larger in diameter than vent pipe.
• Boiler installed with single wall vent, must have 6”
clearance between its surface and any combustible
material. New Type B gas vent or
fl
exible liner must be
installed in accordance with instructions furnished with
vent. Maintain clearances as speci
fi
ed for vent pipe.
• Verify vent pipe is
fi
re-stopped where it goes through
fl
oor or ceiling. It should have approved vent cap with
clearances from roof. If clearances are less than shown,
have vent checked by local authorities. Figure 7, Page 11 .
• Vent connectors serving appliances vented by natural
draft shall not be connected into any portion of
mechanical draft systems operating under positive
