11.2 PRESSURE CHECK
Check Pressure Readings:
Inlet pressure can be checked by turning screw (A) counter-clockwise 2 or 3
turns and then placing pressure gauge tubing over the test point. Gauge should
readas described on the chart below. Check with main burner operating on
“HI”.
Outlet pressure can be checked the same as above using screw (B). Gauge
should readas described on the chart below. Check with main burner operating
on “HI”.
AFTER TAKING PRESSURE READINGS, BE SURE TO TURN SCREWS CLOCKWISE FIRMLY TO RESEAL.
DO NOT OVERTORQUE.
Leak test with a soap and water solution.
Prior to pilot adjustment, ensure that the pilot
assembly has not been painted. If overspray or
painting of the pilot assembly has occurred
remove the paint from the pilot assembly, or replace. Fine emery cloth or sandpaper can be used to remove
the paint from the pilot hood, electrode and
fl
ame sensor.

11.3 RESTRICTING VERTICAL VENTS
77.3
Vertical installations may display a very active
fl
ame. If this appearance is not desirable, the vent exit must
be restricted using a restrictor vent kit. Refer to “ACCESORIES” in the “REPLACEMENTS” section for the
appropriate kit. This will reduce the velocity of the exhaust gases, slowing down the
fl
ame pattern and creating
a more traditional gentle
fl
ame appearance. Speci
fi
c instructions are included with the kit.
