We just installed a new boiler and Toyo OM-148 water heater. The boiler is shut down for the summer. When the OM-148 fires we are smelling fumes in the surrounding area. It is a brand new installation with new flue pipes. The unit works great and produces hot water as designed, but the fumes are a problem. Any suggestions on what I need to check or repair? We live in a remote area of Alaska where contractors are difficult to come by. Thanks!
