Furnace gas valve

My furnace is an older hydro flame 8531-II. the gas valve is not functioning so I was going to order a new one. But it appears that part number 31155 is no longer available. Does anyone know if the gas valves are more or less the same? I found one that looks similar except the propane inlet fitting is on the side rather than the back. Mine actually has a couple of fittings that connect to the propane line in the side. So I’m wondering if this alternate part would work.
  • In the photo of mine it shows the inlet down low on the "side" that connects to the gas line from the propane tank. Inlet is pointing to the right when looking at the furnace from outside the rig where the control board is on the far left.

    The burner on mine is turned 90 degrees the other way from the panther link's diagrams (three versions in their third photo). I suppose you can just turn that as needed.

    "Note there are three versions of gas valves that are applicable to the models listed below. Prior to ordering, please compare the picture of the valve to your existing valve to ensure that you are ordering the correct gas valve. If you have a 31096 or 31097 gas valve, you must order the 31155 and transfer the fitting, coil harness and the gas manifold from the old unit."

    I have a photo of either the II or III's with some other parts-burnt out burners etc. That shows how the gas valve is in a II or III (same). Not sure what is meant by "side" in the OP



    What I mean by “side” is…if I assume the gas outlet feeding the burner is the “front” of the valve, then the gas inlet is on the rear of the valve feeding straight through. However, mine also has a 90 degree fitting and then a short “S” fitting at the inlet so that the gas line actually enters the furnace box from the side. The replacement gas valve shown in your Panther link is the one I was looking at with the inlet on the side where my gas line enters the furnace box without the two fittings I mentioned. It looks like it should work but I figured I’d ask before I blew anything up.

    yep. Already did that. Every single one of those leads said that it is either no longer available, back ordered, or something along those lines. The only one that said it was available was some auto dealer up in Canada that linked through Walmart.ca. I actually tried ordering there but said my address wasn’t valid…I took that to mean they weren’t shipping across the border.
