WARNING

When using the alternate screw assembly method, drill a clearance hole in the rain cap and a pilot hole in the vent pipe for the screw size being used. Failure to drill adequate holes may cause cracking of PVC components, allowing combustion products to be recirculated. Failure to follow this warning could result in personal injury or death.

Do not operate the appliance with the rain cap removed or recirculation of combustion products may occur. Water may also collect inside the larger combustion air pipe and ﬂow to the burner enclosure. Failure to follow this warning could result in product damage or improper operation, personal injury, or death.

7.Install the rain cap and small diameter pipe assembly into the Y concentric ﬁtting and large pipe assembly from an outside wall. Ensure small diameter pipe is fastened tightly into the rubber adapter for #CVK3007 installations.

8.Secure the assembly to the structure as shown in FIG. 4-11 using ﬁeld-supplied metal strapping or equivalent support material.
