ASSEMBLY OUTLINE
Before You Start
Check your inventcry list to
be sure you have all the
necessary parts supplieo in
good useable condition.
Check also for any concealed
damage.
Check the operation of the
flue damper. The flue damper
handle extends down from the
inside top of fireplace; push
in to close, puil out to open
-
takes firm pressure to lock
closed.
LOCATION OF
FIREPLACE
Carefully select the proper
location for heat circulation,
aesthetics, chimney obstruc-
tions, and clearance to side
wall. With proper prepianning,
a slight adjustment of a few
inches can save considerable
time
and expense during con-
struction and assembly.
If there is a perpendicular
;ide wall closer than 15" from
:he nearest side of the fire-
]lace opening, it must be pro.
ected with a metal vial1
jhield (WS4O), manufactured
by Superior or one con-
structed with a
40" x LO" x 1"
millboardor a durabls non-
combustible rnateriai ,with
equal or greater insulating
value (see
page 21).
ASSEMBLY STEPS
I. Position firebox prior to
framing or into prepared
framing.
2. Install chimney system
3. Install c?!ional cu:side
combustion air kit (required
for manufactured housing).
4. Field wire main power sup-
ply to fireplace
(if optional fan
assembly is to be installed at
a later time).
5. Complete finish wall mater-
ial, surround and hearth
extension to your own
individual taste.
6. Attach optional glass door
assembly (required for
manufactured housing).
Study the three dimensional
illustration (Figure 2) to get a
general idea of the location of
each element of your fireplace
system for conventional
homes. Refer to
(Figure 1) for
manufactured homes.
INSTALLING THE
FIREPLACE
The fireplace may be installed
directly on a combustible
floor or may be raised on a
platform of any desired
height. Do not place fireplace
on carpeting, vinyl or other
soft-surfacedfloor coverings.
It may, however, be placed on
flat wood, plywood, particle
board or other hard-surfaced
materials. Be sure fireplace
Haanh

rests on a solid continuous
floor or platform so no cold
air can enter room from under
fireplace.
The fireplace may be posi-
tioned and then the framing
built around it, or the framing
may be constructed and the
firepiace pushed into the
opening.
Usualiy, no special floor sup-
port isneeded for the fire-
place; however, to be certain:
1. Estimate the total weight
of the fireplace system and
surround materials such as
brick, stone, etc., to be
installed. Shipping weights for
the fireplace and chimney
components may be found in
the suggested price list.
2. Measure the square foot-
age of the floor space to be
occupied by the system, sur-
rounds and hearth extension

3. Note the floor construction
i.e. 2 x 6's. 2 x 8's or 2 x 10's.
single or double joists, type
and thickness of floor boards.
4. Use this information and
consult your local building
code to determine
if you need
,additional support.
CAUTION: DO NOT BLOCK
, THE HEAT CIRCULATING
AIR INLETS AND OUTLETS.
DOING SO MAY RESULT IN
A POTENTIAL FIRE
HAZARD.
.If you plan to raise the fire-
place and hearth extension,
build this platform assembly,
'then position fireplace and
;hearth extension on top.
TO INSTALL:
Step 1: Slide fireplace into the
prepared framing, or positlon
fireplace in its final location
for framing later.
.Step 2: Insert the metal hearth
'strips, packaged with your
fireplace beneath the fire-
place as illustrated

INSTALLING THE
CHIMNEY SYSTEM
Step 1: Check flue damper for
proper operation. When the
damper is in a closed posi-
,tion, the damper blade should
be UP and the damper control
lever pushed all the way to
the rear of the firebox. When
the damper is open, the dam-
per blade is DOWN and dam-
per control lever is pulled ail
the way to the front of firebox.
Note: In Manufactured
Housing, lireplace

sections first before inserting
through the thimble.
2) The height of flashing and

not exceed
13'6" from ground
levelfor transportation pur-
poses. In(Figure
32). it is
assumed the floor level of the
Manufactured Homeis
30"
above the ground.
Step
5: The heignt of vertical
flue pipe supported oniy by
the fireplace must not exceed
30 feet. Flue heighls above 30
feet must be supported by a
Model 634unitized stabilizer
installed at 30 foot intervals.

