If the heater is installed,
turn off the gas and turn off the electric power.
If the heater is a fan model with standard two-point suspension, the two
hanger brackets in the option package will have to be installed to convert the
heater to four-point suspension. Remove both of the outer side panels of the
heater and follow the instructions in Step 1.
If the heater is a fan model with factory-equipped optional four-point sus-
pension or a blower model, remove only the left outer side panel (left when
facing the rear of the heater) and proceed to Step 2. (This panel must be
removed to make wiring connections.)
1. Install Hanger Brackets - Applies to fan model with two-
point suspension only
Since the power venter adds weight to the back of the heater, additional sus-
pension points must be used to maintain the unit in a level position without
placing a load on the gas valve and piping. With the outer side panel removed,
the factory-installed hanger bracket is visible.
On the side of the heater, position a hanger bracket from the option kit between
the rear of the heater and the factory-installed hanger bracket. Remove the
screw from the inner side panel at this location. Attach the hanger bracket to
the heater by putting the screw through the slotted hole in the hanger bracket
and re-inserting it into the inner side panel (See
FIGURE 2). Slide the hanger
bracket up against the top of the inner side panel and tighten the screw..
Install the other hanger bracket on the opposite side of the heater.
If the heater is installed, suspend it from the two new suspension points. Be
sure that the heater is level and that the hanger rods are locked to the heater
as shown in
FIGURE 3.
Venter Operation
DANGER: This power venter is to be installed by a qualified service agency in accordance
with these instructions and in compliance with all codes and requirements of authorities
having jurisdiction. Failure to follow instructions could result in death, serious injury, and/
or property damage. The agency performing this work assumes responsibility for this
installation.
HAZARD INTENSITY LEVELS used in these instructions:
1. DANGER: Failure to comply will result in severe personal injury or
death and/or property damage.
2. WARNING: Failure to comply could result in severe personal injury or
death and/or property damage.
3. CAUTION: Failure to comply could result in minor personal injury
and/or property damage.
When the thermostat calls for heat, the thermostat contacts close the circuit
which, after a delay of approximately 30 seconds, starts the venter. When the
venter starts, air from the venter blower closes the airflow (sail) switch that is
built into the venter. The closing of the airflow switch completes the electric
circuit to the burner controls, opening the gas valve. When the thermostat is
satisfied, the thermostat closes the gas valve and de-energizes the time delay
relay. Approximately 45 seconds after the thermostat is satisfied, the venter
blower stops and the airflow switch resets to the open position.
WARNING: Improper installation, adjustment, alteration, service,
or maintenance can cause property damage, injury, or death.
Read the installation, operation, and maintenance instructions
thoroughly before installing or servicing this equipment.
