Installation
Installing the Fireplace Shell
The fireplace may be installed in any location that maintains 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 the venting installation. Refer to page 4 -
Vent Installation
for more information.

models are shown below:

Clearances
The clearances to combustible materials are:
* Clearance from the top of the fireplace to a combustible
ceiling within the fireplace enclosure.
** Refer to page 14.

Figure 2.
Framing dimensions.
(Minimum 1" clearance must still be maintained around the vent pipes, except on
horizontal venting sections where the top of the pipe must have a clearance of 2")
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.
Framing
1.) Frame the fireplace cavity (thru-wall design) according to
Figure 2
.
2.) Frame your installation,
Figure 2a
if the design incorporates a shelf over the
fireplace.
3.) Once complete, slide the fireplace into the completed cavity.
4.) Next, tack four jack studs (vertical, "broken line") in place,
Figure 2c.
5.) Secure the fireplace in position by nailing/screwing the fireplace flange into
these jack studs.
