5Vertical direct venting

Vertical termination – optional concentric vent: Models 399 - 600 Only

Description and usage

Lochinvar offers an optional concentric combustion air and vent pipe termination kit. Both combustion air and vent pipes must attach to the termination kit. The termination kit must terminate outside the structure and must be installed as shown in FIG. 5-4.

Field supplied pipe and fittings are required to complete the installation.

The required combustion vent pipe fittings are listed in Table 3A, on page 18 of this manual.

Vertical termination installation

1.See Section 5, Vertical Direct Venting - Determine Location (where applicable).

Figure 5-4Concentric Vertical Termination

2.Cut one (1) hole (7 inch (178 mm) diameter for #CVK3007 installations) into the structure to install the termination kit.

3.Partially assemble the concentric vent termination kit. Clean and cement following the cleaning procedures in these instructions.

a.Cement the Y concentric fitting to the larger diameter kit pipe (see FIG. 4-8, page 27).

b.Cement rain cap to the smaller diameter kit pipe (see FIG. 4-8, page 27).

NOTICE

Instead of cementing the smaller pipe to the

rain cap, a field supplied stainless steel screw

 

 

 

may be used to secure the two (2)

￿WARNING

When using the alternate screw assembly method, drill a clearance hole in the rain cap and a pilot hole in the vent pipe for the screw size being used. Failure to drill adequate holes may cause cracking of PVC components, allowing combustion products to be recirculated. Failure to follow this warning could result in personal injury or death.
