Looking for a part for Arstrong hanging furnance

[semi75]

I picked up an older Arstrong Air uhpa90 hanging furnace that I plan to try installing next week but the circuit board box cover is missing. I tested the unit and so far it seems operational. The box is 8x12 with three knockouts on the top. The closest thing I can find is a cover on a ADP sep100(Cayenne) but the size isn't listed.

I just can't seem to locate a junction box cover like this one or find parts specific for this unit's housing. The rest of the parts are your usual generic Honeywell gas valve, standard motors, ignitor, flame sensor etc.

My other not related question is installing the unit before spray foam insulation. I'm pretty sure that is the route I will go, it is a 30x40 metal pole barn with 13.5 sidewalls, open cieling. It just seems to make sense to run the gas line and run the vent pipe before insulating.

Semi that cover is easy enough to make with a small piece of sheetmetal no problem. I would do the install first especially if your doing spray foam so you dont have to cut through the foam after its in .

Thanks Rick. That's my plan if I can't find one. It would be easier if it were wood, my metal bending *****. Then again it doesn't have to be pretty. One would think it would be a fairly easy thing to find.

Semi all you need is a flat piece of metal with 2 90* bends to wrap around the sides . The good news is if you play with wood you probably already have what you need to bend the 90's on the metal . Take 2 pieces of scrap 2X4 set them in your vise and you can bend the 90's with them using your thumbs to carefully form the 90.

Thanks Rick, I have no idea why I didn't think of doing it that way. I was just going to clamp it to my workbench and bend it over the side, which usually results in a dent near a clamp. Sometimes common sense escapes me.

Hey Semi no problem . Honestly I was watching Stacey Davids Gearz on speed and had just watched him do exactly what I told you to do . I have sheetmetal breaks and such here as I do HVAC .
