These circuits are broken down into branch circuits of no more than 50 amps per circuit. A distribution lug in the BE Series and a copper bus bar in the BH Series is used to branch the power to individual fuses and contactors in each branch circuit. Each leg in each circuit is individually fused with fast acting fuses to interrupt power if required. -

Power is shut off to the elements until the modulating motor has driven the sequencer back to its original starting position. The relay is then activated, and the sequencer will bring the steps back on one at a time until the system is again balanced. There is also a limit supplied to be installed with the shunt trip on the main circuit breaker in order to completely shut down all power to the boiler. -

Assurance that the boiler is fed with only treated water at all times and that chemical treatment and blowdown procedures are always followed. Notification to the manufacturer (or manufacturer’s agent) to provide start-up services if the boiler was purchased with start-up by a factory representative. ... - Page 14 Before introducing the solution into the boiler, an overflow pipe should be attached to the top of the boiler and routed to a safe point of discharge. Remove all safety valves to ensure that none of the solution will come into contact with the valve seats.

Page 15: System Clean Out
3.3 SYSTEM CLEAN OUT Many boilers have been ruined with system contaminants such as pipe dope, cutting oil, metal shavings or chips and other debris which are left in the piping. If these contaminants are not removed, they will end up in the boiler. 3 . -
Page 16: Boiler Water Treatment
NOTE: For some old systems, there is a reluctance to clean the piping because of possible leaks occurring in badly corroded lines. Should the customer refuse cleaning, it is necessary to install filtration equipment. Install either a fibrous filter or a centrifugal filter in the boiler return piping. This will collect and remove sediment from the system. -

Page 23: Returning Idle Boiler To Service
Drain the boiler before the steam pressure falls to zero. Then pressurize with 5 psig nitrogen gas through a suitable top opening during draining. The nitrogen pressure is to be maintained through draining and subsequent storage. An alternate method is to completely dry a clean boiler (by blowing hot dry air through the boiler) and then purge the air from the boiler and pressurized with 5 psig nitrogen.
