Installing The Fireplace Shell
The fireplace may be installed in any location that maintains proper clear-
ances to air conditioning ducts, electrical wiring and plumbing. Safety,
as well as efficiency of operation, must be considered when selecting
the fireplace location. Try to select a location that does not interfere
with room traffic, has adequate ventilation, and offers an accessible
pathway for Direct Vent installation. Refer to page 4 - Vent Installation
for more information.

Clearances
Q

where the clearance to combustibles is 0". The H-Series BF clearances
O
to combustible materials are:

Flue
* Clearance from the top of the fireplace to a combustible ceiling within the fireplace
enclosure.
** Refer to page 11.
Unprotected combustible walls which are perpendicular to the fireplace
opening, must not project beyond the shaded area shown in Figure
25.
For protection against freezing temperatures, it is recommended that
outer walls of the chase be insulated with a vapor barrier. This will reduce
the possibility of a cold-air convection current on the fireplace.
