Tjernlund Spill Switch Kit

This Safety Interlock System may be used on conventional chimney or Power Vented appliances equipped with a draft hood, draft diverter or draft control. It's purpose is to provide a means for appliance shut-down in the event of flue blockage or down drafts. The Spill Switch circuits are “normally closed” and will not affect normal appliance operation. When concentrated spillage of combustion gases occurs from the draft hood, diverter or barometric control, the Spill Switch circuit will open preventing burner operation. ***WARNING*** The 24SP200 Flue Gas Spillage Sensing Kit is designed to alert the user to a potentially hazardous condition. It is not designed to, and cannot replace regular chimney inspection, appliance servicing and combustion testing. DO NOT USE THE 24SP200 AS A SUBSTITUTE FOR PROFESSIONAL APPLIANCE MAINTENANCE.
