outdoors, do not allow the inlet of the pipe to become
blocked. If the furnace is operated without adequate
air for combustion, the flame roll-out switch will open,
turning off the gas supply to the burners. This indicates
that a serious problem with the burners has occurred
and must be corrected immediately. Only a licensed
HVAC technician can reset this switch.

local code official or the National Fuel Gas Code to
make sure you will be in compliance with supplying
adequate air for combustion. By erecting new walls,
it is sometimes possible to inadvertently restrict the
furnace’s air supply. You can find more information
about supplying combustion air in the NFGC, which is
available at many libraries.

The furnace is designed to have certain clearances to
combustible items such as wood, paper, etc. Some types
of insulation are combustible. If your furnace is installed
in an attic, near unfinished walls, or in other insulated
space, keep area surrounding the furnace free of insulating
material.
SOURCES OF CORROSION
It is known that certain common household chemicals can
cause heat exchanger corrosion if the vapors are pulled into
the furnace’s burners The following is a list of chemicals
that should not be used or stored near the furnace.
