Glass Doors; Fireplace Finishes; Mantels And Trim; Hearth Extensions/Wall Shields - Superior BC36MH Installation Instructions Manual

Note: A 1" air space must be preserved for all
combustible materials extending for any con-
tinuous length adjacent to the chimney.
It is especially important to insulate between
the studs of an outside chase cavity and under
the floor if the floor is above ground level. Do
not place insulation directly against the fireplace
or chimney system.

glass doors

Glass doors have been installed on these
fireplaces as standard equipment. Shipping
and transit may have moved them out of
alignment.
The doors are properly adjusted when the top
door trim is in a straight, level line and the
gap between the doors is even at the top and
bottom. If adjustments are required, grasp the
door handle and loosen the lower door pivot pin
using a 3/8" open end wrench*. Slide the door
panel on the hinge pin until the gap between
the upper door trim and upper frame is even.
Retighten the lower door pivot pin*. Repeat
this procedure for the opposite door if needed
(Figure 40).

*Note: Upper door pivot pins can also be
loosened for adjustment purposes; however,
it is easier to loosen lower pins.

Mantels and trim

It is sometimes best to frame your fireplace after
it is positioned and the chimney is installed.
Frame enclosure for chimney and fireplace with
materials of suitable grade and size as dictated
by the prevailing constructions standards for
the structure in which the fireplace system is
to be located within.
Note: The header may rest on the two (2) metal
top spacers on top of the unit but the header must
not be notched to fit around the spacers.

These fireplaces may sit directly on a com-
bustible surface. A 1"** air space is required
between framing, insulation, building materials
and the chimney. A 1" air space is required
between framing, insulation, building materials
and the fireplace outer wrapper. In Canada, the
minimum height for a combustible mantel is 18"
(457 mm) above the fireplace opening. Figure
41A shows typical Canadian installations.
Combustible mantels and trim may be installed
12" above the fireplace opening as per NFPA
211-latest edition, and Figure 41. If a mantel
is of a noncombustible material, it is exempt
from these requirements as long as it does not
encroach on the fireplace opening or circulat-
ing air in or out.

hearth Extensions and Wall shields
A hearth extension must be installed with all
fireplaces. Its purpose is twofold. It protects a
combustible floor in front of the fireplace from
both radiant heat and sparks and it distinguishes
the prescribed hearth extension area from other
non-protected surfaces.
The hearth extension must extend 16" beyond
the front and 8" beyond both sides of the fireplace
opening. Use a hearth extension constructed
of a durable noncombustible material having
an equal or better (lower k value) insulating
value of k = .84 BTU IN/FT HR °F or a thermal
2
resistance that equals or exceeds r=1.19 HR
°F FT /BTU IN. A minimum 3/8" (10 mm) thick
2
noncombustible material is all that is required
over a noncombustible or slab floor.
If there is a continuous perpendicular side wall
closer than 12" (305 mm) from the fireplace
opening, it must be protected with a 24" x 30"
(610 mm x 762 mm) wall shield (see Figure
42) constructed of a durable, noncombustible
material having an equal or better (lower k
value) insulating value than k = .84 BTU IN/FT
HR °F. A continuous protected side wall can
not be closer than 7" (178 mm) from the side
of the fireplace opening.
Secure the hearth extension to the floor to
prevent possible shifting.
If the fireplace is installed on a combustible
floor, use the metal safety strips (provided)
on the floor extending half under the fireplace
and half under the hearth extension (refer to
Figures 6 and 7).
