Pilot gas connection at outlet side (if applicable)
•
Square off the end of tubing and remove burrs.
•
Slip compression fitting over 4 mm tubing.
•
Insert tubing into automatic gas control housing until it
bottoms, slide fitting into place and turn finger tight.
•
Use a wrench to tighten fitting about 1
finger tight to shear of the olive.Do not use jointing
compound.
Connect other end of tubing to pilot burner according to the
manufacturer's instructions.
CAUTION
Do not bend tubing at gas control after compression
fitting has been tightened, as this may result in gas
leakage at the connection.
Perform gas leak test
WARNING
FIRE OR EXPLOSION HAZARD CAN CAUSE
PROPERTY DAMAGE, SEVERE INJURY OR
DEATH
Check for gas leaks with a rich soap and water
solution any time work is done on a gas control.
Gas leak test
•
Paint all pipe connections upstream of the gas control
with with a rich soap and water solution.Bubbles indicate
a gas leak.
•
If a gas leak is detected, tighten the pipe connection.
•
Stand clear while lighting the main burner to prevent
injury caused from hidden gas leaks, which could cause
flasback in the appliance vestibule. Light the main burner.
•
With the main burner in operation, paint all pipe joints
(including adapters) and gas control inlet and outlet with
with a rich soap and water solutionan approved leak
detection fluid.
•
If another gas leak is detected, tighten adapter screws,
joints and pipe connections.
•
Replace the part if gas leak can not be stopped.

Fusing
In order to prevent unsafe conditions at too high current, the
ignition control has an integral non replaceable fuse.
This fuse will be blown long before the maximum 16 A
external fuse switches off.
Spark gap
Max. allowable spark gap 3.5 mm

CAUTION
Keep soap and water solution away from electrical
connections.
Disconnect power supply to prevent electrical shock
and/or equipment damage.
Wiring must be in accordance with local regulations.
The appliance manufacturer's instructions should
always be followed.
Before installing or replacing any control check that
type number is correct for the application.
Ensure combustion chamber is free of gas before
start up.
Conduct a thorough check out when installation is
completed.
At the first start the ignition control can be in lock-
out; depress reset button to free the ignition control.
Use leadwire which can withstand 105 °C ambient.
Use leadwire which is proven against moisture.
Wiring between ignition control and spark sensing probe
should have good quality insulation, suitable for the
temperatures encountered.
WARNING
If ignition control seems to operate normally but does
not detect flame, check for right polarity of power
supply (line, neutral).
The minimum value should be in accordance with the
specified value of the ignition control.
To check flame current connect a DC micro-Ampèremeter
between flame sensing wire and flame sensing rod.
If flame current is insufficient check that flame sensing
rod is fully enveloped by the flame and that burner is
reliable grounded to ignition control.
If there is no sufficient flame current due to phase-phase
mains it is recommandable to use a AT7030A or AT7030B
flame detection transformer. See also EN1R-9136
instruction sheet AT7030.
WARNING
Short µA meter during ignition to prevent damage of
the µA meter in single rod application.
