WHAT IS A CHAIN GRIDDLE continued
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 2 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” (152mm) back and 6” (152mm) sides from combustible walls..
•Every unit is fitted with a readily accessible
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 3/4”
•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 1/2” 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 4” (102mm) 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..
Gas Supply
NOTE : For efficient operation, the griddle plate must be level..
