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 9, a-i 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 de-
terioration of the heat exchanger.
Chemicals used to during construction may cause
damage to the COLLECTION CELL.
DO NOT USE SEMI-RIGID METALLIC GAS CONNEC-
TORS (FLEXIBLE GAS LINES) WITHIN THE FURNACE
