Before using the heater, read and understand ail instructions and follow them carefully. The manufacturer is not responsible for damages to goods or persons due to improper use of units.

GENERAL RECOMMENDATIONS

The hot air heaters run on heating oil. Those with direct combustion send hot air and the combustion products into the room, while those with indirect combustion are fitted with a flue to take the products of combustion away through the  chimney.
Always follow local ordinances and codes when using this heater:

• Read and follow this owner’s manual before using the heater;

• THE INSTALLATION OF THE UNIT SHALL BE IN ACCORDANCE WITH THE REGULATIONS OF THE AUTHORITIES HAVING JURISDICTION. Also, as a recommended installation practice reference should be made to the current issue of CSA B139, Installation Code for Oil Burning Equipment in Canada and NFPA 31 Standard for the Installation of Oil-Burning Equipment in the USA.
  Use only in places free of flammable vapours or high dust content;

• Never use heater in immediate proximity of flammable materials (the minimum distance must be 5 ft);

• Make sure fire fighting equipment is readily available.

• Make sure sufficient fresh outside air is provided according to the heater requirements. Direct combustion heaters should only be used in well vented areas in order to avoid carbon monoxide poisoning;

• A rough estimate of opening required for each gallon (US) of ca- pacity is one square foot for indirect-fired heater and three square foot at heater level, for direct-fired heaters;

• the heater is installed near a chimney to vent products of com- bustion (see the paragraph “CHIMNEY LAY-QUT RECOMMENDATION”) and connected to an electrical switchboard;

• When the heater is connected to a flue pipe, the flue pipe shall terminate in a vertical section at least two feet long and sufficient draft shall be created to assure safe and proper operation of the heater;

• Never block air inlet (rear) or air outlet {front);

• In case of very low temperatures add kerosene to the heating oil -below 20°F

• Before starting the heater always check free rotation of fan; Make sure heater is always under surveillance and keep children and animals aviay from it,

• Connect the power cord to the mains and wait 15 min at least be fore starting heater, to allow pre-heated filter warming heating oil inside the filter;

• Indirect fired units only can be connected to air ducts to distrib- ute warm air, with respect to the max. static pressure declared (see “TECHNICAL SPECIFICATION” sheet);

• Unplug heater when not in use.

OPERATION

Before any attempt of starting the heater is made, check that your electrical supply conforms to the data on the model plate.
Warning
Mains must be fitted with a breaker switch.
Unit plug must be linked to a socket with a mains disconnect switch
Do not touch exhaust gas outlet danger of burns.
The heater can only work automatically when a control device, such as for example a thermostat or a timer, is connected to the gener- ator. Connection to the heater is made by removing the socket cover (4) and inserting the thermostat plug.
To start the machine you must:

• if connected to the thermostat, tum the switch to (ON + & );
• if not connected to the thermostat, twrn the switch to (ON) When unit is started for the first time or is started after the oil tank has been totally emptied, the flow of oil to the burner may be impaired by air in the circuit. In this case the control box will cut out the heater and it might be necessary to renew the starting procedure once or twice by depressing the reset button (1).

Hand filling the filter cup with fuel may help to prime the pump.
Should the heater not start, check that oil tank is full and depress reset button (1).
Should the heater still not work, please refer to chapter “0B- SERVED FAULTS, CAUSES AND REMEDIES”.
STOPPING THE HEATER
Set main switch (3) on “0″ position or turn thermostat or other control device on lowest setting.
The flame goes out and the fan continues to work for approx. 90 sec. cooling the combustion chamber.
SAFETY DEVICES
The unit is fitted with an electronic flame control box. In case of maltunction this box wil cut in and stop the heater, at the same time the pilot lamp in the control box reset button (1) will light up. Heaters are also equipped with an overheat thermostat safety cut out which vill stop the heater in case of overheating. This thermostat will reset automatically but you vill have to depress button (1) on con- trol box before being able to restart the heater.
TRANSPORT
Warning
Before making any attempt to restart heater find and eliminate reason of overheating.
Before heater is moved it must be stopped and unplugged. Before moving the heater wait till it has totally cooled off and make sure oil tank cap is securely fixed.

