Selecting A Location - Majestic B36LA Installation, Operation And Maintenance Instructions

FIREPLACE LOCATION
CAUTION: Do not install fireplace over carpeting.
This fireplace does not require any special foundation. If the fireplace is to be trimmed with large stone or
brick facing, an adequate foundation is required to support these materials. Use Figures 5 and 6 as a guide
for selecting a location and determining the space required for the fireplace.
The location for the fireplace should be adjacent to the load bearing wall and away from objects that will
create drafts that could disturb the normal flow of air into the fire. Such objects are frequently opened doors
and central heat and air outlets and returns. Figure 4 illustrates various types of locations and installation
and Figure 1 gives additional information concerning installation heights, construction details, and methods
on installation.
A location that requires cutting the least number of joists and rafters for the chimney installation will simplify
and reduce installation cost. The opening required for passage of the chimney through the roof, ceilings and
floors must be 17 inches square as indicated by Figures 6, 7 and 8. The 17 inch square opening provides
for the installation of the model LF-FS-2 firestop spacer in a residential installation.
Since the pitch of the roof influences the opening size required at the roof level, table 1 should be used as
a guide for sizing the roof opening.
Proper selection of a chimney outlet location is also important. Objects such as overhanging or nearby
trees, adjacent building or embarkments or unusual roof designs can all create air turbulence and interfere
with chimney performance and cause the fireplace to spill smoke into the room.
A factory-built fireplace, properly installed in a single story wing of a multi-story building as shown in Figure
9, may be affected by environmental factors that will cause poor chimney draft and occasional spillage of
smoke from the fireplace opening. Although this occurs infrequently, location of the fireplace in the preferred
location as indicated by Figure 9 is recommended.
If the chimney is to pass through living areas or spaces used for storage, be sure that it will be possible to
enclose the chimney to prevent contact with and possible damage to the chimney. Elbows may be used to
avoid obstructions such as electrical wires, water, or sewer pipes, attic fans, heating ducts, etc. Refer to the
section of this manual concerning chimney offsets for proper elbow installation and use.
If the failure is to be installed in an outside wall, the surrounding walls should be enclosed and insulated.
Failure to properly enclose the fireplace will cause a heat loss and diminish the fireplace efficiency due to
transfer of heat through the fireplace to the outside.
