I'm recovering refrigerant today to start decommissioning a Lennox packaged roof unit that consists of 3 Pulse 21's that I've never seen before and thought people may find it interesting, this is a full prefab unit manufactured by Lennox. I haven't seen one in my 16 years in the trade so I'm sure many others haven't either, so I figured I may as well share.
Wow. It's more like a custom shed that's customizable with existing residential units. I've only ever seen 3 pulse furnaces and I'm quite certain a won't ever come across a packaged system like this.
When cleaning the flame sensor wasn't hard enough ;D
Right? Let me just get my offset socket adaptor and reach into this small square cutout to pull out the spark plug erghhh sorry flame sensor
I've changed 100s of those heat exchangers back in the day. Those look like a nightmare to work on let one change out a heat exchanger.
Must sound great with three running at once :)
