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.
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.
Chimney Height
The total height of your CST and CPF fireplace
systems from the surface the fireplace rests
on to the chimney top must not exceed 80'
(24.4m) and must also meet minimum system
height chart.

WARNING: DO NOT PACK OR FILL RE-
QUIRED AIR SPACES WITH INSULATION
OR OTHER MATERIAL. NO MATERIAL IS
ALLOWED IN THESE AREAS.
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. A chase should be constructed and insu-
lated 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 bot-
tom. Chase insulation in a cold climate installa-
tion 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.

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.
