| Answers To Last "Test Your Knowledge" Question |
"What
Potential Safety Problems Are Present |
In The
Photograph Below?" |
Answers Below: |
Dryer vent pipe is "flex-style"
plastic. This type of vent pipe is not recommended for use due to: a). its
ability to hold lint, and b). it is made out of plastic & can burn.
Recommend using continuous smooth metal piping, as per the lower portion of the
dryer vent.
Dryer vent pipe is using a "lint
sock" in an effort to re-capture warm, moist air from the dryer and return it back
into the house. Note that the clothes dryer's fuel source is natural gas (see item
marked #5). During operation, the gas dryer will emit carbon monoxide as a
by-product of combustion, which can be blown out the lint sock, throughout the house.
For safety, this type of fuel burning appliance must be direct-vented to the
outside.
Note the separation between the clothes
dryer vent pipe (item marked #1), and the fresh-air, or make-up air vent (item marked #4).
In this case the separation is only 16-20 inches. Minnesota requires at least
a 3'-0" separation between these two types of vents, and the Uniform Mechanical Code
goes even farther and specifies a 10'-0" separation. The reason is simply this:
If the fresh-air vent is placed in too close a proximity to a vent that is
exhausting carbon monoxide (a fossil-fuel burning appliance), the carbon monoxide can be
drawn back into the house through the fresh-air vent, creating an obvious safety hazard.
