3.0 Installation of the Fireplace
3.1 Installation in Manufactured Homes
If the fireplace is to be installed in a manufactured
home, the following WARNING and
CAUTION
apply:
WARNING: Do not install in sleeping room.
CAUTION: The structural integrity of the
manufactured home floor, wall and
ceiling/roof must be maintained.
3.2 Preparations
Select wall location where all the minimum
distances, as shown in Table 2 can be met. Proceed
as follows. Numbers in ( ) are item numbers from
Table 1 and Figure 1.
Determine the height you want the firebox floor off
the finished grade. The legs (1) provided with the
kit are 18 inches tall and place the firebox about 24
inches above the finished grade. If this height is not
desirable, discard the legs and construct base from
concrete blocks.
Select a high temperature fire clay or refractory
cement and mix according to manufacturer’s
instructions.
Once the fireplace is constructed you must wait at
least 21 days before building a fire to give the
cement adequate time to cure.
3.3 Assembly of Components
A. When the base is level and square, set the
baseplate (2). Level it from side to side and
front to back.
B. As shown in Figure 1, install the four sidewall
pieces (3) and the back header (6). Use one-
half inch of mortar between each section.
Smooth out mortar and make sure sections
remain level.
C. After installation of the back header (6), Install
the firebrick inside the firebox. Line the floor,
then the back and then the sides
Apply ¼-inch
thick layer cement to the back of the brick, and
1/4 –inch mortar joint around the brick.
Note: Add extra cement to mixture when applying
brick and add water to thin mixture. The
cement should be richer and wetter when used
on firebrick.
