Qmark QTS - Toe Space Fan-Forced Heaters - Manual (Page 2)

NOTE: Heater should be controlled by either built-in thermostat
or wall thermostat. Either is purchased separately. A wall ther-
mostat requires a separate feed from heater to thermostat.
NOTE : Hole location should be 12” from corner and 1/4” above fin-
ished floor.
HORIZONTAl INSTAllATION ONly
This heater may be wired with standard building wiring (rated
minimum 60° C).
1. Cut a 14 1/4” x 3 5/8” (361.9 x 92.1 mm) opening at desired
location as shown in Fig. 1. Keep clearance area free of
obstructions.
2. Remove top cover from heater enclosure by removing the
cover screws.
3. Determine which knockout in enclosure will be used for field
wiring and remove (see figure 1). Install strain relief (field sup-
plied).
4. Fish field wiring through strain relief leaving 6” (12.7 mm) of
wire inside box.
5 FOR BUILT-IN THERMOSTAT, WIRE HEATER AS SHOWN
IN FIG. 2. Run field wiring from circuit breaker box to heater.
Connect to the two black pigtail leads for 240/208V model or
to black and white pigtail lead for 120V model with wirenuts
(provided). Remove the wirenuts securing two blue leads.
Connect the blue leads with wirenuts (provided) to thermostat
lead wires.
6. FOR REMOTE 2 POLE WALL THERMOSTAT, WIRE
HEATER AS SHOWN IN FIG.3. Run field wiring from circuit
