Heater Area
Keep the area near the heater clear and free from combustible
materials, gasoline and other flammable liquids and vapors.
Combustion and Ventilation Air
The combustion and ventilation air supply must not be blocked.
Do not put anything in or on the heater cabinet. For better circulation
and more effective heating, do not place obstructions, furniture or other
items closer than four feet to the front of the cabinet or two feet from
each side of the cabinet.
Annual Upkeep Needed
It is recommended that a qualified service technician perform these
checks at the beginning of each heating season.
Cleaning Blower (If Equipped)
Shut off electricity. Clean any lint or dirt from fan blades, fan motor and
exposed air passages. Annually put two drops of SAE 20 oil in each of
the two cups or oil tubes.
Pilot Burner
Light pilot using instructions in "OPERATING INSTRUCTIONS". Leave
thermostat at lowest setting. Pilot flame should surround 1/2 to 5/8
inches of the generator tip. If flame needs adjusting, do so as follows:
Adjust Pilot Burner
1. Remove screw cover over pilot adjusting screw.
2. Insert small screwdriver. Adjust flame as needed. Turn screw
counterclockwise to increase flame, clockwise
decrease.
3. Turn thermostat to highest setting. Main burner should light quickly
and smoothly. Turn thermostat to lowest setting. Main burner
should go out. Pilot should remain lit.

Burner Cleaning
Check burner. If cleaning is required, contact a qualified service
technician to clean and service burner.
Cleaning Burner Compartment
Because cold air is attracted to the flame during heater operation, a
build up of lint from carpeting, bedding, dust, etc. in the burner area will
occur. It is necessary to clean this area regularly. Use a vacuum
cleaner with a narrow attachment to reach small areas. Be careful in
and around the pilot. A change in its adjustment could be made if
moved during cleaning.
A build up of any dust, lint or foreign material in the primary air
opening of the burner can interfere with the proper air gas mixture
and can result in a yellow flame which can produce carbon monoxide
and soot. This condition if allowed to develop, can lead to bodily
injury including death. It is imperative that the burner be kept clean.
To Remove Logs from Combustion Chamber
Always remove the logs from the combustion chamber when cleaning
the burner or combustion chamber.
1. As parts are removed, place them in a safe place until ready for
reassembly.
2. Remove the chrome hearth assembly. Compression clips hold
hearth assembly in place. Grasp assembly frame and pull forward.
3. Remove the screws in the glass window frame.
IMPORTANT- The logs are made of special light weight materials that
can be easily damaged by rough handling.
4. Lift the front log up and out of the front log support brackets
carefully. Take care when pulling it out through the window
opening. Do not scrape it against the metal edges of the opening.
5. Remove the screws and plates holding the top right and top left
sides of the rear log set against the top rear support brackets.
6. Lift the rear log set up and out of the bottom support brackets. Tilt
the top towards the back and slowly allow the bottom to pass
through the opening first. Take care not to scrape it against the
metal edges of the opening.
7. Reverse the above procedure to reassemble after cleaning.

Glass Cleaning
Use mild soap and water only. Never clean when glass is hot.
If the glass is broken it must be replaced with the manufacturer's
authorized part only. Failure to do so could cause property damage,
bodily injury or death.
