• ACL 5500 controller c/w mounting hardware
• ACL M-50A pilot mixer & nozzle
• 10' ground wire
• 10' high voltage wire complete with connectors
• 6.5' non-metallic flex complete with connectors

• Speed control valve
• ½"conduit seal
• Flame current test leads
• Operator's manual
The ACL 5500 can be mounted in a Class I, Div 2 area; usually close to the
burner. The 10' of high voltage lead, (longer length not recommended) must be
run in the non- metallic flex (provided) or free air. If the high voltage lead is run in
the non-metallic flex, a conduit seal (provided) must be installed. Note: Lead
length in excess of 10' or use of metal or metallic sheathed conduit may result in
a diminished ignitor rod voltage. A ground wire (also supplied) must be
connected between the ground lug on the burner assembly and the bonding
ground terminal on the main circuit board.
mounted farther away from the burner assembly, the ignition module, which is
mounted on the main circuit board, may be mounted in or near the burner
housing using the optional, CSA approved, ACL 5000R remote mount kit.

damage sensitive components.
application at least one of the ignition modules must be remotely mounted as the
controller housing will not accommodate two ignition modules. (Dual Burner kit
needed for dual burner applications)
The ACL 5500 is available in 12/24 VDC and 120/240 VAC. Voltage
requirements must be specified when ordering. The supply voltage of each unit is
clearly marked inside the door on the specification label and on the circuit board
beside its respective terminal.

or system ground and the terminal marked bonding ground is strictly for the
ground wire to the burner assembly. It is important that a ground wire (supplied)
be connected between the bonding ground terminal and the burner assembly to
provide an uninterrupted path for the flame acknowledgment current.
There are four solenoid output terminals on the main circuit board marked pilot
solenoid and main solenoid, 2 for burner #1 and 2 for burner #2. The output
voltage at these terminals is always the same as the controller supply voltage.
The pilot solenoid output connects to the pilot or low fire solenoid and is
energized when a start is initiated. Main solenoid, (main burner) energizes only
after the pilot or low fire flame has been proven. The time delay between proof of
flame and energizing of main output is factory set at 20 seconds. The solenoid
outputs are rated at 5A 250V each.
