Range Top Components
The range top components consist of the following:
Maintop burner assembly (cooktop, burners, burner
caps and heads, igniter and switches, spark module,
manifold, and burner valves), thermal switches, and
door lock assembly.
Maintop Burner Alignment
For proper operation of the burner, alignment of
the orifi ce holder, orifi ce and air/gas mixer tube
must be correct. The alignment can be checked by
placing 7mm or 9/32” nutdriver over the orifi ce to
exaggerate the angle. The nutdriver should stand
straight, indicating the alignment and gas injection
angle are correct. A slight downward pressure may
be necessary to seat the nutdriver over the “Orifi ce
Retainer Ring.”
If an angle adjustment is necessary, remove the
burner cap, head and bowl to inspect the orifi ce
holder and the brackets that hold them in place.
Adjust as necessary. A misaligned burner may result
in uneven fl ames around the burner head.
Surface Burner Adjustments
Standard adjustments to the air shutter and gas
metering orifi ces are not possible on sealed burners.
If burner fl ames appear to be abnormal, check the
following:
• Check gas pressure available to the burners. The
required operating pressure is 5” W.C.P. (4" W.C.P.
for model PGS968) Natural Gas or 10” W.C.P. LP
(Propane) Gas. The pressure reading can be taken at
the BROIL, BAKE or TOP burner orifi ces.
• Check for drafts entering the burner box from
behind the range. Strong drafts beneath the
maintop can extinguish the burner and/or cause
erratic burner fl ames.
• Check for blockage or partial blockage of the
orifi ce. Inspect the orifi ce to be sure it has been
drilled on center and is free of debris or burrs.
• Check the burner alignment per the “Burner
Alignment” section of this manual.
• If the fl ames blow and lift off the burner and the
cause of the problem cannot be found, installing
an orifi ce with smaller diameter openings may
solve the problem. In a high altitude installation
(above 6000 ft.), the orifi ces will usually have to be
downsized.
Note: Refer to the Illustrated Parts Catolog for
specifi c issues of high altitude modifi cations when
needed.
