Wrong part
Have installed this brand of boiler for years. Supply house did not stock this model set up for propane gas. The person I talked to on the phone recommended a LP conversion kit so I ordered. The kit sent was for a standing pilot unit not spark ignition. Supplyhouse did not have the needed kit but provided me with the part number to source it out to someone else plus they are letting me return the wrong part. Great company!

Great Boiler!
This boiler was a direct replacement for the 40 year old weil mclain boiler I had. Fitment was super simple. I installed myself and saved a ton of money.

1 Question1 Question
Q: Is the water inlet/outlets on the right side or left side (when facing the front of unit) ? And does it come with or need an electric damper on the vent?

Verified Reply- SupplyHouse StaffHi Ed. The supply connection is on the top left of the boiler when facing the front of the unit, and the return connection is on the left side. It includes a 6" vent damper.
