NOTICE
Do not allow insulation or other materials to accumulate inside the pipe assembly when installing through the hole.
WARNING
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. Ensure small diameter pipe is bottomed and cemented in the Y concentric fitting for #CVK3003 installations and fastened tightly into the rubber adapter for #CVK3007 installations.
8.Secure the assembly to the structure as shown in FIG.
NOTICE | Ensure termination location clearance | |
dimensions are as shown in FIG. | ||
| ||
| If assembly needs to be extended to allow | |
NOTICE | ||
sidewall thickness requirement, the two (2) | ||
| ||
| ||
| pipes supplied in the kit may be replaced by | |
| using the same diameter, | |
| ||
| and standard schedule 40 PVC for CVK3007. | |
| Do not extend dimension D* more than |
Figure
| 60 inches (see FIG.’s | |
| If assembly depth needs to be reduced, | |
NOTICE | ||
dimension D can be as short as possible. | ||
