Double Wall Stove Pipe Clearance. To 6 in the closest clearance to a wall of any connector pipe. Clearance to non combustible materials is 0 but pipes should not actually touch cement bricks or other non combustibles. Dvl improves stove performance by maintaining high flue gas temperatures for a strong steady draft.
Dvl s double wall air insulated design reduces clearances to combustibles from 18 to 6 the closest clearance to a wall of any connector pipe. To 6 in the closest clearance to a wall of any connector pipe.
For example a single wall stove pipe requires 18 inches of clearance from ceilings or walls.
Double wall system features a black aluminized steel outer casing and stainless steel inner liner. When combining lengths remember to subtract 1 5 from each to account for overlap. Double wall stove pipe can reduce the clearance needed to combustibles in many situations and typically has a stainless steel inner wall that will provide a much loger time of service that a typical single wall setup. Using a heat shield on a single wall stovepipe allows you to reduce the clearances from 18 to 6 to the wall and 9 to the ceiling.
