PROPANE CONSTRUCTION HEATER

MAINTENANCE

Repair should be done by a qualified service person. The appliance should be inspected before use and at least annually by a professional service person. more frequent cleaning may be required due to excessive debris. it is imperative that control compartments, burners and circulating air passageways of the heater be kept clean. dust, lint, cobwebs or debris may affect heater performance. The heater draws air into it during normal operation and in the process dust, lint or debris may be drawn into it. Before cleaning ensure the gas supply is turned off at the cylinder and the gas control knob is in the “off” position.

Pilot and Burning Inspection

each time you light the heater check that the pilot flame and burner flame patterns are as shown in fugures 4 and 5. if flame patterns are incorrect, turn the heater off and contact your dealer or qualified service person for assistance. do not operate the heater until the pilot and burner flames are correct.

note: do not mistake orange flames with yellow tipping. dirt or dust particles may enter the burner flames and cause transient patches of orange flame.
