FUEL SUPPLY & PIPING
WARNING:
FIRE OR EXPLOSION HAZARD
• Failure to follow safety warnings exactly could
result in serious injury, death or property
damage.
• Installation and service must be performed
by a qualified installer, service agency or the
gas supplier.
• Do not store or use gasoline or other
flammable vapors and liquids in the vicinity
of this or any other appliance.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch; do not
use any phone in your building.
• Leave the building immediately.
• Immediately call your gas supplier from a
neighbor’s phone. Follow the gas supplier’s
instructions.
• If you cannot reach your gas supplier, call
the fire department.
AVERTISSEMENT :
RISQUE D’INCENDIE OU D’EXPLOSION
• Le non-respect des avertissements de sécurité pourrait
entraîner des blessures graves ou des dommages
matériels importants.
• L’installation et l’entretien doivent être effectués par
un installateur qualifié, un organisme de service ou le
fournisseur de gaz.
• N’entreposez pas ni n’utilisez de l’essence ni d’autres
vapeurs ou liquides inflammables dans le voisinage de
cet appareil, ni de tout autre appareil.
QUE FAIRE S’IL Y A UNE ODEUR DE GAZ
• N’essayez d’allumer aucun appareil.
• Ne touchez à aucun interrupteur électrique; n’utilisez
aucun téléphone dans le bâtiment.
• Évacuez l’immeuble immédiatement.

WARNING:
All piping must conform with local building codes,
or in the absence of local codes, with the most
recent edition of the National Fuel Gas Code ANSI
Z223.1 or (CAN/CSA B149.1). Failure to follow all
safety warnings could result in serious injury,
death or property damage.
This furnace may be installed with left, right, or bottom gas
entry. When connecting the gas supply, provide clearance
between the gas supply line and the entry hole in the
furnace casing to avoid unwanted noise and/or damage
to the furnace. Typical gas service hookup for this furnace
is shown in Figure 27 .
Table 10, (page 25) lists gas flow capacities for standard
pipe sizes as a function of length in typical applications
based on nominal pressure drop in the line.
IMPORTANT NOTES:
• Some local regulations require the installation of a
manual main shut-off valve and ground joint union
external to the furnace. See Figure 27 . The shut-
off valve should be readily accessible for service
and/or emergency use. Consult the local utility or
gas supplier for additional requirements regarding
placement of the manual main gas shut-off.
• Per ANSI 21.47, A 1/8-inch NPT plugged tapping,
accessible for test gauge connection, must be
installed immediately upstream of the gas supply
connection to the furnace external to the cabinet.
If local codes allow the use of a flexible gas appliance
connector, always use a new listed connector. Do
not use a connector that has previously serviced
another gas appliance.
• Gas piping must never run in or through air ducts,
chimneys, gas vents, or elevator shafts.
• Compounds used on threaded joints of gas piping
must be resistant to the actions of -liquefied
petroleum gases.
