FIGURE 1 – TYPICAL GAS PIPING
c. Manual Shutoff Valve at Natural Gas Meter
or Propane (LP) Gas Tank
Normally, natural gas is ON when you turn
shutoff parallel to gas pipe. Gas is OFF when
you turn shutoff 90° from gas pipe. Some valves
require a wrench or other tools.
2. ELECTRICAL SHUTOFF DEVICES
In an emergency, you may not be able to reach both
of your electrical shutoff devices. Therefore, you
must know how to turn off electricity using either
one of them. Here are two types of electrical shutoff
devices:
a. There should be an electrical shutoff 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.
SECTION 4 • TURNING OFF FURNACE IN
AN EMERGENCY
WARNING
Have a qualified installer, service agency or gas
supplier teach you location and operation of
gas and electrical shutoff devices. Ask them
any questions you have about this section. If
you don’t turn off your furnace in an emergency
damage, injury or death could result.
To turn gas control furnace switch OFF, switch
it to “OFF” position. Use this same procedure
when you leave a vacation home vacant and do
not want the furnace to operate.
b. Manual In-Line Shutoff Valve in Gas Supply
Line
This valve is next to furnace. Figure 1 shows a
typical installation.
Normally, gas is ON when you turn the shutoff
valve handle parallel to gas pipe. Gas is OFF
when you turn handle 90° from gas pipe.
1. GAS SHUTOFF DEVICES
In an emergency, you may not be able to reach all
the gas shutoff devices. You must know how to
turn off gas using any one of the three manual types:
a. Manual Shutoff Switch on Gas Control
Gas control location is behind the middle
access panel on the right side. See Lighting and
Shutdown Instructions in Section 5 for more
informantion.
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.
