• 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

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.
Diagonal runs have both vertical and horizontal vent as- pects when calculating the effects. Use the rise for the vertical aspect and the run for the horizontal aspect (see Figure 5.1).
Two 45º elbows may be used in place of one 90º elbow. On 45º runs, one foot of diagonal is equal to
Verticalin.

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.Horizontal terminations are measured to the outside mounting surface (flange of termination cap) (see Figure 4.1).
3.Vertical terminations are measured to bottom of termi- nation cap.
4.Horizontal pipe installed level with no rise.
