Basic Troubleshooting the IMA Drying System |
|
I turn the main switch to "2" and nothing happens. |

1. Has the red reset light illuminated on the burner control box? If yes, press once to reset. The burner will now go through a start up sequence. 2. The maximum thermostat has activated. Press the ▲ and ▼ on the digital thermostat on the front of the control panel. 3. Make sure the thermostat cap is in position (if no room thermostat is simultaneously being used). 4. Make sure the thermostat is set correctly and not sitting directly in the heater airflow. 5. The room thermostat may be defective. Try removing the thermostat and placing the cap on the thermostat connection. If the heater now fires, replace the room thermostat. 6. The capacitor on the burner motor may be defective. Replace if necessary. 7. The fuel pump on the burner may be seized. Remove fuel pump (refer to user manual) and replace if necessary. |
|
The heater starts but no flame is formed. |
|

1. The cut off valve may be closed on the main fuel filter. Open by turning counter-clockwise. 2. The main filter may be clogged. Remove the filter bowl (refer to user manual) and clean the filter if necessary. 3. The filter inside the fuel pump may be clogged. Remove the pump cover (refer to user manual) and clean the filter if necessary. 4. The pump coupling may be defective. Remove the fuel pump from the burner (refer to user manual) and check the pump coupling. The insert should be a D shape. Replace if necessary and remount the fuel pump. NOTE: WHENEVER REMOVING THE FUEL PUMP, ALWAYS MAKE SURE THE CUT OFF VALVE ON THE MAIN FILTER IS CLOSED. 5. The fuel nozzle is blocked or damaged. Remove the burner (refer to user manual) to get to the nozzle. Clean or replace as necessary. 6. The ignition electrodes are faulty or set wrong. Remove the burner (refer to user manual) to check electrodes. Reset, clean or replace as necessary. Settings can be found in the user manual. 7. The magnetic valve does not open. When the burner attempts to fire, a click should be heard right before the flame is formed. If no click, then the valve isn’t opening, allowing fuel to reach the fuel nozzle. Remove the valve and replace if necessary. 8. The main control box is faulty. Remove control box (refer to user manual) and replace if necessary. |
|
The burner starts, a flame is formed, but cuts off after 10-15 seconds, and the red light on the burner illuminates. |
|
|
|
1. The photocell is either dirty or defective. Remove the main control box on the burner (refer to user manual) to get to the photocell. Clean or replace as necessary. |
|
The burner is starting up poorly. |
|
|
|
1. There is insufficient air supply to the burner. Check to make sure the air setting is set correctly (refer to user manual for figures). Make sure nothing is blocking the intake grills on either side of the machine (IMAC 2000s). Leave a gap of 1-2 feet for air supply. 2. There could be a problem with the heat exchanger or burner chamber. Remove the burner (refer to user manual) and remove all side panels. Shine a flash light in to the chamber (where the burner was sitting) and look for any light coming through to the outside. Check for any obvious damage to the heat exchanger or combustion chamber. Contact your supplier about changing these if necessary. |
|
The burner is producing soot/smoking. |
|
|
|
1. The air intake is set incorrectly. Check the air damper settings on the side of the burner (figures can be found in the user manual). Change if necessary. Note: if machines are being used at high altitude, it may be necessary to open the air damper to compensate. Open the air up until no smoke can be seen. |
|
The burner is running in short bursts. |
|
|
|
1. There is too much fuel being used, and the digital thermostat is reaching its limit. This is either due to the pressure being too high at the fuel pump, or the wrong size nozzle being used. Check the pressure at the fuel pump (refer to user manual) and adjust as necessary. Remove the burner (refer to manual) to check the nozzle. Replace if necessary. |
|
The heater can not be switched off. |
|
|
|
1. The magnetic valve on the burner is not closing. Turn the fuel supply off at the main filter to stop fuel to the burner. Remove the magnetic valve and replace if necessary. |
|
The heater is producing white smoke. |
|
|
|
1. There is air in the fuel supply. This will happen if the machine had previously run out of fuel and is being run for the first time. Usually one cycle will clear this. If not, check for any leaks in the fuel supply line. Replace any if necessary. |
|
The heater stops completely. |
|
|
|
1. An overheating problem has occurred and the overheat thermostat has been activated. Reasons for overheating are: A) The rear end of the heater (where fresh air is drawn in, on the side for the IMA range, or the rear for the IMACs) is too close to a wall or an obstruction. Leave a clear gap for fresh air to be drawn. B) If using warm air hose off the front off the machine, make sure there isn’t too much back pressure going back in to the machine (refer to user manual for ratings). Too many bends in the hose WILL cause too much back pressure. Try to keep the hose run as smooth as possible. The same applies if using return air hose. 2. To reset the digital thermostat and restore power to the burner, press the ▲ and ▼ buttons simultaneously on the digital thermostat on the control panel. |
