What the Flame Rollout / Spill Switch Does

The flame rollout / spill switch is a safety cutout that trips if flame or flue gases escape the combustion chamber — a sign of a blocked heat exchanger or flue. A tripped rollout switch always means an underlying problem that must be diagnosed.

A heat-sensing switch positioned near the burner or draft hood opens the gas circuit if it detects flame rollout or flue spillage, shutting the boiler down to prevent a hazard.

We supply and fit the flame rollout / spill switch as part of a complete boiler repair or new installation, and inspect it during annual maintenance for homes across Greater Vancouver.
