INSTALLATION LOCATION
CAUTION
!
To prevent shortening its service life, the furnace
should not be used as a “Construction Heater” during
the finishing phases of construction until the require-
ments listed in item 8, a-g of the safety section of this
publication have been met. Condensate in the pres-
ence of chlorides and fluorides from paint, varnish,
stains, adhesives, cleaning compounds, and cement
create a corrosive condition which may cause rapid
deterioration of the heat exchanger.
WARNING
!
SUPPORT FURNACE PROPERLY
DO NOT hang the downflow/ horizontal furnace from
a structure, or surface, by any integral part or fas-
tener of the furnace. The furnace was not designed to
support itself in this manner.
