We recently bought a house and there is a combo wood/oil furnace made by Powrmatic. I can't seem to find any information online about operating this unit. I have used the oil side a few times to take the chill out of the house, but have yet to use the wood side for heating. There are two thermostats, one for the oil side, the other for the wood side. The oil thermostat is working as it should. When I turn up the wood thermostat, nothing happens, and I'm assuming this is because there is no fire/the unit is not up to temp. Am I assuming correctly that once a fire is going, I will be able to control the wood side with the thermostat? Or, am I missing something altogether different? I should have asked this question to the local oil company when we had it checked over.