IMPORTANT
Before using the space heater, carefully read all of the instructions and follow them scrupulously.
The manufacturer cannot be held responsible for damage to persons and/or property caused by improper use of the equipment.
This instruction manual is an integral part of the equipment and must therefore be stored carefully and passed on  with the unit in the event of a change of ownership.
GENERAL RECOMMENDATIONS
The space heaters run on heating oil #2. Direct combustion versions send hot air and combustion products into the room, while indirect combustion versions are fitted with a flue to discharge the fumes through the chimney.
Always follow local ordinances and codes when using this heater:

• Follow the instructions in this booklet very carefully;

• THE INSTALLATION OF THE UNIT SHALL BE IN ACCORDANCE WITH THE REGULATIONS OF THE AUTHORITIES HAVING JURISDICTION. Also, as a recommended installation practice reference should be made to the current issue of CSA B139, Installation Code for Oil Burning Equipment in Canada and NFPA 31 Standard for the Installation of Oil-Burning Equipment in the USA;

• Use only in places free of flammable vapours or high cust content;

• Never use heater in immediate proximity of flammable materials (the minimum distance must be 5 ft;

• Make sure fire fighting equipment is readily available; Ensure that the machine resting surface or ground is not made of flammable material;
  Make sure sufficient fresh outside air is provided according to the heater requirements. Direct combustion heaters shculd only be used in well vented areas in order to avoid carbon monoxide poisoning;

• A rough estimate of opening required for each gallon (US) of capacity is one square foot for indirect-fired heater and three square foot at heater level, for direct-fired heaters;

• the indirect combustion heater is installed near a chimney to take away the fumes (see the paragraph “CHIMNEY LAY-CUT RECOMMENDATION”) and connected to an electrical switchboard;

• Never block air inlet (rear) or air outlet (front);

• In case of very low temperatures add kerosene to the heating oil;

• Make sure heater is always under surveillance and keep children and animals away from it;

• Before starting the heater always check free rotation of ventilator;

• Unplug heater when not in use.

SAFETY DEVICES
The heater is fit with an electronic device that controls the flame and the maximum safe temperature by means of a photocell, two overheat thermostats, an air pressure switch and a fan start thermostat.
The electronic device controls startstop times and trips the safety in case of malfunctions. It has reset button (13) that can assume different colours (Function Light) depending on the function mode:

• off: heater is in stand-by, waiting for heating call ;
• steady green: heater functioning normally;
• steady red: heater in safety stop;
  To restart heating after a safety stop, push reset button (13) for 3 seconds.

Warning
NEVER do more than two restarts in a row:  uncombusted diesel fuel may accumulate in the combustion chamber and suddenly flare up at the next restart.
If the safety stop persists, you have to find and eliminate the cause of the stop before you restart the heater.
Warning
See “TROUBLESHOOTING” to identify the cause of the malfunction.
OPERATION
Before switching on the heater and, therefore, before plugging it into the electrical power supply, check that the power supply specifications are the same as those stated on the identification plate.
Warning

• The power line must be grounded and fitted with a residual current circuit breaker.
• The heater plug must be inserted into a socket equipped with a mains switch.

The heater must be placed on a flat, stable, and levelled surface in order to prevent it from overturning and/or diesel leaks from the tank filler cap.
The heater can work in “ventilation” mode turning the switch (14)to the fan motor starts, while the burner is off. The heater works in *heating” mode, tuming the switch (14) to : the burner motor start, immediately followed by ignition and combustion. When the combustion chamber becomes hot, the coolin fan motor starts.
To select the heating power level, tumn the swicth (18) to the position corrispondent to the first stage (I S) or second stage (II S)

In heating mode the heater can run automatically when connected to a thermostat. Note: if not operating with thermostat the plate plug(64) must remain connected to panel.
When unit is started for the first time or is started after the oil tank has been totally emptied, the diesel flow to the burner may be impaired by ai in the circit. In this case the control box will cut out the heater and it might be necessary to renew the starting procedure once by depressing the reset button (13) If the heater does not function, the first things to do are:

1. Check that the tank still contains some diesel;
2. Push reset button (13);
3. If the heater sl does not function, see TROUBLESHOOTING” to identify the cause of the malfunction.

HVF 410HD

Warning
Never stop the machine by unplugging the electrical plug: this could cause overheating.
STOPPING THE HEATER
Set main switch (14) on *0” position o turn thermostat or other control device on lowest setting.
The flame goes out and the fan continues to work for approximately 90 sec. cooling the combustion chamber.
TRANSPORT
Warning
Before moving the heater:

• Stop the heater as indicated in the “STOP” paragraph;
• Cut electrical power by removing the plug from the electrical socket;
• Wait until the heater cools.

