be checked
periodically for damage and cleanliness.
