Dennis has supplied some good info on these. I see the occasional
spider or even dead fly in ours, and since I don't use it through
the summer, there's nearly always a little 'critter' to clean out in
the Fall. A byproduct of burning LP is water vapor, and this tends
to cause corrosion buildup, as well.
I use our pilot broaches alot, but they're pretty expensive. Years ago,
before I found them, I used a single 'thread' of stranded copper wire.
Lamp cord worked well on smaller ones, hi temp range wire strands
(nickle-plated) on larger. More fragile than a broach, but a lot less $,
and with a little patience, does a passable job. There's also less chance
of ruining an orifice by broaching it out too big, bc the copper won't
remove metal like a broach.
These heaters use pretty straight-forward control systems, but one
problem is finding parts, especially for older heaters. Some of the
brand names seem to come and go so fast it's really tough to find exact
Mine here in the shop/office is a good example - it's an 'Alvima', and
since I've had it for nearly 20 years, I'm not planning on repairs if it
unless it's something simple.
Anyway, hope that helps a bit. As far as publications on other appliances,
