Pilot Lighting Instructions
1. The in-line service shut-o valve should be in the “ON”
position.
2. With a lighted taper light the pilots which are located at
the rear of the main burner.
3. The pilot ame should be approximately 7/8”
(22 mm) long for proper ignition of the burners. The
pilot adjustment valve is located by sliding the drip
tray forward. The adjustment valves are located on the
manifold pipe, which runs horizontally across the back of
the unit, behind the drip tray, one is at the left rear and
the other is at the right rear.
4. To adjust the pilot light, turn the brass screw counter-
clockwise to increase the pilot ame, and clockwise to
decrease the ame.
NOTE: No more than 7/8” (22 mm) pilot ame length should
be required. Too high a setting will cause the ame to lift o
or will create excessive carboning. Do not adjust the pilot
ame lower than 7/8” (22mm) long because this can cause
delayed ignition at the burner. The delayed ignition could
cause the burner tiles to crack, in that case the burner would
have to be replaced.
Main Burner Operation
1. Turn the main burner to the “MAX” position.
2. Immediately check ignition of the burner.
CAUTION: Should ignition fail after ve (5) seconds, turn the
valve o and wait ve (5) minutes before trying again. The
pilot gas is not interrupted automatically, it is the responsibility
of the operator to check the ignition of the burners
immediately after the burner valve has been turned on.
