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?

Inexpensive generators have poorly regulated output and may very well damage sensitive electronic equipment. More expensive generators have better control.

There are several ways to protect equipment running from a generator. You can use a good quality surge suppressor to protect from spikes. However, these won't protect you from dips. For this you need a good quality UPS.
