• Ne pas tenter d'allumer aucun appareil.
• Ne toucher à aucun interrupteur électrique;
n'utiliser aucun téléphone dans le bâtiment.
• Évacuer l'immeuble immédiatement.
• Appeler immédiatement le fournisseur de gaz en

GAS SUPPLY & PIPING
All gas piping must be installed in compliance with local
codes and utility regulations. In the absence of local codes
the gas line installation must comply with the latest edition
of the National Fuel Gas Code (ANSI Z223.1) or (CAN/
CGA B149.1 or .2) Installation Codes.
• Some local regulations require the installation of a
manual main shut-off valve and ground joint union
external to the furnace. 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. See Figure 22 (page 22).
• 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.
• The main gas valve and main power disconnect to
the furnace must be properly labeled by the installer
in case emergency shutdown is required.
• Flexible gas connectors are not recommended for
this type of furnace but may be used if allowed by
local jurisdiction. Only new fl exible connectors may
be used. Do not reuse old fl exible gas connectors.
• A drip leg should be installed in the vertical pipe
run to the unit. See Figure 22.
Table 12 (page 37) lists gas fl ow capacities for standard
pipe sizes as a function of length in typical applications
based on nominal pressure drop in the line.
The furnace may be installed for either left or right side 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 hookups are shown in Figure 22.

Leak Check

Failure to follow safety warnings exactly could
result in serious injury or property damage.
Never test for gas leaks with an open fl ame.
Use a commercially available soap solution
made specifi cally for the detection of leaks
to check all connections. A fi re or explosion
may result causing property damage, personal
injury or loss of life.
