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.

i am still look to hear what type heaters you have. A brand or model number
would be nice but you can describe the things I list below and it will tell
what type systems you have.
1) Does it have selector switch for a fan to blow air into the room or not
2) Is there 120 volt electric service coming to it ?
3) When looking at the pilot lite does the thrmocouple look kind of fat
like 1/2" big around and about 2 ' long where the flame is suppose to hit it
or is the thermocouple small and thin like a thermocouple like a hot water
tank thermocouple ? I need to know so I can tell what system you have.
4) Is it fueled by Natural gas or propane / LP ?
5) On the heater that the pilot lite seem not to work. Will the pilot lite
ever light at all or just light and when you let go of the button the pilot
lite will go out. I need to know which it is.
6) Are these wall furnaces are in one unit with one side in one room and
the other in the other room ? Or they totally seperate systems in different
parts of the house?
7) Do they have a thermostat on the wall or control by a knob on the
heater it'self ?
8) Go out side and look at the Gas meter and see if the shut off valve for
the meter is open wide open ?
9) Does the gas valve have somewhere on it stamped ITT on it anywhere?
10) Look at the roof at the pipe for vent gas to leave the roof and see if
the vent cap is not mashed down and cutting the burn vapors off from coming
11) About what year was these heater made / bought / can be in blocks of
10 years like 10 , 20 , 30, or 40 years ago?
Here is your start!
