Oil Burner; Blower And Motor; Heat Exchanger - Thermo Products Spirit Series Installation, Operation And Service Manual

Oil Burner

NOTICE: A qualified heating contractor MUST service the oil burner in this furnace
at least once a year.
Generally, service to the burner will involve a thorough inspection and cleaning of the
burner, replacement of the oil nozzle and oil filter, and readjustment of the burner to
achieve proper ignition and clean combustion.

Blower and Motor

NOTICE: The fan motor has sealed bearings that do NOT require lubrication.
The blower and fan motor will not normally require any service. This furnace is equipped
with a directly-driven blower. Therefore, it will not require any retensioning or
replacement of a drive belt.

Heat Exchanger

c CAUTION: DO NOT attempt to clean the heat exchanger unless electrical power
and fuel flow to the furnace are turned off and the furnace is at room temperature.
c CAUTION: The combustion chamber refractory material is fragile and can be
easily damaged. If the inner radiator of the heat exchanger is cleaned, avoid
scraping or hitting the walls of the combustion chamber.
CAUTION: Do not brush or scrape the surface of the combustion chamber. It can be
easily damaged.
NOTICE: A qualified heating contractor MUST inspect the heat exchanger in this
furnace at least once a year. If heavy deposits are found, immediate cleaning is
required.
All heat exchanger surfaces should be as clean as possible for the most efficient
operation of the furnace. The heat exchanger may require cleaning after every heating
season, as combustion of fuel oil tends to produce soot, particulate matter, and scale,
due to corrosion.
NOTICE: Accumulation of heavy soot deposits over one heating season may
indicate the oil burner is out of adjustment.
The heat exchanger may be inspected and cleaned through an access, or cleanout, port
located in the burner compartment. Remove clean-out plugs, the vent connector pipe to
the chimney, the burner, and the burner mounting plates. When removing the clean-out
plugs, remove the screw at the 12 o'clock position. Then, pull clean-out plug straight
back.
