12.11.3 - Multiventing

sidewall terminations

When two or more direct vent

appliances are vented near each

other, each appliance must be

individually vented and vent

terminations may be installed as

shown in Figure 12-21. It is important

that vent terminations be made as

shown to avoid recirculation of flue

gas.

WARNING!!!

Do not

connect any other appliance

to the vent pipe or multiple

heaters to a common vent

pipe. Failure to comply could

result in severe personal injury,

death, or substantial property

damage.

NOTICE!

Keep the terminals horizontally in the same

line and at min. 12” from grade or snow line.
