CAUTION - TO REDUCE RISK OF FIRE AND ELECTRIC
SHOCK:
1. Disconnect all power coming to heater at main service panel
before wiring or servicing.
2. All wiring must be in accordance with the National and Local
Electrical Codes and the heater must be grounded.
3. Verify the power supply voltage coming to heater matches the
ratings printed on the heater nameplate before energizing.
4. This heater is hot when in use. To avoid burns, do not let bare
skin touch hot surfaces.
5. Do not insert or allow foreign objects to enter any ventilation or
exhaust opening as this may cause an electric shock, fire, or
damage to the heater.
6. Do not block air intakes or exhaust in any manner. Keep combustible materials, such as crates, drapes, etc., away from
heater. Do not install behind doors, furniture, towels, or
boxes.
7. A heater has hot and arcing or sparking parts inside. Do not use
it in areas where gasoline, paint, or flammable liquids are used
or stored.
8. Use this heater only as described in this manual. Any other use
not recommended by the manufacturer may cause fire, electric
shock, or injury to persons.
9. This heater is not approved for use in corrosive atmospheres
such as marine, green house, or chemical storage areas.
10. Heater must only be installed in a horizontal direction (motor &
thermostat to right) as shown in this manual. Do not install sideways or upside down.
11. Heater must be installed with Back Box.
12. For wall mounting only. The following minimum clearances must
be maintained: Heater to floor - 4 in. (102 mm); Heater to any
adjacent wall - 6 in. (152 mm); Heater to ceiling - 36 in. (915 mm).
13. When wiring, power supply must enter through knockouts in
right end of back box. Do not use the knockouts in left end of
back box.
14. Do not operate heater without grille installed.
15. Do not use heater for dry out. Paint, plaster, sawdust, and drywall sanding dust will damage heater and must be kept out of
heater.

The “G” Series heaters are designed for recessed installation in standard
2 x 4 (50mm X 100mm) or larger stud walls with the back box mounted
as shown in either Fig. 1, or Fig. 2.
NOTE: Heater should be controlled by either built-in thermostat or remote
wall thermostat.
This heater may be wired with standard building wiring (rated minimum
60° C). Refer to Table 3 for appropriate wire size for the heater to be
used.
TO INSTALL BACK BOX (Model RBB)
IN NEW CONSTRUCTION - WALL STUDS 16” OC.
(REFER TO FIG. 1)
NOTE: Please review warning 12 on page 1.
1. Locate back box (model RBB) and back box support brackets (2).
Back box must be installed with mounting rails to the top (see Fig.
1B).
2. Install back box support brackets with foot tabs directed towards the
center of the back box as shown in Fig. 1A and 1B. It may be necessary to bend up slightly the tab on the back box support bracket
to allow insertion under the mounting lances on the bottom of the
back box.
3. Determine which knockout in back box will be used for field wiring
and remove (see back box drawing pg.1). Install strain relief (field
supplied). See warning No. 13.
4. Fish field wiring through strain relief leaving 6” of wire inside box.
5. Insert back box assembly into wall. The front of the back box should
be flush with the finished wall surface or it may protrude slightly. The
back box should never be recessed into the wall. (see Fig. 1C). The
back box support brackets should be resting on the sole plate of the
stud wall to insure proper spacing and leveling (see Fig. 1B).
6. Using four (4) wood screws or drywall screws or four (4) nails (field
supplied), secure back box to studs (see Fig. 1B). Back box support
brackets can now be removed. If not removed, secure to sole plate.
TO INSTALL BACK BOX IN NEW CONSTRUCTION -
WALL STUDS SPACING GREATER THAN 16” OC.
(REFER TO FIG. 2)
NOTE: Please review warning 12 on page 1.
NOTE: Fig. 2 depicts the back box installed with the left side adjoining
stud. For a box with the right side adjoining a stud, reverse the directions
shown below.
1. Locate back box and back box support brackets (2). Back box must
be installed with mounting rails to the top (see Fig. 2B)
2. Determine which side of the back box will adjoin stud and insert back
box support bracket on that side with foot tab directed towards center of back box. On the side of the back box that will not adjoin stud,
install back box support bracket on that side with foot tab directed
towards end of box and secure to box with 3/8” long sheet metal
screw (provided).
3. Determine which knockout in back box will be used for field wiring
and remove (see back box drawing pg. 1). Install strain relief (field
supplied).
4. Fish field wiring through strain relief leaving 6” of wire inside box.
5. Insert back box assembly into wall. The front of the back box should
be flush with the finished wall surface or it may protrude slightly. The
back box should never be recessed into the wall. (see Fig. 2). The
back box support brackets should be resting on the sole plate of the
stud wall to insure proper spacing and leveling (see Fig. 2B).
6. Use two (2) wood screws or drywall screws or two (2) nails (field
supplied) to secure the side of the back box that adjoins a stud. Use
one (1) wood screw or drywall screw or one (1) nail (field supplied)
to secure the foot tab of the back box support bracket (that is on the
end opposite the stud) to the sole plate (see Fig. 2B).
TO INSTALL BACK BOX IN
EXISTING CONSTRUCTION
NOTE: Please review warning 12 on page 1.
1. Locate wall studs to be sure that entire cut-out can be made
between studs. At least one side of the cut-out must be flush with
side of the stud. Bottom of cut-out must be 4” above finished floor
minimum. Make a cut-out in wall 14-1/2” wide X 6-3/4” high (368mm
X 171mm) (see Fig. 3).
2. Determine which knockout in back box will be used for field wiring
and remove (see back box drawing, pg.1). Install strain relief (field
supplied).
3. Fish field wiring through strain relief leaving 6” of wire inside box.
4. Insert back box into cut-out. The front of the back box should be
flush with the finished wall surface or it may protrude slightly. The
back box should never be recessed into the wall. (see Fig. 1C or
2C).

MAINTENANCE
TO CLEAN HEATER: The heater should be cleaned at least annually
for maximum efficiency or more often if used in dirty environment.
Before cleaning be sure power is off and heater is cool. First, remove
knob by pulling straight out, then remove front grille and clean blower
wheel using a vacuum cleaner with a brush attachment. The grille may
be cleaned with a slightly damp rag if desired.
OPERATIONAL NOTICE – RED WARNING LIGHT
Your heater is equipped with an automatic reset limit control that will
automatically turn the heater OFF to prevent overheating. Should this
occur, the red warning light will illuminate and will continue to shine until
the limit resets. Your heater is also equipped with a backup “one shot”
thermal protection fuse that will permanently disable the unit, to prevent
a fire, if the reset limit fails. If the red warning light illuminates and the
heater never restarts, the “one shot” thermal protection fuse has been
activated and you should consult the factory.
THE ILLUMINATED RED WARNING LIGHT SIGNIFIES THE HEATER HAS
BEEN SUBJECTED TO SOME ABNORMAL CONDITION CAUSING IT TO
OVERHEAT. CHECK HEATER TO INSURE THAT IT HAS NOT BEEN
BLOCKED IN ANY MANNER (IF SO, REMOVE BLOCKAGE). IF THERE IS
NO INDICATION OF BLOCKAGE IT IS RECOMMENDED THE HEATER BE
CHECKED BY A REPUTABLE ELECTRICIAN OR REPAIR SERVICE TO
