4.A GAS AND ELECTRICAL SHUT-OFF
DEVICES
1.
GAS SHUT-OFF DEVICES
In an emergency, you may not be able to reach
all the gas shut-off devices. You must know
how to turn off gas using any one of the three
manual types:
a. Manual Shut-off Switch on Gas Control
Gas control location is behind the access
panel on the right side. See Lighting and
Shutdown Instructions in Section 5 for
more information.
b. Manual In-Line Shut-off Valve in Gas
Supply Line.
This valve could be next to furnace.
Figure 1 shows a typical installation.
Normally, gas is ON when you turn the
shut-off valve handle parallel to gas pipe.
Gas is OFF when you turn handle 90° from
gas pipe.
c. Manual Shut-off Valve at Natural Gas
Meter or Propane (LP) Gas Tank.
Normally, natural gas is ON when you turn
shut-off parallel to gas pipe. Gas is OFF
when you turn shut-off 90° from gas pipe.
Some valves require a wrench or other
tools.

ELECTRICAL SHUT-OFF DEVICES
In an emergency, you may not be able to reach
both of your electrical shut-off devices.
Therefore,you must know how to turn off
electricity using either one of them. Here are
two types of electrical shut-off devices:
a. There should be an electrical shut-off
device located on or immediately adjacent
to the furnace.
b. There should be a separate circuit breaker
or fuse serving only the furnace located in
the main circuit breaker or fuse panel.
Know its location and make sure this device
is clearly identified.
In an emergency you
must
know how to turn off gas
and electricity. Find out how
before
the emergency.
WARNING
Should overheating occur or the gas
supply fail to shut off, shut off the manual
gas valve to the furnace before shutting off
the electrical supply. Failure to do so can
cause a fire or explosion which could result
in damage, injury of death.
