Burner Installation - Valor 4190 Installer's Manual

8.1 Refit the burner unit to the convection box with three screws.
8.2 Connect the supply line to the appliance.
8.3 Pressure check the installation pipework for gas soundness. In the United
kingdom check in accordance with the current edition of BS6891. In the Republic of
Ireland check in accordance with the rules in force.
8.4 Preliminary burner checks
Some burner operations can be checked at this stage. Checking now will mean that less
disassembly will be required if any problems are found. A full check should still be made,
however, after final installation.

8.4.1 If closed open the isolating valve at the inlet elbow.
8.4.2 Rotate the control pivot unit clockwise as far as it will go and hold in this
position (see section 3.1.2 and figure 6 ). This should close the ignition circuit and (now
that the gas is connected) simultaneously open the gas tap allowing the gas to flow to
the pilot.
Wait a few seconds while the air is purged. The electronically generated sparks should
light the pilot. The pilot should then light the main burner at its low setting. There may
be a delay of up to four seconds between the pilot lighting and ignition of the gas at the
main burner. This is normal and is due to the time required to fill the main burner
compartment with sufficient gas for ignition.
8.4.3 When the burner is operating properly, gradually turn the control pivot unit anti-
clockwise. The burner flames should gradually increase until the pivot unit is nearly at
its furthest anti-clockwise rotation. Rotating further until the pivot unit comes to a stop
should then turn the burner and pilot off. When the above checks have been completed
close the isolating valve on the inlet elbow.
8.4.4 If the above checks are satisfactory, continue with the installation. If not, check
the control and ignition circuitry and components as described in the servicing section
of this manual.