I
Note: The Model 8-S4 unitized
stabilizer adds
2% inches net
effective height to the total
chimney system.
Figure 32
Install the model 8-54 stabili-
zer by fitting inner section
down into respective section
of preceding flue pipe and
locking outer stabilizer sec-
tion into place over the outer
flue pipe. Position for proper
clearance through framed
opening and nail straps
securely (under tension, in
"shear") into place on fram-
ing. Use
8d nails. Attach
successive lengths of flue
pipe directly to stabilizer
using same technique as
described in Step 3.
Note: Do not apply excessive
pressure to any subsequent
chimney sections following
the stabilizer when installing.
Insure each subsequent chim-
ney section is securely
attached, however, by testing
as notedinStep

Step 6: Select proper Superior
roof flashing, depending on
the pitch of roof. Use chart
below for selection:

Step 9: Superior locking
bands (Model
8LB) may be
required
if chimney extends
too high above the roof1
flashing. As a general rule, if
the chimney extends more
than
6 feet above the roof1
flashing, the use of locking
bands is advisable to
strengthen the chimney joints.

INSTALLATIONS
Special Offset Instructions
To clear any overhead

your chimney system using
Suoerior 30" offset and return
elbows (Models TFB-30 and

Use two elbows - an offset
.elbow to initiate the offset
and a return elbow to terni-
nate it.
The offset and return elbows
may be attached together, or
a section or sections of chim-
ney in between may be used,
but do not exceed
20' in total
length between elbows (see
Figur2 43). If sections of pipe
exceed
i0' between elbows, a
chimney stabilizer must be
used at the 10'point. The sta-
bilizer support straps must

onpage 76 for reference.
:step 1: Determine the offset
distance where flue is to pass
through the first ceiling
-
dimension "A". To find lhis
point on your ceiling, first
determine the centerpoint for
'avertical chimney following
the instructions for vertical
installation.
Measure height to the ceiling
from top of fireplace

sion
"0". Use offset Elevation
Chart to find dimension "A".
Mark point where you will
drive your nail to show the
centerpoint for your offset
ceiling cut.
Step
2: Proceed by using the
Straight Up Instailation
lnslructions for cutting and
framing ceiling and roof
openings.
Note: See Fram~ngand
Dimension Chart for the sizes
of the ceiling androof open-
ings. The size of the roof
opening varies with the
degree of the pitch of the
roof.

GAS LINE
This provision is intended for
connection to a decorative
gas appliance only, in accor-
dance wirh the National Fuel
Gas Code, ANSi
Z 223.1-i960.
If you're installing a gas line,
concect it now. The gas
knock out location is deter-
mined by a
1 118" round
indentation located at the
bottom and slightly off center
on the side refractories. THE
KNOCK OUT
IS ALWAYS TO
BE REMOVED FROM INSIDE
THE FIREBOX. If removal is
attempted !rom the outer
wrapper into the firebox, side
'refractory damage may occur.
With a medium-sizedhammer,
lightly tap the surface of the
indentation. The refractory
material is very thin in the
area of the indentation, and
can be easily removed. Once
a small hole is made in the
knock out, continue to tap
lightly until the desired diame-
ter is obtained. The knock out
area can be removed to a
total diameler of
1 118"; how-
ever, the entire knock out
does not have to be removed.
With the refractorv knock out
removed :o the disired diarne-
ter, remove knock out on
outer wrapper and install gas
line. Use only
'/2" black iron
pipe through fireplace wall for
cocnection to a 106 lighter or
gas log unit inside the fire-
box. Outside, the iron pipe
connects to a gas shut o:i
valve recessed flush into a
wall or floor and controlled by
a removable valve key for
safety.
Always plumb gas line instal-
lation pe: state and local
codes. Check all connections
with soa9 suds; leaks will
bubble. Never test any gas
line connections with a match
or open flame.
IMPORTANT: Re-pack insuia-
tion in square hole around
gas line to seal.
CAUTION: WHEN USING THE
