Install the wiring base where the relative humidity never reaches the saturation point. The Burner-
PRO is designed to operate in a maximum 90% relative humidity environment. Do not install the
BurnerPRO where it can be subjected to vibration in excess of 0.5G continuous maximum vibration.
Allow at least one inch clearance (2.5 cm) around control for service and installation.
1.
Wiring must comply with all applicable codes, ordinances and regulations.
2.
Wiring must comply with NEC Class 1 (Line Voltage) wiring or equivalent regional code.
3.
Torque rating on terminal block screws is 4.4 in/lbs to 5.3 in/lbs.
4.
Limits and interlocks must be rated to simultaneously carry and break current to the ignition
transformer, pilot valve and main fuel valve(s).
5.
Recommended wire routing of lead wires:
6.
Maximum wire lengths:
A good grounding system should be provided to minimize the effects of AC quality problems. A
properly designed ground system meeting all the safety requirements will ensure that any AC voltage
quality problems, such as spikes, surges and impulses have a low impedance path to ground. A low
impedance path to ground is required to ensure that large currents involved with any surge voltages
will follow the desired path in preferences to alternative paths, where extensive damage may occur to
equipment.
WARNING: Controls require safety limits utilizing isolated mechanical contacts. Electronic
limit switches may cause erratic operation and should be avoided.
BEFORE INSTALLING THE BURNERPRO CONTROL
CAUTION: Ensure that electric power is turned off. Refer to SN-100 for recommended
grounding techniques. Ensure that wiring base terminal is connected to protective earth.
Be aware that power to some interlocks (operating controls, air flow switches, modulating
circuits, etc.) may be derived from sources other than what is controlling the BurnerPRO.

a. Do not run high voltage ignition transformer wires in the same conduit with any other
wires.
b. Do not route flame detector lead wires in conduit with line voltage circuits. Use separate
conduit where necessary.
a.The maximum lead wire length is 200ft. (61 meters) to terminal inputs (Operating limits,
interlocks, valves, etc.).
b. Flame Detector lead wires: see section on flame scanners
c. Remote reset: The maximum length of wire is 500 feet (152 meters) to a normally open
remote reset push-button, but should remain within sight and sound of the burner.
