Advanced Distributor Products 76740200 Flame Rollout Switch

The Advanced Distributor Products 76740200 Flame Rollout Switch is a safety part that is used to prevent dangerous accumulation of gases and subsequent explosions in residential and light commercial heating systems. Just like the pressure switch it, measures pressure within the chimney or vent system. If there is a buildup of pressure because of a blocked flue or incorrect venting, the switch will turn off the gas supply to the heating appliance, including furnaces, boilers or fireplaces. Flame Rollout Switch helps to minimize the chances of getting poisoned by carbon monoxide, getting burnt, or losing property by simply switching off the system immediately.
