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).

Description and usage
Lochinvar offers optional concentric combustion air and vent
pipe termination kits (Factory Kit #CVK3003 for 3" diameter -
Models 150 - 199 and #CVK3007 for 4" diameter - Models 285 -
500). 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 vent pipe materials are listed in Table
3A, on page 15 of this manual.

Sidewall termination installation
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 17
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.