Before moving the heater, make sure the oil tank cap is securely attached.
Warning
Diesel may leak during handling and transport: the fuel tank cap is not sealed. This allows air to enter and allows the tank to be emptied while the heater is running.

The heater can be supplied in a mobile version (with wheels) or wall version mounted on a support structure with anchors for fastening by means of ropes or chains. To move the mobile version, just grip the heater by the support handle and roll it on the wheels. The second version must be lifted by using a lift truck or similar equipment.
In this case, make sure that the ropes andlor chains are securely attached and that they are in perfect condition before you start to move the heater.

MAINTENANCE

To ensure correct heater function, you have to clean the combustion chamber, burner, and fan at regular intervals.
Warning
Before starting any maintenance procedure, ALWAYS:

• Siop the neater as indicated in the “STOP” paragraph;
• Cut electrical power by removing the plug from the electrical socket;
• Wait until the heater cools.

Every 50 hours of operation:

• Disassemble the filter cartridge, remove it, and clean it with clean diesel fuel;
• Disassemble the external cylindrical fairing and clean the inside and the fan blades;
• Check the condition of the leads and of the high-voltage connections to the electrodes;
• Disassemble the burner and clean all of its parts. Clean the electrodes and set the gap to the value specified

ADVANCED TROUBLESHOOTING
Motor and transformer do not operate.
Causes:

1. Incorrect or low voltage supplied to the heater.
2. Fuse in heater is blown. (no green light)
3. Thermostat defective, or not turned up to call for heat.
4. Control board is defective.
5. Reset button has not been reset. (red light on)

*NOTE: Top cover shell of heater needs to be attached during troubleshooting (will affect operation of airswitch and photocell).
Solutions:

1. Incorrect or low voltage supplied to the heater. Most indirect oil heaters require a minimum of 108 volts to operate properly. A multi-meter set to measure volts can be used to check the amount of voltage at the end of the extension cord(s). If the measured voltage is too low, the length of the extension cord (s) must be shortened or a thicker gauge extension cord must be used.
2. Fuse in heater is blown. Locate and remove the in-line fuse of the heater. Set a multi-meter to measure ohms of resistance. Place a multi-meter probe on each end of the fuse. The multi-meter should read zero ohms (continuity) or the fuse is blown. If a new fuse blows immediately, check for possible causes. Check for incorrect voltage to the heater. Make sure the total amperage draw of all equipment running on the circuit is not too great. If the supplied voltage and total amperage draw are correct, check the wiring in the heater for correctness and possible shorts.
3. Thermostat is defective or not turned up to call for heat. Turn the thermostat up to the highest possible setting and try to start the heater. Next set a multi-meter to measure voltage coming out of the thermostat. If approximately 120 volts is not measured, the thermostat is defective.
4. Control board is defective. Using a multi-meter set for volts, check the hot and neutral wires which bring voltage into the control board. If proper voltage is reaching the board then the control board is defective. Check fuse on control board.
5. Reset button has not been reset. Push the reset button and try to start the heater.

Motor does not start, but ignition spark is present
Causes:

1. Control board is defective.
2. Motor is defective.
3. Motor start capacitor is defective.
4. Fuel pump seized

Solutions:

1. Control board is defective.Locate the terminals of the control board that connect to the motor wires. Use a multi-meter set to read voltage and check for approximately 120 volts to the motor when the heater is turned on. If no voltage is observed the control board is defective. Check fuse on control board.
2. Motor is defective. If the control board and the motor start capacitor check ok and the fuel pump is not seized, the motor is defective.
3. Motor start capacitor is defective. The capacitor may be tested using a multi-meter set to the lowest possible ohm range. First “short” the capacitor by momentarily placing a screwdriver across the two capacitor terminals. Then place the multi-meter probes on the two capacitor terminals. The multi-meter should read close to zero ohms (continuity) first, then slowly move to infinity on the multi-meter. If not then the capacitor is defective.
4. Fuel pump seized. With the heater unplugged, stand behind the heater and attempt to turn the fan blade clockwise by hand. If the fan blade is difficult to turn, undo the connection between the motor shaft and the pump shaft. Attempt turning the fan blade again. If the motor now turns freely, the pump has seized up. If the fan blade is still difficult to turn, the motor is defective.

