Seeking Blaze King Thermostat Coil Information

[lp9900]

Hello, I have an older Blaze King wood stove insert (non-cat) = approximately 1982. I believe it may be the KFF-402. The thermostat coil had an L leg shape that slipped into the end of the second rod that controls the air damper. Somewhere along the line, the L part broke off so the coil is no longer attached. I can't find the part anywhere to replace the coil. Furthermore, it seems that the rods might need to be tensioned properly upon replacement? Unclear about this part. Can I simply remove the coil and bend a new L in it and put it back on? Or, would that throw off the thermostat specifications?

I'm sorry if these are basic questions. I would really love to continue to keep using my old trusty Blaze King, but the air intake is not adjustable since the thermostat coil broke. I can, however, move the rod manually with a tool, but that kind of defeats the whole purpose since it's meant to adjust by the heat.

Any ideas or input are greatly appreciated. I know this model is obsolete, but I don't have $5000 for a new unit and don't want to throw in the towel over a coil.

Have you called BK support to see if there is a replacement coil?

I’ve called and they said the parts are no longer available. I pretty much figured that. I am also trying to figure out the specifications of the coil and tension. In other words if I modify the coup to dig does that change everything. I think so.

Yes, I can understand your thinking. I would probably do the same. It will change the calibration, but that might be better than losing that control. However, be careful if you 'modify the coup to dig'. That's a whole nuther issue.

Remember that one of the things that coil and rod were set up for is to prevent overfires. If you modify the coil, the stove no longer has that top end protection (or conversely, maybe it can't burn hot at all).

If it was me I think I would start by drilling the broken pieces and using a couple tiny machine screws and a piece of steel strap to reconnect them, if that's possible given what you have to work with.

@BKVP : Any chance of a kff-402 thermostat and calibration procedures in a desk drawer somewhere?
