PTRAP TO FACE AWAY FROM ROOF. EXHAUST TERMINATION CAP MODEL PVVTC, PTRAP OR 2 90° ELBOWS OPTION 3” - 24” Colinear Direct Vent - Insert Installation Figure 29 Colinear Direct Vent - Pitched Roof Installation Figure 30 Determining Minimum Vent Height Above the Roof WARNING: Major U.S. building codes specify minimum chimney and/or vent height above the rooftop. These minimum heights are necessary in the interest of safety. These specifications are summarized in Figure 30. ROOF PITCH H (Min.) Flat to 6/12 12” (305mm) 6/12 to 7/12 15” (381mm) Over 7/12 to 8/12 18” (457mm) Over 8/12 to 16/12 24” (610mm) Over 16/12 to 21/12 36” (914mm) Figure 31 In both vertical and horizontal colinear direct vent applications, a colinear transition plate model PVCT can be used to minimize clearances between intake and exhaust pipes. For exhaust and intake air, cap pipes with any of the following: Vertical termination cap (model #PVVTC), PTrap, or two 90. elbows. When transition plate (model PVCT) is used, two termination caps (model PVVTC) may NOT be used. Note: If transition plate (model PVCT) is used, the measurement for center to center of the pipes will be 2.5”. If the transition plate (model PVCT) is not used, the measurement for center to center of the pipes can be 3” to 24” maximum. Note: Exhaust must be a minimum of 3” above air intake inlet. 22618-12-0707 Page 27 PVCA HORIZONTAL COLINEAR DIRECT VENT ADAPTOR COLINEAR ADAPTER 1. Attach colinear adaptor to back of heater with two (2) screws. 2. When adapter is connected, continue with your vent run. Cementing PVC joint is recommended, but not required on colinear fresh air intake adaptor. Colinear adaptor Colinear adaptor to be used in conjunction with single flue horizontal vent kit PVVK-SH. The two attachments are used for colinear direct vent installation. 4 13/16” 3 15/16” 6 1/8” 7 9/16” PVVTC TERMINATION CAP VENT KIT Available from Empire Comfort Systems, Inc.

Use outdoor sealant to seal transition plate to the roof or chimney chase. 2. Check local codes to determine air intake height from roof. The minimum height for this application is 12”. 3. Cut 1 1/2” PVC pipe to correct height. Attach pipe, PTrap, and exhaust cap to plate. Glue all joints with PVC cement. Note: Must maintain a minimum 3” between exhaust outlet and air intake. Horizontal Application 1. Attach plate to outside wall with four (4) screws. Use outdoor sealant to seal transition plate to the wall. 2. Cut 1 1/2” PVC pipe to correct length. The minimum length for this application is 9” for the exhaust and 6” for the air intake.
