How do you check the draft of a vent-connected appliance?

To determine how to check the draft of a vent-connected appliance correctly, consider the safe and effective methods available. The most reliable way to assess draft involves utilizing a tool designed for measuring pressure differences, which helps to verify that the appliance is venting properly.

While observing flames or using smoke pellets might give some indication of venting performance, these methods are less precise and could lead to misinterpretation of the draft condition. Observing the flames is subjective and can vary due to several factors. Likewise, using smoke pellets might not provide a clear measure of the actual draft pressure and can introduce other variables into the environment.

In contrast, a digital manometer provides an accurate and quantifiable measurement of the draft in the flue or vent. This tool measures the pressure within the venting system, allowing for a definitive assessment of whether the appliance is venting correctly and safely.

Therefore, when checking the draft of a vent-connected appliance, the best practice is to use appropriate equipment, like a digital manometer, as it enables technicians to ensure proper operation and safety of the appliance.
