6.2.2 Fill heating system with water.
NOTE:
Anytime that raw water is introduce into the Boiler it must be heated to at least
180 degrees F immediately to dissipate the dissolved gases, which can otherwise cause
internal corrosion to the Boiler.
6.2.3 STEAM BOILERS – Fill Boiler to normal water line. Water should be visible in
the gauge glass. After Boiler is in operation, make up water should be added slowly to
maintain the water level.
6.2.4 HOT WATER BOILERS – 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.
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.
6.2.5 DO NOT draw water from Boiler while in use. When adding water while Boiler is
in operation, do not open supply valve fully but add water slowly.
6.2.6 ADJUST BURNER according to the burner manufacturer’s specifications. Refer to
burner manufacturer’s installation manual furnished with the Boiler.
6.2.7 TEST CONTROLS
WARNING!!
Before the installation of Boiler is considered complete, the operation of
the boiler controls must be checked, particularly the Low Water Cut-Off and High Limit
Control.
6.2.8 CHECK OPERA TING CONTROL OPERA TION. Raise and lower operating control
setting as required to start and stop burner.
WARNING!!
–
Check 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.
6.2.9 CHECK LOW WATER CUTOFF controls at normal water level. Run operating
control setting to allow burner to operate. Open boiler drain to allow water level to drop
to the bottom of sight glass until burner operation is shut down by low water cutoff.
Close the boiler drain and refill to normal water level. Unless Boiler is equipped with a
manual-reset low water cutoff, burner should automatically restart during fill. Reset
operating control.
