Venting Multiple Appliances Into A Common Chimney Or Flue

The area around the flue piping should be sealed where it enters the chimney. When venting two appliances separately into a common chimney, always install the smaller flue pipe (appliance with lowest GPH input) at a higher point into the chimney than the larger flue pipe for the appliance with the largest GPH input. Refer to Figure 2.
