Question

A chimney is located 5 feet away from the vent connection on a furnace. The furnace manufacturer states that the vent connector must have at least" per foot of upward slope per foot of horizontal distance between the furnace and the chimney. In the distance between the furnace and the vent, what is the minimum change in elevation from where the vent connector pipe is attached to the furnace to where it connects to the chimney that is required?

Answer 1

The minimum elevation change for the vent connector pipe over a distance of 5 feet, with a required slope of ¼ inch per foot, is 1¼ inches.

Step-by-step explanation:

The student has asked about the minimum change in elevation required for a vent connector pipe from a furnace to a chimney, given a certain slope requirement by the furnace manufacturer. The manufacturer requires a minimum slope of ¼ inch per foot for the vent connector. Since the horizontal distance is 5 feet, the minimum elevation change would be 5 feet multiplied by ¼ inch per foot. Therefore, the minimum elevation change is 1¼ inches. To achieve proper ventilation and ensure safety, it's essential to adhere to these specifications. It's also a good practice to check any additional requirements that may be outlined by local building codes or the manufacturer.
