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 Installation Codes.
• Some local codes 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 7 (page
16).
• The manifold pressure must be set to the appropriate
value for your installation. Refer to the Manifold
Pressure Adjustment section ( page 18
) for
adjustment instructions.
• Gas piping must never run in or through air ducts,
chimneys, gas vents, or elevator shafts.
• Compounds used to seal joints on gas piping must
be resistant to the actions of LP propane gas.
• The main gas valve and main power disconnect to
the furnace must be properly labeled by the installer
in case emergency shutdown is required.
• An 1/8 inch NPT plugged tap must be installed in
the gas line immediately upstream of the gas supply
connection to the furnace for use when measuring
the gas supply pressure. The plug should be readily
accessible for service use.
• A drip leg should be installed in the vertical pipe
run to the unit ( Figure 7 ).
This unit only has right side gas entry. When connecting
the gas, provide clearance between the gas supply line
and the entry hole in the unit’s casing to avoid unwanted
noise and/or damage to the unit. A typical gas service
hookup is shown in
Figure 7 .
Table 15 (page 28) lists gas pipe capacities for standard
pipe sizes as a function of length in typical applications
based on nominal pressure drop in the line.
