The burner on my Burnham V-1 was experiencing some delayed ignition and, at times, wasn't firing at all. I figured I'd replace the nozzle and clean out the soot. I got a lot of it out, and have more to go, but the hot, moist weather is causing a lot of condensation which makes the job even more unpleasant than it usually is. So, the job is on hold till things cool down and dry out a bit.

Cleaning the fallen soot and gunk out of the combustion chamber destroyed the bottom liner and, of course, the molded insulation behind the front access plate came out in pieces. I have received a replacement liner kit that I'll put in, once I've got the cleaning done. But I noticed that the target wall liner in the boiler is of a rigid, foam-like material, while the one in the kit is a soft pad. Anyone know how come the difference?

Actually, the target wall liner seems to be in fairly decent shape - just a little stained - so, if I don't ruin it in the rest of the cleaning, I'm tempted to not replace it and just do the bottom and front. Would that be a bad idea? (That soft target wall liner looks like a pain to hang and keep in place.)

 

It would be a good idea to replace the blanket. If the front insulation is OK you may not want to replace it either. There is three separate pieces the Target wall (rear) the blanket and the front piece.

 

Thanks.
Further inspection of the kit revealed that the new target wall liner is actually moist and sort of moldable. The instructions say that it cures with firing. That pretty much clears up what I couldn't figure out.
