WARNING
THIS FURNACE IS EQUIPPED
AT THE FACTORY FOR USE ON
NATURAL GAS ONLY. CONVER-
SION TO LP GAS REQUIRES A
SPECIAL KIT AVAILABLE FROM
THE DISTRIBUTOR. FAILURE TO
USE THE PROPER CONVER-
SION KIT CAN CAUSE FIRE,
CARBON MONOXIDE POISON-
ING, EXPLOSION, PROPERTY
DAMAGE, PERSONAL INJURY
OR DEATH.
See the conversion kit index sup-
plied with the furnace. This index
identifies the proper LP Gas
Conversion Kit required for each
particular furnace.
IMPORTANT: Any additions, changes
or conversions required for the furnace
to satisfactorily meet the application
should be made by a qualified installer,
service agency or the gas supplier,
using factory-specified or approved
parts.
IMPORTANT: Connect this furnace
only to gas supplied by a commercial
utility.
IMPORTANT: A U.L. recognized
fuel gas and CO detector(s) are rec-
ommended in all applications, and their
installation should be in accordance
with the manufacturer's recommenda-
tions and/or local laws, rules, regula-
tions or customs.
GAS PIPING
Install the gas piping according to all
local codes and regulations of the utili-
ty company.
If possible, run a separate gas supply
line directly from the meter to the fur-
nace. Consult the local gas company
for the location of the manual main
shut-off valve. The gas line and man-
ual gas valve must be adequate in
size to prevent undue pressure drop
and never smaller than the pipe size
