Burner And Supply Pipe Installation; Preliminary Burner Checks - Valor Homeflame Dream Installation And Owner's Manual

10. BURNER AND SUPPLY PIPE INSTALLATION

10.1 Burner and supply pipe installation.
1. Remove the 'Aeration checking' reminder label from the top of the burner.
2. Refit the burner unit to the convection box with the two screws removed previously.
3. Connect the supply line to the appliance.
4. If closed open the isolating valve at the inlet 'T' connector.
,
5. Turn on the gas supply and pressure check the installation pipework for gas
soundness. In the United Kingdom (GB) check in accordance with the current edition
of BS 6891. In the Republic of Ireland check in accordance with the current edition of
IS 813 "Domestic Gas Installations".

10.2 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 'T' connector.
,
2. Rotate the control pivot bracket clockwise as far as it will go and hold in this position
(See figure 25). 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.
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.
5. Align the hole near the bottom of the control linking bar with that in the control pivot
bracket. Join them with the knurled shouldered screw removed previously.
