During normal operation, the pilot flame is continually
monitored . The flame current signal must maintain 0 .15
microamps minimum . Flame failure response time is 0 .8
seconds maximum . If at any time the ignition module does
not detect a pilot flame, it will repeat the ignition process by
allowing a 50 second trial of ignition .
Figure illustrates this sequence of operation .

INSTALLATION
The instructions given for installation form part of the
delivery package . Anyone installing a chain griddle should
follow a strict procedure to make sure installation and
commission are safe, efficient and complies with the
applicable local codes . Here is a check list of things to do in
the order we recommend .
Mechanical
• Uncrate and check for shipping damage both obvious
and hidden . Write a damage report and report
immediately to the carrier .
• Check the serial plate behind the front panel . To do this,
remove the front panel by unscrewing the two screws in
the upper right and left corners . Next unscrew the two
fasteners securing the hinged lower font panel in place .
Note the burner inputs shown on the serial number
plate . It may be necessary to refer to these later . You also
need to be certain of the type of gas to which the unit
is connected . The serial plate also specifies the type of
gas required for the unit . Also, check that the electrical
connections are in good order .
NOTE
: The chain griddle is certified for installation on a
combustible base with minimum clearance of 6” (15mm)
back and 6” (15mm) sides from combustible walls .
• Every unit is fitted with a readily accessible shut-off valve
at the main manifold . Use a minimum of 3/” NPT pipe to
connect the incoming gas supply .
CAUTION
: Check the pipe capacity tables given in the
installation code . When a long supply pipe run is necessary,
you may have to install a supply line lager than 3/”
• Have a qualified gas technician check the gas supply to
make sure it will deliver the BTUs of gas the unit requires
to operate with no more than 1/” water pressure
drop . Also when making this check be certain that all
equipment on the gas line is turned to the ON position .
• If you are installing the unit using a new gas installation,
make sure the supply lines have been cleaned and
purged of piping compound, chips and other debris .
WARNING
: Use soap solution if you have to check the gas
lines for leaks .
• Place and install the unit on the legs or caters provided,
and make sure there is a minimum of ” (10mm) air
space below the unit for adequate air flow to the burners .
CAUTION
: Check for obstructions or objects that could
restrict the air flow to the burners .
• Using a spirit level variously across the front, rear and sides
of the unit, level it by adjusting the leveling legs .

NOTE
: For efficient operation, the griddle plate must be
level .
