5 Vent Information and Diagrams

A. Vent Table Key

The abbreviations listed in this vent table key are used in the vent diagrams.

Symbol	Description
V1	First section (closest to appliance) of vertical length
V2	Second section of vertical length
H1	First section (closest to appliance) of horizontal length
H2	Second section of horizontal length

WARNING

Fire Hazard. Explosion Risk. Asphyxiation Risk.

Do NOT connect this gas appliance to a chimney flue serving a separate solid-fuel or gas burning appliance.

• Vent this appliance directly outside.

• Use separate vent system for this appliance.

May impair safe operation of this appliance or other appliances connected to the flue.

B.Use of Elbows

CAUTION

ALL vent configuration specifications MUST be followed.

•This product is tested and listed to these specifications.

•Appliance performance will suffer if specifications are not followed.

C. Measuring Standards

Vertical and horizontal measurements listed in the vent diagrams were made using the following standards.

1.Pipe measurements are shown using the effective length of pipe (see Figure 5.2).

2.Measurements are made from the appliance outer wrap, not from the standoffs.

3.Horizontal terminations are measured to the outside mounting surface (flange of termination cap) (see Fig- ure 4.1).

4.Vertical terminations are measured to bottom of termi- nation cap.

5.Horizontal pipe installed level with no rise.

Diagonal runs have both vertical and horizontal vent as- pects when calculating the effects. Use the rise for the ver- tical aspect and the run for the horizontal aspect (see Fig- ure 5.1).

Two 450 elbows may be used in place of one 900 elbow. On 450 runs, one foot of diagonal is equal to 8.5 inches hori- zontal run and 8.5 inches vertical run. A length of straight pipe is allowed between two 450 elbows (see Figure 5.1).
