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.
IMPORTANT NOTES:
• 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
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 flexible connectors may
be used. Do not reuse old flexible gas connectors.
• A drip leg should be installed in the vertical pipe
run to the unit. See
Figure
Table 10 (page 36)
lists gas flow 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
