MAINTENANCE AND STORAGE
Continued
11.Spiders and insects can nest and live in outdoor appliances, especially in the burners and orifices. This will interrupt the normal flow of LP gas to the heater and can be a very dangerous situation. Inspect for insect infiltration of burner/orifice when one of the following occurs:
A. The smell of gas along with predominating yellow tipping of the burner flames.
B. Heater can not reach desired temperature. C. Uneven burner flow.
D. Burner makes popping noises during normal use or shutdown.
12.When heater to be stored outdoors, detach connection between LP cylinder and heater. Remove cylinder from heater and store in accordance with chapter 5 of the standard for Storage and Handling of liquified gas.
13.Adopt rainproof cover (provided with the heater) to avoid rust of heater when not in use.
WARNING: Local codes for installation of propane systems may vary considerably. Therefore, ask your local propane supplier for advice on propane system installation. In the absence of local codes, install in accordance with Standard for the Storage and
Handling of Liquified Petroleum Gases ANSI/NFPA
GENERAL INFORMATION
During use, liquid propane in a cylinder vaporizes. As it vaporizes, the propane cools itself. If this cooling process lasts too long and proceeds too fast, the propane temperature and pressure will fall so low that the heater operation may be improper or even halt. Often frost forming on the outside of the propane container warns excessive refrigeration.
Recommendations on how to reduce refrigeration:
A. Provide considerably more propane than you plan
to consume, it’s better to provide twice as much.
B. Fill containers frequently, especially in cold weather. Never allow propane to fall below
CLEANING AND MAINTENANCE
CAUTION: You must keep control areas and top panel of heater clean. Inspect these areas of heater before each use. Have heater inspected yearly by a qualified service person.
WARNING: Shut off heater and let cool before servicing.
PILOT AND BURNER:
Clean dust with a vacuum cleaner.
BURNER AIR INLET HOLE:
We recommend that you clean the unit every three months or after 2500 hours operation. We also recommend that you keep the burner tube and pilot assembly clean and free of dust. To clean these parts, we suggest using compressed air no greater than 30 PSI. You can also use a vacuum cleaner in the blow position. If using compressed air in a can, please follow the directions on the can. Otherwise, you might damage the pilot assembly.
1.Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes.
2.Inspect burner, pilot, and primary air inlet holes on injector holder for dust and dirt. (See FIG.13)
3.Blow air through the ports/slots and holes in the burner.
4.Check the injector holder again, remove any large particles of dust and dirt with a soft cloth or vacuum cleaner nozzle.
5.Blow air into the primary air holes on the injector holder.
6.In case large clumps of dust have been pushed into the burner, repeat steps 3 and 4.
Clean the pilot assembly also. A yellow tip on the pilot indicates dust and dirt in the pilot assembly.

EXTERIOR:
Use a soft cloth dampened with a mild soap and water mixture. Wipe the cabinet to remove dust.
LOGS:
If you remove logs for cleaning, refer to installing logs, Pages 3 and 4 to properly replace logs. Replace logs if broken or chipped.
MAIN BURNER:
Periodically check all burner flame holes with the heater running. All slotted burner flame holes should be open with a yellow flame present. Some burner flame holes may become blocked by debris or rust, with no flame present. If so, turn off heater and let cool. Either remove blockage or replace burner.
Blocked burner flame holes will create soot.
