Adjust the pilot screw to provide properly sized flame. Turn
in a clockwise direction to reduce the gas flow.
Natural gas models have air shutters set at 1/4 (.250") inch
open. Propane gas models have air shutters set at 7/16
(.437) inch open. Closing the air shutter will cause a more
yellow flame, but can lead to carboning. Opening the air
shutter will cause a more blue flame, but can cause flame
lifting from the burner ports. The flame may not appear
yellow immediately; allow 15 to 30 minutes for the final
flame colour to be established.

WARNING: This is a fast act-
ing thermocouple. It is an in-
tegral safety component.

Vertical installations may display a very active flame.If this
appearance is not desirable,the vent exit must be restricted
using the optional restrictor vent kit, RP40-KT. This will
reduce
the velocity of the exhaust gases,slowing down the flame
pattern and creating a more traditional gentle appearance.
Specific instructions are included with the kit.
