“ The Venting does not meet the minimum required length to go out side? It is vented in PVC so it looks like it goes outside right behind the boiler and the minimum length is 12' with a 90 equaling 5 feet you still need 7 feet of pipe if it goes up a Chimney or alcove it should be CPVC. ” --tito
“My 3 year old Ultra 105 just catastrophically failed after three years in service, with a cracked heat exchanger. Weil-McLain does not have the part anywhere, including at their facility, so now I am stuck with no heat and no hot water in the middle of a Minnesota winter for 6+ days while I wait for their factory to MAKE the part and then ship it to me at my expense. And If I'm lucky, I might...” --bawa
“ This has been very easy to install and working unit for the last few year outside of the need to replace the nozzle which was only stocked on the east coast at the nozzle maker and I live in the midwest. ” --darestc
“ Had this installed 5 months ago in October 2010 in cold winter Canada. Two story house with basement so three heating zones, Has handled the cold weather no problem. Wall installation has freed up much floor space in utility room. Very quiet compared to the large1978-ish boiler I had before. Have no doubt this unit will pay for itself over the long term. Installation took longer than...” --Gruberman
