MAINTENANCE
WARNING: Never service
heater while it is plugged in,
connected to propane supply,
operating or hot. Severe burns
and electrical shock can occur.
1. Keep heater clean. Clean heater annually or
as needed to remove dust and debris. If heater
is dirty or dusty, clean heater with a damp
cloth.
2. Inspect heater before each use. Check connec-
tions for leaks. Apply mixture of liquid soap
and water to connections. Bubbles forming
show a leak. Correct all leaks at once.
3. Inspect hose/regulator assembly before each
use. If hose is highly worn or cut, replace.
4. Have heater inspected yearly by a qualified
service agency.
5. Keep inside of heater free from combustible
and foreign objects.
5. Open propane/LP supply valve on propane/LP
tank(s) slowly. Note: If not opened slowly, ex-
cess-flow check valve on propane/LP tank will
stop gas flow. If this happens, you may hear a
click inside the regulator assembly. To reset
the excess flow check valve, close propane/LP
supply valve and open again slowly.
6. Make sure regulator is set between 7 and 20
psig. Note: Higher regulator setting will allow
heater to produce more heat.
7. Turn on/off switch to the ON position. Adjust
thermostat to desired setting. If heater does
not start, thermostat setting may be too low.
Turn thermostat knob to higher position to start
heater. Note: If heater does not start, turn on/off
switch to the OFF position. Wait ten seconds
for safety control to reset, then try again.

1. Tightly close propane/LP supply valve on
propane tank(s).
2. Wait a few seconds. Heater will burn gas left

3. Turn on/off switch to the OFF position.
4. Unplug heater.
TO RESTART HEATER
If safety control stops gas flow to heater, motor
will continue to run.
1. Turn on/off switch to the OFF position.
2. Wait ten seconds, then turn on/off switch to
the ON position.
If heater does not restart
1. Check manual valves (if any) and supply
valves (on propane/LP tank). Make sure they
