YOUR FURNACE'S
FILTER - WHAT IT
DOES
The filter in your furnace takes the
lint and dust out of the air that
passes through it. This keeps dirt
particles from getting into the mov-
ing parts of the furnace, where they
could cause serious damage. It
also keeps the dirt from circulating
through your home.
As the filter continues to collect
these particles, it becomes clogged
and no longer allows enough air to
circulate through the furnace. If this
happens, the heat exchangers and
blower motor could overheat; a
potentially dangerous situation. It is
very important to keep the air filter
clean! Never operate your furnace
without a suitable air filter.
FREQUENCY OF
CHECKING FILTERS
Clean or change your furnace's fil-
ter at least every three months. If
you need to replace a filter, replace
it with the same type or contact a
qualified service person.
If your home is new, you should
check the filter every week for the
first four weeks after you begin to
use the furnace, and then at least
every three weeks after that, espe-
cially if the system runs constantly.
Should overheating occur,
or the gas supply fail to
shut off, shut off the main
manual gas valve to the
furnace before shutting off
the electrical supply.
TYPICAL GAS PIPING
Turn off all electrical
power to the furnace if
service is to be performed.
