7. Valves
a) Pressure Gauge: the pressure gauge is above the panel box, which is installed
on the right hand of the boiler. A three-way valve is fitted with the pressure
gauge, to assist drain off regularly.
b) Main Steam Valve: the main steam valve is installed on the top of the boiler. It
will be connected with the steam pipe work to all kinds of equipment, which
consume steam. There should be enough outlet for drain off and flush in the pipe
work.
c) Safety Valve: the safety valve is installed on the top of the boiler. Its setting was
finished by the manufacturer before delivery; do not attempt to change the
setting. The function of the safety valve is to avoid pressure in the boiler from
exceeding the design valve. Any equipment connected with the boiler can run
under the boiler pressure. If not, another safety valve must be used to protect it.
CAUTION
The safety valve supplied by the manufacturer can only protect the boiler;
it cannot protect any other equipment in the system.
d) Water Level Gauge: the water level gauge is equipped to monitor the boiler water
level. The boiler operator can see the water level inside the boiler from these
gauges. Both of them are connected to a drain line for periodic flushing.
8. Electrical Requirements
a) Connect wiring as shown in the wiring diagram, which is furnished
inside the electrical control panel box.
b) Electrical power available is usually 230/460 volt, 3 phase, 60 HZ (in
USA), 3 phases, 50 HZ (outside USA).
9. Gas Supply
a) Natural gas is the standard gas for the gas boiler. Special
requirements on request- i.e. liquid petroleum gas, town gas.
b) Gas must be supplied at a pressure high enough to overcome the
pressure loss in the burner gas train and furnace while running at full
input. This pressure is different based on the burner used. The
pressure must be checked to make sure it is high enough. If it is too
low, a gas booster must be used in the gas supply system.
