SSTB11 Woodburning Fireplace
Location Selection
Unpack and check the fireplace and chimney for dam-
age. If any items have been damaged, report this to your
dealer. Before beginning the installation, be sure you
have the proper parts in sufficient quantity. Refer to re-
placement parts page for proper identification of parts.Do
not substitute parts. Use only parts listed for use with the
Model SSTB11 fireplace.

Fireplace Installation

1. Refer to Figure 1 for an example of a typical installa-
tion of the fireplace components.
2. Be sure the location of the fireplace will provide the
required clearances indicated by Figures 2, 3 & 5 and
the minimum chimney air space clearance to combus-
tibles of 2".
3. Set the fireplace in the desired location and be sure
it is securely supported and leveled. Check the face
of the fireplace with a carpenter's level and if it is not
plumb; correct it by placing shims under the edges of
the fireplace.
4. Block in the fireplace to prevent any shifting of the fire-
box. Secure the fireplace with nails or screws through
the flanges located on each side of the fireplace. Do
not enclose the fireplace until the combustion air duct
and chimney pipes are installed.
NOTE: Some local codes may require electrically ground-
ing the fireplace and chimney.

Chimney Installation

In order to assure safe and satisfactory performance of
the fireplace, it is very important to properly install the
chimney. This is an important part of the installation and
the sections of this manual pertaining to chimney installa-
tion should be reviewed very thoroughly.
For your safety, some of the important things to remem-
ber in regard to chimneys are listed below:
1. Use only parts and accessories labeled for use with
this fireplace.
2. Use only undamaged parts and accessories.
3. Enclose the chimney where it passes through the liv-
ing spaces to prevent contact with and possible dam-
age to the chimney.
4. Install firestop spacers at each ceiling level.
5. Install the proper chimney cap or chimney housing on
the chimney to prevent the entry of rain and debris
into the chimney and to assure the proper venting of
smoke.
6. Do not use more than four (4) elbows in the chimney.

FIREPLACE INSTALLATION
NOTE: To select the proper chimney height, refer to Fig-
ure 1. The flue outlet must be a minimum of 3' above the
highest point where the chimney penetrates the roof and
a minimum of 2' above all portions of the building within
10'. If the chimney is to include elbows to offset the chim-
ney, refer to the Chimney Offset and Cap Installation sec-
tion of this manual. There must be at least 2" air space
between all sections of the chimney and combustible ma-
terials between floors.

CHIMNEY INSTALLATION
1. Lay out, cut and frame openings through all ceilings
and the roof at the point where the chimney will pass
through. Unless the chimney is to be offset, the point
where the center line of the chimney will pass through
the ceiling and roof can be determined with a plumb
line as shown in Figure 12. The fireplace should be
located in the planned installation position. After the
center line is established and a nail is driven to mark
the point, the opening can be cut if you are satisfied
with the chimney location relative to ceiling and roof
joists and/or any other obstructions. The roof opening
center line should be marked by driving a nail through
the roof from underneath that will penetrate the roof
and can be located from the rooftop. If the chimney is
to penetrate a pitched roof, the hole in the roof must
be rectangular instead of square and should be sized
according to Table 1.
