INSTALLATION
INSTRUCTIONS
Unpacking Your New Heater
Remove the heater from the box and inspect it for any damage.
If it appears to be damaged, immediately return it to the store
from which you purchased it.
Tools Needed
You will need the following tools to install your FUH Series
electric heater:
• Screwdriver • Needle nose pliers • Pliers
• Electric Drill and 1/4" (6.35 mm) bit •Adjustable wrench
Hardware Needed
You will also need the following hardware for installation:
•
Enough 10 ga. min. insulated copper conductor (with ground)
wire to run power from the breaker/ fuse to the heater. Only
use copper wire rated at least 75° C. Do not use aluminum
wire with this unit.
•
Proper size fuses and circuit breakers in accordance with the
National Electrical Code. Also see Table 2 Heat Output
Adjustments
•
Screw wood, 3/8" x 2" (9.5 mm x 50 mm) Lag bolts (Qty. 1 or 2).
•
Washer, 3/8" (9.7 mm) (Qty. 2)
•
Wire connectors sized to your application.
NOTE:
For certain applications, conduit may be required (see
Figure 2). Check local electrical codes. If wiring is run in conduit,
be sure there is enough flexible conduit to allow the heater to be
turned if necessary.
Locating the Heater
The heater should be installed out of traffic areas and at least 6'
off the floor. The direction of air flow should not be restricted (ie:
by columns or machinery) and the air flow should wipe exposed
walls, rather than blowing directly at them. When more than one
heater is used in an area, the heaters should be arranged so
that the air discharge of each heater supports the air flow of the
others to provide best circulation of warm air, as indicated in
Figure 3, below.
To prevent a possible fire, injury to persons or damage to the
heater, adhere to the following:
1.
Disconnect all power coming to heater at main service
panel before wiring or servicing.
2. All wiring procedures and connections must be in accor-
dance with the National and Local Codes having jurisdic-
tion and the heater must be grounded.
3. Verify the power supply voltage coming to heater matches
the ratings as shown on the heater nameplate.
CAUTION:
ENERGIZING HEATER AT A VOLTAGE GREATER
THAN THE VOLTAGE PRINTED ON THE NAMEPLATE WILL
DAMAGE THE HEATER AND VOID THE WARRANTY AND
COULD CAUSE A FIRE.
4.
CAUTION
- High temperature, risk of fire, keep electrical
cords, drapery, furnishings, and other combustibles at least
3 feet (0.9 m) from front of heater. Do not install heater
behind doors, below towel racks, or in an area where it is
subject to being blocked by furniture, curtains or storage
materials. Hot air from the heater may damage certain fab-
rics and plastics.
5. To reduce the risk of fire, do not store or use gasoline or
other flammable vapors and liquids in the vicinity of the
heater.
6. When heater is to be wall or ceiling mounted, the anchoring
provisions must be of sufficient strength to support the total
weight of the heater plus the weight of the mounting provi-
sions. Failure to properly secure the supporting members
of the building structure could allow the heater to fall.
7.
The following minimum clearances must be maintained:
For Vertical Airflow, Bottom of Heater to Floor:
6’ (1829 mm) minimum, 11’(3353 mm) maximum
Horizontal Aiflow, Bottom of Heater to Floor:
6’ (1829 mm) minimum, 8’(2438 mm) maximum
Sides of heater to adjacent wall :
Airflow from Horizontal to 45° downward: 13” (330 mm) -
Airflow from 45° downward to straight down 48”
(1219 mm).
Discharge to any object: 36” (915 mm) minimum
8. Do not use this heater for dry out as the paint, plaster, saw-
dust and drywall sanding dust will permanently damage the
heater and must be kept out of the heater.
