Operating Instructions and Owner’s Manual
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.”
8. Turn the gas valve knob counter-clockwise to the
“ON” position (see Fig. 1). The burner will light. DO
NOT operate the heater in any other than the full
“ON” position.
9. IMPORTANT: DO NOT attempt to adjust the main
burner input using the main gas supply valve, 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, 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 125-R, 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.