Motor runs, no visible ignition and heater reset (red light) comes on
Causes:

1. Fuel filter is dirty.
2. Spray nozzle clogged.
3. Air proving switch defective.
4. Air entering the fuel pump thru the inlet line.
5. Safety thermostat defective or tripped.
6. Fuel pump is defective/or broken pump coupling
7. Solenoid valve is defective.
8. Control board is defective.

Solutions:

1. Fuel filter dirty. Check the external and internal fuel filters and clean or replace as necessary. Most fuel pumps contain an internal fuel filter located where the inlet line enters the fuel pump.

2. Spray nozzle clogged. Remove and inspect the spray nozzle. Clean or replace as needed. Do not clean the nozzle orifice with anything metal as this may enlarge the orifice.

3. Air proving switch is defective. Try to start the heater without ducting. Indirect oil heaters have an air proving switch wired between the control board and the solenoid valve. The air proving switch is normally open and requires air from the turning fan blade to close the switch and send power to the solenoid valve. Set a multi-meter to measure voltage. With the fan blade turning, check for voltage coming out of the air proving switch to the solenoid valve. If no voltage is read, next check for voltage at the control board terminals out to the air proving switch. If voltage at the control board is read, the air proving switch is defective. If no voltage is read at the board, the control board is defective.

4. Air entering the fuel pump thru the fuel inlet line. If air enters the pump it will lose its prime and will not maintain adequate pump pressure. First make sure all fittings, including the fuel filter on the inlet line are tight. If you still suspect air is entering the pump, start eliminating portions of the inlet line until the air leak is found. Start this process at the fuel tank end of the inlet line. It may be necessary to draw fuel from a small container rather than the fuel tank.

5. Safety thermostat defective or tripped. Also called overheat switch. Some indirect oil heaters have a safety thermostat wired between the control board and the solenoid valve. If the heater becomes too hot this normally closed switch will open and interrupt power to the solenoid valve.
   Use a multi-meter set to measure ohms. Place the multi-meter probes on the two male terminals of the safety thermostat. If the multi-meter shows infinity (no continuity) the safety thermostat is defective. If the switch opens up before the heater becomes hot, the safety thermostat is defective.

6. Fuel pump is defective. The output pressure of the fuel pump can be checked by placing a high pressure fuel gauge into the gauge port of the fuel pump. Use a gauge with enough capacity to measure the high pressure your particular heater can produce. Use the adjustment on the pump to set the pump pressure to the manufacturer’s specification. If you do not have a fuel gauge, you may slightly loosen the pump’s output line connection and place a rag there. Run the heater briefly and see if fuel reaches the rag. If no fuel is pumped, check the connection between the motor and the fuel pump to make sure the motor can turn the pump. Also check the external and internal fuel filters for blockage, and clean or replace if necessary. The fuel pumps internal filter is usually located where the fuel inlet line enters the pump. Check to make sure motor is rotating pump.

7. Solenoid valve is defective. Call tech service for assistance.

8. Control board defective. Use a multi-meter set to measure voltage. Take a voltage reading on the control board terminals that send input power to the transformer. If proper voltage is not present, the control board is defective. Check fuse on control board.

Motor runs, fuel sprays, but no spark is observed
Causes:

1. Electrodes damaged or gapped incorrectly.
2. Transformer defective.
3. Control board defective.

Solutions:

1. Electrodes damaged or gapped incorrectly. Inspect the electrode tips for melting. Make sure there are no cracks in the porcelain insulation. Check the electrodes with the manufacturer’s specifications for gapping and spacing. Adjust or replace the electrodes as needed.
2. Transformer defective. Transformers require a ground connection to function properly. Check the transformer’s ground wire or mounting tabs for a good ground connection. Use a multi-meter set to measure voltage. Check the voltage in to the transformer from the control board for approximately 120 volts. Do not attempt to measure the transformer’s output voltage with an ordinary multi-meter. The transformer may also be bench tested for proper output arc.
3. Control board defective. Use a multi-meter set to measure voltage. Take a voltage reading on the control board terminals that send input power to the transformer. If proper voltage is not present, the control board is defective. Check fuse on control board.

Motor runs, fuel sprays, spark is present, but heater will not ignite
Causes:

1. Pump pressure incorrect.
2. Electrodes damaged or gapped incorrectly.
3. Nozzle dirty or worn.
4. Air damper setting is incorrect.
5. Transformer output is weak.
6. Ducting is improper.
7. Venting is improper.
8. Fuel contains water or contaminants.

