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 the 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.

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).

Shut-down instructions:

To turn the heater OFF,
• For short periods of time, turn the main burner off by
rotating the gas valve knob clockwise to the "PILOT"
position.
• For extended periods of non use, depress knob, turn the
appliance completely off by rotating the gas valve knob
clockwise to the "PILOT" position, depress the knob
slightly, then rotate the knob fully clockwise to the "OFF"
position. (Note: For Model 120L, also turn off the gas
supply cylinder.)
Pilot burner adjustment:
1. Remove the pilot adjustment cap. The pilot adjustment
cap is a slotted screw located in front of the "Pilot"
designation stamped on top of valve body just below the
gas valve knob.
2. Adjust the pilot key to provide properly sized flame.
Rotate the key "clockwise" to decrease or "counter-
clockwise" to increase flame.
3. Replace the pilot adjustment cap.
