Web5 Ensure the hot surface ignitor is positioned to provide consistent ignition. 6 Check for any cracks in ignitor assembly ceramic insulators - replace ignitor assembly if damaged. 7 Check resistance of ignitor at room temperature (77°F) at the plug end. Replace ignitor if resistance is not within 11.5 and 18.8 ohms at room temperature. WebOn the other hand, a hot surface igniter system that lights a pilot light first and allows the pilot to light the main burner will allow less gas into the atmosphere when the pilot valve inside the gas valve opens. In contrast, a direct main burner ignition system is going to open the valve and allow more gas into the atmosphere. alice garnier ardian
