Installation Instructions
Wiring
Two conductor non-metallic sheath cable with ground wire is recommended
for recessed installation of these heaters while two conductor, metallic
sheath cable (BX) is recommended for surface installations. Use
number 12 gauge wire for all models. Each heater should be on an
individual, properly fused circuit.
Recessed Installation
1.
Allow 12” (30cm) of service cable for connecting to wall box. Remove
6” (15cm) of the outer jacket and strip the individual conductors 1/4”
(6mm) from the end.
2.
Cut a wall opening 14 9/16” (37cm) high by 11 1/4” (28.5cm) wide
(see Fig 1). Allow a minimum of 2” (5cm) clearance around wall
opening to accomodate heater frame. Depth of wall opening must
be 3 1/4” (8.3cm) minimum, measured from finished wall surface.
3.
Remove the screws securing heater assembly to the wall box and
separate. Keep all screws for heater reassembly.
4.
Remove rear knockout at top corner of wall box and insert 1/2 cable
connector. Bring service leads through connector and secure end of
cable to the connector.
5.
For safety, each wall heater is provided with a grounding screw located
in the upper right corner of the wall box. Connect ground lead and
tighten screw for good electrical connection.
6.
Place wall box in wall opening so the welded side brackets rest on
finished wall surface, and secure box with four #10 Philips head wood
screws, 1 1/2” long (not provided). Insert the wood screws through
the inner set of flange holes at both top and bottom.
Alternate holes are provided in sides of box for mounting to wood
framing. (If wall box is installed prior to application of finished wall
surface, set box to allow for wall thickness).
NOTE: When mounting wall box to hard wall surface, predrill mounting
and clearance holes to prevent splitting wall surface.
7.
Check nameplate on heater to make sure you are connecting to the
Down-Flo Wall Heater
Series EWA-C, 1, 1.5 & 2 KW
proper voltage. Remove any packing material or debris from the
heater assembly and wall box. Then connect service leads.
8.
Place heater assembly into the wall box. Check fan to see that it
turns freely, and service leads are clear of fan area. Secure heater
assembly to the wall box with four sheet metal screws (provided).
9.
Carefully position grille over heater assembly so that protruding switch
and thermostat shaft do not bind against grille. Secure grille to heater
assembly using two Phillips head sheet metal screws (provided).
Push press-fit thermostat knob on shaft.
10. Install the frame to the grille, securing its upper back edge behind
the lip on the top of the wall box, and its lower edge with the single
screw.
11.
Energize heater circuit and test heater (see operating instructions).
Surface Installation
1.
Allow 25” (63cm) of service cable for connecting the heater (see
Fig. 2). Remove all but 2” (5cm) of outer jacket and strip individual
conductors 1/4” (6mm) from end.
2.
Mount surface box to the wall using the four provided #8 - 3/4” Philips
head wood screws, inserted through mounting holes on the back
side flanges. (For hard wall surfaces, pre-drill mounting holes to
prevent splitting wall surface.)
3.
Install 1/2 cable connector in hole on bottom of surface box near
right side. Feed service leads through and secure end of cable to
the connector.
4.
Remove the rear knockout on top of heater wall box near right side
and insert bushing (provided). Feed service wires through bushing.
Secure wall box to surface box with four sheet metal screws (provided
with the surface box). Screws are inserted through the inside holes
on the flanges.
5.
Proceed with steps 7 through 11 inclusive in recessed heater
installation instructions.
