7) Fill the Boiler to the lowest permissible water level (LPWL), at which all
firetubes are fully submerged in the water, and then pour in the concentrated
cleaning solution from the exposed tapping with its plug or safety valve removed in
step (4) above.
8) Replace the plug or safety valves, and close up other openings that may have
been opened.
9) Steam Boilers shall then be filled with additional water to the normal water
level (NWL, about 3-in or higher in gauge glass).
10) Water Boilers and the entire system may be filled with additional water up to
the expansion tank. To assure a full system, open all air vents until water is emitted.
11) Start the firing equipment, and check the operating limit and safety controls in
accordance with burner manufacturer’s service manual.
NOTE:
On cold light off the operator should be aware that a significant amount of
condensate could form in the firesides and become evident at the drains provided in the
smoke-boxes. This is normal and should not be cause for alarm.
12) Operate the Boiler as though in conventional service, reaching normal
operating temperature for water or normal pressures for steam. Maintain at low fire
until Boiler is warmed up to prevent thermal shock.
13) Steam Boilers should be operated for a few days to bring oil and dirt from the
system back to the Boiler. If desired, the condensate return may be discarded to
the drain and operation continued until the condensate runs clear.
14) Water Boilers should be operated for one day with pumped circulation
throughout the entire water system.
15) Stop the firing equipment.
16) Drain the Boiler and water system to a location that can safely handle hot
water.Be aware- of Local EPA regulations with regards to discharge of wastewater.
17) Use a high-pressure water stream to hose down the waterside of the Boiler.
18) Refill the boiler system with fresh water: steam Boiler to proper water level;
water Boiler to expansion tank, venting air as it is filled.
19) Bring water temperature up to at least 200 °F.
20) Add boiler water treatment chemicals as required.
21) Tighten man-hole/hand-hole covers and plugs while Boiler is hot.
