WARNING: IF INSULATION IS USED, THE

FIREPLACE MUST NOT BE PLACED DI-

RECTLY AGAINST IT. INSULATION OR

VAPOR BARRIERS, IF USED, MUST FIRST

BE COVERED WITH GYPSUM BOARD,

PLYWOOD, PARTICLE BOARD OR OTHER

MATERIAL TO ASSURE INSULATION AND

VAPOR BARRIERS REMAIN IN PLACE.

Figure 2

Chimney Height

The total height of your completed fireplace

system from the surface the fireplace rests on

to the chimney top must not exceed 80' and

must also meet minimum height requirements.

Refer to the minimum system height chart.

LOCATION OF FIREPLACE

Carefully select the proper location for heat

circulation, aesthetics, chimney obstructions

and clearance to side wall(s). With proper pre-

planning, a slight adjustment of a few inches

can save considerable time and expense later

during construction and assembly.

Chase Enclosure

A chase is a vertical box-like structure con-

structed to surround the fireplace and chimney.

Refer to

Figure 2

for a typical chase configura-

tion. As with all chimney installations, avoid

overhead obstructions such as trees, power

lines, etc. A chase should be constructed and

insulated just like any outside wall. In a cold

climate, we recommend the base of the chase

should also be insulated between the solid

continuous floor beneath the fireplace and the

chase bottom. Chase insulation in a cold cli-

mate installation is not required for safety.

ASSEMBLY OUTLINE

Before You Start

Check your inventory list to be sure you have all

the necessary parts supplied in good usable

condition. Check also for any concealed damage.

Check the operation of the damper. The damper

is controlled through the use of a control lever

located within the firebox opening at the top

center just behind the firebox lintel (

Figure 3

).

The control lever snaps into place at the ex-

treme range of motion, up and back in the

closed position. When pulled forward and

down, the damper is open.

Note: Do not insulate the chase cavity with

blown or fill type insulation materials.

Note: Local codes may not require firestopping

at the ceiling levels for outside chase installa-

tions. However, it is recommended for safety

and the reduction of heat loss.

WARNING: DO NOT PACK OR FILL RE-

QUIRED AIR SPACES WITH INSULATION

OR OTHER MATERIAL. NO MATERIAL IS

ALLOWED IN THESE AREAS.

Carefully consider the position of the fireplace

opening with respect to the location of adja-

cent or nearby stairwells, bath or kitchen ex-

haust fans and/or return air registers for forced

air furnaces/air conditioners that could cause

a smoking fireplace condition if the house is

tightly insulated.

When locating the fireplace, consideration must

be given to combustibles and final finishing.

See

Figure 5

and confine the final location of

combustible finish materials to the "Safe Zone".

DO NOT permanently place furniture or other

items such as decorative pillows within 60" of

the fireplace front face.
