ENDURANCE SERIES GAS RANGES - REMOVAL AND REPLACEMENT OF PARTS

SERVICE PROCEDURES AND ADJUSTMENTS

WARNING: CERTAIN PROCEDURES IN THIS SECTION REQUIRE ELECTRICAL TEST OR MEASURE-
MENTS WHILE POWER IS APPLIED TO THE MACHINE. EXERCISE EXTREME CAUTION AT ALL
TIMES. IF TEST POINTS ARE NOT EASILY ACCESSIBLE, DISCONNECT POWER AND FOLLOW
LOCKOUT / TAGOUT PROCEDURES, ATTACH TEST EQUIPMENT AND REAPPLY POWER TO TEST.

PILOT FLAME HEIGHT

Top Burners

To adjust the pilot flame height of the top burners,
locate the pilot adjustment screws found on the front
manifold pipe. It is not necessary to remove the
manifold cover as adjustment access holes have
been provided in the panel.
1. Locate the pilot adjustment screw located
behind the adjustment access hole in the panel.
2. Rotate the screw clockwise to decrease and
counterclockwise to increase the flame height.

Broiler/Griddle

To adjust pilot flame height of broiler/griddle, locate
the pilot adjustment screws found on the broiler/
griddle manifold pipe. It is not necessary to remove
the manifold cover, as adjustment access holes have
been provided in the panel.
1. Locate the pilot adjustment screw located
behind the adjustment access hole in the panel.
2. Rotate the screw clockwise to decrease and
counterclockwise to increase the flame height.

AIR SHUTTER ADJUSTMENT

The efficiency of the oven depends on a delicate
balance between the air supply and the volume of
gas. Whenever this balance is disturbed, poor
operating characteristics and excessive gas con-
sumption will occur. An air shutter on the front of the
oven burner controls the gas mixer balance. A yellow
streaming flame on the burner is an indication of
insufficient air. To correct this condition, rotate the air
shutter open until the burner flame begins to lift from
the burner, then close the shutter slightly.

OVEN BURNER ADJUSTMENT

All Endurance Range series units equipped with a
pressure regulator and fixed orifices have been
adjusted at the factory and should require no further
adjustments. However, the efficiency of the range
depends on a delicate balance between the air
supply and the volume of gas. Whenever this
balance is disturbed, poor operating characteristics
and excessive gas consumption will occur. An air
shutter on the front of the oven burner controls the
gas mixer balance.
