1. Attach factory-supplied flexible coupHng to furnace
combustion-air inlet connection and secure with stain­
less steel hose clamp. Ensure that factory-supplied,
perforated metal combustion-air disc is installed in the
flexible coupling.
2. Working from furnace to outside, cut PVC pipe to
required length(s).
3. Deburr inside and outside of pipe.
4. Chamfer outside edge of pipe for better distribution of
primer and cement.
5. Clean and dry all surfaces to be joined.
6. Check dry fit of pipe and mark insertion depth on pipe.
NOTE: AU. pipe should be cut, prepared, and preassembled
before any joint is permanently cemented.
7. After pipes have been cut and preassembled, apply
—4—
generous layer of PVC primer to pipe fitting socket and
end of pipe to insertion mark. Quickly apply PVC
cement (over primer) to end of pipe and fitting socket.
Apply cement in light, uniform coat on inside of socket
to prevent buildup of excess cement. Apply second coat
of cement to end of pipe.
8. While the PVC cement is stfil wet, insert pipe into
socket with a 1/4-turn twist. Be sure pipe is fuUy
inserted into fitting socket.
9. Wipe excess cement from joint. A continuous bead of
cement is visible around perimeter of a properly made
joint.
10. Handle pipe joints carefully until cement sets.
11. Support piping every 5 ft (minimum) using perforated
metal hanging strap. Slope combustion-air and vent
pipes toward furnace a minimum of l/4-in./lineal ft
with no sags between hangers.
