Maintenance
NOTE
To ensure the continued safety and
efficiency of the boiler, the sched-
ule of maintenance outlined in this
section should be adhered to.
WARNING
Prior to the commencement of any
work requiring the removal of cover
plates and the opening of the con-
trol panel box, the electrical supply
to the boiler must be disconnected.
Procedure for Cleaning Water
Probes
Clean probe on top of boiler shell
and probes in water column. Make
sure there is no pressure on the
boiler during the removal of the
probes. Remove one probe (using
a 7/8" socket), clean with very fine
emory cloth and replace it before
removing another to assure no
probe mix-ups that would change
the control functions.
For replacement purposes, installed
probe lengths are indicated in the
chart below. For a universally adapt-
able plug and probe which can be cut
to length in the field to fit all boilers,
order Part No. 2-20-017.
*A = 7-1/4” -- 184 mm
*B = 9-1/4” -- 235 mm
*C = 11-1/4” -- 286 mm
D = 17-1/8” -- 435 mm
*For 4 HP boilers only, water column
probes are 2” shorter.
