HOW TO INSTALL AN ADDITIONAL GAS VALVE
Determine if the appliance has a redundant gas valve. If it
has a redundant gas valve, proceed to install the
damper assembly.
WARNING: If the appliance does not have a
redundant gas valve, an additional gas valve or a
redundant gas valve must be installed.
1. Shut off the gas and electricity to the gas burner (use the
manual shut off valve in the supply line to the appliance).
2. Locate a position in the supply line between the appliance
automatic gas valve and the burner.
3. Both gas valves must terminate the main gas supply to the
burner(s). Both gas valves must be piped in series and
wired in parallel. (See Diagram A)
4. Install an approved, appropriately sized single function
automatic gas valve in this location downstream of
the existing automatic gas valve. (Follow the gas valve
manufacturer's instructions for fl ow directions and position.)
5. Restore gas line supply, conduct a leak test on the gas piping and control system downstream of the
appliance shut off valve.
6. A typical standing pilot hookup with an added gas valve is shown in Diagram A. Terminals one, two, and
three must be the same polarity. Failure to obtain correct polarity may damage the damper motor assembly.
To set the room thermostat heat anticipator, add an additional 0.10 amps to the specifi ed or measured
control circuit amps.
7. For best results we suggest measuring the current across the thermostat
with a meter. Set the heat anticipator according to the reading plus
0.10 amps.
NOTE: The damper must be open and the burner(s) operating to obtain an
accurate reading.
INSTALLATION OF THE PILOT VENT PLUG
CAUTION: The pilot vent plug is to be installed only on intermittent or direct
ignition systems. Do not install the pilot vent plug on standing pilot systems.
Failure to follow these instructions can cause odor problems and minor
property damage due to moisture.
1. To avoid motor assembly damage, be careful not to turn the
damper gate manually while installing the pilot vent plug.
2. The pilot vent plug is located on the front cover of this
installation manual.
3. Insert pilot vent plug into gate and fold over tabs. (See Figure 2)

INSTALLATION OF THE UNIT

WARNING: Install the automatic vent damper to service only
the single appliance for which it is intended. (See Figure 4) If
improperly installed a hazardous condition, such as an explosion
or carbon monoxide poisoning, could result.
WARNING: To be used only with an appliance bearing a
marking showing the make and model of the device. Required for
installations in Canada.
CAUTION: Horizontal and Vertical Applications
VERTICAL
The vent damper is not position sensitive. You may mount the vent damper in any position. A minimum of 6"
between the device and combustible construction shall be maintained.
HORIZONTAL
To avoid premature failure of the vent damper refer to Figure 3. Avoid mounting the damper directly above
or below the vent pipe. We suggest 1:00 to 5:00 or 7:00 to 11:00 o'clock positions. A minimum of 6"
between the device and combustible construction shall be maintained.

the same polarity. Add 0.10 amps to the specifi ed
or measured heat anticipator setting.
