Can dryer vents really pose that great of a danger? Your
dryer’s lint screen usually collects only about 75% of the lint generated by the
dryer – the rest passes along through the dryer vent. According to the Consumer Product Safety
Commission, as many as 15,000 fires start in the laundry room every year when
lint from clothes dryers builds up and catches fire. Those fires result in up
to 19 deaths, 310 injuries and more than $84 million in property damage every year.
DRYER LINT IS EXTREMELY FLAMMABLE
The local building code specifies that the maximum length of
dryer ducting is twenty-five feet minus
five feet for every 90 degree bend. Yet
the typical effective length of the dryer duct assembly here at Glen Iris Lofts
exceeds 40 feet – which is 18 feet or
70% longer than is permissible by code.
WHAT YOU CAN DO If
your dryer ducts have never been cleaned, you should either clean them yourself
or have them professionally cleaned immediately. This is especially true if you happen to
have noticed that it takes longer than it used to for your clothes to dry. If you notice any condensation dripping from
your dryer duct or if you hear even a faint ‘whistle’ coming from the duct
while your dryer is running, stop the
dryer immediately and have a professional assess your situation, as these
are warning signs that typically precede a dryer vent fire.
DO IT YOURSELF (Requires
two people) If you are the handy type and
you have a friend who can lend a hand, you can clean them yourself by
disconnecting your dryer and moving it to the side so that the duct wall inlet
is plainly visible. Then, using an electric
leaf blower (do not use any gas powered tools inside your home) blow air into
the duct, forcing lint build-up to exit through the outside vent. You may also use a Shop-Vac’s blower mode to
do the same thing. The reason that you
need another person to help is because it’s important that you verify that lint
exits through the vent when air is forced through. If it doesn’t, you may have only made the
problem worse by creating a more concentrated obstruction somewhere along the
length of the duct.
PERMANENT SOLUTION Once you have a clean dryer duct, you need to
install (or have installed) an auxiliary, motorized dryer booster fan. These devices are installed in-line along the
dryer duct and increase the velocity of the air that’s passing through, which
is the only permanent solution to this problem the way our lofts are
constructed. These usually range in price anywhere from
$125 to $350, depending on quality and features. For instance, some models can sense decreased
air flow inside the vent and alert on this condition).
DRYER BOOSTER FAN
Since a friend helped me install an in-line booster fan in
my loft’s dryer vent, I cannot personally provide any contractor references,
but it’s a job most handymen could handle without too much difficulty and the Blog will be happy to post any contracting
references any homeowner may have – just send a recommendation to gil@go.to and we will share your recommendation
with your neighbors.
IT'S YOUR PROBLEM Some might think that this defect is something that the
Association might want to weigh in on, but I can almost assure you that they
have their hands full - as they have had for the past eight years - repairing a
multitude of more complex (and costly to remedy) construction defects as it is. In any event, since the ducting is located
inside your unit, you will be told it’s your problem - never mind the fact that
when this results in a fire (which it will, eventually, if left uncorrected) it
will be everyone’s problem.
And don’t forget to thank Jerry Miller for a job not-well done the next time you see him
(or you can ask Kit to pass the message along for you)! ;-)

The final allowable distance also involves factors like vent type, dryer model, and exhaust material. If anybody is less than certain their dryer vent is safe, I will be happy to evaluate your system and give you all the details you need to make an informed decision. I don't do this commercially, there is no 'pitch', and I have no vested interest in any outcome other than the safety of our community. (Read: free of charge and no bullshit).
