DANGER: The gas burner in this gas-fired equipment is designed and equipped to provide
safe controlled 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 that 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. Heaters installed in a confined space must be supplied with air for
combustion as required by Code and in Paragraph 9 of this heater installation manual.
MAINTAIN THE VENT SYSTEM IN STRUCTURALLY SOUND AND PROPER OPERATING
CONDITION.
10.0 Maintenance
and Service
When any service is completed, be careful to reassemble correctly to ensure
that no unsafe conditions are created. When re-lighting, always follow the light-
ing instructions on the heater.
10.1.1 Maintenance Schedule and Control Locations

9.0 Check Installation and Startup (cont’d)
The material contained in the MAINTENANCE AND SERVICE Section of this
manual is designed to aid a qualified service person in maintaining and servic-
ing this equipment. This heater will operate with a minimum of maintenance. To
ensure long life and satisfactory performance, a heater that is operated under
normal conditions should be inspected and cleaned at the start of each heating
season. If the heater is operating in an area where an unusual amount of dust
or soot or other impurities are present in the air, more frequent maintenance is
recommended.
