Venting Terminations
The Bristol cannot be vented jointly with any other
solid fuel or gas appliance. It must be vented directly
to the outside of the building using a proper
termination as listed in this manual. After determining
the venting configuration for your stove, select the
vent system that will best accommodate your
installation.
CAUTION: ENSURE ALL STOVE AND
TERMINATION CAP CLEARANCES ARE
OBSERVED PER THIS OWNER’S MANUAL.
CAUTION: ENSURE THERE IS NO WIRING OR
PLUMBING IN THE CHOSEN LOCATION.
CAUTION: DO NOT RECESS VENTING TERMINALS
INTO A WALL OR SIDING.
Approved Venting Configurations
WARNING: IN HIGH WIND AREAS AND
PARTICULARLY COLD CLIMATES IT MAY BE
NECESSARY TO HEAT YOUR VENT SYSTEM WITH
THE PILOT PRIOR TO IGNITION OF THE MAIN
BURNER. IN THESE INSTANCES IT IS
RECOMMENDED THAT YOU LEAVE THE PILOT
RUNNING FOR 5 MINUTES PRIOR TO IGNITING
THE MAIN BURNER. THIS WILL ALLOW FOR
PROPER START UP AND IGNITION OF ALL PORTS
ON THE BURNER.
There are two types of venting configurations
approved for use with this appliance:
Vertical Venting/Vertical Termination
Vertical Venting/Horizontal Termination
Pipe Clearances to combustibles:
1" to vertical runs
1" below and to the side of horizontal runs
2" from the top of horizontal runs
Vertical Venting and Termination
The Bristol 8763 is approved for venting vertically
through a roof or ceiling. When installing a vertical
vent and/or vertical terminations you must adhere to
the following requirements:
When terminating vertically you must have at
least 10’ of vertical pipe.
The Vent Restrictor Kit must be installed and the
vent restrictor setting in Figure 12 must be
followed. See page 14 for installation
instructions.
Always maintain a minimum of 1” clearance from
all sides of the vent system to any combustible

A listed fire stop is required at any floor
penetration. The opening must be framed in
according to the venting manufacturer’s
instructions.
Steep roofs, nearby trees, or predominantly
strong windy conditions can promote poor draft or
down draft conditions. In this event, an increase
to the height of the vent may improve
performance.
A maximum of two 90⁰or four 45⁰elbows may be
used in vertical terminations. Whenever possible
use 45⁰elbows instead of 90⁰elbows as they
offer less restriction to the flue gases.
All termination caps must be no less than 18”
(457mm) horizontally from any roof or vertical
surface. See Figure 8.
The termination mustfall within the chart in Figure
11.
The maximum vertical run is 35’
The minimum vent/air intake termination clearances
above the high side of an angled roof are as follows:

Horizontal Termination
The termination must fall within thearea shown in
Figures 11 & 12.
A minimum of 24" vertical rise is required directly
off the heater unless a minimum 14” snorkel is
used. In this case, a 12” vertical rise is required
directly off the heater.
Minimum horizontal run at the above conditions is
9”, the maximum horizontal run is 5’ providing a
1/4” rise is provided for every 12” of horizontal
run.
With 3’ of vertical rise from the stove top,
maximum horizontal run is 10’ providing a 1/4”
rise is provided for every 12” of horizontal run.
Use a vinyl siding Stand-Off when installing
against vinyl siding. The termination cap must not
be recessed into the wall or siding. Do not fill air
spaces with any type of insulation material.
A minimum 10” x10” square hole is necessary for
proper pipe clearance through a wall, provided
the vent is positioned to maintain 2” minimum
clearance at the top. A 1” minimum clearance
must be maintained to combustible materials
around the other sides.
All horizontal terminations must also comply with
the clearance specifications to adjacent
structures outlined in Figures 8 &11.
NOTE: For each 90 0 elbow after 2, remove 5' from
the allowable horizontal run. For Canadian
installations: remove 4' from the allowable
horizontal run.
WARNING: FAILURE TO USE ONLY PARTS
SPECIFICALLY APPROVED FOR USE WITH THIS
APPLIANCE MAY RESULT IN PROPERTY DAMAGE
OR PERSONAL INJURY.
Minimum Vent Installation Instructions
1. Install the 24” pipe section onto the starter collar
by fully inserting it and turning approximately ¼
turn clockwise, until the 2 sections are fully
locked. Install the 90º elbow in similar fashion.
2. Move the stove and pipe assembly back until the
90º elbow is flush to the wall. The 24” vertical pipe
should be parallel to the wall. Draw a circle
around the pipe. Use the center of this circle as
the center point of the 10” x 10” square wall pass
through. Cut and frame the wall pass through.
3. Place the interior wall thimble into the 10” x 10”
wall pass through. Secure it with 4 screws (not
provided). Install the exterior portion of the
thimble in similar fashion, overlapping the 2
sections.
CAUTION: FOR BUILDINGS WITH VINYL SIDING,
INSTALL A VINYL SIDING STANDOFF BETWEEN
THE VENT CAP AND THE EXTERIOR WALL.
4. Install the horizontal vent termination on the
outside of the wall. Ensure both of the retaining
straps extend through interior wall thimble. Before
attaching the vent termination to the outside of
the house, run a bead of non-hardening mastic
around its’ outside edges, so as to make a seal
between it and the wall. The arrow on the end cap
should point up. Secure the cap to the wall with
the appropriate screws.
Place the thimble cover onto the 90º elbow. Put
the 9” pipe into the horizontal vent cap, (the vent
pipe must extend into the horizontal vent cap a
minimum of 1-1/4”). Move the stove and vent pipe
into position, insert the 9” pipe into the 90º elbow
and twist to lock it. Secure the straps from the
horizontal vent termination to the interior pipe with
2 sheet metal screws, keeping the screws as
close to wall thimble as possible. Bend or cut the
excess strapping so that the thimble cover will fit
properly. Screw the thimble cover to the wall.

