... or NOT heating the house.
I did service/maintain a fuel oil furnace back in the 70's for several years.
I am now needing to maintain/service this fuel oil furnace, but do not remember enough to feel competent to simply "tear into" the furnace.
What I am looking for, is: a pictorial exploded view of the working parts of the furnace (electrodes, nozzle, combustion chamber, transformer, etc.) and proper positioning/settings/condition of those items ... and how to properly effect such optimum conditions.
I just don't want to create more problems than I already have.
Problem: Furnace will fire up .. flame, upon call by thermostat, however: less than a minute later the flame goes out ... and the "reset" switch pops out. Upon resetting the reset switch, the furnace will again fire up (flame ... for less than a minute) and flame will go out ...
of course ... flame goes out when fuel pump/blower stops pumping fuel into the furnace
..........I pulled the stack temperature switch from furnace; it was free of soot, looking very clean.
I flipped open the door to view the area close to the combustion chamber ... it is quite sooty.
??? What do I need to clean? How should electrodes be oriented? (an earlier furnace had pictures and spec's, but I don't have that info with this furnace) How do I properly access the area needing serviced?
