Burnham FM01FD00B manual Test Controls

E.TEST CONTROLS

WARNING

Before installation of the boiler is considered complete, the operation of the boiler controls should be checked, particularly the low water cutoff and the high limit control.

1.CHECK OPERATING CONTROL OPERATION.

Raise and lower operating control setting as required to start and stop burner.

2.CHECK OPERATION OF HIGH LIMIT CONTROL.

Jumper operating control terminals. Allow burner to operate until shutdown by limit. Installation is not considered complete until this check has been made.

REMOVE JUMPER.

3.CHECK LOW WATER CUTOFF CONTROL Raise operating control setting to allow burner to operate. Close isolation valves in supply and return near boiler piping. Open boiler drain to allow water level to drop until burner operation is shut down by low water cutoff. If necessary, open relief valve for air to facilitate draining.

Close boiler drain and refill boiler. Burner should automatically restart during fill, unless low water cutoff control requires manual reset. Close relief valve when water flows out discharge piping.

open supply and return isolation valves.

Reset operating control.

CAUTION

Probe and float type low water cutoff devices require annual inspection and maintenance.

Refer to Section VI step (C) for proper cleaning instructions.

F.BOILER AND SYSTEM CLEANING (water side)

NOTICE

A qualified water treatment chemical specialist should be consulted for recommendations regarding appropriate chemical compounds and concentrations which are compatible with local environmental regulations.

WARNING

Chemicals used in treating boiler water are toxic and/or harmful. Always use protective clothing and equipment when working with/ near chemicals. Contact local authorities to determine if treated boiler water can be discharged into local waste water system.

1.Filling of Boiler and System --- General --- In a hot water heating system, the boiler and entire system (other than the expansion tank) must be full of water for satisfactory operation. Water should be added to the system until the boiler pressure gauge registers normal system design operating pressure. To insure that the system is full, water should come out of all air vents when opened.

2.Boiling Out of Boiler and System. The oil and grease which accumulate in a new hot water boiler can be washed out in the following manner.

a.Remove safety relief valve using extreme care to avoid damaging it.

b.Add an appropriate amount of recommended boilout compound.

c.Reinstall safety relief valve.

d.Fill the entire system with water.

e.Start firing the boiler.

f.Circulate the water through the entire system.

g.Vent the system, including the radiation.

h.Allow boiler water to reach operating temperature, if possible.

i.Continue to circulate the water for a few hours.

j.Stop firing the boiler.

k.Drain the system in a manner and to a location that hot water can be discharged with safety.

l.Remove plugs from all available returns and wash the water side of the boiler as thoroughly as possible, using a high-pressure water stream.

m.Refill the system with fresh water.

3.Add appropriate boiler water treatment compounds as recommended by your local qualified water treatment company.

4.Make pH or Alkalinity Test.

After boiler and system have been cleaned and refilled as previously described, test the pH of the water in the system. This can easily be done by drawing a small sample of boiler water and testing with hydrion paper which is used in the same manner as litmus paper, except it gives specific readings. A color chart on the side of the small hydrion dispenser gives the reading in pH. Hydrion paper is inexpensive and obtainable from any chemical supply house or through your local druggist.
