Maintenance
g) Remove brass pipe plug at the
cross connection below water column
and clean nipple into boiler. Boiler
must be cold and water level below
pipe.
Remove plug at cross section; clean
nipple to boiler.
Recommended Semi-Annual
Maintenance Schedule
a) Cleaning the gas burner
assembly
1) Disconnect the gas head from the
burner by disconnecting the union.
Remove the burner plate screws. For
4-15 HP boilers with scanner, discon-
nect scanner from burner plate.
Withdraw the burner assembly and
clean the flame rod and ignition elec-
trode.
2) Check that the settings of the
flame rod, if applicable, and ignition
electrode correspond to those in the
illustration below.
3) Reassemble the burner assembly
and check the flame rod setting or
scanner setting.
4) Check the combustion efficiency of
the burner and adjust if necessary.
5) Clean probe on top of boiler shell
and probes in water column. There
must be no pressure on the boiler dur-
ing the removal of the probes.
6) Check refractories for soot or
breakage and inspect the stainless
steel ring (50 and 60 HP only).
7) With the boiler under no more
than 15 PSI pressure, check that the
steam safety valve is operating by
lifting the lever.
b) Drain condensate tank and clean
tank by flushing with hose. Check
float valve operation.
c) Check electrical controls and
motors for correct operation.
d) Check water pump for correct
operation.
e) Shut off the boiler completely
and drain.
f) Remove the hand holes and
inspect the interior of the vessel for
scale or sludge deposits. The
amount of deposits will indicate the
efficiency of the water treatment being
used. The frequency of the inspection
will depend on the condition of the
water side of the boiler.
