Draft Hood Spillage Test

Follow the steps below to see if enough fresh air is available.

1.Close all windows and doors.

2.If you have a fireplace, start a fire. Build fire until flames are burning strongly.

3.Turn on all exhaust fans. These include exhaust fans for kitchen, bathroom, water heaters (gas or electric), etc.

4.Turn on all vented gas appliances. These include any room heaters, water heaters, clothes dryer, etc.

5.Wait ten minutes for drafts to regulate.

6.Check for draft-hood spillage at each vented gas appliance. Do this by holding a lit match two inches from the draft opening (see Figure 9). If match flame pulls toward the draft hood, there is no spillage. If match flame blows away from the draft hood, there is spillage. This is a hazardous condition. See Draft Hood Spillage, page 16.
