Horizontal Termination Configurations

VENT INSTALLATION

Since it is very important that the venting system maintain its balance between the combustion air intake and the flue gas exhaust, certain limita- tions as to vent configurations apply and must be strictly adhered to.

The Vent Graph, showing the relationship between vertical and horizontal side wall venting, will help to determine the various dimensions allowable.

See Figure 20.

NOTE: Horizontal sections of this vent system require a minimum of 3" clearances to combustibles at the top of the ﬂue and 1" clearance at the sides and bottom until the ﬂue penetrates the outside wall. A minimum 1" clearance all around the ﬂue is acceptable at this point of penetration.

Vertical sections of this vent system require a minimum of 1" clearance to combustibles on all sides of the pipe.

When vent exits through foundations less than 20" below outcrop, the termi- nation must be flush up with outcropped wall above.

It is best to locate the fireplace in such a way that minimizes the number of offsets and horizontal vent length.

The horizontal vent run refers to the total length of vent pipe from the flue collar of the fireplace (or the top of the Transition Elbow) to the face of the outer wall.

WARNING

When installing the appliance as a rear vent unit, the 90° or 45° transition elbow attached directly to the rear of the unit is NOT INCLUDED in the following criteria and calculations, and unless speciﬁcally mentioned should be ignored when calculating venting layouts.

•The maximum number of 90° elbows per side wall installation is three (3). See Figure 21.

•If a 90° elbow is fitted directly on top of the fireplace flange the maximum horizontal vent run before the termination or a vertical rise is 36” (914 mm). See Figure 22.
