INSTRUCTIONS
GROUND FAULT INTERRUPTER
•
•
•
Since 1971 the National Electric Code (NEC)
has required Ground Fault Circuit Interrupter
devices on all outdoor circuits.
Figure 2 - Plug Adapter
Ifyourresidencewasbuiltbefore1971,checkwith
a qualified electrician to determine if a Ground
Fault Circuit Interrupter protector exists.
Do not use this product if the circuit does not
have a GFCI protection.
•
•
Do not plug this product into an indoor circuit.
Typical accepted GFCI devices are shown in
Figure 1.
•
Avoid the use of an extension cord. Extension
cord may overheat and cause risk of fire. If you
must have an extension cord, the cord shall be
minimum size of 14 awg and not rated less than
1875 watts. Use only 3 wire cord type (3 prong
plug) marked for outdoor use.

SERVICE PREPARATION
(Bottom
View)
A clean work area at the start of each job is essen-
tial for efficient service work. Heaters which are
extremely dirty should be cleaned prior to service.
Cleaning will occasionally uncover the problem
area. Tools needed for the job should be obtained
before work is started. Delays resulting from locat-
ing tools result in lost time and wages.
Tip
Switch
Use caution and common sense when working on
a heater. Always remember that electrical parts can
result in potential shock. Heater parts are hot dur-
ing operation, which could result in burns.

3. If replacement parts are necessary, do not
substitute with non-factory parts (use only
factory authorized replacement parts).
3. Look for obstructions around fan. If you find
an obstruction, turn the product OFF and
UNPLUG THE PRODUCT. Have the product
serviced by a qualified individual.
4. Make sure all electrical connections are secure
and correct prior to connecting heater to a
grounded electrical power source.

an authorized service center.
An over temperature switch (D) shuts the heater off
in the abnormal event a motor were to fail.

2. Open Tubular Heating Element
Test Procedure
Disconnect element wires (black and white).
Attach the ohmmeter leads to the element wire
terminals. Using the 0 to 200 ohm scale, measure
the resistance of the element. If the resistance is
not 8.5 to 11 ohms at 73° F the element is defective
and should be replaced. Note: Resistances may
vary due to element temperature.
1. Fan or Motor Obstructed
Remove obstruction. Clean heater.
2. Dry Motor Bearing
If the fan is difficult to turn, then motor bearings
are defective. Bearings are permanently lubricated,
therefore motor should be replaced.
3. Check for Blocked Air Intake Openings
Check for blockages around vent openings at bot-
tom of heater (see Figure 5, page 6).
3. Open Motor Coil
Disconnect motor wires (black and white). Attach
the ohmmeter leads to the motor wire terminals.
Using the 0 to 200 ohm scale, measure the resis-
tance of the motor coil. If the resistance is not
approximately 6.0 to 6.4 ohms at 73° F, the motor
is defective and should be replaced.
Note: Resistances may vary due to motor
temperature.

REASSEMBLY POINTS
Because this is an outdoor product where the
control of water is important, the following steps
for assembly must be followed.
1. The closed cell foam gasket must seal the hex
shaped pan to the inside of the plastic housing
(see Figure 8). The seal is to be completely
even in the corners of joined parts.
2. The tubular heating element rubber sealing
washers must be against the top surface of the
steel pan and under the brass flat washers as
shown in Figure 9. Nuts on opposite side of pan
must be tightened 1/2 turn past finger tight.
Figure 10 - Thermal Reset Switch
Mounting Screws
3. Apply a SMALL drop of thread locking seal-
ant (rated to 300° F, such as Loctite Thread
Locker Blue) to each of the thermal reset
switch mounting screws (see Figure 10).
Torque screws to 6 to 9 inch-pounds.
4. The tip switch cover must isolate tip switch
from metal base as shown in Figure 11.
5. To complete grounding of heater, all ground
wires must be fixed with screws as originally
assembled by the manufacturer. Additionally,
internal tooth washers must be against the steel
pan and under nuts as shown in Figure 12, for
the tubular heating element.
Figure 11 - Tip Switch Cover
6. No wires should be seen through openings in
bottom of heater (see Figure 13).

7. Tubular heating element must be flush against
bracket (see Figure 14). This centers the ele-
ment to the center hole in metal pan.
8. Fan must be located with set screw at back of
and on flat of shaft (see Figure 15).
9. Heater is equipped with heat reflective tape.
If loose or damaged, replace tape as shown in
Figures 16 and 17. Tape edge should touch top
of louver openings.
