Lighting Instructions:

1. Bleed all air from piping leading to control.  Carefully re-tighten connection.
2. Turn CONTROL KNOB pointer to "OFF" position. Wait 5 minutes before lighting.
3. Turn CONTROL KNOB pointer to "PILOT" position.  Depress CONTROL KNOB and hold down 60 seconds after lighting pilot
burner. Release CONTROL KNOB. Pilot will remain lighted.
4. Turn CONTROL KNOB partially towards the "ON" position.  After gas fills burner pan medium, burner will light.  Dial may then be
turned to full "ON" or to desired flame height
5. If main or pilot burner extinguishes, turn CONTROL KNOB to "OFF" position.  Wait five minutes and repeat above lighting
procedure  from step 1.

clockwise to reduce size of pilot flame or counterclockwise
to increase flame.  Correctly adjusted pilot flame should be steady and soft blue
surrounding approximately 1/2 inch of thermocouple tip.  Never permit tip to exceed a
dull red temperature.

NOTE:  Ensure Right Front Log position does not allow burner flame to come in contact with Pilot
Assembly.  Direct burner flame on Pilot Assembly may will cause nuisance pilot shut-off or damage to pilot.

Burner Orifice

Burner Orifice:  

Burner Orifice is located at valve output fitting.

NOTE: Maximum flame height can be adjusted by changing orifice size, e.g., a
larger orifice results in a larger flame.

NOTE: Over sizing Propane Orifice may result in improper air mixing causing
excessive soot formation on the logs.
