Qmark QFG Series - Electric Fan-Forced Wall Heaters - Manual (Page 3)

TO INSTALL FAN DECK ASSEMBLY
NOTE: Fan deck assembly should not be installed until after the
drywall phase of construction is complete. Dust from drywall
installation and joint compound can be harmful if it gets inside fan
deck components.
1.
Locate fan deck and mounting rails in top of back box.
2. Insert flanges on fan deck into mounting rails and slide back until fan
deck stops (see Fig. 7).
3. Referring to Table 1, determine the wiring diagram for the specific
model heater shown on heater nameplate. Make wiring connections
using appropriate wiring connectors. Connect ground to green col-
ored heater ground wire.
4. Remove 1/2” knockout from grille and install grille using two oval
head screws. Push thermostat knob on thermostat shaft.

5. Using four (4) wood screws or drywall screws (field supplied) or four
(4) nails (field supplied), secure back box to studs (see Fig. 1B). If
wall studs are greater than 16”oc., use only 2 fasteners and on the
opposite end of the back box drive a 1” sheet metal screw (provid-
ed) through hole in end cap. This will draw the back box tight with
drywall when grille is installed. (See Fig. 4.)
