LIGHTING AND SHUT DOWN
Lighting the Heater
1 Before attempting to light the heater, smell all around
the heater area for gas. Be sure to smell next to the floor
because LP Gas is heavier than air and will settle on the
floor. Turn on the gas supply to the appliance and check
all fittings and connections for gas leaks using a mild
soap and water solution. NEVER use a match to check
for gas leaks. Should a gas leak occur, shut off the gas
supply to the appliance immediately. Wait a minimum of
five minutes before repairing the leak.
2 Use only the fuel intended for this appliance. Check the
appliance rating plate for the correct fuel information.
3 Depress knob then turn the gas valve knob clockwise to
the “OFF” position. See Fig. 1 and Fig. 2 for location of
appliance parts.
4 Wait a sufficient length of time (at least five minutes)
to allow gas which may have accumulated in burner
compartment to escape.
5 Turn on the main gas supply.
6a Depress and turn Control Knob counterclockwise to
“Pilot” position and hold for 1-2 minutes. This may take
longer to purge air from the supply hose depending on
the length of the hose being used.
Depress red spark ignition button to light pilot flame
(repeat until pilot lights) and continue to hold Control
Knob at “Pilot” positionfor 30-60 seconds to enable Pilot
Light Safety System.
Fully turn Control Knob to “ON” position to light burner.
or...
6b To light the pilot, move the lighting hole cover aside
(see Fig. 1) and place a lighted match into the hole.
Depress the gas valve knob and hold while lighting
and observing the pilot burner. Ensure that the pilot
burner ignites from the match. Allow the pilot to burn
approximately 30 seconds before releasing the gas valve
knob. If pilot does not remain lighted, repeat the lighting
operation allowing a longer period of time before
releasing the gas valve knob.
NOTE: In cases where long runs of gas supply lines have been
installed ahead of the appliance, it may be necessary to bleed
trapped air out of the supply lines before lighting the pilot.
New installations generally require bleed of supply lines. Wait
a minimum of five minutes after bleeding the supply lines
before attempting to light the heater.
Adjust pilot if necessary as noted under “Pilot Burner
Adjustment.”
7. Turn the gas valve knob counter-clockwise to the “ON”
position (see Fig. 1). The burner will light. Turn knob
clockwise until stop for low fire position.
8. IMPORTANT: DO NOT attempt to adjust the main
burner input beyond stop, for this may cause the pilot
and thermocouple to shut down the burner (Fig. 2).
Piping must be clean and free from scale or burrs.
Install regulator supplied with heater. Connect with 1/2” NPT
nipple (not included) to Control Valve.
Connect the appliance to an appropriately designed and
installed fuel supply system. This system must include an
approved manual shut-off valve which is readily accessible and
is located within six (6) feet of the appliance. Additionally, a
sediment trap or drip leg must be located upstream of this
manual shut-off valve. Refer to the appropriate (natural gas)
installation code noted above. If a flexible connector is used,
it must be of an approved type.
Before attempting to ignite the appliance, all gas fittings and
connections must be thoroughly checked for gas leaks. Apply a
small amount of a mild soap and water solution to all fittings and
connections and observe for escaping bubbles. If any leaks are
detected, shut off the gas supply to the appliance immediately.
Wait a minimum of five minutes, repair the leak(s) and retest for
leakage. Dry all fittings and connections after leak testing.
WARNING
NEVER USE A FLAME FOR GAS LEAK TESTING.

ATTENTION - CRITICAL POINTS TO
REMEMBER!
• Propane (LP) gas has a distinctive odor. Learn to
recognize these odors. (Reference Fuel Gas Odor and
Odor Fading sections above.
• Even If you are not property trained in the service and
repair of the heater, ALWAYS be consciously aware of
the odors of propane (LP) gas and natural gas.
• If you have not been properly trained in repair and
service of propane (LP) gas then do not attempt to
light heater, perform service or repairs, or make any
adjustments to the heater on the propane (LP) gas fuel
system.
