Installation & Operation Manual

4 Sidewall direct venting (continued)

Sidewall termination – optional concentric vent: Models 400 - 601 Only

Description and usage

Lochinvar offers an optional concentric combustion air and vent pipe termination kit (#CVK3007 for 4" (102 mm) diameter - Models 400 - 601). 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 below in FIG. 4-7.

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

The required combustion vent pipe materials are listed in Table 3A, on page 18 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.

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

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