Wiring
Twoconductornon-metallicsheathcablewithgroundwireisrecommended
forrecessedinstallation of these heaters while twoconductor,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. Allow12” (30cm) of service cablefor connecting to wallbox. 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. Forsafety,eachwallheaterisprovidedwithagroundingscrewlocated
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
finishedwall surface, and secure boxwith four #10 Philipsheadwood
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. Carefullypositiongrilleoverheaterassemblysothatprotrudingswitch
andthermostat shaftdonotbindagainst 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. Mountsurface box to thewall using the fourprovided #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.
Securewallboxtosurfaceboxwithfour sheet metal screws (provided
with the surface box). Screws are inserted through the inside holes
on the flanges.

1. Turn the switch ON. Remember there is a fan delay.
2. Set thermostat by turning the knob to desired room comfort level
(clockwise to increase heat output). Once you have determined
the proper setting to provide the heat level you prefer, you need not
touch the knob again.
3. Turn the switch OFF to turn off heater. To reuse, simply turn the
switch ON - the temperature level you wish has been previously
set.
NOTE: This heater is equipped with a fan delay switch which delays
the fan operation until the heating grid has heated sufficiently to
assure the circulation of only warm air. This same switch permits
the fan to operate after power to the grid has been shut off by
thermostat action, thus utilizing all the heat remaining in the grid.
When the heater is shut down by turning the switch OFF, power to
both fan motor and element is diconnected and the fan motor will
not continue to operate.
WARNING: Should the OVERTEMP light come on, disconnect power to
the heater, turn the switch OFF or turn down the thermostat fully
counterclockwise and call a licenced electrician. DO NOT USE
HEATER UNTIL PROBLEM IS DETERMINED AND FIXED.
Tamper Proof Models
The ON/OFF switch and the temperature regulating thermostat are
recessed so that the continuous grille front panel can be installed
concealing both controls. The thermostat is operated by removing the
frontpanel. The ON/OFF switchcan be operatedby inserting a slender
non metallic rod between grill louvers and turning the switch ON or
OFF.
