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
read 7" (minimum 4.5") water column for natural gas or 13" (11" minimum) water
column for propane. Check with main burner 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 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.

11.3 RESTRICTING VERTICAL VENTS

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.
