Question

Outdoor combustion air provided by a mechanical air supply system requires a supply rate not less than ______ cfm per 1,000 Btu/h of total input rating of all appliances located within the space

Answer 1

The student is asking for the supply rate of outdoor combustion air by a mechanical air system based on appliance input rating, which cannot be provided without referring to specific local codes or standards.

Step-by-step explanation:

The student is inquiring about the rate at which outdoor combustion air should be supplied by a mechanical air supply system in relation to the total input rating of all appliances within a given space. Although the actual requirement could vary based on local building codes and standards, the question does not provide the specific code or value necessary to supply the correct answer. Therefore, it's important to consult the local building codes or standards such as the International Mechanical Code (IMC) or the National Fire Protection Association (NFPA) to determine the correct supply rate of outdoor combustion air in cubic feet per minute (cfm) per 1,000 Btu/h.
