Constructing a Non-Combustible Floor (continued)
3.
Place a sheet of 24-gauge (minimum) galvanized sheet metal on top of the 5/8" sheet rock;
the sheet metal must cover the sheet rock completely.
4.
Place 4" thick (minimum) hollow masonry block, end to end, on top of the 24-gauge sheet metal
to make a solid foundation. Be sure to add center cross blocking to safely and adequately
support the furnace.
5.
Place a 24-gauge sheet metal pan with a 1" containment lip on top of the masonry blocks. This
will provide containment of any oil that may be spilled while working on the furnace.
6.
Position the furnace on top of the sheet metal pan; make sure you maintain the extra 12"
minimum clearance on all sides of the cabinet.
7.
Ensure that the installation adheres to all clearances from combustibles as stated at the beginning
of Section 4 in this manual.
8.
After positioning the furnace cabinet on the sheet metal pan, install 2" tall (minimum) cinder
blocks (4) under each corner of the furnace to elevate the cabinet off the sheet metal pan to
allow clearance for installation of fittings on the connector block.
