Product Information

The 3-2-10 chimney rule refers to the clearance distances required between a chimney and nearby structures. It typically means that the chimney should be at least 3 feet from any wall or roofline within 10 feet horizontally. Leaving the damper open overnight is generally safe if there is a fire burning. However, it can lead to heat loss and is not necessary once the fire has extinguished.

The smallest flue pipe size used for residential appliances is typically 2 inches in diameter. However, larger sizes are more common for water heaters and heating appliances. The code size for vent pipes depends on local building codes and the appliance’s BTU rating. Common sizes are 3 inches and 4 inches in diameter for residential appliances. The maximum distance for direct venting a water heater depends on the manufacturer’s guidelines and local building codes. Typically, it can be up to 40 feet horizontally and 100 feet vertically. The distance from the flue to the wall should follow local building codes and the manufacturer’s recommendations for clearance distances.Our Flexible flue liner is available in both 316 grade stainless steel and 904 grade (Lifetime warranty). Both are suitable to reline your chimney for use with a multi fuel stoves and wood burners and are HETAS approved, for further information please refer to the flexible flue liner section. Flue pipes should have a slight upward slope from the appliance to the vent termination to prevent condensate buildup and aid in proper draft.

A flue that is too short may not provide adequate draft to vent combustion gases properly, leading to poor appliance performance and potential safety hazards.For a water heater, the size of the chimney liner depends on the BTU rating of the water heater and the height of the chimney. It is essential to follow the manufacturer’s guidelines or consult a professional to determine the appropriate size.
