DANGER
The gas burner in this gas-fired equipment is designed and equipped to provide
safe, complete combustion. However, if the installation does not permit the burner
to receive the proper supply of combustion air, complete combustion may not occur.
The result is incomplete combustion which produces carbon monoxide, a poisonous
gas that can cause death. Safe operation of indirect-fired gas burning equipment
requires a properly operating vent system which vents all flue products to the
outside atmosphere. FAILURE TO PROVIDE PROPER VENTING WILL RESULT IN A
HEALTH HAZARD WHICH COULD CAUSE SERIOUS PERSONAL INJURY OR DEATH.
Always comply with the combustion air requirements in the installation codes and in
Paragraph 2.2. Combustion air at the burner should be regulated only by manufacturer-
provided equipment. NEVER RESTRICT OR OTHERWISE ALTER THE SUPPLY OF
COMBUSTION AIR TO ANY HEATER. Indoor units installed in a confined space must be
supplied with air for combustion as required by Code and in Paragraph 2.2 of this heater
installation manual. MAINTAIN THE VENT SYSTEM IN STRUCTURALLY SOUND AND
PROPERLY OPERATING CONDITION.
 Close all panels tightly. With the heater on, check limit control by completely block-
ing off distribution air. The limit control should open within a few minutes, shutting
off the gas supply to the main burners.
 Place "Literature Bag" containing Limited Warranty Card, this booklet, and any
optional information in an accessible location near the heater. Follow the instruc-
tions on the bag
10.0 Maintenance
and Service
WARNING
If you turn off the power supply, turn off the gas. See Hazard Levels,
Page 2.
This unit will operate with a minimum of maintenance. To ensure long life and satis-
factory performance, a furnace that is operating under normal conditions should be
inspected every four months. If the furnace is operating in an area where an unusual
amount of dust or soot or other impurities are present in the air, more frequent inspec-
tion is recommended.
The following procedures should be carried out at least annually (See Para-
graphs 10.2.1- 10.2.4 for specific instructions.):

Clean all dirt and grease from the primary and secondary combustion air openings.
 Check the gas valve to ensure that gas flow is being shutoff completely.
 Clean the heat exchanger both internally and externally.
 Check the pilot burner and main burners for scale, dust, or lint accumulation. Clean
as needed.
 Check the vent system for soundness. Replace any parts that do not appear
sound.
 Check the wiring for any damaged wire. Replace damaged wiring. (See the wiring
diagram for replacement wiring requirements.)
CAUTION: When cleaning, wearing eye protection is recommended.
NOTE: Use only factory-authorized replacement parts.
