High efficiency gas boiler keeps shutting down
in Gas Heating
Hi, thanks for reading. I had a MAC-205 installed 2 months ago and it hasn't stayed lit for more than 3 days. Weve gone through a bunch of things but I recently noticed that it calls for a 3/4 " gas line. i have a 3/4" line in the house but it comes from a 5/8" line, through a regulator, from my underground tank. Could this be an issue? Going from 5/8 to 3/4 into the boiler?
Yes. On the tank is a 5-10 psi regulator that the 5/8 line comes from. That goes into a Rego LV5503 which looks like its - Factory Delivery Pressure: 11" w.c. at 10 PSIG InletJUGHNE said:
Do you have 2 stage regulation for the LP gas supply?
The 3/4 line comes off that Rego. That same line has a T that feeds my water heater with a 1/2" line0
Without knowing the exact incoming standing gas pressure, operating gas pressure, O2, CO2, CO numbers. Everything at this point is a WAG. You will need a technician with the proper instruments to set up and fine tune the boiler.
The loss of flame is telling you to do the analysis asap. Have the tech. leave his analysis numbers with you and the boiler.
