Lighting the burner

Caution
Do not operate the water heater until the storage vessel
is completely filled with water, with water running from all
hot taps.
Open the main gas supply cock after all connections to the gas
control are completed and test all connections, using proprietary
leak detection fluid.
1. Remove outer cover and slide inner cover to right. (On 63/62
and 84/87 Models, raise the inspection port cover). Wait for 3
minutes for any unburnt gas to vent.
2. Turn the gas control knob to pilot.
3. Fully depress the gas control knob and the piezo igniter. With
the pilot burner alight, hold gas control knob in for 20
seconds. When gas control knob is released, the pilot
should remain lit. If not, repeat this operation.
4. Close and refit covers.