Solutions:

1. Pump pressure incorrect. Using a high pressure fuel gauge, check the output pressure of the fuel pump. If necessary, use the pump’s adjustment to set the pump pressure to the manufacturer’s specifications.
2. Electrodes damaged or gapped incorrectly. Inspect the electrode tips for melting. Make sure there are no cracks in the porcelain insulation. Check the electrodes with the manufacturers specifications for gapping and spacing. Adjust or replace the electrodes as needed.
3. Nozzle dirty or worn. Clean the nozzle using compressed air. Never use anything metal to clean the nozzle as this may enlarge the orifice. With enough use, fuel traveling under high pressure thru the nozzle orifice can enlarge the orifice. This is especially true when diesel fuel is used. Clean or replace the nozzle as needed.
4. Air damper setting is incorrect. Use the manufacturers specifications for the air damper setting and adjust as needed.
5. Transformer output is weak. Remove the transformer and perform a bench test.
6. Ducting is improper. Follow the manufacturer’s recommendations concerning maximum duct length and diameter.
7. Venting is improper. Follow the manufacturer’s guidelines for venting.
8. Fuel contains water or contaminants. Visually inspect the fuel in the tank for water bubbles or contaminants. Drain, flush, and re-fill tank as needed.

Heater ignites, runs less than one minute and shuts down
Causes:

1. Photocell is dirty, misaligned or defective.
2. Control board is defective.
3. Fuel pump defective.
4. Fuel filter dirty.

Solutions:

1. Photocell is dirty, misaligned or defective. Check that the photocell is aimed correctly and is free of dirt. If necessary, clean the photocell “eye” with a soft, dry cloth. If resistance is zero or infinite, photocell is defective (10K scale on multimeter).
2. Control board is defective. If the heater’s spray and spark are correct, the photocell and control board must work together to recognize the combustion flame has become established. Therefore if a new photocell does not correct this symptom, the control board is defective.
3. Fuel pump is defective. If the fuel pump will not achieve or maintain proper output pressure, the fuel pump is defective. Check the pump’s output pressure with a gauge.
4. Fuel filter dirty. Inspect the internal and external fuel filters and clean or replace as needed.

Heater ignites, runs several minutes, then shuts down.
Causes:

1. Fuel pump is defective.
2. Overheat thermostat is defective.
3. Ducting is improper.
4. Venting is improper.
5. Nozzle is dirty.
6. Fuel filter is dirty.
7. Control board is defective.
8. Fuel contains water or contaminants.
9. Solenoid valve is defective.

Solutions:

1. Fuel pump is defective. If the fuel pump will not achieve or maintain proper output pressure, the pump is defective. Check the fuel pump output pressure with a gauge.
2. Overheat thermostat is defective. Also called a safety thermostat or limit switch. Some heaters are equipped with this. Set a multi-meter to measure ohms of resistance. Perform this test immediately after the heater shuts down and the overheat thermostat is still hot. Place the multi-meter probes on the two male terminals of the safety thermostat. If the multi-meter reads infinity (no continuity) the safety thermostat is defective. Remember that if the heater is over firing due to high pump pressure, worn nozzle, or is improperly ducted or vented, the safety thermostat will heat enough to shut the heater off.
3. Ducting is improper. Always follow the manufacturer’s recommendations regarding maximum duct length and diameter. Failure to do so can result in heat building up in the heater until the safety thermostat contacts open and shut the heater off.
4. Venting is improper. Follow the manufacturer’s recommendations concerning proper venting. Failure to do so can result in heat building up in the heater until the safety thermostat contacts open and shut the heater off.
5. Nozzle is dirty. If dirt reaches the nozzle, the spray can be adversely affected and cause a shut down. If possible observe the spray pattern and clean the nozzle as needed.
6. Fuel filter dirty. Check the internal and external fuel filters. Clean or replace as needed.
7. Control board is defective. For the heater to function, the control board must send proper voltage to three components: motor, transformer and solenoid valve. Using a multi-meter set to measure voltage, check the appropriate control board terminals for proper voltage out to these three components. If proper voltage to any of these three components is not observed, the control board is defective.
8. Fuel contains water or contaminants. Visually inspect the fuel in the tank for water bubbles or contaminants. Drain, flush, and re-fill as needed.
9. Solenoid valve is defective. Use a multi-meter set to measure voltage. Check for proper voltage at the solenoid valve. If proper voltage is read and the solenoid valve will not stay open and allow fuel spray, the solenoid valve is defective.

