11. MAINTENANCE INSTRUCTIONS
At least once a year, a qualified service agency needs to be contracted for other than routine maintenance,
including such things as checking the burner head and checking combustion.
WARNING: Turn off all electrical service to the appliance when accessing the limit or other controls
located inside the appliance or burner control cabinet. This cabinet contains High Voltage wiring and
terminals. Close and fasten the control cabinet cover before restoring electrical service to the
appliance. If the electrical service is not turned off and these terminals are touched, a dangerous
shock causing personal injury or loss of life could occur.
Caution: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and
dangerous operation. Verify proper operation after servicing.
Attention. Au moment de l'entretien des commandes, étiquetez tous les fils avant de les débrancher. Des
erreurs de câblage peuvent entraîner un fonctionnement inadéquat et dangereux. S'assurer que l'appareil
fonctionne adéquatement une fois l'entretien terminé.
1. Keep the area around the conversion burner clear and free from combustible materials, gasoline, and
other flammable vapors and liquids.
2. The blower motor is the only moving part. It does not require lubrication, since the ball bearings have
been permanently lubricated.
3. The user should do periodic visual checks of the burner and the flame.
4. Check for obstruction of combustion air and ventilating air flow.
5. Periodically inspect and checkout the burner ignition, control system, and fuel valve operation (for tight
close-off).
6. Examine the venting system at least once each year for proper connections, alignment and corrosion.
7. The blower inlet will collect dust from the air during operation. Disconnect the power to the heater and
clean the blower wheel when necessary.
8. Inspect all parts and make replacements when necessary.
9. Check wiring for loose connections and burned wires.
