Heat Relays
Heat relays operate on 12 volts DC from the
controller. The relays are dual-pole/dual-throw and
switch both the 24 VAC to the ignition/gas circuit
and 120 VAC to the combustion fan motor.
The relays are removable, which allows inspec-
tion and testing.
Use caution when installing. There is no stud to
prevent upside down placement, which damages
the controller and the interface board.

Different Spark Modules
The style and brand of ignition module has changed
over the years. Honeywell units are the current mod-
ule and the most frequently used. Capable Controls
modules were introduced in December of 2014 and
stayed in use until December of 2015.
Capable Controls doesn't produce a dual-spark
module and the units have a different fl ame sensing
specifi cation.
Capable Control modules and Honeywells are inter-
changeable. Replacing a Honeywell with a Capable
Control requires a kit.
Fenwal modules were introduced in 2017 for use in
the 30-lb fryers.
