TO REDUCE RISK OF FIRE, ELECTRIC SHOCK, OR DAMAGE TO
HEATER, OBSERVE THE FOLLOWING:

1. Do not install heater without backbox.

2. Observe the following minimum clearances:
For wall mounting:
Heater to floor - 4.5” (114 mm)
Heater to any adjacent surface - 4.5” (114 mm)
Heater to ceiling - 12” (305 mm)
For ceiling mounting:
Heater to adjacent wall - 12” (305 mm)

3. The heater is hot when in use. Do not install heater behind door,

behind towel rack, in closet, where curtains or drapes could touch or

The D-Series heaters are designed for recessed installation in 2 x 4 or
larger wall studs or ceiling joists using the model D-BB back box with the
discharge grille (the smaller grille) to the top or bottom (see Figure 1). The
heater may be wired using standard building (60 degrees C minimum)
wire. Refer to the specification chart for appropriate wire size for the
heater to be used.

All units in the D series rated 1000 watts and less may be installed
recessed in the ceiling. If installed in the ceiling the heater may be orient­ed in any direction.

Heaters are also approved for surface mounting on walls or ceilings.
Refer to instructions for installation of the DSMK Surface Mounting
Frame.

LATION OF BACK BOX IN EXISTING CONSTRUCTION.”

1. Determine which side of the back box is to be mounted against a
stud or ceiling joist. (see Figure 2). Allow for the thickness of the fin­ished surface when installing the back box. The edge of the back

CHECK OPERATION AND SET THERMOSTAT

1. Switch on power supply to heater.

2. Rotate thermostat knob fully clockwise. Heating element and fan should

come on, causing warm air to flow from discharge grille.

3. Allow heater to operate until room is comfortable, then rotate thermo-

stat counter-clockwise until thermostat clicks. The unit will continue to
cycle on and off to maintain temperature.

4. Increaseor decrease the setting as required until the desired room tem-

perature is maintained.
For best results, the heater should be left “ON” constantly during the
heating season as the thermostat, when properly set, will maintain the
desired room temperature. In the counter-clockwise position, the heater
will remain off. This unit was shipped with a plug button to render the
thermostat tamper resistant. Remove the thermostat knob and insert

plug button in clearance hole guide.
For ceiling mounted units, a remote wall mounted line voltage thermostat

may be installed to control the unit. Follow instructions for the wall ther­mostat. Turn the thermostat knob on the unit to full clockwise position for
maximum heat, remove the knob and insert plug button in clearance hole
guide. Set your wall thermostat to desired set point.
