Installation & Operation Manual

5 Vertical direct venting (continued)

Vertical termination – optional concentric vent: Models 151 - 601

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 and fittings are listed in Table 3A, on page 19 of this manual.

Vertical termination installation

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

2.Cut one (1) hole (5 inch diameter for #CVK3003 installations or 7 inch 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.’s 4-8 and 4-9, page 28).

b.Cement rain cap to the smaller diameter kit pipe (see FIG.’s 4-8 and 4-9, page 28).

c.Do not attach a U-Bend to the rain cap. Doing so could cause recirculation (see FIG. 5-5).

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)

 

components together when field disassembly

 

is desired for cleaning (see FIG. 4-12, page

 

29).

￿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.
