Burner & Supply Pipe Installation
1.
Refit the burner unit to the hotbox with two screws.
2.
Connect the supply line to the appliance.
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.
9.2
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.
1.
If closed
,
open the isolating valve at the inlet elbow.
2.
Rotate the control pivot bracket clockwise as far as it will go and hold in this position
(See figure 23). This should close the ignition circuit and 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.
3.
When the burner is operating
properly, gradually turn the control pivot
bracket anti-clockwise. The burner
flames should gradually increase until
the pivot bracket is nearly at its furthest
anti-clockwise rotation. Rotating further
until the pivot bracket 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
.
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 guide.
