GAS PIPING INSTALLATION

GAS PIPE INSTALLATION

GAS SUPPLY AND PIPING

GAS SUPPLY

THIS FURNACE IS EQUIPPED AT THE
FACTORY FOR USE ON NATURAL
GAS ONLY. CONVERSION TO LP GAS
REQUIRES A SPECIAL KIT AVAIL-
ABLE FROM THE DISTRIBUTOR.
FAILURE TO USE THE PROPER CON-
VERSION KIT CAN CAUSE FIRE,
CARBON MONOXIDE POISONING,
EXPLOSION, PROPERTY DAMAGE,
PERSONAL INJURY OR DEATH.

See the conversion kit index supplied
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 facto-
ry-specified or approved parts. In the
commonwealth of Massachusetts,
installation must be performed by a
licensed plumber or gas fitter for appro-
priate fuel.

IMPORTANT: Connect this furnace only
to gas supplied by a commercial utility.

IMPORTANT: A U.L. recognized
fuel gas and CO detector(s) are recom-
mended in all applications,
and their installation should be in accor-
dance with the detector manufacturer’s
recommendations and/or local laws,
rules, regulations or customs.

GAS PIPING (SEE FIGURE 15)

Install the gas piping according to all
local codes, state codes and regulations
of the utility company, whichever holds
jurisdiction.

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 manual gas
valve must be adequate in size to
prevent undue pressure drop and
never smaller than the pipe size to
the combination gas valve on the fur-
nace. Refer to Table 2 for the recom-
mended pipe size for natural gas and
Table 3 for LP gas pipe sizes.

IMPORTANT: It is permissible to run
flexible gas connector inside the unit to
a piece of black pipe. If local codes

WARNING

allow the use of a flexible gas appliance
connector, always use a new listed con-
nector. Do not use a connector which
has previously serviced another gas
appliance. Massachusetts law limits flex-
ible gas connectors to a maximum of
36”.

Install a ground joint union outside
the cabinet to easily remove the con-
trol valve assembly. Install a manual
shut-off valve in the gas line outside
the cabinet. The valve should be readi-
ly accessible to turn the gas supply on
or off. Install a drip leg in the gas supply
line as close to the furnace as possible.
Always use a pipe compound resistant
to the action of liquefied petroleum
gases on all threaded connections.

IMPORTANT: When making gas
pipe connections, use a back-up
wrench to prevent any twisting of the
control assembly and gas valve. Do
not overtighten the connection.

Any strains on the gas valve can
change the position of the gas ori-
fices in the burners. This can cause
erratic furnace operation.

IMPORTANT: ENSURE that the fur-
nace gas control valve not be sub-
jected to high gas line supply pres-
sures.

DISCONNECT the furnace and its
individual shut-off valve from the gas
supply piping during any pressure
testing that exceeds 1/2 PSIG (14”
W.C.) (3.48 kPa).
