Piping as far as noise, etc has been fantastic as has been heating/comfort and the life of the circulator pump.
Would the flame sensor be an issue since we don't even get to a flame.....the fan comes on, but the purge does not finish, so the ignitor does not come on. I was wondering if we could have another bad fan switch?
By the lower tube for pressure sensor, you must mean the tube that goes from the air proving switch down into the burner chamber and clips onto one of the burner tubes (to measure air pressure in burner chamber)?
