Burn-in Period
The first few times this fireplace is operated, there will be an odor from the curing of paint and the burning off of the
lubricants used in the manufacturing process. Depending on usage, the burn-in period may take a few hours or a few
days.
NOTE:
Ventilate the site during the burn-in period. The resulting odor and haze may set off a smoke detector. Do not
operate the blower during the burn-in period.
A white film may develop on the glass front during the first few fires as part of the burn-in period. The glass
should be kept clean during the burn-in period to prevent the film from baking on—making it very difficult to
remove (
