I have a Tempstar (made by HQ) furnace that is model number NUGK100DH03 with a serial number of L88… so I am guessing it is a 1988 furnace. I had a Lennox guy clean it and found out the burners were mostly rusted out. He told me he thought the furnace (100,000 btu’s) was way too big for my 1650sq ft house which is why the burners most likely rusted out. I am getting the replacement burners installed next week but the guy told me he also thought the pilot light should go out after the furnace turns off (once it reaches room temp for the t-stat). I asked the repair man to throw in a new gas valve (in the case the pilot is supposed to go out) but where can I verify this for sure since I dont have documentation on the proper functionality of my specific furnace.
I havent been able to find anything about this furnace, not even a manual that explains whether or not there is an automatic or standing pilot. I also would like to find out how efficient this furnace is. I was told it was probably 90% because of the PVC pipe but it would be nice to be able to verify this information from a manual or some other trustable source.
Also can anyone tell me what the fan shutoff is supposed to be set to for the CAMSTAT? it is currently set at 95 but the range is 90-130 (if I remember correctly).
