We just installed a new Peerless GM-07 boiler in an ambulance squad building, about 3,000 sq ft. This unit replaced a slightly smaller (300,000) peerless boiler that was about 45 years old. This is a gas hot water system with three zones that has three separate circulator pumps. The install went fine and the system heats well. My question is this, when the boiler fires, I hear what sounds like water dripping onto a hot surface. This sound continues while the boiler is heating and stops when the boiler shuts off. I checked the burners to see if that was where the water was dripping, but that looked ok. Could this be condensation from the flue gasses? The manual talked about if the supply water was less than 130F that we should loop it with the return water. The limit on the boiler is set at 180f and the water pressure is about 15lbs hot. Any help or suggestions would be appreciated.
