INSTALLATION INSTRUCTIONS
In planning the installation for the fireplace it is necessary to determine where the unit
is to be installed, the routing of the B-type vent system, and whether optional acces-
sories are to be used gas supply piping should also be planned.
Model SF4224-TV (with the use of the Outside Air Kit) can be installed in a bedroom
(in the United States) which has a total volume of unconfined space appropriate to
the particular installation. Refer to the National Fuel Gas Code ANSI Z223.1/NFPA 54
- (current edition), the Uniform Mechanical Code - (current edition), and Local Build-
ing Officials for the options allowed in obtaining an effective bedroom volume of
unconfined space.
The fireplace can be mounted on any of the following surfaces:
1. A flat combustible surface.
2. A raised wooden platform.
3. Four (4) corner supports.
(Example: four (4) concrete masonry blocks.) These supports must be positioned so
they contact all four corner edges on the bottom of the unit.
If the fireplace is installed directly on carpeting, tile, or other combustible material
other than wood flooring, the appliance shall be installed on a metal or wood panel
extending the full width and depth of the unit.
Fireplace framing can be built before or after the fireplace is set in place. Framing
should be positioned to accommodate wall covering and fireplace facing material.
The fireplace framing should be constructed of 2 x 4 lumber or heavier. The framing
headers may rest on the fireplace standoffs. Refer to Figure 7.1 for fireplace and
framing reference dimensions.
CAUTION: VERIFY FIREPLACE DIMENSIONS, FRAMING METHODS AND WALL
COVERING DETAILS BEFORE FRAMING CONSTRUCTION BEGINS.
Determine the exact position of the fireplace so that the vent run can be planned.
Figure 2.1 shows possible locations for the fireplace; inside of a room, flush mount in
a chase, or installed in a corner. Using a level, make sure the fireplace is properly
positioned and squared.
WARNING: DUE TO HIGH TEMPERATURES, THE APPLIANCE SHOULD BE
LOCATED OUT OF TRAFFIC AND AWAY FROM FURNITURE AND DRAPERIES.
CLOTHING OR OTHER FLAMMABLE MATERIAL SHOULD NOT BE PLACED ON
OR NEAR THE APPLIANCE.
Please note: B-Vent appliances are not designed to operate in negatively pressured
environments (pressure within the home is less than pressures outside). Significant negatively
pressured environments caused by weather, home design or other devices may impact the
operation of this appliance. Negative pressures my result in poor flame appearance, sooting,
damage to property and/or severe personal injury. Do not operate this appliance in negatively
pressured environments.
