a. For the 9” x 14” rectangular heaters: Slip the collared end over the aeration inlet on the bin. Fasten units together by inserting metal screws through the holes on the collar of the heater. Next, slip the aeration fan as far as possible into the inlet end of the heater. Secure with metal screws through the holes in the heater shell.

b. For the 18” and 24” round heaters: Simply bolt unit to the flanged inlet of the bin inlet port using 3/8" bolts and locknuts.

2. The bottom of the fan's air intake must be at least 12" above ground to prevent it from drawing debris into the fan and heater.

3. Connect heater to the appropriate gas supply; ensure that the gas pressure at the inlet of the heater is within the specified range. The heater will not run on gas that is supplied under 2 psi. The recommended hose size for connection to a propane cylinder is a 1/4" gas hose assembly and for natural gas a 3/8" gas hose assembly.

Important: The person who installs and maintains this heater must carefully read and under-stand the instructions contained in this manual. This person should be certified to work with electrical and gas equipment.

4. Visually inspect the hose assembly and ensure that it is protected from traffic. If there is excessive abrasion, wear, or if the hose is cut, it must be replaced.

5. Ensure that there is no LP-gas container (liquid propane) closer than 6’ from the heater and allow for the following clearances to any other combustible materials:

• Floor: 0• Sides: 1’ • Top: 2’

WARNINGWhen connecting unit for use with propane gas, arrange the cylinders in such a manner that they remain upright and there is no chance of tipping over. Should the cylinder(s) tip over, it will be supplying propane to the heater in the liquid state and may result in serious personal injury and property damage and will void the warranty of the heater.

WARNINGOn stationary propane tanks, the gas supply line must be connected to the top outlet in order for it to deliver vaporized propane.

DO NOT connect gas supply line to the bottom of the tank as this will supply liquid propane which cannot be used in this heater.

4.1.3. SHUTDOWN

1. Close propane/natural gas valve at tank/hydrant.2. Allow heater to run until the flame burns out. This purges the gas out of the

heater plumbing.3. Close gas valve on heater.4. Turn off and unplug heater.5. Allow aeration fan to operate for at least 2 minutes to cool heater down, then

shut off fan.

4.1.4. FLAME INSPECTION

This heater uses a flame generation system that must be functioning correctly in order for the heater to produce the specified BTUs.

1. Inspect the flame through the viewing window on the side of the heater (Figure 4.2). The flame should look blue with an orange tip approximately 2” to 2-1/2” long.

2. If the flame is all blue and short, then the airflow is too high. Either add more grain to the bin to increase the static pressure (lower air flow) or use a smaller aeration fan with less air flow.

3. If the flame is yellowish and long, then airflow is too low. First, ensure that there aren’t any restrictions in gas flow and that the valves are set correctly. If problem remains, either remove grain from the bin to increase air flow or use a larger fan.

6. TroubleshootingNote: See the appendix for parts and electrical diagram details.

6.1. GENERAL1. Move toggle switch to ON position.2. After 15 second delay (pre-purge), the red light on the side of the control box

should come on, the solenoid valve should click open, the igniter inside the burner should spark, and the unit should light within 8 seconds.

3. If unit does not light within 8 seconds, reset by turning toggle switch to OFF. Then, try again.

6.2. HEATER DIAGNOSTIC1. Check the 2 amp fuse.

• Replace if necessary.2. Check for voltage across the toggle switch.

• If there is no voltage present, replace the switch.3. Check for voltage across the air switch.

• If there is no voltage, then the switch is not closing. This may be caused by a defective switch or by not enough static pressure in the bin.

• Replace air switch if defective; if not, bin needs to be filled with more grain.

Note: Heater needs a minimum of 1” static pressure to function.

4. Check for power on L1.• There should be voltage present here but not on V1. • If spark does not come on 15 seconds after the toggle switch has been

turned on, or if the solenoid valve does not click loudly, then the circuit board is defective and needs replacing.

