Remodeling Don’ts – Venting

There is a lot of venting that takes place in homes. From bath fans to remove moisture, hood fans in your kitchen, attic fans to lower the temperature in your attic, venting takes place. Those of you who have gas appliances like stoves, water heaters, and furnaces may be  familiar with exhaust vents aka flues. These are important in ridding your house of byproducts of combustion. Vents and flues are made to run vertically.

A lot of these vents have standard sizes. That doesn’t mean that some folks refrain from the urge to be   ‘creative’.

Here somebody combined their bathroom vents into a plumbing vent stack. Note the elegant downward angle allowing any of the bath fans to blow sewer gas into the others.

Here is a really really dumb vent idea. This guy combined his dryer vent with the exhaust flue of his water heater. The problem here is that the dryer air can blow out the water heater flame. Filling your laundry room with gas in really not a good idea. Vent4-1

Here is a vent using a shoe box as a ‘boot’, which is the technical term for the sheet metal pieces that go from round to rectangular for attaching grilles. I don’t even want to think about what this guy used for a grill outside.

Speaking of grilles, here is somebody who has no understanding of cross ventilation, having the supply and return air grilles next to each other. That little corner gets great climate control while the rest of the room gets nothing.
