Installation MINIMUM AND MAXIMUM VENT LENGTHS Feet Meters Important information for all installations: 1) The minimum required venting is what is required to safely extend the inlet and outlet vent pipes outside of the building. 15.2 2) Each 90° elbow (standard or long sweep elbow) reduces the 18.3 equivalent vent length by 5 feet (1.5m). - Page 12 DO NOT use 6 inch rigid venting with concentric vent terminations. Note: For Horizontal Power Direct Vent configurations, GHE119SS/SU models will need to have a 45 degree elbow on the intake and a 90 degree elbow on the exhaust, if they are on the same plane.
- Page 13 Installation vent terminal is at least 2 feet (0.61 m) away from any- thing that can be damaged by the condensate HORIZONTAL VENT INSTALLATION – Once the vent terminal location has been determined, make a hole through the Min. 24" exterior wall to accommodate the vent pipe.

- Page 29 Installation The PVC to PP adapter should then be installed into the PVC couplings on the inlet air and exhaust vent installed on the unit. The sealing gasket will require some type of lubricant to make it easier to install the adapter. Both Centrotherm and M&G Duravent recommend a connector ring to be installed between the PVC part and the PP part.