5. Check for voltage across the red light. • If voltage is present then light is defective and needs replacing.

6. Check the hi-limit switch. • If there is power on the side with the 2 wires but no power on the single

wire side, then limit switch is open. The switch is either defective or has overheated and tripped out. Let aeration fan run for 2 minutes to cool unit off.

• If there is still no power present on other side, replace limit switch.7. Check voltage going to the solenoid valve.

• If there is power going to the valve but it is not snapping open, then valve is defective and needs to be replaced.

• If valve is opening and spark is present, then there is a problem with the gas supply.

• Check to see if the gas shut off valves are all open or if hose is pinched off.

HEATER DOES NOT STARTCause SolutionBurnt out fuse • Replace with 2 amp fuse.No grain or not enough in bin

• Add more grain to bin and ensure that aeration duct is covered by at least 3’ of grain.

Defective switch • Test for 120 V across switch leads.

Defective air switch • Test for 120 V downstream side. If there is no voltage, replace air switch.

Defective DSI module• Test for 120 V at terminal L1 on direct spark ignition (DSI) module.

If voltage is present there and if there is no spark, power at termi-nal V1 module is defective.

RED LIGHT COMES ON, BUT FLAME DOES NOT IGNITECause Solution

No spark• Check for spark during ignition cycle by sliding ignition wire terminal off the

coil tower on the DSI module and holding it 3/16” from coil terminal. If spark does not arc across gap, DSI is faulty and should be replaced.

Faulty solenoid • Check for 120 V between terminals V1 and V2 on DSI module; if present, replace solenoid.

Gas supply insuffi-cient

• With propane, ensure that the regulator on the tank is supplying gas within the specified range, and that gas is being drawn off the top of the tank.

• Check for frost on any fittings.• With natural gas, ensure that the supply pressure to the heater is over 2

psi. The minimum size of the gas supply hose/pipe should be 3/8”.• Check for gas supply by removing 1/8” pipe plug from gas valve train;

there should be a steady flow of gas when heater is trying to light. Other-wise, check for gas flow at upstream fittings and correct.

Incorrect air supply• Block off air intake 30% to 50% and try to light; if heater lights, then the air-

flow is too high. Correct by adding more grain to the bin or using a smaller fan.

HEATER LIGHTS BUT STOPS IN LESS THAN 8 SECONDSCause Solution

Too much air• If flame is very blue and burning inside the burner body, restrict air-

flow by 50%. If flame gets longer and more orange, then add more grain to the bin or use a smaller fan.

Not enough air • If flame is very yellowish and burning outside the burner body, then use a larger fan or remove some grain from the bin.

Gas supply insufficient


• With natural gas, ensure that the supply pressure to the heater is over 2 psi. The minimum size of gas supply hose/pipe should be 3/8”.

• Check for frost on any fittings. • Check gas supply by removing 1/8” pipe plug from gas valve train.

There should be a steady flow of gas when heater is trying to light. Otherwise, check for gas flow at upstream fittings and correct.

HEATER LIGHTS AND RUNS 8 SECONDSCause Solution

Reversed polarity• The DSI module is polarity sensitive. If reversed, then the incoming

power cord wires need to be switched. Switch the wires on the extension cord or at the receptacle.

HEATER RUNS FOR OVER 30 SECONDS AND THEN GOES OUTCause Solution

Too much air• If flame is very blue and burning inside the burner body, restrict air-

flow by 50%. If flame gets longer and more orange, then add more grain to the bin or use smaller fan.

Not enough air • If flame is very yellowish and burning outside the burner body, then use a larger fan or remove some grain from the bin.

Poor ground • Ensure that heater has good continuity through the ground wire; if not, correct.

Gas supply insufficient


• With natural gas, ensure that the supply pressure to the heater is over 2 psi. The minimum size of gas supply hose/pipe should be 3/8”.

• Check for frost on any fittings.• Check for gas supply by removing 1/8” pipe plug from gas valve
