10.0 ADJUSTMENT
10.1 RESTRICTING VERTICAL VENTS
Adjust the pilot screw to provide properly sized fl ame. Turn in a
clockwise direction to reduce the gas fl ow.
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 read 7” (minimum 4.5”) water
column for natural gas or 13” (11” minimum) water column for
propane. Check that main burner is operating on “HI”.
Outlet pressure can be checked the same as above using
screw (B). Gauge should read 3.5” water column for natural
gas or 10” water column for propane. Check that main burner
is 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.

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. Specifi c instructions are included with the kit.
