DO

 

 

NOT INSTALL CLOSER THAN 36" (915mm) TO THE CEILING. FOR

 

 

CEILING MOUNTING, DO NOT INSTALL CLOSER THAN 12” (304mm)

THE HEATER IS HOT

WHEN IN USE.

DO NOT INSTALL THE

HEATER BEHIND DOOR, BEHIND TOWEL RACK, IN CLOSET,

WHERE CURTAINS OR DRAPES COULD TOUCH OR BECOME

SCORCHED BY HEATER, OR WHERE AIRFLOW TO HEATER MAY

BE OBSTRUCTED. KEEP ELECTRICAL CORDS, BEDDING, FURNI-

TURE AND OTHER COMBUSTIBLES AWAY FROM HEATER.

4.Run power supply cable through the connector, leaving about 8” of wire inside the box.

5.Connect the supply cable ground wire to green ground screw provided.

NOTE: Lead holes for a #8 sheet metal screw have been provided in the sides of the back box.. After the finished wall or ceiling has been put up, drive a # 8(m4) sheet metal screw (recommended 1” long) through the side of the box not mounted to the stud. This will prevent the back box from pulling out when installing the heater assembly. (See Figure 1)

INSTALLATION OF BACK BOX IN EXISTING CONSTRUCTION (WALL OR CEILING)

1.

Carefully mark and cut a hole measuring 9-3/8"

(

235mm) wide by 11-

 

1/8"

(283mm) long. One edge of the hole

must be cut along

the

 

edge of

a stud.

 

 

!CAUTION

AN ELECTRICAL SHOCK, FIRE OR WATER DAMAGE COULD RESULT IF WIRING OR PIPING IS DAMAGED DURING CUTTING. MAKE SURE ALL WIRING AND PIPING ARE CLEAR OF AREA BEFORE CUTTING.

GENERAL

The heater is designed for recessed installation in 2” X 4” (50mm X 101mm) stud or larger wall or ceiling sections using the wall box provid-

ed. The heater may also be surface mounted by using the Surface Mounting Frame, Model SRASM or semi-recess mounted by using a SRAS1 (for 1” (25 mm) recess frame) or a SRAS2 (for 2” (50mm) recess frame). All three accessories are ordered separately. The heater may be

wired with standard building wire (60°C). Refer to specification chart (see pg. 4) for correct supply voltage and wire size.

NOTE: The optimum mounting height for this heater is 18" to 24" (450 to

600mm) from floor to bottom of back box.Do not install closer than 2”(50mm) from the floor. Back box may be mounted such that discharge

portion of grille can be oriented down, left, right, or up.

For surface or semi-recess mounting, consult Installation Instructions packed with SRASM, SRAS1, SRAS2

INSTALLATION OF WALL BOX

IN NEW CONSTRUCTION

(WALL OR CEILING)

NOTE: If the finished wall surface is already up, follow instructions for

“INSTALLATION OF BACK BOX IN EXISTING CONSTRUCTION”.

1.Determine which side of the back box is to be mounted against a

 

stud and bend the tabs at the rear corners out 90

degrees so that

 

the back box will be square with the stud after installation. (See

 

Figure 1).

 

2.

Remove one of the knockouts on socket side of the back

box and

 

install a cable or conduit connector.

 

3.

Position back box against side of studs and secure using nails or

screws

 

as shown in Figure 1.

 

NOTE: The back box must be installed with the front edge flush with the fin- ished surface.

Figure 1

2.Proceed to No. 1 through 5 (Installation of Wall Box in New Construction).

FIELD CONVERSION FOR LOWER WATTAGE RATING

NOTE: Refer to specification chart for lower wattage ratings which are available.

To convert heater to lower wattage rating, completely remove red jumper

wire from both heating elements (See Figure 2). Discard this jumper. Be sure remaining wires are securely connected.

Remove red jumper for lower wattage rating

Figure 2

INSTALLATION AND WIRING

OF HEATER / FAN ASSEMBLY

1.Following wiring diagram (Figure 3) connect supply wiring to heater leadwires in back box.

NOTE: For 120 and 277 volt heaters connect the white neutral supply

lead to the heaters white pigtail lead, and connect the black supply lead to the heater black pigtail lead. For 208 and 240 volt heaters change the

color of the heaters white pigtail lead to black by wrapping with black elec- trical tape. (Most electrical codes require the supply leads to be con- nected to black leads). Then connect the two black supply leads to the two black receptacle leads.

2.Secure supply ground wire under green ground screw in back box.

3.Slide supply wiring under retaining straps in back box to hold in place.

4.Insert wiring plug from heater/fan assembly into socket in back box.

5.Fit heater/fan assembly into back box and secure in place with (2) screws provided through the center slots in the fan assembly.

NOTE: Use the screws provided by the factory to install fan deck to the back box.
