Fuel Oil Furnace, maintenance basics
QUESTION:I have a Fuel Oil Furnace heating my house.
... 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?
ANSWER: You need to call a licensed HVAC Contractor with techs that do a lot of
service work on oil furnaces!
