Under what circumstances should a draft hood be utilized?

A draft hood should be utilized whenever a vent pipe connects to equipment to ensure proper venting and safe operation. The primary function of a draft hood is to help stabilize the draft within the venting system, allowing for a consistent flow of combustion gases away from the appliance and reducing the risk of backdrafts. This is essential for safe appliance operation, as it helps to prevent harmful gases from accumulating in the cooking area.

Using a draft hood is particularly important for appliances that burn gas, as these appliances produce combustion byproducts that need to be effectively vented outside. Without a draft hood, there can be issues related to insufficient draft, leading to potential carbon monoxide buildup and inefficient appliance performance. Therefore, it is a critical safety device that should be in place any time there is a connection between the appliance and the venting system, not just when new equipment is being installed or during maintenance activities.
