Details
Step 11 — Install Gas Piping
Installation of the gas piping must be in accordance with local
building codes and with applicable national codes. In U.S.A., refer
to NFPA 54/ANSI Z223.1 National Fuel Gas Code (NFGC). In
Canada, installation must be in accordance with the CAN/CSA
B149.1 and CAN/CSA B149.2 installation codes for gas burning
appliances.
This unit is factory equipped for use with Natural Gas fuel at ele-
vations up to 2000 ft (610 m) above sea level. Unit may be field
converted for operation at elevations above 2000 ft (610 m) and/or
for use with liquefied petroleum fuel. See accessory kit installation
instructions regarding these accessories.
NOTE: Furnace gas input rate on rating plate is for installation up
to 2000 ft (610 m) above sea level. The input rating for altitudes
above 2000 ft (610 m) must be derated by 4% for each 1000 ft
(305 m) above sea level.
NOTE: Installation of this furnace at altitudes above 2000 ft
(610 m) shall be made in accordance with the Listed High Alti-
tude Conversion Kit available with this furnace.
For natural gas applications, gas pressure at unit gas connection
must not be less than 5 in. wg (1246 Pa) or greater than 13 in. wg
(3240 Pa) while the unit is operating (see Table 3). For liquefied
petroleum applications, the gas pressure must not be less than
11 in. wg (2740 Pa) or greater than 13 in. wg (3240 Pa) at the unit
connection (see Table 4).
The gas supply pipe enters the unit at the burner access panel on
the front side of the unit through the long slot at the bottom of the
access panel. The gas connection to the unit is made to the 3/4 in.
FPT gas inlet port on the unit gas valve (see Table 5).
Manifold pressure is factory-adjusted for NG fuel use. Adjust as
required to obtain best flame characteristics.
Manifold pressure for LP fuel use must be adjusted to specified
range (see Table 6). Follow instructions in the accessory kit to
make initial readjustment.
GAS SUPPLY LINE
The gas supply pipe enters the unit adjacent to the burner access
panel on the front side of the unit, through the grommeted hole.
The gas connection to the unit is made to the 3/4 in. FPT gas inlet
port on the unit gas valve.
Table 7 lists typical 3/4 in. NPT (National Pipe Thread) field sup-
plied pipe fittings required for Thru-Base gas supply, starting from
the unit gas valve (see Fig. 38).
Pipe gas supply into 90 degree elbow item 15 (see Table 7)
through the hole in the unit basepan.
For typical 3/4 in. NPT field-supplied fittings without Thru-Base
gas supply, requirements starting from the unit gas valve, omit
items 14 and 15 from Table 7 and pipe gas supply into the tee. See
Fig. 39.
Table 7 — Typical 3/4 in. NPT
Field Supplied Piping Parts
Install a gas supply line that runs to the unit heating section. Refer
to the NFPA 54/NFGC or equivalent code for gas pipe sizing data.
Do not use a pipe smaller than the size specified. Size the gas sup-
ply line to allow for a maximum pressure drop of 0.5 in. wg
(124 Pa) between gas regulator source and unit gas valve connec-
tion when unit is operating at high-fire flow rate.
The gas supply line can approach the unit in 2 ways: horizontally
from outside the unit (across the roof), or through unit basepan.
Observe clearance to gas line components per Fig. 40.

CAUTION
EQUIPMENT DAMAGE
Failure to follow this caution may result in equipment damage.
When connecting the gas line to the unit gas valve, the installer
MUST use a backup wrench to prevent damage to the valve.
