I purchased a Pulse 21 in 1993, was having problems with it, and came to find out that the heat exchanger had a large crack at the top weld. Lennox said that they didn't need to pressure test this units because they had fixed the problem. But if you own any type of furnace it would be a safe idea to pressure test your furnace.
