Adjust the pilot screw to provide properly sized fl ame. Turn
in a clockwise direction to reduce the gas fl ow.
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 fl ame, but can lead to carboning. Opening the air
shutter will cause a more blue fl ame, but can cause fl ame
lifting from the burner ports. The fl ame may not appear yellow
immediately; allow 15 to 30 minutes for the fi nal fl ame colour
to be established.

This is a fast acting ther-
mocouple. It is an inte-
gral safety component.
Replace only with a fast
acting thermocouple sup-
plied by Wolf Steel Ltd.
Vertical installations may display a very active fl ame. 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 fl ame pat-
tern and creating a more traditional gentle appearance.
