Furnace size is listed for reference only, if available, and no calculations are performed during this inspection to determine the adequacy or efficiency of the heating system. 29 - Condition Systems are tested using normal homeowner operating controls. If pilots or circuit breakers are off at the time of the inspection, the inspector will not ignite or activate the system. You can contact the utility provider for evaluation of the heating system. 30 - Venting Fuel burning appliances exhaust the products of combustion to the exterior through vent pipes.
Vent pipes utilize caps to prevent moisture entry and to stop back drafting.
Back drafting means that the products of combustion are escaping into the home instead of venting to the exterior. Air When fires burn, they consume oxygen. Fuel that burns completely is harmless and creates only carbon dioxide. Fuel burning appliances must be provided with a constant source of fresh air for the fuels to burn properly. If air is not provided to the fire, incomplete combustion may occur which could produce carbon monoxide.
