ASSEMBLY OUTLINE

Before You Start

Check your inventcry list to
be sure you have all the
necessary parts

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 obstruc­tions, 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 con­structed with a

40"

x

LO"

x

1"
millboard or a durabls non­combustible 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 sup­ply to fireplace

(if

optional fan
assembly is to be installed at
a later time).

5.

Complete finish wall mater­ial, surround and hearth
extension to your own
individual taste.

6.

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-surfaced floor coverings.
It may, however, be placed on
flat wood, plywood, particle
board or other hard-surfaced
materials. Be sure fireplace

Haanh

Plalrom

'

Floor

Figure

rests on a solid continuous
floor or platform so no cold

air can enter room from under
fireplace.

The fireplace may be posi­tioned and then

the framing
built around it, or the framing
may be constructed and the
firepiace pushed into the
opening.

Usualiy, no special floor sup­port is needed for the fire­place; 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 foot­age of the floor space to be
occupied by the system, sur­rounds 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

(Figure

7).

Figure

The hearth strips should
exlend in front of the fireplace

,two inches. In the event

wooden blocking is used to
elevate the fireplace above

the

floor,

a

"2"

lype hearth slrip
Should be fabricaled and used
10 protect the front surface of

the blocking material as well
as the floor beneath the hearth
extension

(Figure

8).

Step

3:

Refer to fireplace
:drawings and specifications
on

(pages

8

and
