Generally, flame appearance is a matter of
individual preference, however a warm yellowish
flame is most common.
Closingtheairshutter-inextremecasesmay
generate very long yellow flames resulting in soot.
Sooting produces black deposits on the logs, on the
inside walls of the appliance, and potentially on the
exterior termination cap.
Sooting is caused by incomplete combustion in the
flames and lack of combustion air entering the air
shutter opening.
Opening the air shutter - will generate a flame that
isblueandtransparent,or“anemic”.Thisflameis
generally more efficient, but not as attractive.

6.11 Operation Notes
1. For the first several hours of operation, it is common
to detect some odor as the metal and manufacturing
materials cure under heat. This condition is temporary
and can be alleviated by allowing plenty of fresh air to
circulate through the area.
