Arrived, greeted Jeff and proceeded downstairs to rip and tear out the old gas fired boiler. We turned off the power and bled the system dry. We cut the piping in varies locations to disconnect and remove the boil. We supplied and installed a new Crown 85% efficient gas fired boiler. We set the boiler on 4” pavers. We supplied all the pipe and fittings to install the following: extrol #30 expansion tank, Spiro vent air valve, expansion tank service valve, water feeder with a backflow preventer, boiler drain, 007E taco ECM circulator, etc, etc, etc. We plumbed and fitted all items according to manufacturer specs. We rerouted the wiring and rewired the boiler controls, system circulator. After the boiler installation was completed, we filled the system with water and checked for leaks. System pressure was good. We restored power, purged the gas lines and fired up the unit. The boiler fired, ran, cycled and reached temperature. All is good. The boiler is operating as it should.
