Maintenance
Procedure for Cleaning Water
Probes - (Recommended as
Annual Maintenance)
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, 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
adaptable 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 = 11-1/2” -- 286 mm
D = 17-1/8” -- 435 mm
*For 4 HP boilers only, water col-
umn probes are 2” (51 mm) shorter.
NOTE
For proper removal use 7/8”
socket.
