•The control panel can be mounted on the unit skid or on a
building wall providing it does not infringe on a Class 1,
Division 1 area.
•Use control panel mounting tabs to mount in a location that
faces away from the burner housing so the operator is facing
both the enclosure and the burner housing while operating.
Other considerations may include panel access, trafc,
wire-runs and visibility.
•The control panel should be mounted about 1.5m (5’) above
ground level.
•If an external ignition coil is used, it must be mounted in a
Class 1, Division 2 enclosure or a non-hazardous location,
ideally inside the burner housing.
1.1 Mounting Locations
Any design used, should be approved by a qualied inspector
and approved by the gas authority having jurisdiction at the site
where the system is to be installed.
Additional P&ID and wiring diagrams are provided in a separate
application note.

4-20mA Out + 4-20mA output intended to drive a
proportional control valve. This out-
put will be connected to a Current
to Pressure converter which will
drive a proportional control valve.
A software control loop is impli-
mented to tune the ame to match
the demand. Proportional control is
optional.
A resistance of 120Ω to 250Ω is expected.
4-20mA Out - Ground Ground return for the 4-20mA output

the “+” and “-” terminals and must not be electrically

High Fire/Main + Positive terminal
of the High Fire / Main valve
Solenoid valves must be connected between the “+” and “-”
terminals. The negative terminal is not directly connected to ground
so a common return wire for the High Fire, Low Fire and Pilot
valves cannot be used.
Maximum continu-
ous current is 2A. If
“Low Power” mode is
enabled, a peak load of
4A is permitted.
High Fire/Main - Negative terminal
of the High Fire / Main valve
Low Fire + Positive terminal
of the Low Fire valve
Solenoid valves must be connected between the “+” and “-”
terminals. The negative terminal is not directly connected to ground
so a common return wire for the High Fire, Low Fire and Pilot
valves cannot be used.
Low Fire - Negative terminal
of the Low Fire valve
Pilot + Positive terminal
of the Pilot valve
Solenoid valves must be connected between the “+” and “-”
terminals. The negative terminal is not directly connected to ground
so a common return wire for the High Fire, Low Fire and Pilot
valves cannot be used.
Pilot - Negative terminal
of the Pilot valve
Ion + Flame Detection Input.
Connected to a Flame-rod.
A Kanthal rod should be placed directly in the pilot ame and
connected to this input. The pilot assembly must be grounded for
the ame detection to function properly. Input is protected from
high voltage and can be connected in series with the high voltage
terminals of an external ignition coil, allowing a single ame-rod to
be used for both ignition and ame detection.
A 65VAC signal is ap-
plied to the ame rod.
The source impedance
is very high so there is
no danger of sparking.
Ion - Ground Ground return for ame detection. Must be connected to the
burner housing.

Coil + Driver for the low voltage primary of
the ignition coil.
The primary of the ignition coil should be connected to this termi-
nal. The 12/24VDC input power will be applied for 1 ms and turned
off for 50 ms while sparking.
This output is pro-
tected by a 250mA
thermal fuse.
