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. Safety 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. Safety decals should be read and understood by all people in the grain handling area. The bottom-right decal warns that the enclosure contains electrical devices carrying high voltages that will cause injury or death. Lock out power before servicing.

2. Safety Decals Safety Alert Decals for Door WARNING Stay clear of rotating blade. Blade could start automatically. Can cause serious injury. Disconnect power before servicing. DC-1225 WARNING Flame and pressure beyond door can cause serious injury. Do not operate with service door removed. Keep head and hands clear.
2. Safety Decals Safety Decals for Bin WARNING Stay clear of rotating blade. Blade could start automatically. Can cause serious injury. Disconnect power before servicing. DC-1225 PNEG-581 Deluxe Vane Axial Heater WARNING Flame and pressure beyond door can cause serious injury. Do not operate with service door removed. Keep head and hands clear.

3. Heater Installation Fuel Connection 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. Liquid Propane Models 1. LP models are designed to run on liquid propane, with liquid draw from the propane tank.
3. Heater Installation Heater Electrical Installation (230V Fans) These instructions are for heater installation on fan units with 230V motors. Be sure power is disconnected and locked out before installation. Failure to do so may cause serious injury or death. 1. Connect power cord to fan control box. 2. Make field connection of wires in fan box as shown in Figure 3B on Page 15. 110V power supply or 0.5KVA 460V to 110V transformer must be used to supply power for heater.

3. Heater Installation Bin Configuration Figure 3C IMPORTANT: When mounting two (2) heaters on a bin it is imperative that they be situated as in Figure 3C. Plenum thermostat must be to the right of master heater and master heater must be to the right of slave heater. 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.
3. Heater Installation Plenum Thermostat Mounting The plenum thermostat is the 4 x 4 white box with knob that is preconnected to heater when heater is ordered with thermostat. 1. 24" to the right side of the transition, drill one (1) 3/8" hole (High-Temperature) or 1-1/2" hole (Low-Temperature) in the center of the plenum in a valley (4.00" corrugation) or hill (2.66" corrugation) on bin sidewall. 2. Insert the probe through the hole. 3.
3. Heater Installation 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.

5. Heater Operation Standard 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. Watch thermometer on plenum and when it reaches desired temperature turn thermostat back slowly until heater cycles off. 8.
5. Heater Operation 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.

5. Heater Operation 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. Figure 5A Adjusting the vaporizer coil on a liquid propane model.
