Main Components and Purpose Reference
Transformer
AT0E-2662-5
-Steps down the line voltage to approximately 24VAC
nominal
Timer, Ignition Fault
AT0E-2500-3
-Controls fault light.
-If signal is lost from the ignition module the timer
causes ignition fault light to turn on
Control Relay, 24vdc
AT0E-2625-6
-Controls input signal to ignition module.
-Coil side of relay is energized by digital control board.
Infrared Burner - Gas (36” & 48”)
AT2B-2099-2
-Supplies heat to the griddles steam chamber
- Supplies flame for flame sensor
Flame Sensor
AT2E-4717-2
-When in direct contact with the flame, the sensors gives
off a DC Millivolt or DC Micro amp signal to the
ignition module.
Igniter
A22E-4716-1
-Receives voltage from ignition module.
- Ignites burners. (1/8”-3/16” Gap)
Natural Gas Valve, 5” WC (H20)
AT2E-1806-2
-Regulates incoming gas pressure (1/2lb or 14”WC max
unregulated incoming pressure)
-First valve opens when control board is powered on and
the second valve opens and supplies gas to the burners
when the control board calls for heat.
Ignition Control Module
AT2E-1807-1
-Takes reading from the flame sensor.
-Receives input from temperature Controller and
Hi-Limit.
-Sends voltage to the igniter.
-Controls gas valve and heat lamp
Digital Control Board
AT0E-3625-5
-Receives input signal from RTD Temperature Sensor.
-Pulls in relay which controls the ignition module.
Fuse .75 Amp 250v
AT0E-2731-4
-The .75A fuse is to provide protection to the control cir-
cuitry in case of a short in the system.
Hi-Limit Control Board
AT0E-3880-1
-Receives input signal from Hi-Limit RTD temperature
sensor
-Cuts power to ignition module when unsafe signal
is met from Hi-Limit RTD (approximatively 425° or
182Ω)
Temperature Sensor RTD
AT0E-2885-8
(Black heat shrink sleeve for 1000Ω identification)
- The RTD provide temperature reference information to
the Temperature Control. This RTD is a 1000Ω.
Hi-Limit Temperature Sensor, RTD
AT0E-2885-7
(Red heat shrink sleeve for 100Ω identification)
- The RTD provide temperature reference information to
the Hi-Limit Board. This RTD is a 100Ω.
Heat Lamp 24v Red
AT0E-1800-2
-Receives 24VAC power from the ignition module and
indicates the valve is open.
