Installation Instructions
General Information
Fenwal Series 05-14 Spark Ignition Systems are
manufactured and tested to the most rigid quality
control standards. Strict adherence to these
instructions will assure satisfactory performance.
WARNING: This ignition system complies with
the Z21.20 ANSI Standards for gas burner auto-
matic ignition systems when installed with Fenwal
specified electrodes and high voltage lead wires.
The replacement of components or any alterations
to this control board will invalidate our warranty,
void agency certifications and can create hazard-
ous conditions that may cause property damage,
personal injury or even death.
Operation
On a call for heat, input power is applied to
control board, sparking is then initiated and the
gas valve is energized. Sparking continues with
the gas valve powered for a specified "trial-for-
ignition" period. (See Specifications for timing
periods.)
In normal operation, as soon as flame is estab-
lished and proven by the flame sensing circuitry,
sparking will cease immediately and the system
will remain "on", monitoring the flame until the
end of the duty cycle.
Should a flame-out occur during the duty cycle,
the system will reactivate the spark with 0.8
seconds, to provide for re-ignition. The flame will
either be re-established within the "trial-for-
ignition" time, or the system will lock-out in the
normal manner. Should lock-out occur, reset
action (manual or thermostatic) must be taken
before the unit can be recycled. Reset action may
be accomplished at either the thermostat or at the
control unit circuit breaker, depending on the model
number of the unit. If the ignitor is a manual reset
model (05-140X0X-00X), the circuit breaker will
trip several seconds after sparking stops and the gas
valve is deenergized. If the ignitor is designed for
thermostatic reset, (05-1420X0X-00X), the circuit
breaker will only trip after several attempts at re-
ignition.
Thermostat Reset (Line Interruption)
Should the 05-14 series with the thermostat reset
(models designated 05-142X01-0XX) go into lock-
out due to loss of flame, the thermostat should be
momentarily turned below set point or the control
switch opened to initiate recycling. Lowering the
thermostat below ambient will normally recycle the
system. If several attempts at thermostatic reset do
not result in ignition, a manual reset button on the
ignitor module will actuate, preventing further
recycling.
Manual Reset
The manual reset feature, available on models
designated 05-140X01-00X requires manual
resetting of the system in the event of lock-out.
