  • Sheet metel screws for single wall vent pipe, any code requirment?

    As a rule I try to do things to code and wondering what size sheet metal screws to use? Is there a code requirement or just use what will work? How fare in to chimney should a single wall water heater vent pipe protrude in to chimney?

    3/4" self drilling/tapping with 1/4" hex head screws seem to be the norm. Longer is just a waste. A minimum of 3, evenly spaced around is required. The pipe should extend the length of the crimped section into the liner of the chimney OR far enough to provide a good seal against leakage and for drafting. A good high temperature silicone or furnace cement should be used at the junction of the 2 materials.
