Why take the fan out ? I leave the fan inline and take the four small screws out that hold the heat exchanger front cover to the blower assembly using a long t handle Allen key , I have all four screws out in less than five mins , than with a 10 mm socket on my impact gun I remove the nuts holding the front cover onto the heat exchanger and open the whole thing right up. Those fan assemblies are so fragile I don’t even want to go near them especially the wiring harness that controls the fan speed . That fan speed wiring harness has been a problem for these lochinvar knight boilers . Something in the harness shorts out periodically destroying the fan so you think it’s another bad fan , and it runs for a few days and the callback comes from a angry customer that her new 10,000 dollar heater is not working again. Check the bad fan assembly out and it’s sure as hell not working , I even inspect all of the harnesses and with the top Ang front covers removed from the unit I will reset the boiler with all the lights off and see if anything is arcing from that harness . That’s how I figured that problem out because lochinvar tech support wanted to put another fan assembly in which would make 3 in 2 weeks at 1200 bucks a pop . The first one will be covered under warranty but that’s it .
That heat exchanger needs to be cleaned better than the way you left it , they sell a kit with a nylon brush that you can use on the heat exchanger, if you don’t get all of that brown and green build up off of the stainless steel heat exchanger you will have a leak within 3 years .
Thanks for sharing your knowledge. Looks easy enough. Love my Knight boiler.
does the refractory ever need cleaning? if so, what's the procedure?
Can you use the board from armor to knight
Don't you have to clean the sock too?
Why is it so clean?
Probably just a demonstration boiler

I just walk in via gas precious
This was mildly informative. How about actually showing some useful procedures like cleaning the unit, or replacing worn refractors?
