SAFETY
Roof Damage Warning And Disclaimer
GSI DOES NOT WARRANT ANY ROOF DAMAGE CAUSED
BY EXCESSIVE VACUUM OR INTERNAL PRESSURE FROM
FANS OR OTHER AIR MOVING SYSTEMS. ADEQUATE VEN-
TILATION AND/OR "MAKEUP AIR" DEVICES SHOULD BE
PROVIDED FOR ALL POWERED AIR HANDLING SYSTEMS.
GSI DOES NOT RECOMMEND THE USE OF DOWNWARD
FLOW SYSTEMS (SUCTION). SEVERE ROOF DAMAGE CAN
RESULT FROM ANY BLOCKAGE OF AIR PASSAGES. RUN-
NING FANS DURING HIGH HUMIDITY/COLD WEATHER
CONDITIONS CAN CAUSE AIR EXHAUST OR INTAKE PORTS
TO FREEZE.

INSTALLATION
Electric Heater
Checklist Before
Installing Electric Heater
1. One of the most important factors for installation is providing adequate power to run the unit.
Under sized wire can lead to voltage drop and
can cause overheating of power leads and poor
performance. Therefore, it is necessary to know
the distance from the unit to an available trans
former and the horsepower of your fan unit.
These two factors will determine the size of wire
needed for efficient operation. See Fan Specifications on the following page.
2. Each electric heater circuit should be wired
through a fused or circuit breaker disconnect
switch.
3. Refer to the Heater Specifications on page 7 for
the recommended slow blow fuse or breaker size
to use when installing your particular Heater.
4. Standard electrical safety practices and codes
should be used. Refer to National Electric Code
Standard Handbook by National Fire Protection
Association.
Installation
Instructions
Be Sure Power Is Disconnected And
Locked Out Before Installation!
Failure To Do So May Cause Seri-
ous Injury Or Death.
1. Be sure that the disconnect and the fan are well
grounded. See machine to earth ground page 9.
2. Check all fasteners on heater elements and other
bolted items to make sure they are tight. If
any are loose, check for proper clearance and
retighten. They may have loosened in shipping.
3. Heater should be bolted solidly to fan and transition.
4. Check and retighten all electrical connections.
They may have loosened in shipping.
5. Make all input power connections to heater as
shown on page 8.
5. A qualified electrician should make all electrical wiring installations.
6
Important! Heater Must Be Interlocked To Fan
Or Connected To An Air
Proving Device. In Event Of Fan Failure
Heater Must Be Shutdown.

Be Sure Power Is
Disconnected And Locked Out
Before Installation!
Failure To Do So May Cause
Serious Injury Or Death.
1. Make field connection of heater
power cord to 5 amp fuse block
in fan as shown in Figure 4.
2. Make field connection of thermostat wires in heater control
box. Thermostat wires are
tagged HI-LIMIT INTERLOCK in heater box.

INSTALLATION
Machine To Earth
Grounding
It is very important that a Machine To Earth Ground Rod be
installed at the fan. The ground
rod needs to be as close to the fan
as possible, but no more than 8
feet away. The ground rod should
be connected to the fan control
panel with at least a #6 solid, bare,
copper ground wire. The grounding rod located at the power pole
will not provide adequate grounding for the fan. The proper
grounding will provide additional
safety if there is a short and will
ensure long life of all circuit
boards used on control circuits,
and the ignition system. The
ground rod must be in accordance
with local requirements.
Figure 4: Use a #6 or approved
size bare copper ground wire.
Install a 5/8" diameter 8' long
copper-clad ground rod, 2'
away from the foundation and
1' below the surface of the
ground or in accordance with
local requirements.
Proper Installation Of Ground Rod
(Ground rods and wires are not supplied by Manufacturer). It is recommended that the rod not be driven into dry ground. Follow these instructions for proper installation.
1. Dig a hole large enough to hold 1 to 2 gallons of water.
2. Fill hole with water.
Dig a hole large enough to hold 1
or 2 gallons of water. Work the
ground rod into the earth until it is
completely in the ground.
3. Insert rod through water and jab it into the ground.
4. Continue jabing the rod up and down. The water will work its
way down the hole, making it possible to work the rod completely into the ground. This method of installation assures
good contact with the surrounding soil, making a proper ground.
5.Connect the bare, copper ground wire to the rod with the
proper ground rod clamp.
6. Connect the bare ground wire to control panel with a grounding lug.
7. Ground wire must not have any breaks or splices. Insulated
wire is not recommended for grounding applications.
Previously Installed Units
It is recommended that previously installed units be checked to see
that a machine to earth ground has been properly installed by an electrician.

OPERATION
Electric Heater
Start Up
1. Turn thermostat knob to its warmest position.
2. Set heater switches to ON position. Red light
should be lit.
3. Watch thermometer on thermostat housing.
When temperaturereaches desired level turn
thermostat knob slowly to the left until heater
lights go out.
Remember: Electric heaters normally give no more
than 5-15 degrees temperature rise.
4. Observe the heater as it runs through a few cycles
to make sure thermostat is set correctly.
Troubleshooting Chart
Service
All Electric Heater Units are designed and built to withstand use in the most severe environments. Take time
out at least once a year to go over the whole unit and
make sure everything is in working order. Preventive
maintenance can save time and money if done on a regular basis.
1. Always disconnect and lock out the power before working on or around fan motor and electrical components.
2. Malfunctioning electrical components should be
checked by a qualified electrician.
3. Heater elements should be cleaned yearly to
avoid excess dust and dirt build up. Excessive
build up on heater may cause heater to perform
poorly and reduce the life of the heater elements.
Symptom
Heater will not start.
Heater runs for short period of
time and kicks out high limit
switch.
Poor performance
Possible Cause
Blown fuse or breaker in
disconnect switch
Blown fuse in fan control box
Defective wiring or loose
connection
Incorrect wire size
Heater high limit kicked out
Defective thermostat
Thermostat not adjusted
Lack of airflow through heater
Defective high limit switch
Defective element
Remedy
Replace fuses or reset breakers.
Replace fuse.
Follow wiring diagram and tighten
any loose connections.
See wire size charts for proper
wire size and change if needed.
Check manual reset. Push in to
reset.
Replace thermostat.
Adjust thermostat settings.
Check for problems with fan or
obstructions that may be blocking
airflow.
Replace high limit switch.
Replace element.
10
Low line voltage at the installation.
Power failure.
Dirt build up on element
Defective magnetic contactor
Call power company after making
sure wire size is correct.
Clean element.
Replace contactor.
