FIRE HAZARD
Failure to follow this warning could result in
personal injury, death and/or property damage.
Use wrench to hold furnace gas control valve
when turning elbows and gas line to prevent
damage to the gas control valve and furnace.
6. Use two pipe wrenches when making connections to pre-
vent gas valve from turning.
NOTE: If local codes allow the use of a flexible gas appliance con-
nector, always use a new listed connector. Do not use a connector
which has previously served another gas appliance.
7. Flexible corrugated metal gas connector may NOT be used
inside the furnace or be secured or supported by the fur-
nace or ductwork.
8,
Properly size gas pipe to handle combined appliance toad
or run gas pipe directly from gas meter or Propane gas reg-
ulator.
9. Install correct pipe size for run length and furnace rating.
10. Measure pipe length from gas meter or Propane second
stage regulator to determine gas pipe size.
Left Side Gas Supply Piping
Gas line can be installed directly to the gas valve through the hole
provided in the left side of the cabinet. See Figure 12
Right Side Gas Supply Piping
Two(2) 90 ° street elbows or two(2) 90 ° standard elbows and
two(2) close nipples are required for right side gas supply. See
Figure 12.
Piping with Street Elbows
1. Assemble the elbows so that the outlet of one(l) elbow is 90 °
from the inlet of the other. The elbows should be tight enough
to be leak proof. An additional 1/4turn will be required at the
end of step 2, see Figure 13.
2. Screw elbow assembly into gas valve far enough to be leak
proof. Position elbow assembly so that the inlet of the elbow is
at the bottom of the gas valve. An additional
1/2 turn
will be
required in step 3. Turn open end of inlet elbow to face the
right side of the furnace
(1/4
turn), see Figure 14.
3. Turn assembly an additional
1/2
turn to position inlet near the
top of the gas valve. In line with gas opening on right side of
furnace, see Figure 12 and Figure 15.

4. Gas supply line then can be run directly into opening of elbow.
Piping with Close Nipples and Standard Elbows
1. Assemble elbows and nipples similar to street elbows shown
in Figure 13.
2. Follow steps 2 through 4 Piping with Street Elbows.
FIRE OR EXPLOSION HAZARD
Failure to properly install metal gas connector
could result in personal injury, death and/or
property damage.
A flexible corrugated metal gas connector must be

of the furnace, and shall not be used inside the
furnace.
Black iron pipe shall be installed at the furnace gas
control valve and extend a minimum of 2" outside
furnace.
