D2241 (SDR-21 and SDR-26 PVC), D2261 (ABS-DWV), or F628 (Schedule 40 ABS. Pipe cement and primer must conform to ASTM Standards D2564 (PVC) or D2235 (ABS). 1. Mark vertical combustion air inlet centerline on ceiling. Cut hole for combustion air inlet piping. Clearance to combustible materials is not required. 2. Cut hole in roof. Provide minimum 12” (30.5 cm) vertical separation between combustion air inlet pipe and roof jack vent cap. Clearance to combustible materials is not required. 3. Route piping through ceiling and holes. Provide firestop as required. 4. Insert combustion air inlet coupling into casing. See Figure 26 or 27. 5. Slide PVC pipe into coupling. Use a hose clamp to secure the PVC pipe to the coupling. 6. Complete piping through roof. Provide flashing at roof penetration. 7. Prepare elbow assembly. See Figure 25. Insert screen into elbow socket. Secure in place with street elbow (or nipple). 8. PVC pipe can be straight through the roof or it can be offset by using up to 4-90° elbows. Horizontal PVC pipe can be up to 10 ft. (3.1 m) long in any direction from the furnace vent connection. Vertical PVC pipe can be up to 10 ft. (3.1 m) in length. FIGURE 25: Elbow Assembly 90°StreetElbow90° ElbowScreenPipetoFurnace 9. Attach elbow assembly to combustion air inlet piping. See Figure 26 or 27. Inlet must be minimum 6” (15.2 cm) above highest anticipated snow level, but no more than 24” 61.0 cm) above roof.

FIGURE 27: Combustion Air Inlet Pipe Alternate NOTE: Roof flashing, PVC pipe, PVC 90° elbows and fire stop are not supplied with the furnace. LOCATING AND CUTTING ROOF JACK OPENING To facilitate the proper installation of the roof jack, it is very important that the roof jack opening in the ceiling and roof be on the same vertical center line as the furnace flue collar. See Figures 30 and 31. Mark this location on ceiling and scribe a circle with a 5" (1.5 m) radius {10" (25.4 cm) diameter} around this mark. Cut opening for roof jack through ceiling and roof. (If furnace was installed during construction, cover furnace and flue opening to prevent debris from entering flue when hole is cut for roof jack). INSTALLING ROOF JACK IN ROOF 1. Provide protection for Vent Connector and Air-Intake Connector from damage and debris. 2. Mark Roof Jack center line on ceiling. Cut a 5" (1.5 m) radius {10" (25.4 cm) diameter} hole through ceiling. 3. Mark Roof Jack center line on roof. Cut oblong hole through roof. 4. Insert Roof Jack through roof opening. Do not secure Roof Jack to roof. 107272-UIM-B-1105 Connect Roof Jack to Furnace 1. Install Flue Shield inside Vent Connector. Push Flue Shield down until in contact with the built-in stop inside the Vent Connector. See Figures 28 and 29. Failure to install the Flue Shield may cause premature flue pipe deterioration. Damaged flue pipe can result in asphyxiation, fire or equipment malfunction. Flue Shield Furnace Vent Connector FIGURE 28: Flue Shield Installation 2. Verify gasket is around outside of Air-Intake Connector. Install new gasket if missing or damaged. 3. Pull the Roof Jack's telescoping section down onto furnace. Fully engage Roof Jack onto Vent Connector and Air-Intake Connector and compress gasket. See Figure 29. Refer to Interior Roof Jack Extension installation instructions, if applicable. 4. Align holes in Roof Jack and Air-Intake Connector. Secure Roof Jack to furnace using #10 x 1/2 - 1-1/2" (#10 x 1.3 - 3.8 cm) Type AB or Type B sheet metal screw. FIGURE 29: Roof Jack Attachment to Furnace BottomofRoofJackVentConnectorGasketFrontofFurnaceRoofJackAirIntakeConnectorOpeningforCombustionAirInletGrommet INTERIOR EXTENSIONS There is an optional 11” (43.2 cm) long interior extension that can be used to provide added interior roof jack length, if needed. To choose the proper length roof jack with or with-out the optional extension see Figures 30 and 31 and Table 9. More than one interior extension may be used to accommodate “A” dimensions up to 110” (284.5 cm). The joint where the optional interior extension connects to the roof jack must be below the ceiling. Failure to observe this requirement may result in asphyxiation, fire, or explosion NOTE: Use of an interior extension will increase the roof jack adjustable heights by the amount of the interior extension height. Unitary Products Group 107272-UIM-B-1105 Do not exceed the maximum adjustable height as listed in Table 9. These maximum heights allow an additional 1 1/2” (3.81 cm) travel before the flue pipe assembly is fully extended against the built-in stop. This provides an additional safeguard against the flue assembly being pulled from the roof jack if upward movement should occur when the home is being transported or subjected to ...
