First of all, ensure your gas supply is turned on. When you’re sure that it is, look for your control panel which is behind a door or behind fireplace grates. Locate igniter and on/off knobs which are beside each other. The first one is usually red or black. Then turn the on/off knob to the “pilot” setting and push it to allow a little gas to flow. While doing this, you’ll need to push the igniter button at the same time. You need to press it every thirty seconds, three times, to ignite the pilot light. Hold the button for another ten to fifteen seconds. It should then stay lit and you can turn the knob to the “on” position.
If you’re experiencing a power cut, follow the same steps.
