WALL TERMINATION VENTING
Exterior wall opening:
Determine the exact position of the fi replace so that the vent
pipe is centred (if possible) between two building framing
members. Consult your local building codes prior to proceed-
ing. The vent kit will accommodate up to a maximum wall
thickness of 12 inches.
1) Having determined the position of the fi replace, cut and
frame a 14-1/2 inches opening centred at a minimum
height of 74-1/4 inches above the fl oor. The opening may
be round or square. Height of the opening will vary with
each installation. As the horizontal vent run increases, so
does the minimum vertical rise (see Fig. #17).
IMPORTANT: When locating the opening, it should be
noted that vent terminal clearances must be maintained.
See "Vent Terminal Clearances" section for proper
clearances.
A minimum 2 foot length of pipe is required for any wall ter-
mination. With this minimal vertical rise in combination with a
90° elbow, a maximum horizontal run of 1
8
inches is permitted
(see Fig. #17 and 1
8
). For longer horizontal runs greater than
1
8
inches, increase vertical rise appropriately. The rise and
run must be constrained to the boundaries of the chart shown
in fi gure #17. The horizontal run of vent should have a 1/4"
rise for every 1 ft. of run towards the termination.
HEARTH EXTENSION
While a hearth extension is not required
for this fi replace, one is recommended for
aesthetic reasons. The hearth extension
should be noncombustible and must not
be any more than 1" above the bottom of
the fi replace. If thicker, fi replace must be
raised up accordingly.
Caution: Hearth extensions thicker than
1" will interfere with the window frame.

VENTING
Before installing venting for this unit, the installer should read
these instructions to insure that the proper vent confi guration
has been selected.
Use only Town and Country Termination kits #:
TCVT.WTA - Wall Termination Kit
TCVT.RTA - Roof Termination Kit
Vent system components approved for use with the Town and
Country Fireplace are shown in Figure #15.
Various combinations of vertical and horizontal runs may be
used. Refer to Figure # 17 and 1
8
for details. For optimum
performance and fl ame appearance, keep the vent length
to a minimum and limit the number of elbows. Connections
between each vent system component must be tightly joined,
secured with sheet metal screws and sealed. A horizontal run
of vent should have a 1/4" rise for every 1 ft. of run towards
the termination.
CAUTION: UNDER NO CONDITION SHOULD COMBUSTI-
BLE MATERIAL BE CLOSER THAN 1 3/4 INCHES FROM
THE SIDES AND BOTTOM AND 1 3/4 INCHES FROM
THE TOP OF A HORIZONTAL SECTIONS OF THE VENT
PIPE AND 1 3/4 INCHES FROM A VERTICAL SECTION
OF PIPE.
