Generator and Furnace?

I recently had a new furnace installed (ComfortMaker 90+) and I'm concerened about running a generator during power outages. The installer said voltage surges from running the generator could damage the circuit board on the furnace.

Is there any truth to this and if so, is there some type of surge protector or filter that I can use on the furnace when running it off the generator?

I agree with the installer.. I would talk to an electrion (SP) on what type of filter or power surge protector that can be used.

I take it you have power outtage often and long time?

You might want to repost this in the electrical forum. You might get more info there.
Good luck!

Modern furnaces are full of electronic components.

The furnace may not even operate without a ground reference.

Yes, it is possible that your furnace could be damaged by the generator. You should check the waveform specs on your generator.
