Qmark GFR Series - Fan-Forced Wall Heaters - Manual (Page 2)

INSTALLATION
INSTRUCTIONS
The “R” Series heaters are designed for recessed installation in
standard 2 x 4 (50 mm X 100 mm) or larger stud walls with the
back box mounted as shown in either Figure 1, or Figure 2.
NOTE: Heater should be controlled by either built-in thermostat
or remote wall thermostat. Models with “T2” suffix are equipped
with built-in thermostat.
This heater may be wired with standard building wiring (rated
minimum 60° C). Refer to Table 3 for appropriate wire size for
the heater to be used.
Note To Installer
The “IF” models do not include a backbox. The Backbox is
ordered separately. In the parts bag for “IF” models, there is a
white label that indicates multiple wattage and must be placed in
the backbox on the bottom right-hand side. When making
wattage changes, the installer must circle the wattage on the
white label before installing the heat deck.
Installation of Back Box (Model RBB) In New
Construction Wall Studs 16” OC. (Refer to Figure 1)
NOTE: Please review Minimum Clearances, Warning #8.
1. Locate back box (model RBB) and back box support brack-
ets (2). Back box must be installed with mounting rails to the
top (see Figure 1B).
2. Install back box support brackets with foot tabs directed
towards the center of the back box as shown in Figure 1A
and 1B. It may be necessary to bend up slightly the tab on
the back box support bracket to allow insertion under the
mounting lances on the bottom of the back box.

wiring and remove (see back box drawing pg.1). Install strain
relief (field supplied). See warning No. 13.

box.
5. Insert back box assembly into wall. The front of the back box
should be flush with the finished wall surface or it may pro-
trude slightly. The back box should never be recessed into
the wall. (see Figure 1C). The back box support brackets
should be resting on the sole plate of the stud wall to insure
proper spacing and leveling (see Figure 1B).
6. Using four (4) wood screws or drywall screws or four (4) nails
(field supplied), secure back box to studs (see Figure 1B).
Back box support brackets can now be removed. If not
removed, secure to sole plate.
