    Furnace ready to go BOOM!

    I got called out to look at a Propane Furnace that hadn't been working for a few years, several other techs had been out on it, but none were able to get it to work. Name:  Furnace Ready to go BOOM.jpg

    Apparently one of the previous techs decided that it was okay to move the Flame Sensor to the burner with the HSI, guess it doesn't matter if the other 5 burners lite.

    And you’d better run solid pipe through the cabinet instead of the flexible gas connector.

    Its a 15+ year old install, so it was in code at the time. Any future replacement will get rigid pipe and a tee.

    I relocated the Flame Sensor back to the OEM Position and tried to start the Furnace, found only the top 2 Burners lite off.

    Checked the LP Gas pressure to the Furnace, found only 10.5"WC pressure inlet to the Furnace, but drops to 9"WC on startup. Also checked the Water Heater, found it had Low LP Gas pressure. Had the LP Regulator adjusted up to 12"WC and rechecked the Furnace.

    Found it now lite off 4 of the 6 Burners. Had to clean debris out of the Burner and now all 6 burners lite.

    Customer now has a reliable Heat source.

    This just shows the incompetence of some in the field. Definitely a way to gain a lifelong customer.
