Installation & Operation Manual

5 Vertical direct venting (continued)

Vertical termination – optional concentric vent: Models 400 - 601 Only

￿WARNING

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.

CAUTION

DO NOT use field-supplied couplings

to extend pipes. Airflow restriction will

 

 

occur.

6.

Install the rain cap and the small diameter pipe assembly

 

into the roof penetration assembly. Ensure the small

 

diameter pipe is fastened tightly into the rubber adapter

 

for #CVK3007 installations.

NOTICE

Do not allow insulation or other materials

to accumulate inside the pipe assembly

 

when installing through the hole.

for proper pipe attachment.

8. Operate the appliance through one (1) heat cycle to ensure

combustion air and vent pipes are properly connected to

the concentric vent termination connections.
