Furnace help

I have a hydroflame 79/80 in my 1996 Lance 11.5. It worked great last year before I unlocked her for the winter. I just put it back on and off course New England is not going to let go of cold nights. I need to get it workind get again.

The fan kicks on as it should. I have formed the instructions in the manual to a T with one exception. I do not have a valve that I can turn on and off on the gas line.

A I can assume is that this is some sort of automatic valve system that flows fuel when it needs to.

I get no ignition in the furnace athe all.


If anyone has any suggestions I am open. To almost anything.

Thanks

    Also if you are not plugged into 120 AC and your battery is low, the fan in then furnace will not run fast enough to activate/close the sail switch.

    Also - have you tried lighting your stove top burners? It will verify that you actually have propane gas and it will also tend to clear out air in the line which might otherwise prevent your furnace from starting.

    Lots of threads on this subject in this forum. I know, I started one a couple of months back. My heater was acting the same way, it turn out to be the circuit board. The sail switch and circuit board are the two most common problems with heaters.

    A sail switch is located near the squirrel cage. When the cage rotates the airflow causes a little sail like arm on the switch to move and close the switch. When the switch is closed the gas valve is then allowed to open provided all else is well.
    I think the service manual for your furnace is located at

    If not look through

    and see if the right one is listed
