Proflame 2 Control System & Features
NOTE: OPEN DOOR UNDER THE ASH LIP AND DROP DOWN THE MODESTY PANEL FOR ACCESS TO
ELECTRICAL AND GAS CONNECTIONS.
Bristol DX 8762 Model Overview
Proflame 2 GTMFS System
The Proflame 2 GTMFS is a modular remote control
system that directs the functions of the Bristol. The
Proflame 2 GTMFS System is configured to control
the on/off, main/split burner operation, its flame
levels, and provides Manual and Smart thermostatic
control of the hearth appliance. The system controls
two remotely actuated 120V/60Hz power outlets. The
Fan outlet controls the fan speed through six levels,
and the Auxiliary outlet either on or off. There is also
an additional constantly powered 120V/60Hz outlet.
The system has battery backup power for burner
operation and control during power outages (see
page 9 for specifications).
Figure 1 - Proflame 2 Remote Transmitter
Remote Transmitter
The Bristol comes equipped with a thermostatic
remote control transmitter. The easy to read LCD
display shows all functional abilities as well as a
childproof lockout and low battery indicator. It
displays room temperature readout, set temperature
readout and function status. The remote transmitter is
powered by three 1.5 volt AAA batteries. A Mode Key
is provided to index between the features and a
Thermostat Key is used to turn on/off or index
through thermostat functions.
Figure 2 – Proflame Receiver
Back-up Battery Holder- On/Remote/Off
Switch
The back-up battery holder is powered (6V DC) by
the Control Board and uses four 1.5 volt AA type
batteries for backup during power outages. The slider
switch is set to one of three positions: ON (Manual
Override), REMOTE (Remote Control) or OFF. The
ON selection turns the valve on (to high), and
activates the split flow setting last used if the Remote
becomes inoperative.
Figure 3 – Proflame 2 Fan Control Module
Proflame 2 Control Board
This is the command center for the appliance. The
Control Board allows the pilot to run in the
Intermittent (IPI) mode or the Constant (CPI) mode.
The pilot mode can be toggled between IPI and CPI
via the remote control. The Control Board signals the
burner to light or shut down and provides the ignitor
with the electricity needed for sparking. It is the main
power supply for the entire system when 120V power
Hearthstone Quality Home Heating Products, Inc. Bristol DX Model 8762
9
is available or by the batteries in the Back-up Battery
Holder during a power outage.
The Control Board is equipped with a three-prong
(grounding) plug for protection against shock hazard
and should be plugged directly into a properly
grounded three-prong receptacle. Do not cut or
remove the grounding prong from the plug.
SIT Modulating Gas Valve
The remote transmitter can modulate the valve and
the flame to 6 different settings between high and
low. You can modulate the flame via the remote
yourself or by setting the remote control to the Smart
Thermostat modulation mode. Smart mode means
that as the room temperature approaches the limit set
for shut down the valve will automatically gradually
step down the flame height. The reverse happens
when the room cools - the valve will automatically
gradually increase the flame height.
SIT Split Burner Solenoid
The remote transmitter can toggle between dual
burner, and single burner mode (35,000 Btu/hr or
12,000 Btu/hr).
Pilot Assembly
The pilot assembly consists of a pilot hood, sensor
rod, and ignitor. The ignitor sends a spark to the pilot
hood which ignites the gas and lights the pilot. With
the pilot lit the sensor rod is engulfed by the flame,
flame rectification occurs and the appliance remains
lit. If the sensor does not stay engulfed by the flame
the main burner will not light and the pilot will shut
down.

