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. 4-10).

 

 

 

6.Install the Y concentric fitting and pipe assembly through the structure’s hole from an inside wall.

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 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.

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 standard schedule 40 PVC for

 

CVK3007. Do not extend dimension D*