Installing the Vertical Vent Kit
The two identical flat, rectangular steel pieces
are designed to be installed inside the firebox
over the bottom edge of the fresh air intake
openings located at the back of the firebox. Use
the following method:
1) Access the firebox by following the
instructions on pages 9 and 10 of this
manual.
2) Remove the burner and carefully set
aside.
3) Remove the bottom center fresh air duct
screw from both the left and right side inlets.
4) Position the restrictor plates over the intake
openings by resting them on the firebox
bottom and sliding them left or right until the
screw hole in the restrictor plate aligns with
the screw hole in the firebox exposed by
removing the screw in step 3 above.
5) While holding the restrictor plate in position,
re-install the fresh air duct screws removed
in step 3 and tighten snugly.
6) Reverse steps 4-1 to reassemble stove.
When the total vertical vent run in
a particular Bristol installation
meets or exceeds 8’, the Vertical
Vent Kit must be installed in the
stove. This kit is shipped with
every stove and consists of the
three steel components shown
below (not shown to scale).

collar on the top of the stove, from the outside
before venting is attached by the following
method:
1) Note the two tabs extending into the inner flue
collar from the upper manifold housing.
2) Place the restrictor ring into the inner collar
and align the screw holes with the holes in
the tabs.
3) Secure restrictor ring with the two included
screws.

Gas Supply & Connections
Connection Location
The gas supply connection is made to the Bristol’s
gas control valve under the bottom right center of the
unit using a 3/8” male NPT fitting. The supply line
should be ½” diameter, or appropriately sized to
provide a sufficient gas supply to meet the maximum
demand of the unit without undue loss of pressure.
We recommend a flexible line to avoid undue
mechanical load on the valve and to ease thread
alignment, but refer to local codes.
The Bristol is factory equipped to use natural gas
(NG) and requires conversion for use with propane
(LP). A propane (LP) fuel conversion kit is included
with your stove purchase.
Gas Supply
This appliance and its individual shutoff valve must be
disconnected from the gas supply piping system
during any pressure testing of that system at test
pressures in excess of ½ psig. The Bristol must be
isolated from the gas supply piping system by closing
its individual manual shutoff valve during any
pressure testing of the gas supply piping system at
test pressures equal to or greater than ½ psig. Over
pressurizing can damage the control resulting in
leakage or control malfunction.
NOTICE: A QUALIFIED TECHNICIAN MUST
CONNECT THE HEATER TO THE GAS SUPPLY
AND LEAK TEST THE UNIT BEFORE IT IS
APPROVED FOR USE. CONSULT ALL CODES.
WARNING: THE UNIT MUST BE INSTALLED AND
CONNECTED IN ACCORDANCE WITH LOCAL
CODES, OR IN THE ABSENCE OF LOCAL CODES,
WITH THE MOST CURRENT EDITION OF THE
NATIONAL FUEL GAS CODE ANSI Z223.1 (NFPA
54) OR CAN/CGA B149 INSTALLATION CODE.
INSTALLER L'APPAREIL SELON LES CODES OU
RÈGLEMENTS LOCAUX, OU, EN L'ABSENCE DE
TELS RÈGLEMENTS, SELON LES CODES
D'INSTALLATION CAN/CGA-B149
NFPA Code and Hearthstone require the use of a
dedicated sediment trap just upstream of the unit.
Damage to the valve, or other components due to
the lack of a sediment trap are not covered by
warranty (see figure 14).
High Altitude Installations
For high altitude installations consult the local gas
distributer or the authority having jurisdiction for
proper rating methods.
The decreased atmospheric pressure at higher
altitudes affects the heat value of fuel gases. Gas
suppliers typically de-rate the gas intended for use at
elevations above 2000 feet (610 meters). This is not
necessary with the Bristol. If necessary, increase
valve outlet pressure to compensate.
WARNINGS
•Fire or Explosion Hazard. Can cause property
damage, severe injury, or death. Do NOT bend
tubing at gas valve connection point after
compression fitting has been tightened. This
can result in gas leakage at the connection.
•Use new properly prepared pipe free from metal
or material chips. When tubing is used, assure
that ends are square, de-burred and clean. All
tubing bends must be smooth and free of
distortion.
•Do NOT over tighten connections.
Over tightening can damage the control body
resulting in leakage or control malfunction.
•Do NOT remove screws from the gas valve. Do
NOT adjust and/or alter any components
marked with tamper indicating paint. Motor
knob is not to be removed.
•Turn off gas supply at the appliance service
valve before starting installation, and perform a
Gas Leak Test after the installation is complete.
•Install the sediment trap (where required) in the
gas supply line to prevent contamination of the
gas valve (see figure 14).
•Use only your hand to push in or turn, the
gas Control knobs. Never use tools. If a
knob will not push in or turn by hand, do
NOT try to repair it. Call a qualified service
technician. Force or attempted repair will
void warranty and can result in a fire or
explosion.
