4. Install Combustion Air Pipe

Attach a field-supplied combustion air pipe to the concentric side of the CVA.

Be sure to provide enough combustion air piping to pass through the roof and provide the minimum clearance of 12 inches between the combustion air intake and the exterior surface of the roof. This clearance may need to be increased to allow for snow accumulation.

Be sure to maintain the minimum clearance of

12 inches between the exhaust pipe termination and the combustion air intake.

5. Install CVA Assembly

Place the CVA assembly through the roof and verify that all minimum clearance requirements as specified in these instructions are met. Secure the CVA assembly to the ceiling with corrosion resistant sheet metal screws through the mounting brackets.

6. Attach CVA Assembly to Unit

Attach the exhaust pipe to the unit’s combustion exhaust. Using an additional combustion air pipe, connect the unit’s combustion air supply intake to the combustion air connection on the CVA.

Be sure to include the required tee’s with drip legs and clean-outs.
