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.
