10. Use CAUTION in working around high-speed fans, gas burner, augers and auxiliary conveyors
which can START AUTOMATICALLY.
11. Be certain that capacities of auxiliary conveyors are matched to dryer metering capacities.
12. DO NOT operate in an area where combustible material will be drawn into the dryer.
13. The operating and safety recommendations in this manual pertain to the common cereal grains as
indicated. When drying any other grain or products, consult the factory for additional
recommendations.
14. Routinely check for any developing gas plumbing leaks.
15. Before attempting to remove and reinstall the fan blade, contact GSI for the recommended procedure.
Use Caution in the Operation of this Equipment
This dryer is designed and manufactured with operator safety in mind. However, the very nature of a
grain dryer having a gas burner, high voltage electrical equipment and high speed rotating parts,
presents hazards to personnel which cannot be completely safeguarde d against without interfering with
the efficient operation of the dryer and reasonable access to its components.
Use extreme caution in working around high speed fans, gas-fired heaters, augers and auxiliary
conveyors, which may start without warning when the dryer is operating on automatic control.
Continued safe, dependable operation of automatic equipment depends, to a great degree, upon the
owner. For a safe and dependable drying system, follow the recommendations within the Owner’s Manu al
and make it a practice to regularly inspect the unit for any developing problems or unsafe conditions.
Take special note of the Operating Precautions before attempting to operate the dryer.

4. Dryer Installation
Dryer Layout
System Layout
Consider the grain handling system and location of storage bins and existing conveyors when selecting
dryer site, to facilitate wet grain supply and dry grain discharge to conveyors. Other considerations are
prevailing wind direction, fuel and power supply locations, noise and convenience of control location.
Site Location
The dryer should not be operated inside a building or in any area not permitted by electrical code,
fuel installation regulations, or insurance requirements. Do not operate in an area where combustible
material can be drawn into the dryer. Maintain a minimum distance of five feet (5') to other structures.
Refer to dryer specifications on Page 11 and dimensions on Pages 12 and 13.
Foundation
The dryer should be placed on a reinforced concrete slab located in a well drained area. See Figure 4A
on Page 15, See Figure 4B on Page 16 and Figure 4C on Page 17 for recommended dryer foundations
for soils with minimum soil bearing pressure of 3000 lbs/ft².
Liquid Propane (LP) Dryers with Internal Vaporizers
Liquid Draw
The dryer is designed to operate on liquid propane, with liquid draw from the supp ly tank. A piping
system is provided on the dryer, including strainer, pressure relief valve, and manual shut off valve.
(See Figure 4D on Page 18.)
Ammonia Tanks
Do not use propane supply tanks which have previously contained ammonia or fertilizer solutions.
These substances are extremely corrosive and damaging to fuel supply and burner parts.
Oil or Water in Tanks
With liquid draw from the supply tank, any water present in the tank may freeze in the piping and controls
in cold weather. To ensure that tanks are free of moisture, the usual precaution is to purge with met hanol.
Avoid tanks which may contain an accumulation of oil or heavy hydrocarbons from long use on a vapor
withdrawal system.
Natural Gas (NG) Dryers
Gas Volume and Pressure
The dryer is designed to operate on natural gas having a heat value of about 1000 BTU per cubic foot.
The dryer is equipped with a natural gas supply pipe system connected to the heater solenoid valves.
A regulated pressure of 10 PSI must be provided at the connection to the dryer, with gas available in
sufficient volume to maintain operating pressure. (See Figure 4E on Page 18.)

Electrical Power Supply
An adequate power supply and proper wiring are important factors for maximum performance and long
life of the dryer. Electrical service must be adequate enough to prevent low voltage damage to motors
and control circuits. (See electrical requirements on Page 20.)
Transformers and Wiring Voltage Drop
Advise the service representative of the local power supplier that an additional load will be placed on the
line. Check on KVA rating of transformers, considering total horsepower load. The power supply wiring,
main switch equipment and transformers must provide adequate motor starting and operating voltage.
Voltage drop during motor starting should not exceed 14% of normal voltage, and after motor is running
at full speed it should be within 8% of normal voltage.

4. Dryer Installation
Machine to Earth Grounding
It is very important that a machine to earth ground rod be installed at the dryer. Place the ground rod that
comes standard, within eight feet (8') of the dryer and attach it to the dryer control panel with at least a
#6 solid, bare, copper ground wire and the clamp provided. The grounding rod located at the power pole
will not provide adequate grounding for the dryer. The proper grounding will provide additional safety
in case of any short and will ensure long life of all circuit boards, SCR drive, and the ignition system.
The ground rod must be in accordance with local requirements.
Proper Installation of Ground Rod
It is not recommended that the rod be driven into dry ground. Follow these instructions for
proper installation.
1. Dig a hole large enough to hold one (1) to two (2) gallons of water.
2. Fill hole with water.
3. Insert rod through water and jab it into the ground.
4. Continue jabbing 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 proper clamp.
6. Connect ground wire to control panel with the ground lug provided in the control box.
7. Ground wire must not have any breaks or splices. Insulated wire is not recommended for
grounding applications.
Connecting Auxiliary Conveyors
The auxiliary load augers or conveyors can be wired directly to the dryer. The maximum horsepower of
auxiliary that can be wired to the dryer is 10 horsepower. If an auxiliary motor is larger than what is
recommended, then it must be powered from a source outside the dryer, and must use a separate
contractor and overload protection device for each motor. However, the operation of the auxiliaries can
be performed by the control panel.
It is recommended that you contact the local power company and have a representative survey the
installation to see that the wiring is compatible with their system and that adequate power is supplied
to the unit. Remember that the only thing connected to the recommended service amps should be the
grain dryer. Standard electrical safety practices and codes should be used. (Refer to National Electrical
Code Standard Handbook by National Fire Protection Association.) A qualified e lectrician shou ld make
all electrical wiring installations.
