July 2nd installation-Straub

Paul, Luke and Zack were most efficient and were respectful of the fact that we are in a pandemic and wore masks when around us which we appreciated. DiBiase is most fortunate to have such capable employees, including Angie at the office.

Performed gas heat tune up check electrical low and high ok check filter, ok cleaned flame sensor and check burners, manifold propane pressure ok performed combustion test ok cycle furnace, noticed heater is a one pipe system recommend adding grill to mechanical room, currently does not have enough to supply combustion needs more air and by adding grill on mechanical room wall this will make up combustion air

Reclaimed and removed old equipment. Installed new leveled pad, disconnect, whip, And lineset. Brazed in with nitrogen. Placed new Amana high efficiency gas furnace on furnace feet and sealed coil on top. Brazed in with nitrogen and pressure tested to 300 then evacuated down to 221 microns. Ran new intake and exhaust vents across basement to outside wall. Ran new gas line to exterior. Was not able to test heating due to gas line not being connected. Installed new ez trap and condensate pump and wired safteys to break r. Installed new return and supply ductwork and relocated to left side of unit. Tested system in cool and adjusted charge. System working well at time of install.
