The part in the picture that I posted, I call the gas valve. While everything wears out, that part doesn't see much wear and tear. If it works, then it will likely work for some time. As for failure points, I have seen torn diaphragms and broken thermostats. I am sure there are more types of failure.
If you find new old stock, please let me know. I would purchase a few spares. However, I think that is unlikely.
but none of the failures you speak of will lead to danger? i need to wake up .i looked on supply house .com they have a sku number 710-205 its a low profile combo gas valve. 1/2 inch by 1/2inch cost is 108.99 us dollars i wonder if that would fit mine. looks similar. heck david we are almost to the point of reproducing these unique heaters that we don't want anybody else to know about cause they are safe . reliable and unlike buddy heaters don't fume out. i still wonder why u want to see numbers on my gas valve i will try for you. its at my rv guy right now who is fabricating extension for the vent the tiontivv iualtn tto

Ummm.... That last sentence was kind of garbled. Were you going through a tunnel?

The only reason I want to know the model number of your gas valve is curiosity. Assuming it is not a model number I have come accross, it adds to the list of valves that I can use. So don’t go to heroic efforts to find out, though a mirror would probably make it easier.

Be careful of what gas valve you choose. There are several other, less expensive, Robertshaw gas valves that look exactly like the 710-201, but lack the thermocouple gas shut off feature, or something else. I have looked for a less expensive alternative, but found none. Either way the plumbing is different and would require someone with tube bending experience. That might be the most expensive part.

Probably the least expensive alternative is to find another furnace that uses the same valve. No guarantee that it works though. This is how I have an inventory of about 5 spare valves, one that is in pieces, and missing the large rubber diaphragm.

my data time was getting low on my computer so i needed to post what i had written sorry for the garble........I'm gonna hope that my gas valve will be ok.
i don't plan on doing winter in this hemisphere until I'm in an old folks home so i don't plan to use heater much if at all. maybe during fall a few times.
that's it. my rv guy is working as we speak he is waiting for some black tube part to get heater installed. thanks for all the info david i will try to get ou my gas valve number. from what i can tell my heater is not a model you have in your inventory. I'm gonna assume that since mine has a number two at end of numbers instead of one at end mine might be the very last model made before these things got banned. I'm curious david are you seeing these heaters in any junked out or old campers anymore. i would doubt it . as who would have a running heater like that in a camper from 1970 that still works. and if it did it would be in trashy condition. so any of these heaterss that are available now are from collectors or owners like you. why are these so unique? i think because they use no fan and are silent and safe if vented correctly

Actually, my 5 spare gas valves came from furnaces that I purchased on kijiji. Some were Duo-Therm furnaces, some were Coleman. I usually paid $50 for a furnace, but I have paid $100 for one that would fit my trailers.
