MANTEL CLEARANCE WITH HOOD
WARNING:
Be certain that combustible flooring material (i.e.; carpet, tile etc.) is not too close to this gas appliance. If this
appliance is at floor level or less than 6” above the floor, there must be at least 12” of noncombustible material
between the base of the fireplace and any combustible flooring.
A fireplace hood deflects heat away from the fireplace face and mantel, reducing the potential for heat related warping or discoloration.
The use of a fireplace hood is highly recommended.*
IF YOU CANNOT MEET THESE MINIMUM CLEARANCES YOU MUST OPERATE THE APPLIANCE AS A VENTED
APPLIANCE WITH CHIMNEY FLUE DAMPER OPEN. (See notes regarding vented installation on following page)

MINIMUM CLEARANCES TO SIDE WALL AND CEILING
Side wall: 15 1/2" from side of fireplace opening.
Ceiling: 42" from top of fireplace opening.
NOTE:
Clearances to Combustible Construction are those
distances required to ensure that a fireplace mantel or
facing will not catch fire. In most cases they should also
be adequate to prevent any discoloration or warping due
to heat. However, each and every decorative gas appli-
ance installation (CHILLBUSTER™ included) presents a
different and completely unique set of circumstances
involving many variables beyond the control of the manu-
facturer. These include paint or finish composition, previ-
ous exposure to heat, methods and quality of construc-
tion, air flow patterns, glass doors, fans or blowers, etc.
Because of these variables, we cannot guarantee that
heat warping or discoloration will never occur. The poten-
tial for heat warping or discoloration may exist whether
you are burning an CHILLBUSTER™, some other manu-
facturer's decorative gas appliance or even wood.
