2Installing Vent Pipe

Note: For termination cap installations only, go directly to Sec- tion E.

Note: Heat shields MUST overlap by 1-1/2 in. min. for rear vented appliances.

A. Clearances for the Vent Sections

•Top Vented Direct Vent Appliances

For all top vented, direct vent appliances, clearances to combustible materials from the venting system need to be maintained as shown in Figure 2.1.

•Rear Vented Direct Vent Appliances

See Figure 2.2.

Note: Refer to the appliance installation instructions for al- lowed vent lengths and configurations.

B. Penetrating a Wall

Wherever a combustible wall is penetrated, the hole must be framed with an interior wall shield (DVP-WS) as shown in Figures 2.3-2.4. This shield maintains minimum clearances and restricts cold air infi ltration. If the wall being penetrated is of noncombustible materials (material which will not ignite or burn, or has a UL fi re rating of zero), a 9 in. diameter hole is acceptable. Whenever a wall is penetrated the wall shield is only required on one side and no heat shield is necessary. If your local inspector requires the wall shield on both sides, then both wall shields must have a heat shield attached to them.
