FINISHING
Diagram 2
Diagram 1
IMPORTANT FINISHING DETAIL NOTE:
Before placing unit into final position - it is important to know the total
thickness / height of finished hearth (tile, carpet, etc.) The base of the
fireplace should be level or higher than the finished hearth height.
Diagram 3
Finishing material - thicker
than 1-1/4"
Diagram 4
Full Screen
Door
Important:
Finishing materials such as tile, river rock, etc, must not protrude
beyond the front facing flanges the sides and top of the firebox
opening.
Full Screen Doors Only:
If finishing with any material thicker than 1-1/4" - a 3/4" gap must
be maintained between the full screen doors and the finishing
material.
This gap is necessary to facilitate the installation and removal of
the full screen doors.
Note: All facing material should butt up cleanly to the flanges
around the firebox opening.
Rough edges will be visible from the front view with the flush
louvers or flush panels - if not using the finishing trim.
To maintain a clean finished edge - it is recommended to install
the drywall or other facing material with the finished edge against
the fireplace / nailing strips.
Alternatively, you can use J Style Trim or Metal Corner Bead
to cover cut edges of the facing material.

Note: There is a 1" air space between the unit and full screen door
which must not be covered.

BEFORE YOU START
The Top Facing Support, the Side Nailing Strips, the 2 Top Standoffs and the Flue Collar must be correctly positioned and attached before the fireplace
is moved into position.
TOP STANDOFF ASSEMBLY
The top standoffs are shipped in a flat position and must be folded into shape and
attached.
1) Remove the standoffs from the fireplace top.
2) Take each standoff and bend into the correct shape. Bend up at the bend lines until
the screw holes in the standoff and the pre-punched screw holes on the fireplace
top line up.
3) Attach the standoff securely to the top with 2 screws per standoff (on opposite
corners).
TOP FACING SUPPORT
Determine the total thickness of facing material (e.g. drywall or wood plus ceramic tiles) to
allow the finished surface to be flush with the front of the unit. Total facing thickness can vary
from 1/2" (13mm) to 1-1/4" (32mm) thick.
The Top Facing Support can be mounted in
3 different positions depending on the
thickness of the facing material.
1) Mount Top Facing Support using the 3 supplied screws into the three pre-punched
screw holes on the top front of the unit. Use hole positions A, B, or C depending on your
facing depth.

VENTING
INTRODUCTION
The B36X uses the "balanced flue" technology Co-Axial system.
The inner liner vents products of combustion to the outside while the
outer liner draws outside combustion air into the combustion chamber
thereby eliminating the need to use heated room air for combustion
and losing warm room air up the chimney.
Note: These flue pipes must not be connected to any other
appliance.
The gas appliance and vent system must be vented directly to the
outside of the building, and never be attached to a chimney serving
a separate solid fuel or gas burning appliance. Each direct vent gas
appliance must use it's own separate vent system. Common vent
systems are prohibited.
