SECTION 5: OPERATION INSTRUCTIONS
NOTES
1) All tests MUST BE conducted by qualified personnel under the direct control of a qualified
supervisor.
2) Refer to burner manufacturer’s Installation, Operation and Maintenance Manual furnished
with the Boiler for proper venting of the gas train components that require atmospheric air
pressure to balance a diaphragm.
3) It is the responsibility of the installing contractor to see that all controls are correctly
installed and are operating properly when this installation is completed.
4) Always inspect installation thoroughly before starting burner.
5) Fill system with water.
CAUTION!
Anytime raw water is introduced into the Boiler it must be heated at least
180 °F immediately to dissipate the dissolved gases, which can otherwise cause internal
corrosion to the Boiler.
5.1 BoilerOperation
Water level must be maintained in the Boiler with strict compliance to the ASME Code.
5.1.1 Section I (High-Pressure) Power Boilers – Top of lower gauge glass nut (lowest
visible water level) must be located 3-in above the top of the highest firetube projection.
5.1.2 Section IV (Low-Pressure) Heating Boilers – Top of lower gauge glass nut (lowest
visible water level) must be located 1-in above the top of the highest firetube projection
where the Lowest Permissible Water Level (LPWL) tag is aligned to.
WARNING!!
On a hot water system the pressure must not exceed 30 psig, unless the
Boiler is especially designed for a higher working pressure. If boiler pressure exceeds the
pressure setting of safety relief valve(s), valve(s) will relieve immediately. The cause of
relief must be investigated and corrected. Excess pressure is dangerous and can cause
damage to the heating system, personal injury and serious property damage.
5.1.3 The water level in Boiler will be maintained by a water level controller, if the Boiler
is equipped with this type of control. The valves at the top and bottom of the water
gauge glass must be kept open so that true boiler water level will show in the glass.
5.1.4 Care must be taken to insure that the steam and water equalizer lines to the
water column and controller are kept clean and free from fouling. These should be
‘rotted’ out at least on an annual basis and be blown down with a frequency as dictated
by water quality.
