Step 6: Main Gas Shut-Off Valve Train; Step 7: Process Temperature Control System - Eclipse AH-MA DualBlock Design Manual

Flame Monitoring Control
The flame monitoring control processes the signal from
the flame sensor and controls the start-up and shut-down
sequences.
Eclipse recommends the following flame monitoring
controls:
• Trilogy series T400 (Instruction Manual 830)
• Veri-Flame series 5600 (Instruction Manual 818)
• Bi-Flame series 6500 (Instruction Manual 826)
• Multi-Flame series 6000 (Instruction Manual 820)
■ If other controls are considered, contact Eclipse to
determine how burner performance may be
affected. Flame monitoring controls that have
lower sensitivity flame detecting circuits may limit
burner turndown and change the requirements for
ignition.
■ Flame monitoring controls that stop the spark as
soon as a signal is detected may prevent
establishment of flame, particularly when using UV
scanners. The flame monitoring control must
maintain the spark for a fixed time interval that is
long enough for ignition.

Step 6: Main Gas Shut-Off Valve Train

Component Selection
Eclipse can help in the design of a main gas shutoff valve
train that satisfies the customer and complies with all local
safety standards and codes set by the authorities within
that jurisdiction. Contact Eclipse for further information.
NOTE: Eclipse supports NFPA regulations (two gas shut-
off valves as a minimum standard for main gas shut-off
systems).
Valve Train Size
Fuel pressure supplied to the ratio regulator inlet must be
in the value range specified in Datasheet 163. The valve
train should be sized sufficiently to provide the specified
pressure.
Step 7: Process Temperature Control
System
The process temperature control system is used to control
and monitor the temperature of the system. There is a
wide variety of control and measuring equipment
available. For details, please contact Eclipse.

CAUTION
Consult Eclipse
Eclipse can help you design and obtain a main gas shutoff
valve train that complies with the current safety standards.
The shut-off valve train must comply with local safety
standards set by authorized jurisdiction.

representative or Eclipse Inc.
NOTE: Eclipse supports NFPA regulations (two shut-off
valves) as a minimum standard for main gas "safety
shutoff valves."
