For proper procedures, exceptions, selection methods, and alternate
methods to the following checklist, see the ASHRAE Standard 62.2 - 2007.
 All components shall be designed and installed per manufacturers’
requirements and local codes.

The system shall have at least one supply or exhaust fan with associated
ducts and controls.  Local exhaust fans are allowed to be part of an
exhaust ventilation system.  Outdoor air ducts connected to the return
side of an air handler are allowed to be part of a supply ventilation
system if manufacturers’ requirements for return air temperature are
met. The airflow required by this standard refers to the delivered
airflow of the system as installed and tested using a flow hood, flow
grid, or other airflow measuring device.

An intermittent mechanical exhaust system shall be designed to operate
as needed by the occupant. Control devices shall not impede occupant
control in intermittent systems.

A vented range hood, or appliance-range hood combination, is required if
exhaust fan flow rate is < 5 kitchen ACH.

If net exhaust flow exceeds allowable limit, net exhaust flow shall be
reduced or compensating outdoor airflow provided. Net exhaust flow
requirement is exempted if no atmospherically vented combustion or
solid-fuel burning appliances are located inside the pressure boundary. 

Electric condensing dryers equipped with condensate drain need not be
vented.

Fans exempted from this requirement include HVAC air handlers and
remote-mounted fans (i.e., fans outside habitable spaces and with > 4
ft. ductwork between fan and intake grills). 

Carbon monoxide detectors shall be placed according to NFPA 720 and be
hard-wired with a battery back-up function.

Manufacturer filter media boxes designed to accomplish these purposes
meet these requirements.
