PLANNING

This heater is intended to be used to supply supplemental heat from a wall location in new or existing construction. The heater can be operated using its built-in thermostat or a remote thermostat (Broan Model 86W  Line-Voltage Thermostat – purchase separately). Plan to supply the heater with proper line voltage and appropriate power cable.
NOTE: Power can be tapped from a nearby circuit depending on the heater wattage required and the amperage rating of the circuit. The table below lists the ratings for each model.

BOLD ratings are factory wired. See the “OPTIONAL WIRING CONVERSIONS” section on page 3 for wattage and voltage conversion instructions.
The heater can be converted to half-wattage to avoid overloading such circuits.
Follow these basic steps when installing this heater.

• Nail housing to studs.
• Connect the power cable.
• Fasten heater assembly and grille to housing. (FIG. 1)

INSTALLATION

WARNING: To reduce the risk of fire, do not store or use gasoline or other flammable vapors and liquids in the vicinity of the heater.
CAUTION: High temperature, risk of fire, keep electrical cords, drapery, furnishings, and other combustibles at least 3 feet (0.9 m) from the front of the heater and away from the side and rear.

1. Remove the retaining screw, unplug the wiring harness and lift the heater assembly from the housing. (FIG. 2)
   

2. Slide the wiring cover out of the housing. (FIG. 3)
   

(16”-ON-CENTER STUDS ONLY)

1. Choose which side of housing will be mounted directly to a wall stud. Then, insert a mounting bracket, from the opposite side, into the channel at the top of the housing. (FIG. 4)
   NOTE: Locate housing at least 6” from the floor and any adjacent walls.

2. Use a measuring guide on side of the housing to position housing so that it will be flush with the finished wall. Drive two (2) nails through the holes inside of the housing and into a stud. (FIG. 5)
   

3. Extend mounting bracket, level housing, and nail to another stud. (FIG. 6)
   

(24”-ON-CENTER STUDS ONLY)

1. Choose which side of housing will be mounted directly to a wall stud. From this side, push a mounting bracket as far as possible into the channel at the top of the housing. (FIG. 4)
   NOTE: Locate housing at least 6” from the floor and any adjacent walls.

2. Use a measuring guide on side of the housing to position housing so that it will be flush with the finished wall. Drive two (2) nails through the holes inside of the housing and into a stud. (FIG. 5)

3. Secure the two (2) mounting brackets together (with screw supplied). Level housing and nail to opposite stud, as shown. (FIG. 7)
   

WIRING

Installation work and electrical wiring must be done by a qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction codes and standards.

(ALL INSTALLATIONS)

1.  Feed electrical power cable through open knockout in corner of housing and attach with the appropriate connector. Allow 6” of wire inside of the housing.
   NOTE: Use another housing knockout when wiring units in parallel.

2. Connect black to black, white to white, green to green or bare wire. Replace wiring cover. (FIG. 8)

OPTIONAL WIRING CONVERSIONS

1. Conversion to half-wattage. (FIGS. 9 & 10) The heater will produce less heat and use less electricity if converted to half-wattage.
   Disconnect ONE of the two (2) black wires (with insulated terminals) from the motor.

2. 120 VAC to 240 VAC Conversion (FIGS. 11 & 12) (Factory-wired 120 VAC Models 170 and 174 ONLY) These heaters can be converted to operate on
   240 VAC.
   1) Disconnect ONE of the two (2) black wires (with insulated terminals) from the motor.

2. Disconnect the two (2) white wires (with insulated terminals) from each other. Do not remove the white wire from beneath the plastic wire tie.
   3) Connect the black wire to the white wire.

NOTE: When the heater is converted from 120 VAC to 240 VAC, half-wattage conversion is not possible.

COMPLETE INSTALLATION

(NEW CONSTRUCTION)

1. A housing mask has been provided to keep construction dust, drywall spray, paint, etc. from damaging the heater.
