FIRE FUEL SHUT-OFF (OPTIONAL)
Operating Instructions
A. Electric
Actuation of the fire control system per the
submittal drawing will trip all circuit
breakers and controls equipped with the
fire-fuel shut-off feature and deenergize the
corresponding outlets. After the fire control
system is returned to normal operating
conditions, these circuit breakers will be
de-energized until the circuit breakers are
reset.
B. Gas
Actuation of the fire control system per the
submittal drawing will stop all gas flow to
the gas operated equipment. After the fire
control system isreturned to normal
operating conditions, the button marked gas
reset must be pressed. This will reset the
gas system and gas will flow to all gas
operated equipment.
IMPORTANT NOTE: After the gas system
has been reset, all pilot lights must be
re-lit.
Gas 5-Second Delay (Optional)
This system is identical to the system
explained above; however, the gas system
will shut off in 5 seconds after the fire fuel
system is actuated. This system will prevent
nuisance pilot outages due to the
instantaneous power interruptions. With this
option, a GAS-OFF light and horn is
supplied.
Remote Status Indicator Lights
(Optional)
These lights are located remotely from each
Greenheck connection plate; however, they
are interconnected to each connection plate
and show circuit breaker ON or OFF status.
Ventilator Light Switch (Optional)
The ventilator light switch is located on the control panel. Be sure that the ventilator light switch circuit
breaker, which is located next to the light switch, is in the ON position.