Heater ignites, but combustion is poor or uneven
Causes:

1. Fuel pump pressure is incorrect.
2. Nozzle dirty or worn.
3. Electrodes damaged or gapped incorrectly.
4. Fuel filter is dirty.
5. Air damper setting incorrect.
6. Whirl disk dirty or mis-aligned.
7. Ducting is improper.
8. Venting is improper.
9. Fuel contains water or contaminants.

Solutions:

1. Fuel pump pressure is incorrect. The output pressure of the fuel pump can be checked by placing a high pressure fuel gauge into the gauge port of the fuel pump. Use a gauge with enough capacity to measure the high pressure your particular heater can produce. Use the adjustment on the pump to set the pump pressure to the manufacturer’s specifications.
2. Nozzle dirty or worn. Clean the nozzle using compressed air. Never use anything metal to clean the nozzle as this may enlarge the orifice. With enough use, fuel traveling under high pressure thru the nozzle orifice can enlarge the orifice. This is especially true when diesel fuel is used. Clean or replace the nozzle as needed.
3. Electrodes damaged or gapped incorrectly. Inspect the electrode tips for melting. Make sure there are no cracks in the porcelain insulation. Check the electrodes with the manufacturer’s specifications for gapping and spacing. Adjust or replace the electrodes as needed (page 5/17).
4. Fuel filter is dirty. Inspect the internal and external fuel filters and clean or replace as needed.
5. Air damper setting incorrect. Use the manufacturer’s specifications for the air damper setting and adjust as needed. (see Diagram B, page 17) 6. Whirl disk dirty or mis-aligned. Inspect the whirl disk and clean if necessary. If the disk is warped or mis-aligned, replace or adjust as needed.
6. Ducting is improper. Follow the manufacturer’s recommendations concerning maximum duct length and diameter.
7. Venting is improper. Follow the manufacturer’s guidelines for venting.
8. Fuel contains water or contaminants. Visually inspect the fuel in the tank for water or contaminants. Drain, flush, and re-fill tank as needed.

Heater ignites but flame is excessive
Causes:

1. Fuel pump pressure is too high.
2. Nozzle is worn.
3. Incorrect fuel.

Solutions:

1. Fuel pump pressure is too high. Attach a high pressure fuel gauge to the fuel pump and check the pump pressure. Adjust the pressure to the manufacturer’s specifications with the adjustment on the fuel pump.
2. Nozzle is worn. With enough use, the impurities in the fuel traveling under high pressure thru the nozzle orifice can enlarge the orifice. This is especially true when diesel fuel is used. A worn nozzle can cause the heater to run “rich” and possibly over fire the heater enough to activate the safety thermostat and cause a shutdown. Replace after 400 hours of operation.
3. Incorrect fuel. Only use the manufacturer’s recommended fuels. Never use gasoline, paint thinner, solvents, or other flammable liquids. If you suspect the fuel is incorrect, drain, flush and re-fill the tank with proper fuel.

1. DIAGNOSTICS
If the control unit is in lockout status, by keeping the reset push-button pressed for about 5 seconds, the diagnostics routine will be activated and the cause leading to the lockout condition will be displayed. Pressing the reset push-button again enables to reset the device and to terminate the diagnostics routine. The following table shows a description of the diagnostics messages provided by the red LED blinking:

FOR 2 RED BLINKS CAUSE MAY BE:

• No flame at 1st start up (review page 12 and 13)
• Other causes may be defective over heat limit switch (check for continuity)

FOR 4 RED BLINKS CAUSE MAY BE:

• Photocell senses light before start- up (make sure cover is on and photocell installed properly)

FOR 7 RED BLINKS CAUSE MAY BE:

• Out of fuel
• Filter or nozzle blocked
• Broken fuel line (intake sucking air)
• Bad photocell
• Overheat limit switch tripped

2. SIGNALLING DURING OPERATION
In the various operating conditions, the device can signal its operating status by means of a multicolour LED located on the on-board lockout signal. The meaning of the colours is the following: 3. RESETTING THE CONTROL UNIT
When the control unit goes to non-volatile lockout, to reset the system press the reset push-button till the lockout signal turns off (< 5 seconds).

• Non-volatile lockout (manual reset), in order to reset the system, the reset button must be pressed (less than 5 seconds).
• Volatile lockout, turn selector switch to OFF position, hold reset button for a least one minute, red light should go out, let control board “reboot” for at least another minute before attempting to start again.
