3. Plug power cord of heater into a three-prong,
grounded extension cord. Extension cord must
be at least six feet long. Extension cord must
be UL listed.
Extension Cord Size Requirement
Up to 50 feet (15 m) long, use 18 AWG rated
cord.
51 to 100 feet (15.5 to 30.5 m) long, use 16
AWG rated cord.
101 to 200 feet (30.78 to 61 m) long, use 14
AWG rated cord.
4. Plug extension cord into a 120 volt/60 hertz,
three-hole, grounded outlet.
5. Open propane supply valve on propane tank(s)
slowly.
Note:
If not opened slowly, excess-flow check
valve on propane tank may stop gas flow. If
this happens, close propane supply valve and
open again slowly.
6. Turn thermostat control knob fully coun-
terclockwise to the “cooler” position. Turn
thermostat control knob slowly clockwise
until electric motor and fan begin to run.
Heater will start in approximately 3 seconds.
Adjust thermostat control knob to warmer or
cooler setting as needed. To control the heat
output, adjust the gas valve to the desired
temperature.
Note:
If heater does not start after 3 seconds,
the ignition control will automatically attempt
to start heater one time. If heater fails to start
on this attempt, the safety control will "lock
out" and no further automatic restarts will be
attempted. This could occur if air remains in
fuel line. If heater fails to start on this attempt,
turn thermostat knob to the “cooler” position
until the motor stops turning. Wait ten seconds
for safety control to reset, then turn control
knob to the “warmer” position and try to start
heater again.

Thermostat Operation Only:
During normal
thermostat operation, heater will cycle off
when air temperature rises to thermostat set-
ting. When air temperature drops sufficiently
below thermostat setting, the electric motor
and fan will begin to run. After 15 to 60
seconds, heater burner should automatically
ignite and provide heat to maintain tempera-
ture setting.
OPERATION

TO STOP HEATER
1. Tightly close propane supply valve on propane
tank(s).
2. Wait a few seconds. Heater will burn gas left
in supply hoses.
3. Turn thermostat knob fully counterclockwise
to the “cooler” position.
4. Unplug heater.
STORAGE
CAUTION: Disconnect heater
from propane supply tank(s).
1. Store propane tank(s) in safe manner. See
Chapter 5 of
Standard for Storage and Han-
dling of Liquefied Petroleum Gases, ANSI/
NFPA 58
and/or
CAN/CGA B149.2
. Follow
all local codes.
2. Place plastic cover caps over brass fittings on
inlet connector and hose/regulator assembly.
3. Store in dry, clean and safe place. Do not
store hose/regulator assembly inside heater
combustion chamber.
4. When taking heater out of storage, always
check inside of heater. Insects and small
animals may place foreign objects in heater.
Keep inside of heater free from combustible
and foreign objects.
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.
