motor wiring, or replace the fan belt. Finally, restore
power to the furnace.
E) Operate the furnace through a minimum of three full
heating cycles. During this time, check for fuel oil leaks,
gross air leakage from the supply air ductwork, unusual
noises originating anywhere within the heating system
which may cause some concern or annoyance to the
home owner, etc.
F) Be sure that the homeowner is familiar with the
furnace. The homeowner should be aware of the location
of electrical circuit breaker or fuse, the location of any
electrical switches controlling the furnace, the location of
the oil tank shut-off valve and how to operate the valve.
The homeowner should know where the oil tank gauge is
located and how to read it.
It would be beneficial to review safety issues with the
home owner, such as the danger of storing combustibles
too close to the furnace, hanging anything on the furnace
vent pipe, and especially the dangers of indiscriminately
pressing the burner reset button.
IMPORTANT
: Be sure that the home owner knows where
the burner reset switch is located, and is aware that the
reset switch is not to be activated more than once without
a look for the cause of the problem, (lack of fuel, etc.). Be
sure that the homeowner knows when to quit trying to
start the furnace during these conditions and who to call
for emergency service.
