We drained down the old boiler and removed the old system. We mounted leveled and piped in the new boiler install new ball valves and drains on the system. We ran out a new 3-in PVC flu pipe replacing the old 3-in vent. We wired the high voltage to system from the zone control plumber is going to change out the zone control and why are all the zone valves and thermostats. Hooked up and installed a new 3/4 gas flex and checked for leaks. Ran out new outdoor sensor. Need to return when they turn on the water from the street to the house to fill and purge the boiler then we can proceed with doing a startup and a combustion analysis test. Started boiler performed a combustion test changes curve he would like us to come back after everything is done with the plumber and just double check everything on the boiler
