5.2 Preventive Maintenance
Proper maintenance schedule and record keeping is critical for optimum
performance and to maintain the HARSCO Industrial, Patterson-Kelly
warranty.
The blower motor is permanently lubricated and does not require periodic
lubrication.
5.2.1 Daily Preventive Maintenance
Observe operating temperature and general conditions. Make sure that the flow of combustion and intake air
to the boiler are not obstructed. Determine the cause of any service codes or lockouts on the display panel.
Observe any unusual noises or operating conditions and make the necessary corrections. Notify responsible
individuals for required corrective action or repair.
5.2.2 Weekly Preventive Maintenance
Observe the conditions of the main flame. A normal high fire flame is mostly orange with a blue halo, while at
low fire the burner will glow yellowish-orange.
Correct air adjustment is essential to the efficient operation of this boiler. Ensure that the flow of combustion
and ventilation air is not obstructed.
If an adjustment in the combustion appears necessary, the flue gas composition should be checked with a
