Lanair MX250 fuel PSI
« on: February 21, 2020, 05:39:26 pm »
Lately I've had to run my fuel pressure up around 8/10 lbs. Furnace runs but tends to not fire without manual reset most of the time, then it tends to short cycle. Fire several times, then the blower finally comes in. Some times it will go all day, or night. Sometimes it goes one, or two cycles. Anyone have a nay tips?
