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.

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 8762 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 restrictor must be in the closed position
above 10' vertical vent length.
Always maintain a minimum of 1” clearance from
all sides of the vent system to any combustible
material.
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 90
⁰
or four 45
⁰
elbows may
be used in vertical terminations. Whenever
possible use 45
⁰
elbows instead of 90
⁰
elbows
as they offer less restriction to the flue gases.
Vertical terminations may require additional
restriction in order to perform as intended.
Please refer to
Figures 22 - 24
to adjust your
vent restrictor accordingly