Control Functions
Pilot Mode
Continuous Pilot (CPI): Running the Bristol 8762 in CPI mode will keep your pilot on even when the thermostat
does not call for heat and when the burner is not lit. This is an advantage in cold climates or under windy
conditions. The “standing pilot” helps to keep the venting warm and generate some draft within the system. The
standing pilot also keeps the firebox warm – greatly minimizing, or eliminating condensation formation on the
glass during startup. The ignitor will automatically spark whenever the pilot mode is switched to CPI, regardless
of the position of the receiver switch. Hearthstone recommends the use of the CPI mode during the heating
season.
Intermittent Pilot (IPI): Using the IPI mode is a more efficient use of fuel as the pilot only ignites when the
thermostat calls for heat.
To switch back and forth between the two pilot modes 1) Press the OFF button on the remote 2) Press the
Mode button on the remote. 3) Press Up or Down on the center pad to toggle back and forth between the two
modes.
Back –up Battery Holder- On/Remote/Off Switch
The Back-up Battery Holder is normally powered by the Proflame 2 Control Board or by four 1.5V AA batteries
during a power outage. This On/Remote/Off switch can be set to three different positions:
On: Manual override allowing the valve to function and ignite the burner without the remote transmitter. The
ignitor will spark automatically.
Remote: Remote Transmitter controls all functions of components.
Off: Turns off the stove. If CPI mode is selected, pilot will remain lit.
PRG Key: Used to synchronize the Transmitter and Receiver initially, and after each battery change (see page
35).

Clearances to Combustibles
Note: Ensure clearances are in accordance
with local installation codes and the
requirements of the gas supplier.
Clearance to Combustibles
Due to high surface temperatures, locate the unit out
of traffic areas and away from furniture and
draperies. Do not place clothing and other
flammable material on or near the heater. When
positioning the unit always maintain adequate
clearances around air openings into the combustion
chamber and allow for adequate ventilation.
Minimum clearances to combustibles must be
maintained as shown in Figures 15 - 17.
Note: The rear clearance to combustibles is
determined by either the unit’s or the vent pipe’s
minimum clearance, depending on whether the
installation calls for vertical rise within the room or a
rear exit, through-the-wall vent pipe.
Ensure you consider the need for access to the gas
control valve access door on the front of the unit as
well as full access for periodic cleaning and
servicing. Also consider clearance for the blower
assembly if present, or planned in the future.
CAUTION: THESE CLEARANCES REPRESENT
MINIMUM DISTANCES IN ALL CASES, WHICH,
THROUGH TESTING IN AN INDEPENDENT
LABORATORY TO ANSI AND CSA STANDARDS,
WILL PREVENT FIRE OR SPONTANEOUS
COMBUSTION. WE DO NOT CONTROL THE
COMBUSTIBLE MATERIALS EXPOSED TO HEAT
BY THIS PRODUCT; THEREFORE, AN
ASSESSMENT MUST BE MADE BY THE
INSTALLER TO PREVENT CONSEQUENTIAL
DAMAGE OF WALLS AND FLOORING.
Hearth Requirement/Floor
Protection
You can place the Bristol directly on any non-
combustible surface or on a wood floor. When
placing the Bristol on any other type of combustible
surface you must install a panel made of metal,
wood, stone, or glass under the appliance. The
panel must extending the full width and depth of the
appliance. Installations must meet all local codes.

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 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 90⁰ or four 45⁰ elbows may
be used in vertical terminations. Whenever
possible use 45⁰ elbows instead of 90⁰ 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
Hearthstone Quality Home Heating Products, Inc. Bristol DX Model 8762

All termination caps must be no less than 18”
(457mm) horizontally from any roof or vertical
surface. See Figure 18.
The termination must fall within the chart in
Figure 24.
The maximum vertical run is 35’
The minimum vent/air intake termination clearances

Horizontal Termination
The termination must fall within the area shown
in Figures 18 & 20.
A minimum of 36" rise is required either directly
off the heater or with the use of a minimum of a
36” snorkel.
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 18 and 20.
Horizontal sections require a 1/4" rise every 12"
of horizontal run.
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.
At the minimum vertical rise of 36”, maximum
horizontal run is 3’. (If a 36” snorkel termination
is used a maximum horizontal run of 3’ is also
applicable.)
