I bought a 1980 Trillium 4500 in the spring. We are going on a trip to New Hampshire from Toronto so I decided to get the furnace and the fridge going on gas, to test them before we might need them.
Good idea to check before you leave but...if you been on this site and have read any on furnace
problems you must know that I have been a year now trying to get mine to run reliably.
Finaly giving up took it to a dealer and $225 later it worked for a week, sitting in the yard then on our trip to the lakes region of Maine it would not ignite.
I am going to take out the furnace...rewire the whole thing and if it still doesn't work I am going to buy a new cat heater.
As I told the wife "As soon as we take it down our 1/8 mile dirt road to the main road, anything can happen".
Hope yours works when you get to your destination.
