The vent connector should be sloped up toward the chimney 1/4" per foot. Ensure that the vent connector is properly supported and each connection securely fastened with at least 3 corrosion resistant sheet metal screws. The termination of the vent pipe must be flush with the inside of the chimney flue.
CAUTION: The vent connector length must never exceed 3/4 of the height of the chimney or venting problems will occur!
Always provide a minimum clearance of 6 inches between single wall metal vent pipe and any combustible materials. Type B1 vent may be used, clearance between it and any combustible material must be as listed.
WARNING: Failure to maintain minimum clearances between vent connectors and combustible materials can result in a fire causing extensive property damage, severe personal injury or death!
