Vulcan Wall Furnace turns itself on in the middle of the night - why?

Pyrox?* *Unsure of the name - my tenant is complaining that the heater turns itself on in the middle of the night. I think it might just be a timer set and the tenant doesn't know how to cancel the timer. The wall furnace has a grey front facia -gas heater and looks fairly new. Only purchased house about 2 years ago and don't have a manual to search through to troubleshoot.

This is a link to a vulcan wall furnace manual. I'm not sure from your listing if this is the right one but it may help if programming is similar on these units. If not get back to me by posting more details for me here and I will find the right manual for you. Please do not vote on this until I find you the information you need so you can rate it fixya. Thanks,
If this is what you need let me know when you find out.

SOURCE: Replaced pilot sensor. Still not lighting furnace. Have a high humming sound for about 2 mins then nothing. Any suggestions? Furnace is about 8 years old

The humming sound might be a stuck blower motor or a motor that won't start due to defective starting capacitor.

Does Vulcan Pyrox gas wall furnace have a filter? It seems to cycle on and off too often and the gas seems too high. Also it makes a bang when reigniting. How can I turn the gas down inside it?

get it serviced by a licenced gas fitter / plumber. Should be serviced every two years. Don't risk your life via carbon Monoxide poisoning get a licenced gas fitter /plumber to assess the unit.
