4. 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. WARNING Investigate to be sure that the fuel supply system complies with all local codes for LP gas installations. 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 use for vapor draw for long periods of time.
4. Installation IMPORTANT: Heater must be interlocked with fan for safe operation. Heater Power Connection 1. Connect power cord to fan control box. 2. Make field connections in fan box as shown in Figure 4A. 3. Connect deluxe thermostat control as shown in Figure 4A. IMPORTANT: Thermostat must be installed for safe operation.
4. Installation Standard Heater - Second Heater Installation Two (2) standard heaters may be connected to one grain drying system and wired so they cycle together. One of the heaters should have a thermostat connected to it as per the installation instructions. That heater will be referred to as the primary. The other heater (without the thermostat) will be referred to as the secondary. 1. Install relay base (TD-100283) in primary heater control box. 2.
4. Installation Deluxe Heater Electrical Installation Always disconnect and lock out power before working on or around heater. WARNING Standard electrical safety practices and codes should be used when working with a heater. Refer to the National Electric Code Standard Handbook by the National Fire Protection Association. A qualified electrician should make all wiring installations. IMPORTANT: Heater must be interlocked with fan for safe operation. Heater Power Connection 1.
4. Installation Deluxe Heater - Second Heater Installation For Deluxe Units Using HF-7318-1 Control Board Two (2) deluxe heaters may be connected to one grain drying system and wired so they cycle together. One 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 ON/OFF Units 1.
4. Installation Bin Configuration Figure 4E IMPORTANT: When mounting two (2) heaters on a bin it is imperative that they be situated as shown in Figure 4E. 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 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.
4. Installation Plenum Thermostat Mounting The plenum thermostat must be ordered separately from the heater unit. 1. Follow installation instructions provided with the thermostat assembly. 2. Position the housing so that the bolt flanges are vertical, and the cord exits the housing from the bottom. Mark position. 3. Use 6 (4.00") or 8 (2.66") self-drilling screws to mount the housing to the bin sidewall. DO NOT TIGHTEN COMPLETELY. Insert corrugation seal into gap between housing and sidewall.
4. Installation Heater Orifice Setup The factory has set the orifices size for propane, high temperature and natural gas, low temperature. 1. Determine the type of gas to be used: Propane or natural gas. 2. Determine the operating temperature ranges to be used: High or low. Refer to tables on Page 23 and Page 24. 3. For natural gas high temperature applications remove reducer bushing with pressure gauge and remove 7/32" primary orifice from system. Replace reducer bushing and check connections for leaks.
5. Operation Operating Temperature Table IMPORTANT: The below table is not intended as a drying guide. It should be used as a reference for setting maximum plenum temperature for safe operation. Do not exceed plenum temperatures listed in table below.
5. Operation Time Delay Operation - Standard Heater HH-1089E Time Delay Reset Operation The electronic time delay will indicate the operating condition of the heater through the LED light shown in Figure 5A. This light should be on the exterior control panel of the heater when the unit is installed correctly. This light is very helpful in identifying the status of the flame probe (open or closed) and will indicate a lock out condition. Start-Up The light should be ON when the ON/OFF switch is set to ON.
5. Operation High-Low Heater Operation 1. High-Limit and cycling 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. Both lights should illuminate indicating power to the control circuit. 6. Heater should now be lit. If not check to see that all gas is ON. 7. Open adjustment screw on solenoid valve all the way. 8.
5. 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. Operation Adjusting the Vaporizer 1. Vaporizer should be adjusted so the vapor pipe train 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 minute for temperature to equalize. 5. Tighten 5/16" bolt and watch heater run for several minute to verify adjustment. Figure 5C Figure 5D Adjusting the vaporizer coil on a liquid propane model.

6. Service All heaters are constructed of durable weather-resistant materials, so a minimum amount of service should be required. Before the unit is started for the first time each season there are a few items that need to be checked out. All damaged parts should be repaired or replaced. 1. Disconnect and lock out power to fan/heater. Open control box lid and inspect all components for moisture, vibration or rodent damage. Inspect and tighten all loose terminal connections. Replace any damaged wiring. 2.
7. Troubleshooting - Standard Heater Trouble Burner will not fire. No gas pressure on gauge. No ignition spark. Burner will not fire. No gas pressure on gauge. Constant ignition spark. Probable Cause 1. Heater not wired. 1. Visually check fan control box to see if wires are connected. 2. Fan not running. 2. Fan contactor must be energized for heater to run. 3. Blown fuse. 3. Visually check fuse. 4. Bad ON/OFF switch. 4. Check ON/OFF switch contact block for proper installation and continuity.
