Proper Flue Gas Venting
(This message could save your life)
NORDYNE furnaces are designed
with flue and vent systems that
direct flue gases safely out of
doors. You have nothing to worry
about as long as you have the
system maintained properly.
The flue and venting system should
be checked and cleaned every 12
months, or more frequently if you
suspect damage. This service must
be performed by a NORDYNE
distributor or Service PRO. DO
NOT attempt to perform this yearly
service yourself.
Convertible Firing Rate
The firing rate of your furnace may
be convertible using a certified
NORDYNE conversion kit installed
by a NORDYNE distributor or
Service PRO. See your installation
instructions for more details.
Oil Furnaces
The following should be performed
by a qualified service contractor at
least once each season.
* replace oil nozzle with type
specified for furnace.
* clean, adjust and replace, if
necessary, the spark
electrodes.

must be reset to factory
specifications.
* clean the inside of the furnace
heat exchanger and replace

TURNING ON YOUR HEATING
SYSTEM
Your Wall Thermostat
Responding to changes in room air
temperature, the thermostat
automatically turns your furnace on
and off to maintain the comfort level
you select.
Your thermostat is a sensitive
instrument. DO NOT expose it to
hot or cold drafts, direct heat
sources (sunlight, heat registers,
lamps, etc.) or areas where you
experience frequent wall vibration.
To save energy and reduce heating
costs, select the lowest comfort
level temperature appropriate for
your family. Set the thermostat 5 to
15 degrees lower at night and when
you are away from your home to
provide additional savings.

distributor about NORDYNE central
air conditioning. There’s an energy-
efficient, money saving, self-
contained unit designed for use with

open at both the fuel source
and at the furnace.
