12. All piping must be fully supported. Use pipe hangers at a minimum of 4 foot intervals to prevent sagging of the pipe where
condensate may form.
13. Do not use the appliance to support any piping.
14. A screened straight coupling is provided with the appliance for use as an outside exhaust termination.
15. A screened inlet air tee is provided with the appliance to be used as an outside intake termination.

1. DIRECT VENT INSTALLATION OF EXHAUST VENT AND INTAKE PIPE
If installing a direct vent option, combustion air must be drawn from the outdoors directly into the appliance intake, and exhaust must
terminate outside. There are three basic direct vent options detailed in this manual: 1. Side Wall Venting, 2. Roof Venting, and 3.
Unbalanced Venting.
Be sure to locate the appliance such that the exhaust vent and intake piping can be routed through the building and properly
terminated. Different vent terminals can be used to simplify and eliminate multiple penetrations in the building structure (see Optional
Equipment in Venting Section). The exhaust vent and intake piping lengths, routing and termination methods must all comply with the
methods and limits given in the Venting section, Part 5 of this manual.
When installing a combustion air intake from outdoors, care must be taken to utilize uncontaminated combustion air. NOTE: To
prevent combustion air contamination, see Table 1.
Take extra precaution to adequately support the weight of vent pipes terminating through the roof. Failure to properly support roof
terminated vent piping could result in property damage, serious personal injury, or death due to flue gas leakage.
