DANGER: The gas burner in this direct gas-fired system 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.
Always comply with the combustion air requirements in the installation codes and operating
instructions. The amount of air over the burner must be within the specified range. The burner
profile plates are set at the factory to match CFM requirements. Do not adjust the burner
profile plates without contacting the factory. FAILURE TO PROVIDE PROPER COMBUSTION
AIR CAN RESULT IN A HEALTH HAZARD WHICH CAN CAUSE PROPERTY DAMAGE,
SERIOUS INJURY, AND/OR DEATH. Direct-fired installations should provide for air changes
as required by the applicable installation codes.
This direct-fired makeup air system is designed to require only a minimum
amount of maintenance. Some maintenance procedures outlined in this Sec-
tion require inspection only and some require action. Frequency requirements
of each maintenance procedure are listed in the Maintenance Schedule. De-
pending on the environment and the number of operating hours, more fre-
quent inspection and/or cleaning may be required to certain components.
Although maintenance requirements are minimal, the routine maintenance pro-
cedures in this Section are necessary to ensure safe, reliable, and/or efficient
operation. The paragraphs which follow discuss the components and systems
that require routine inspection/maintenance. At the beginning of each para-
graph, there is a code indicating why that maintenance procedure is necessary.
The legend for that code is shown on the left.
Maintenance
Schedule
The blower, motor and drive components are located in the blower cabinet.
Remove the panels required to access the component(s) being serviced.
1A. Blower Bearings
All blowers are Class I with pillow block bearings. Clean the fitting and add
type NLG-2 or -2 standard grade grease. Add grease with a handgun until a
slight bead of grease forms at the seal. Be careful not to unseat the seal by over
lubricating.
CAUTION: If the blower is unused for more than three months, the
bearings should be purged with new grease prior to startup.

WARNING: Disconnect all power to the system before doing
any maintenance. Failure to do so may cause electrical shock,
personal injury, or death.
