Hi joseph_dorri,

Vulcan has backup, if you ever do need a spare part for your Vulcan, it's good to know they are readily available across the country and can be serviced by most plumbers or electricians.

For contact details please click this link.

If you live in Melb, you may also try Tradelink (for the spare parts) or Thermal Products (for any electrical temperature controls etc). Both are in Thomastown.

Hope it helps.

Thank you for using FixYa.

Has the Gas Control Knob been turned from the Pilot position to the ON position? If not, it won't light the burners.

Vulcan Heating &... | Answered on Apr 07, 2011

Hello Chilly - First I'd like to know if this is a new unit or one that has been working until now.

If it had previously working are these the steps you're going through to start it?

START-UP SEQUENCE 1. Press the ON / OFF button. 2. Raise the temperature to HIGH so that the heater calls for heat 3. Within 10 seconds the gas valve will open and the sparker will function. Ignition will commence on a low gas rate and move to high fire after 3- 5 seconds (if high is selected on the control) 4. Within 5 seconds the flame sensor will prove the flame. 5. The fan will not operate until the fan thermostat switch has sensed temperature rise. This may take 2 or 3 minutes. 6. The fan will then start on a low fan speed and after 3 - 5 seconds move to high speed (if High is selected on the control)

If that is or is not what you have been doing let me know and we'll go from there.

SEt to pilot, Push knob, push pezio ignighter until pilot lights, hold for 30 seconds. if it stays lit turn to on, if it doesn't stay lit, you have a bad thermocouple

Yes I would agree with you that t-stat may be gone but have you recently put new batteries in your t-stat. If you have then you can get a new stat from hvac dealer or check with your local hardware stores. I believe that is a honeywell number so should not be hard to find replacement. When you change it just make sure you get wires back on proper terminals. Thank you and have a good new year.

Here are the solution below to solve the problem on your on the mater of do it your self one after the other (step by step).

The first sign of trouble with your water heater's pilot light is usually a cold shower. Your heater's pilot light allows the burner to cycle on and off while maintaining the water in the tank at a constant temperature. When the pilot light goes out for any reason, the thermocouple closes the burner's gas supply valve to prevent gas escaping and filling your house.

When your pilot will not light or does not remain lit, you might be able to save the price of a service call by taking a few minutes to troubleshoot the problem.
Difficulty: Moderately Easy


  1. 1 Remove the pilot light access cover. It is located near the bottom of the tank. If you smell gas, do not attempt to light the heater. If the smell does not dissipate, replace the heater's control valve before proceeding. The control valve is the box located by the access cover. It consists of the on/off/pilot dial as well as the thermostat dial. Consult manufacturer's documentation for replacement instructions on your model.
  2. 2 Turn the thermostat on the water heater to the lowest setting.
  3. 3 Turn the gas control valve to the "Pilot" position.
  4. 4 Inspect the burner area with a flashlight. Clean out any dust or debris before attempting to light the pilot.
  5. 5 Press the gas control valve down in the "Pilot" position, and hold the flame from your match or lighter underneath the pilot light.
  6. 6 If the pilot fails to ignite, check the gas supply to the heater. Make sure all supply valves are open.
  7. 7 If the gas supply is good, the pilot light's orifice or gas jet might be plugged. The orifice is the small tip attached to the pilot light's gas supply tube. Use a small wrench to remove it. Inspect the tip and remove any obstruction by tapping gently against a hard surface or blowing through it. Once you are satisfied that the orifice is clear, try lighting the pilot again and proceed to the next step. If it still does not light, replace the gas control valve.
  8. 8 Remove the flame from the pilot light as soon as it ignites. Continue to hold the gas control valve down for at least two minutes to allow the thermocouple to heat up. The thermocouple is the small metal rod located directly above the pilot light. It is designed to allow the burner to operate only when the pilot light is functioning.
  9. 9 Release the gas control valve. If the pilot light goes out, check the fittings between the thermocouple and the gas control valve. A loose fitting to the control valve can keep the thermocouple from operating properly. If the fittings are tight and the problem persists, replace the thermocouple.

you have air in the gas line , the pilot being so small it would take ages to come through , you need to purge the line to get the air out , se if you can undo the pilot line to pruge it

your intake air pipe is clogged

check the thermal couple

Hello GAVIN Change the the thermocouple anyway if you already did'nt.Check the pilot flame itself it should be stronger than a lighter.It can be turned up/down @ the gas valve.Lastly & very rare I have heard of a sticking gas meter @low pressures in standby mode starving the pilot out.Also when the main burners shut down it should be smooth with out any (snap) blowing it out.

Heating &... | Answered on Aug 19, 2010

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!

Two things have to occur here:

1) The ignitor has to light off the gas. A bad ignitor, or dusty burners can prevent ignition.

2) The thermocouple has to be in the flow of burning gas to prevent a safety shut-down, and has to be working.

And the obvious: you need pressure in the gas line, and the gas valve needs to be open.

Hope this helps you locate the problem!

I couldn't find much information on the net, but you can check the remote transmitter by shining it into a digital camera (you will see white light coming from it). I also read where one person's remote reset itself somehow, here's what they said:

My Vulcan/Bonaire heater remote control goes to reset and stops working frequently. Last 4 error codes are 07 and 08. What's wrong? Anyone with the error code description?

Unfortunately, noone answered the Fixya question.

If the unit contains a thermocouple, it's always a suspect component since it gets and stays hot.
Suspect a bad contactor, if equipped, and any startup capacitor not on the main board.
Good luck, and hope this helps.

what this indicate is that the programming of the system will need to be reset from the control unit

what you are to do to fix up this problem is to put off the system from the main power supply then unplug it from the unit unscrew the strolls then clean up the panel of the control unit i mean the switch or the remote control very well with clean rag or soft brush and be very careful with wires around then couple it back the problem is solve
hope this help?

thank you and thanks for using fixya.
