8.5.6
CLEAN BLOWER ROTOR
If dirt or lint is allowed to accumulate on the cupped side of the blower rotor blades, shortage of air to the
burner will cause reduced burner efficiency. The frequency of cleaning will depend on the amount of dirt or
lint in the air at the particular installation.
To clean, remove nut and remove blower inspection cover. Insert the curved end of the cleaning tool under
rotor blade
(fig 7.1)
and move the tool back and forth until the entire under surface of the blade is cleaned
Repeat on all blades. The volute pressure, at high fire, is a good indicator of blower condition
(if no change
in damper adjustment has been made).

7000
hours operation.
•
Inspect all air, fuel and water control linkages
(where applicable)
for wear, screws tight, free
movement, etc...
•
Test steam safety valve(s)
[30]
. Set steam pressure parameter and limit pressure switch
[F21]
to
exceed steam relief valve pressure setting. Allow pressure to increase
(by throttling discharge valve)
until steam safety actuates.
WARNING
:
If valve does not actuate, after exceeding pressure setting, open steam
discharge valve immediately
The operation and setting of all alarm and operating switches, as well as setting and
operation of safety and relief valves should be checked by a qualified Clayton technician
