AUTOMATIC
GAS VALVE
The Automatic Gas Valve opens or closes according to the
heat requirements
of the thermostat and temperature
limit
control. It closes if the pilot goes out. Each individual control
must be operating correctly before any gas can pass to the
burners. Any one control can hold the gas supply from burner
regardless of the demand of any other control.
SAFETY PILOT
Safety Pilot prevents the flow of gas to burner if the pilot
goes out, or will not ignite.
GAS VALVE SAFETY SHUTDOWN TEST
1. For boilers equipped
with continuous
pilot, with main
burners firing, disconnect the thermocouple from the gas
valve. The gas valve should immediately shut off the main
burners and the pilot.
2. For boilers equipped with intermittent ignition, with main
burners firing, disconnect
the ignition cable from the
intermittent pilot control box. The gas valve should shut
off the main burners. TURN OFF ELECTRIC POWER to
boiler before reconnecting
ignition cable, to prevent
electric shock.
RELIGHT
The electricand gasshall be offfor 5 minutesbeforerelighting.
THERMOSTAT
Keep it set at a desired room temperature. If windows are
to be opened or heat is not needed, move thermostat pointer
to a lower setting.
NOTE
In the event of failure of any component, the system
will not operate or will go into safety lockout. The system
is completely self-checking
On every call for heat, each
component
must be functioning
properly
to permit
operation. On safety lockout the system has to be reset
by turning the thermostat to the lowest setting for one
minute, then back to the normal setting.
Safe lighting and other performance
criteria were met with
the gas manifold and control assembly provided on the boiler
when the boiler underwent tests specified in ANSI Z21.13
- latest revision.
