NOTICE

Instead of cementing the smaller pipe to

the rain cap, a field-supplied stainless steel

 

screw may be used to secure the two (2)

 

components together when field disassembly

 

is desired for cleaning (see FIG. 4-12).

6.Install the Y concentric fitting and pipe assembly through the structure’s hole.

Do not allow insulation or other materials to NOTICE 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. 4-13 using field-supplied metal strapping or equivalent support material.

NOTICE

Ensure termination location clearance

dimensions are as shown in FIG. 4-7.

 

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, field-supplied

 

SDR-26 PVC (D2241) pipe for CVK3003

 

and standard schedule 40 PVC for CVK3007.

Figure 4-12Rain Cap to Vent Pipe Alternate Assembly

 

Do not extend dimension D* more than 60

 

inches (see FIG.’s 4-10 and 4-11).

 

If assembly depth needs to be reduced,

NOTICE

dimension D can be as short as possible.
