Maximum Three 3 90 Elbows Per Installation

WDV Series Gas Fireplace	venting installation

VERTICAL/Horizontal termination configurations

Since it is very important that the venting system main- tain its balance between the combustion air intake and the flue gas exhaust, certain limitations as to vent con- figurations 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. Figure 10

NOTE: Horizontal and vertical sections of this vent system require a minimum of 1" clearance to combustibles at the top, sides and bottom.

When vent exits through foundations less than 20" below outcrop, the termination 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 finished outside wall.

•The maximum number of 90° elbows per side wall installation is three (3). Figure 11

•A minimum of 12" is required before a 90° elbow. If a 90° elbow is fitted directly after 12" vertical section mounted to the top of the fireplace, the maximum horizontal vent run before the termination or a vertical rise is 36” (914 mm). Figure 12

•If a 90° elbow is used in the horizontal vent run (level height maintained) the horizontal vent length is reduced by 36". Refer to Page 17, Figures 11 and 12. This does not apply if the 90° elbows are used to increase or redi- rect a vertical rise. Figure 14

Example: According to the vent graph (Page 13) the maxi- mum horizontal vent length in a system with a 10' vertical rise is 17Z\x’ (5.3 m) and if a 90° elbow is required in the horizontal vent it must be reduced to 14Z\x' (4.4 m).

In Figures 13 and 14 dimension A plus B must not be greater than 17' (5.2 m).

•The maximum number of 45° elbows permitted per side wall installation is two (2). These elbows can be installed in either the vertical or horizontal run.

•For each 45° elbow installed in the horizontal run, the length of the horizontal run MUST be reduced by 18" (45 cm). This does not apply if the 45° elbows are installed on the vertical part of the vent system.

•The maximum number of elbow degrees in a system is 270°. Figure 15
