Installation
Installing and Framing the Fireplace
The
B-Series-DV-2
fireplaces may be installed in any location that main-
tains proper clearances 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 5 - Vent
Installation for more information.
The fireplace dimensions are shown below:

* Clearance from the top of the fireplace to a combustible ceiling
within the fireplace enclosure.
** Refer to page 12,
(Mantels and Surrounds).
Unprotected combustible walls which are perpendicular to the fireplace
opening, must not project beyond the area shown in Figure 23.
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.
