Qmark CFWF - Counterflow Electric Wall Furnace - Manual (Page 3)

How to Install Your Wall Furnace
Follow the directions carefully to ensure proper installa-
tion and safe operation of your Counterflow Wall Furnace.
All wiring must be in accordance with the National and
Local Electrical Codes and the heater must be grounded
as a precaution against possible electric shock. If you are
not sure what the requirements are, check with your local
authorities for local and state codes affecting installation.
Always get professional help when needed.
Locating the Counterflow
Wall Furnace & Thermostat
1. Furnace can be surface mounted or recessed in any
interior or exterior wall.
Note: The optional rear outlet (CFWFRO) may only be
used on an interior wall.
2. This heater may be recessed a maximum of 5-3/8 inch-
es (137 mm).
Note: Check all clearances. The side of the furnace must
be at least 6 inches (152 mm) from a corner or from a
wall divider.
Note: Your wall furnace works best when it is placed as
near to the center of the space to be heated as possi-
ble.
3. Ensure that electrical service is available at your
desired installation location,
4. To ensure that there are adequate clearances and
service access, the front of the heater must face the
open room. Do not place furniture directly in front of
the Counterflow Wall Furnace.
5. Locate the thermostat approximately 5 feet (152 cm)
above the floor on an inside wall. Since you want the
thermostat to sense average room temperatures,
avoid cold and drafty locations and warm or sunny
locations which could mislead the sensing device in
the thermostat. You have been supplied with approx-
imately 20 feet (610 cm) of thermostat wire. This
should allow you to locate the thermostat approxi-
mately 16 feet (489 cm) from the furnace if the wire is
run through the attic, 12 feet (366 cm) if under the
floor.
6. After selecting a location for your Counterflow Wall
Furnace, ensure that there are no pipes, wiring, etc.
that would interfere with the heater or thermostat loca-
tion. If so, select another location.
Recessed Mount Installation
If you are using the optional rear outlet (CFWFRO), refer
to Optional Rear Outlet Installation on page 7 before pro-
ceeding.
Locate Wall Studs
Use a stud locator or small finishing nails. Drive and
remove a small finishing nail through the wall surface until
you find a stud. Then locate the side of the stud using the
same technique. Leaving that locating nail there, locate
the other side of the stud. Once you have done this, you
should be able to easily locate the next stud. The inside
edge of the next stud should be approximately 14-1/2
inches (369 mm) from the one you just found.

CAUTION
To avoid electrical shock, turn off electrical cir-
cuits that run through the wall where you are
installing the furnace.
