rules for safe installation
1. Read the Owner's Manual and the Rules for Safe
Operation carefully. Failure to follow these rules
and the instructions could cause a malfunction of
};
9. The metal components of the fireplace and
chimney may have sharp edges or protrusions
which can cut easily. Be extremely careful to
avoid personal injury.
10. Check for wires above house and near chimney
area. Allow plenty of clearance. Do not touch any
wires. Fatal electric shock could result.
11. The fireplace must be connected to a 120 V AC
Electrical Circuit to operate properly. The unit
must be electrically grounded in accordance with
the National Electrical Code, ANSI C1.1975 when
Installed.
12. For your safety and protection, chimney should'be
grounded through fireplace. If they are not, use a
ground rod, clomp and wire, to ground chimney
and unit.
13. Provide air for combustion from the outside into
the room where the fireplace is located. If the
intake is not in the some room, the air must have
free access to the room, or install the Outside Air
Kit 42.8475.
14, Before servicing, allow fireplace to cool. Always
shut off any electricity and gas (if gas is used) to
fireplace when working on it. This will prevent
any electrical shocks or burns.
15. Keep glass doors and fire screen closed at all
times except when adding fuel.
16. Keep outlet flue damper fully open at all times
while heat is present in fireplace.
assembling and locating your fireplace
Remove all parts and check against list below:
1 Fireplace (assembled)
1 Upper Chimney Connector
1 Lower Chimney Connector
1 Collar
Plus any other optional equipment you have or-
dered.
Report to Sears if any parts are missing or
damaged.
Your fireplace is shipped completely assembled
with two sections of porcelainized flue shields and
two lengths of stainless steel flue pipe. It may be
installed in any room with ceiling height up to 9 feet.
For installation in rooms with higher than 9 foot
ceilings, additional lengths of shield and pipe may be
used. See Page 14. If it is to be installed in a Mobile or
Modular Home, prefabricated chimney must ter-
minate with Mobile Home Round Top. See Page 8 for
installation instructions.
Locating Your Fireplace
Refer to Figs. 1, 2, and 3 for clearances which must
be observed for safe operation of the fireplace. If
floor is combustible, a non-combustible base (2" patio
masonry block is recommended) must be used. Set
non-combustible base so it completely covers the area
under the fireplace and extends a minimum of 16" in
front of fireplace and 8" from each side of the
opening. Fireplace must be at least 7" from com-
bustible wall at sides on wall installation, If installed
in corner, 3" clearance from sides to combustible
material.
If qn Outside Air Kit 42 -8475 is to be installed,
arrangements for a 61/4" round hole must be made
thru the non - combustible base. This opening is
directly in line with the fireplace flue center line.
IMPORTANT: For your safety and protection, the
fireplace and chimney should be grounded. Use a
ground rod, clamp and wire to ground fireplace and
chimney.

installation instructions
Model 155.847400 Fireplace with 42-8475
Combustion Air Kit
To install 42 -8475 Combustion Air Kit on fireplace,
follow the instructions contained with kit.
Combustion Air Inlet
There is a 6" round combustion air inlet on the
bottom of the 42 -8475 Outside Air Kit, (Air Intake Base
Shield). When installed on the 155.847400 Fireplace,
this inlet is exactly in line with the top flue outlet.
Ref or. to Page 4 for dimensions of outlet. A damper is
installed in this inlet, It is controlled by a knob on the
front of the base. A 6" dia. telescoping inlet pipe is
supplied to duct outside air to the fireplace. The
opening for this pipe can be downward under the
fireplace (Fig. 22) if the air is to be taken from under
the floor. If the opening to the outside is at the rear
wall, the pipe can be elbowed, (Fig. 23). DO NOT
TAKE COMBUSTION AIR FROM ATTIC SPACE OR ANY
OTHER ROOM. If using the pipe directly on the
fireplace, place the cutout over an obstruction, such
as duct, joist, frame etc., the combustion air may be
token from outside by using a 10" x 3 -1/2" flat duct
from below the fireplace and above the floor thru the
outside wall. (Fig. 24.)
If the telescoping pipe is not long enough to extend
to the outside, (it expands from 15" to 34 ") it can be
extended with any 6" dia. galvanized pipe.
To install:
1. Locate the outlet and cut a 6-1/4" dia. hole for the
combustion air duct. Be sure to extend the 6 -1/4"
openings all the way through to the outside air
source. They must be thru any insulation vapor
barrier or sheet metal to the under side of home
(or outside if horizontal).
2. If Mobile Home: Position support box in ceiling
cutout and fasten securely to ceiling. On a flat
roof, it may extend above roof. If so, trim support
box above the roof as required to allow flashing
to fit flush on the roof. 1 inch clearance to Triple
Wall Pipe is required in attic (or other) space
above. Follow installation instructions on in-
stalling Sears Chimney. If Residential: Follow
installation instructions included with Sears
Residential Chimney.
3. Secure fireplace to non - combustible base with
screws provided thru holes on the inside edge of
the base.
IMPORTANT: For your safety and protection, the
fireplace and chimney should be grounded. Use a
ground rod, clamp and wire to ground fireplace
and chimney.
4. Secure combustion air pipe to fireplace. Push pipe
(with screen grill) through wall or floor from the
outside and secure to other pipe. Attach intake
grill to floor or wall with screws. If installed
through the wall, a decorative louver may be
mounted over the inlet to improve the ap-
pearance.
