HBDV7 Series Direct Vent Gas Fireplace

VENTING INSTALLATION

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 cri- teria and calculations, and unless specifically men- tioned should be ignored when calculating venting layouts.

• The maximum number of 90° elbows per side wall in-

stallation is three (3). Figure 23

The maximum number of elbow degrees in a system is 270°. Figure 27

Example:

Elbow 1

= 90°

 

 

Elbow 2

= 45°

 

 

Elbow 3

= 45°

 

 

Elbow 4

= 90°

Total angular variation

= 270°

• If a 90° elbow is fitted directly on top of the fireplace

flange the maximum horizontal vent run before the ter-

mination or a vertical rise is 36” (914 mm). Figure 24

• If a 90° elbow is used in the horizontal vent run (level

height maintained) the horizontal vent length is re-

duced by 36” (914 mm). Figures 24 & 25. This does

not apply if the 90° elbows are used to increase or

redirect a vertical rise. Figure 23

Maximum horizontal run with no rise

Example: According to the vent graph (Page 14) the maximum horizontal vent length in a system with a 7Z\x’ (2.3 m) rise is 20’ (6 m) and if a 90° elbow is required in the horizontal vent it must be reduced to 17’ (5.2 m).

In Figures 26 & 27, dimension A plus B must not be great- er than 17’ (5.2 m)

The maximum number of 45° elbows permitted per in- stallation is six (6). 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” (457 mm). This does not apply if the 45° elbows are installed on the vertical part of the vent system.
