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
58-1995 and National Fuel Gas Code ANSI
Z223.1-1996. Your supplier, fire marshal or library
should have a copy. The propane used must be
arranged for vapor withdrawal. Propane cylinders
must be secured in the upright position to keep them
from falling or being knocked over.
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
one-third of container capacity.
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.
MAINTENANCE AND STORAGE
Continued
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.
