INSTALL FOAM GASKET FLUE ADAPTOR PLASTIC GASKET THREADED CONNECTOR Attach flue adaptor to back of heater with four (4) screws. Note: No PVC cement is needed to install flue adaptor kit. Install plastic gasket and screw threaded connector to the flue adaptor. When these connections are made, continue with your vent run. Cement all PVC joints on vent run.

Equivalent With Three (3) 90° Elbows Special Note: The vent terminal 90° elbow and first 90° elbow off back of the heater, when within 6” (15.2 cm), do not contribute to the overall vent length measurement. For each 45° elbow installed in the horizontal run, the length of the horizontal run MUST be reduced by 1.5 feet (45 cm). This does not apply if the 45° elbows are installed on the vertical part of the vent system. Reduce the length of the horizontal run 3 feet (91.4 cm) for every 90° elbow. Note: On horizontal runs, a P.V.C. support clamp needs to be installed every 3 feet. No “sags” in horizontal vent runs; water will settle in the pipe. When installing a colinear horizontal, the minimum vent length protruding from the outside wall is 6” (15.2 cm) for air intake and 9” for exhaust. See Figure 27. Note: Horizontal discharge 90° elbow must be pointed downward. See Figure 26. All horizontal runs require either a 1/4” per foot rise to run condensation back to the heater, or a 1/4” per foot downward slope to run condensation away from the heater. Note: All PVC vent run piping can be purchased at a local hardware store. Schedule 40 PVC pipe should be used and cemented. PVCA Horizontal Colinear Direct Vent Adaptor, PVVTC Cap, PVVK-CFA Flex Kit and PVVK-SH Horizontal Vent Adaptor Kit are available from Empire Comfort Systems, Inc. Figure 24 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 horizontal colinear direct venting, exhaust and intake air, cap pipes with 90. elbows, pointed downward. 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: Must maintain a minimum 3” between exhaust outlet and air intake.

These minimum heights are necessary in the interest of safety. Special Note: The vent terminal (PTrap, Vent cap or two 90° elbows) and first 90° elbow off back of the heater, when within 6” (15.2 cm) off back of the heater, do not contribute to the overall vent length measurement. For each 45° elbow installed in the horizontal run, the length of the horizontal run MUST be reduced by 1.5 feet (45 cm). This does not apply if the 45° elbows are installed on the vertical part of the vent system. Reduce the length of the horizontal run 3 feet (91.4 cm) for every 90° elbow. Note: Exhaust must be a minimum of 3” above air intake inlet.

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. No...
