10) Apply a moderate amount of good quality pipe dope to the pipe threads on the
probe, leaving the two end threads bare. Do not use PTFE (Teflon) tape.
11) Screw the probe into the boiler tapping.
12) Mount the low water cutoff control on the probe.
13) Reconnect the control to probe wiring.
14) Fill the Boiler to its normal waterline.
15) Add boiler water treatment compound as needed.
16) Restore electric service to the Boiler.
17) Fire burner to bring the water in the Boiler to a boil to drive off free oxygen.
WARNING!!
Before returning Boiler to service, follow the low water cut-off check
procedure.
5.6.2 FLOAT TYPE LOW WATER CUTOFF – During the heating season, if an external
low water cutoff is on the Boiler, the blow off valve should be opened once a month
(more frequently where conditions warrant), to flush out the sediment chamber so the
device will be free to function properly.
Low water cutoffs and water feeders should be dismantled annually by qualified
personnel, to the extent necessary to insure freedom from obstructions and proper
functioning of the working parts. Inspect connecting lines to Boiler for accumulation
of mud, scale, etc., and clean as required. Examine all visible wiring for brittle or worn
insulation and make sure electrical contacts are clean and that they function properly.
Give special attention to soldered joints on bellows and float when this type of control
is used. Check float for evidence of collapse and check mercury bulb (where applicable)
for mercury separation or discoloration. DO NOT ATTEMPT TO REPAIR MECHANISMS
IN THE FIELD. Complete replacement mechanisms, including necessary gaskets and
installation instructions, are available from the manufacturer.
a) CHECK BURNER AND CONDTROLS at least once a year. See operating
Instructions for control checks. See Burner Manual for burner tests and
adjustments.
b) LUBRICATE BOILER COMPONENTS according to manufacturer’s instructions.
Generally, this involves the burner and circulator. This includes the type of lubricant
to use, frequency of lubrication, and points to lubricate.
c) CHECK SAFETY VALVE at the start of each heating season and once or twice
during the season to be sure it is in working condition. To do this, fasten wire or cord
to lever of valve and pull lever standing a safe distance away from valve.
