Do not use PVC pipe cement to connect the Polypro to PVC adapter. Use of PVC pipe cement will lead to
failure of the adapter, resulting in an exhaust gas leak which will cause property damage, severe personal
injury, or death.
Be certain to properly secure the Polypro to PVC adapter. Failure to do so will lead to an exhaust gas leak,
resulting in property damage, severe personal injury, or death.
Failure to properly pitch venting system could cause condensate to collect and pool, resulting in venting system
failure, property damage, severe personal injury, or death.
