High efficiency gas boiler keeps shutting down
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?
