Fan Inlet Pressure
I. Lubrication. There are no parts requiring lubrication
by service technician or owner. Circulator bearings are
water lubricated. Blower motor bearings are factory
sealed.
J. Procedure for measuring fan inlet pressure. See
Figure 21.
1. With boiler off, remove hoses at pressure switch.
2. With tee connect water manometer as shown with
additional tubing.
3. Start boiler and read Pressure on Manometer
when boiler water temperature reaches operating
temperature. Refer to Table 12 for minimum
readings.
NOTE: If switch drops-out before boiler reaches
temperature or if inlet pressure reading is below
minimum shown in Table 12, check for cracks
in hose or contact your nearest New Yorker
representative.
4. Stop boiler, remove manometer and reconnect hose
to pressure switch.
