The ESP NT02 N-Take 2 is a patented flapper valve providing alternative combustion intake. It automatically opens in response to a slight vacuum inside the pipe, preventing furnace shutdown when the outdoor intake is blocked by snow or ice. Designed for installation within the draft induction supply line, between the outdoor intake and the furnace, it can be placed in various indoor locations. This device serves as an alternative, not primary, combustion inlet, suitable for 2" and 3" PVC systems.
Prevents furnace shutdown from blocked intake due to snow or ice.
