High-Effi ciency Gas
2-2
T
he closed burner and ignition system on 50 and 30lb high-effi ciency gas fryers work the
same. The fryers in the platforms shown here share a number of common ignition parts:
• Interface boards behind the controller hold relays that send 24VAC to the ignition system.
• Spark modules open the gas valve, create spark and check for fl ame in the burner.
• Blowers enhance the operation of the closed burner.
• Temperature probes in the frypot monitor oil via resistance and report back to the interface
board and then the controller display.
• Hi-limit probes open to prevent further heating if the oil becomes too hot.
The LOV and FilterQuick fryers have 30lb frypots and additional features for automatic
fi ltering and topoff. The OCF gas has 30lb frypots, automatic top off and prompted manual
fi ltering. Those features are described in more detail in an online course. However, the burner
and ignition system works the same as the earlier high effi ciency gas fryers. .
The problems that prevent any of these fryers from heating will be similar and largely the
troubleshooting techniques are the same.
The following pages show inside views of the cabinet and the control boxes of the high-
effi ciency gas fryers.
The cabinet interior of an Oil Conserving Fryer or OCF exhibits the same ignition
components as the 50-55, LOV and FilterQuick fryers.
