Exterior wall opening:
Determine the exact position of the fireplace so that the vent pipe is centred (if
possible) between two building framing members. Consult your local building codes prior to
proceeding. The vent kit will accommodate up to a maximum wall thickness of 12 inches.
1. Having determined the position of the fireplace, cut and frame a 14 1/2 inch opening
centred at a minimum height of
84 1/2 inches
above the floor. 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. #
37
).
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 4 foot length of pipe is required off the top of the fireplace for any wall
termination. With this minimum vertical rise in combination with a 90° elbow, a maximum
horizontal run of 20 ft. is permitted (
see Fig. #37 and 38
). The rise and run must be
constrained to the boundaries of the chart shown in Fig. #
37
. The horizontal run of vent must
have a 1/4" rise for every 1 ft. of run towards the termination.
Venting
Wall Termination Venting
Before installing venting for this unit, the installer should read these instructions to insure
that the proper vent configuration 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 Fig. #34.
NOTE: Optional Power Vents (TCVT.PVI.25, TCVT.PV7.110 & TCVT.PVCV) require different
venting. Please refer to Power Vent manuals.
Various combinations of vertical and horizontal runs may be used. Refer to Fig. #
36
and
37
for details. For optimum performance and flame 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 with provided
high temperature self adhesive tape. 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 COMBUSTIBLE MATERIAL BE CLOSER
THAN 1 3/4 INCHES FROM THE TOP AND 1 3/4 INCHES FROM THE SIDES OF A
HORIZONTAL SECTION AND 1 3/4 INCHES FROM THE VERTICAL SECTIONS OF THE
VENT PIPE.
