1. Safety Safety Guidelines This manual contains information that is important for you, the owner/operator, to know and understand. This information relates to protecting personal safety and preventing equipment problems. It is the responsibility of the owner/operator to inform anyone operating or working in the area of this equipment of these safety guidelines. To help you recognize this information, we use the symbols that are defined below. Please read the manual and pay attention to these sections.
1. Safety Fuel Warning Do not use propane tanks which have previously been used for ammonia unless they have been purged according to procedures of the National LP Association. Be sure fuel supply system complies with all local codes for LP gas installations. DO NOT USE FLAME FOR LEAK TESTING. Power Warning Be sure power is disconnected and locked out before installation. Failure to do so may cause serious injury or death. IMPORTANT: Heater must be interlocked with fan for safe operation.
1. Safety Safety Instructions Our foremost concern is your safety and the safety of others associated with this equipment. We want to keep you as a customer. This manual is to help you understand safe operating procedures and some problems which may be encountered by the operator and other personnel. As owner and/or operator, it is your responsibility to know what requirements, hazards and precautions exist, and to inform all personnel associated with the equipment or in the area.
1. Safety Install and Operate Gas-Fired Equipment Properly Fuel supply should be installed by a qualified gas technician and must meet local and state codes for gaseous fuel supplies. Disconnect and lock out all fuel sources before servicing equipment. Explosive Gases Prepare for Emergencies Be prepared if fire starts. Keep a first aid kit and fire extinguisher handy. Keep emergency numbers for doctors, ambulance service, hospital and fire department near your telephone.
2. Decals The GSI Group recommends contacting your local power company, and having a representative survey the installation so the wiring is compatible with their system, and adequate power is supplied to the unit. If a decal is damaged or missing, contact: GSI Decals 1004 E. Illinois St. Assumption, IL. 62510 Phone: 217-226-4421 A free replacement will be sent to you.
3. Heater Installation Machine to Earth Ground It is very important that a machine to earth ground rod be installed at the fan. This is true even if there is a ground at the pole 15' away. This ground needs to be as close to the fan as possible, but no more than 8' away. The ground rod should be connected to the fan control panel with at least a #6 solid bare copper ground wire, or in accordance with local requirements. The machine to earth ground provides additional safety if there is a short.
3. Heater Installation Proper Installation of the Ground Rod (Continued) 5. Connect the bare copper ground wire to the rod with the proper ground rod clamp. 6. Connect the bare ground wire to the fan control boxes with a grounding lug. (See Figure 3B.) 7. Ground wire must not have any breaks or splices. Insulated wire is not recommended for grounding. Figure 3B Use a #6 or approved size bare copper ground wire.
3. Heater Installation Fuel Connection Liquid Propane Models 1. LP models are designed to run on liquid propane with liquid draw from the propane tank. Avoid using propane supply tanks that have been used for vapor draw for long periods of time. When using liquid draw systems any moisture that may be present in tank or lines may freeze when system is used in cold weather. To avoid this situation, purge the system with methanol. 2.

4. Installation Plenum Thermostat Mounting (Continued) Figure 4A Plenum Thermostat Mounting on Bin Wall Transition High-Limit Installation 1. Mark location on transition one (1) foot up from the bottom (entrance collar) and centered in the transition. 2. Drill or knock out 7/8" diameter hole on marked location. 3. Install transition High-Limit using supplied self-drilling screws. Figure 4B The transition connecting the heater to the bin with the plenum thermostat in place.
5. Bin Configuration Figure 5A IMPORTANT: When mounting two (2) heaters on a bin it is imperative that they be situated as in above Figure 5A. Plenum thermostat must be to the right of master heater and master heater must be to the right of slave heater. Operating Temperature Table IMPORTANT: Do not exceed plenum temperatures listed in table. Low-Temperature Batch High-Temperature Batch Dry No Stirring High-Temperature with Stirring Continuous Flow (Recirculating) Corn 5°-20° Above Ambient Temp.
6. Second Heater Installation For Units Using HF-7318 Control Board Two (2) Deluxe heaters may be connected to one (1) grain drying system and wired so they cycle together. One (1) of the heaters should have a thermostat connected to it as per the installation instructions. That heater will be referred to as the master. The other heater (without the thermostat) will be referred to as the slave. Installation for Standard Units 1. Install relay base (TD-100283) in master heater control box. 2.
6. Second Heater Installation Electrical Installation (230V Fans) 1. Connect power cord to fan control box. 2. Make field connections of wires in fan box as shown in Figure 6B. 3. Connect deluxe thermostat control (optional) in heater box as shown in Figure 6B. IMPORTANT: Heater must be interlocked with fan for safe operation. IMPORTANT: Thermostat must be installed for safe operation.
6. Second Heater Installation Electrical Installation (460V Fans) 1. Connect power cord to fan control box. 2. Make field connections of wires in fan box as shown in Figure 6C. 110V power supply or 0.5 KVA 460V to 110V transformer must be used to supply power for heater. 3. Connect deluxe thermostat control (optional) in heater box as shown in Figure 6B on Page 17. IMPORTANT: Heater must be interlocked with fan for safe operation. IMPORTANT: Thermostat must be installed for safe operation.

8. Operating Procedure Cycling Heater Operation 1. Thermostat must be wired into heater control box for heater to operate. 2. Open all manual shut off valves to heater unit. 3. Start fan. This will supply power to heater. 4. Turn thermostat dial to its highest setting. 5. Turn toggle switch ON. 6. Heater should now be lit. If not check to see that all gas is ON. 7. Set thermostat to desired setting (see deluxe thermostat manual for adjusting deluxe thermostat control.) 8.
8. Operating Procedure Modulating Valve Operation 1. The modulating valve regulates gas flow through the heater based on sensing unit in the plenum, and maintains a constant drying air temperature. 2. The sensing bulb of the modulating valve should be mounted through the bin wall with the side reading “top” up. The bulb reacts to temperature. It changes the amount of gas (increase or decrease), burning warmer or cooler depending on the position of the valve SET POINT.

8. Operating Procedure Adjusting the Vaporizer 1. Vaporizer should be adjusted so the vapor pipetrain runs warm to the touch (100°F-120°F). 2. Loosen 5/16" bolt on adjustment bracket. 3. Swivel vaporizer away from flame if running too hot, closer to flame if too cold. 4. Move vaporizer only 1" at a time and allow a few minutes for temperature to equalize. 5. Tighten 5/16" bolt and watch heater run for several minutes to verify adjustment.
