Installation & Operation Manual

4 Sidewall direct venting (continued)

Sidewall termination – optional concentric vent

Description and usage

Lochinvar offers optional concentric combustion air and vent pipe termination kits (Factory Kit #CVK3003 for 3" diameter

-Models 81 - 211 and #CVK3007 for 4" diameter - Model 286). Both combustion air and vent pipes must attach to the termination kit. The termination kits must terminate outside the structure and must be installed as shown below

in

FIG. 4-6.

The required combustion air and vent pipe materials are listed in Table 3A, on page 17 of this manual.

Figure 4-6Concentric Sidewall Termination

e.Do not terminate above any door or window. Condensate can freeze, causing ice formations.

f.Locate or guard vent to prevent condensate damage to exterior finishes.

4.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.

5.Partially assemble the concentric vent termination kit. Clean and cement using the procedures found in these instructions.

a.Cement the Y concentric fitting to the larger kit pipe (FIG.’s 4-7 and 4-8).

b.Cement the rain cap to the smaller diameter kit pipe (FIG.’s 4-7 and 4-8).

1.Determine the best location for the termination kit (see FIG. 4-6).

2.The total length of piping for vent or air must not exceed the limits given in the General Venting section on page 19 of this manual.

3.You must consider the surroundings when terminating the vent and air:

a.Position the vent termination where vapors will not damage nearby shrubs, plants or air conditioning equipment or be objectionable.

b.The flue products will form a noticeable plume as they condense in cold air. Avoid areas where the plume could obstruct window views.

c.Prevailing winds could cause freezing of condensate and water/ice buildup where flue products impinge on building surfaces or plants.

d.Avoid possibility of accidental contact of flue products with people or pets.
