SOURCE: Vulcan Eco 80 Ducted Heater. Fan Runs

Heaters have fans to enable the unit cool down to avoid overheating in the unit. The fans are meant to blow air into the unit at strategic positions. Most units are made such that the fan comes on when the units temperature rises to a certain level and when the temperature drops the fans are supposed to stop. temperature sensors are fitted into the unit to regulate this system to create a balance in the unit. The sensors are supposed to switch the fan on when needed and also turn it off when it is supposed to. If the sensors are bad then the fan continues to run until power is cut from the unit or if the switch which the sensors trigger becomes bad then the fan runs continuously. Fixing this is quite technical in nature and would take an expert to determine which sensors and switches to replace exactly.
Hope this solution has been helpful?

F1 08 f2 08 f3 08 f4 08 error codes vulcan comfort control what does it mean


What sort of machine is it? Refrigerated, Ducted, Gas? To do a full reset correctly, you must switch off at the main isolator next to the unit or at the meter box and leave it off for at least 15 minutes. A quick on / off does not reset it properly. If the unit is a refrigerated split system , and the outdoor is running but the machine is not blowing cold outside and hot inside (On heating mode) It could be due to a gas leak / shortage.

F1/08 vulcan fault code


Hi Geoff,

Is your heater a ducted gas heater how old is it and what does the wall control look like.

No it cant really be fitted as the evap system uses much larger duct and also in some cases people use a different type of duct that when running a gas heater threw it it tends to melt with the heat. Your best option would be to get new ducting that way you can size it correctly so you dont have air alance issues down the track.

I have a Vulcan Ultra 21E ceiling ducted unit The LED flashing fault is no 8 which is a gas interruption. The unit fan runs, ignition starts full flame and gas flows for about 2 secs then shuts down The...


Just been thru a similar problem with my Climate Technologies Vulcan High Efficiency Ducted Gas heater which in this case is installed under the house. This heater is about 7 years old and I have previously (2 years back) refurbished the controller by replacing the main power supply electrolytic filter capacitors.

I also had a communication problem with the Touch pad Thermostat which in the end required replacing the entire touch pad as one of it's voltage regulators had gone intermittent (Touch pads are available on E-Bay). To operate the heater while the touch pad was out of commission I installed a manual switch between the heat contacts on the heater controller. Closing the switch causes the heater to permanently run if it has no thermostat. Once communication with the touch panel was restored we were able to try and find the intermittent heater fault.

Again I have been getting Fault Code 08 "Gas Interruption" however the heater was lighting OK and then going out after about a minute or so. In the end I found 2 distinct heater faults.

Fault 1 was the flame sensor where the weld between the wire and flame probe rod had broken but it was still touching. This meant it was sensing Flame OK and then later would go open with expansion as the temperature rose. I fixed this by replacing the Flame Probe with a new one sourced from Reece HVAC.

At this point I celebrated thinking it was fixed!

Fault 2 after the flame sensor issue was cleared the fault still persisted but slightly less often.
The heater was cycling 3 times to get going and then locking out, requiring a reset from the touch thermostat or heater controller board. Sometimes the heater would achieve a onging burn for a long period, and other times just locking out after 3 tries.

Careful observation of the flame, through the observation holes after it lit, showed correct flame sensing but as soon as the nominal 65C duct temperature was reached the combustion fan (modulates) throttles back too far and the flame goes out, the flame sensor switches off and gas valve is then closed. The pressure differential across the burner manafold controls the Gas flow rate so if the combustion fan goes too slow the flame goes out due to lack of gas.

On the control board there is a potentiometer marked "MIN GAS RATE" this needs to be tweaked clockwise until the burner remains lit when the nominal 60-65C duct temperature is reached. Don't turn it up too far or the heater may not throttle back enough and end up going out on overheat.

Once a stable flame is achieved when throttled, try the heater in the economy mode which uses a lower recirculating fan speed and check the flame still remains lit. My problem was most obvious in the Econ mode.

Hope this helps someone else - It took me over a year to solve this one. NeilP

Bonaire Vulcan ducted heating system flashes F08 and HC 01. What do I do?


I was able to fix my Pyrox ducted gas heater (flashing between HC01 and F08 by pressing the reset button on the main PCB located in the main heating unit.
The reset button is located next to a set of indicator led's. It's easy to get to by just removing the covering shroud.

Pilot lights but won't stay on in my older style vulcan space heater. thermo couple was replaced last year.any ideas that i could try thanks


Most common cause of pilot light problems is air movement. If your space heater exhausts gas through the roof, ensure the cap is on and level. If not, outside air movement will blow out the pilot. If you do not have an exhaust gas duct, check that the unit is positioned so that it does not blow air back onto itself from walls, furniture, etc, and ensure no other devices that move air are aimed towards the unit. The unit also needs to be placed away from central ducting, including return vents.

Hope this helps!
