EM SERIES WOODBURNING FIREPLACE
Materials for the Chase
The chase is constructed using framing materials
much the same as the walls in your home. A variety
of materials may be used including brick, stone,
veneer brick, or standard siding materials.
In constructing the chase, several factors must be
considered.
1.
Maintain a 3/4" minimum air space around the
firebox.
2.
Maintain a 2" air space around the chimney.
3.
The chase top must be constructed of a non-
combustible material.
4.
In cold climates a firestop spacer should be
installed in an insulated false ceiling at the 8 foot
level above the firebox assembly. This prevents
heat loss through the fireplace.
5.
In cold climates, the walls of the chase should
be insulated to the level of the false ceiling as
shown in Figure 21. This will help prevent heat
loss from the home around and through the fire-
place.

Installing a Terminal Cap on a Chase
Enclosed Chimney
Construct a chase of desired materials maintaining a
minimum 2" air space around the chimney.
WARNING!
DETAIL INSTRUCTIONS FOR
INSTALLATION OF THE CHASE
TOP, STORM COLLAR AND TERMI-
NAL CAP ARE PACKAGED WITH
THESE PARTS. TO AVOID DANGER
OF FIRE, ALL INSTRUCTIONS MUST
BE STRICTLY FOLLOWED, INCLUD-
ING THE PROVISION OF AIR SPACE
CLEARANCE BETWEEN CHIMNEY
SYSTEM AND ENCLOSURE. TO
PROTECT AGAINST AGAINST THE
EFFECTS OF CORROSION ON
THOSE PARTS EXPOSED TO THE
WEATHER, WE RECOMMEND THAT
THE CHASE TOP AND TERMINAL
CAP BE PAINTED WITH A RUST
RESISTANT PAINT.
WARNING!
NEVER INSTALL A SINGLE WALL SLIP SEC-
TION OR SMOKE-PIPE IN A CHASE STRUC-
TURE. THE HIGHER TEMPERATURE OF
THIS SINGLE WALL PIPE MAY RADIATE
SUFFICIENT HEAT TO COMBUSTIBLE
CHASE MATERIALS TO CAUSE A FIRE.
Install the chimney sections up through the chase enclo-
sure. When using a round terminal cap (TR344), the
uppermost top flashing section of pipe must extend
above the top of the chase collar to allow installation of
the storm collar and terminal cap.
For installations utilizing a telescoping round terminal
cap (TR342), the uppermost chimney section must be
below the top of the chase top, but not more than 14
below the top of the chase top flashing collar.
For installations utilizing a square terminal cap (ST375),
the last chimney section must not be more than 4
below the chase top. See Figure 22.
When installing a TS345 Square Termination, the upper
most chimney section must be no less than 3" below the
top of the chase top or more than 2" above the top of the
chase top.
Attach the chase top (CT35) to the top of the chase.
Install the terminal cap, using the instructions provided
with it.
