6 G6RA, G6RK Service Manual
Downflow Warning (G6RK Models):
The design of the downflow furnace is certified for natural or
propane gas and for installation on non-combustible flooring.
A special combustible floor sub-base is required when
installing on a combustible floor. Failure to install the sub-
base may result in fire, property damage and personal injury.
The special downflow sub-bases are factory supplied
accessories, part numbers 902677 and 902974. When the
furnace is installed on a factory or site-built cased air
conditioning coil, the sub-base is not necessary. However,
the plenum attached to the coil casing must be installed such
that its surfaces are at least 1" from combustible construction.
A gas-fired furnace installed in a residential garage must be
installed so the burners and the ignitor are located not less
than 18 inches (457 mm) above the floor, and the furnace
must be located or protected to avoid physical damage by
vehicles.
