E. Air Shutter Setting
Air shutter setting should be adjusted by a qualified
installer at the time of installation.
•
The PHOENIX air shutter is set to its minimum opening
at the factory. A small amount of light soot on the logs is
normal, but soot should not build-up to form “nuggets”.
•
On units converted to burn propane, the air shutter
should be removed.
Note:
Adjust air shutter after flame has reached full
maturity (approximately 20-40 minutes).
CAUTION! Risk of Burns! Components are HOT. Wear
protective gloves when adjusting shutter.
