The problem: Our furnace will turn on when set and then sporatically turn off and stay off for a couple hours before turning back on. Our furnace has a safety mechanism, where if it doesn't get the gas to lite after 3 attempts, it will shut-off for 2 hours. My theory is that when we use another appliance or fixture that pulls gas, like the tankless water heater, it is starving the furnace which shuts it down. When we bought the house, there was a meter at the entry with 2 split lines coming from it into the house. meter by Trent C posted Jan 16, 2020 at 7:36 AM We were told we probably didn't need it and could remove to clean up that area. So we had it removed and just split the line straight from the shutoff valve into the two lines going into the home. no meter by Trent C posted Jan 16, 2020 at 7:36 AM Could the meter(if that's what that was) have been regulating the gas to keep constant flow to furnace while supplying gas to hot water heater as needed? should we install some fixture to regulate at this entry or should the furnace be getting a constant flow in this set up? any help is appreciated.
