Maintain Equipment and Work Area
• Equipment is intended for the use of grain drying only. Any
other use is a misuse of this equipment.
• The operating instructions in this manual pertain to the
common cereal grains as indicated. When drying any other
grain, contact GSI for additional recommendations.
• Be certain that capacities of auxiliary conveyors are matched
to dryer metering capacities.
• On LP fired units, set pressure regulator to avoid excessive
gas pressure applied to the burner during ignition and
operation. Do not exceed maximum recommended
drying temperatures.
• Equipment has sharp edges that can cause serious injury. To
avoid injury, handle sharp edges with caution and use proper
protective clothing and equipment at all times.
• All guards must be in place before and during operation.
Images of guards removed in this manual are for illustration
purposes only.
• Use caution when working around high-speed fans, gas
burners, augers and auxiliary conveyors which can start
automatically.
• Keep hands, feet, and clothing away from moving parts.
• Do not bypass any safety device or interlock.
• Do not enter the dryer or bin while it is operating.
• Do not operate in an area where combustible material will be
drawn into the dryer.

Operating Precautions
READ THESE INSTRUCTIONS BEFORE INSTALLATION AND OPERATION
SAVE FOR FUTURE REFERENCE
1. Read and understand the operations manual before attempting to operate the unit.
2. Keep ALL guards, safety decals, and safety devices in place. NEVER operate dryer while guards
are removed.
3. Keep visitors, children and untrained personnel away from dryer at all times.
4. Never attempt to operate the dryer by jumping or otherwise bypassing any safety devices on
the unit.
5. Always set the main power supply disconnect switch to OFF and lock it in the OFF position using a
padlock before performing any service or maintenance work on the dryer or the auxiliary
conveyor equipment.
6. Keep the dryer and wet holding equipment CLEAN. DO NOT allow fine material to accumulate.
7. On LP fired units, set pressure regulator to avoid excessive gas pressure applied to a burner
during ignition and when the burner is in operation. Do not exceed maximum recommended
drying temperatures.
8. DO NOT operate the dryer if any gas leak is detected. Shut down and repair before further operation.
9. Clean grain is safer and easier to dry. Fine materials can be highly combustible, and it also requires
removal of extra moisture.
10. UseCAUTION inworkingaroundhigh-speedfans,gasburner,augers andauxiliaryconveyorswhich
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 prodsucts, 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
hazardstopersonnelwhich cannot be completelysafeguardedagainstwithoutinterfering with theefficient
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 Manual
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.
Keep the dryer clean. Do not allow fine material to accumulate in the plenum
chamber or surrounding the outside of 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 17 and dimensions on Pages 18 and 19.
Foundation
The dryer should be placed on a reinforced concrete slab located in a well drained area. See Figure 4A
on Page 21, See Figure 4B on Page 22 and Figure 4C on Page 23 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 supply tank. A piping
system is provided on the dryer, including strainer, pressure relief valve, and manual shut off valve.
(See Figure 4D on Page 24.)
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 methanol.
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 24.)
