MEASURES AND CHECKS BEFORE START-UP, 1-STAGE BURNER
GENERAL RULES
Care should be taken by the installer to
ensure that no electrical cables or fuel/
gas pipes are trapped or damaged
during installation or service/
maintenance.
INNER ASSEMBLY
Ensure that the ignition and ionisation
electrodes are correctly adjusted. The
sketch shows the correct measure-
ments.
GAS QUALITY
Ensure that the burner head is meant
for the gas quality to be used (see fig.).
VENTING
The gas line is vented by loosening the
screw on the test nipple for the inlet
pressure. Connect a plastic hose and
conduct the gas into the open. After
having vented the gas line tighten the
screw again.
LEAKAGE CONTROL
When making a leakage control of the
gas supply system the solenoid valve
should be closed. Connect a pressure
gauge to the test nipple Pa, see fig.
The test pressure in the system should
be 1,5x max. inlet pressure or min.
150 mbar. If any leakage, locate the
source by means of soapy water or a
leak location spray. After tightening
repeat the test.
ELECTRIC FUNCTION TEST:
Ensure that phase and neutral are not
reversed. The gas shut-off cock should
be closed.To prevent the gas pressure
switch from locking out it should be
linked temporarily.
After the main switch has been swit-
ched on and the thermostats have
been adjusted the pre-purging period
begins (30-35sec.). At the end of this
period the pre-ignition period starts
(0,5-2,5 sec. dependent on the design
of the gas control). The gas valve is
energized and opens and flame is
established. At the end of the safety
time (2-3 sec.) the gas control locks
out. The solenoid valve and the motor
will be "dead". Remove the link from
the gas pressure switch after the test
is finished.

LEAKAGE CONTROL
NOTE! APPLIES ONLY TO GAS
BURNER CONTROL LFL1.
When using LPG (Propane) the burner
should be connected for post-purge.
Move connection to terminal 6 to ter-
minal 7 in the base of LFL1.
