mounted in the horizontal position with the arrow
pointing in the direction of gas flow. See GAS
PRESSURE REGULATOR under REMOVAL AND
REPLACEMENT OF PARTS.
See data plate for manifold pressure setting
information. Clean vent cap [1] Fig. 28 before
adjusting.

1.
Connect manometer to measure gas manifold
pressure.
A.
Install a tee with hose barb connection on
the outlet side of the regulator. See
TOOLS. Connect the opposite end of tee to
the incoming gas supply for the machine.
2.
Turn gas supply on and light all pilots on the
machine.
3.
Open all valves to the full on position to light
burners and check manometer reading. The
reading should be 6" W.C. for natural gas and 10"
W.C. for propane gas. Tolerance is ±0.3" W.C.
4.
If manifold pressure is not correct, adjust the
regulator as follows.
A.
Remove the regulator closing nut [1] Fig.
29.
Fig. 29
B.
Insert a flat edge screwdriver through the
top of the regulator. While watching the
manometer, turn the adjusting screw
clockwise to increase pressure and
counterclockwise to decrease pressure until
the proper gas pressure is achieved.
C.
Install the regulator closing nut.
D.
Turn gas supply off.
E.
Remove manometer and tee from gas line.
Clean pipe threads and apply thread
sealant that is suitable for use with propane gases.
F.
Apply thread sealant to gas line pipe threads
and re-install regulator.
INFRARED BURNER ADJUSTMENT
The only adjustment for the Infrared burner is the gas
manifold pressure. Verify the pressure is set correctly
as outlined under REGULATOR ADJUSTMENT.
INFRARED BURNER FLAME
APPEARANCE
When the Infrared burner first lights you should see a
small rolling blue flame, which will clear up after the
burner warms. Once warm, a low profile orange flame
is the best description of the Infrared burner flame. In
some cases, if the burner is operating correctly, you
may not be able to see the actual flame. Instead you
will see the glow of the ceramic bricks in the burner.
GAS ORIFICE CHECK
If burner operation seems poor and other systems
have been checked, remove MANIFOLD COVER to
access the gas and air inlet for the Ceramic-Radiant
