Light a Pilot Light
It's cold in here!
Let's say you're arriving at a cabin for a
weekend in the country. You're ready to enjoy a
much needed get-away--but the gas furnace and water
heater aren't. They've been shut down in
order to conserve fuel, and if you don't want to
freeze your tail off, you'd better know how to
start them up again. This 2torial supplies the
basic guidelines on how to light standard pilot
lights for gas appliances. But be careful--you
don't want anything to go boom in the night!

There are many different models of gas
appliances (i.e., furnaces and water heaters) out
there, so some of you may have difficulty applying
these guidelines to your unit. Always get the
advice of a plumber or licensed professional if
you're not sure how to proceed.
Most units operate using a gas supply valve
which is linked to a thermostat. Gas is distributed
on-demand to a burner, where it's ignited by a
pilot light. (See Keywords for these terms).
Find the appliance
- Locate the appliance you want to
start up. They're generally located in a closet
attached to a central hallway, in a utility room
or basement, or next to the kitchen.
Read the instructions printed on the
unit. Most gas appliances will post printed
instructions on how to turn on the gas and light
the pilot. Follow these to the letter!
Discover if it's operating
- Listen for sounds coming from the
appliance. You may hear a rushing or rumbling
sound. Put your hand next to the wall of the
unit (careful!). It may feel warm.
- Locate a removable panel on the front
side, usually near the bottom. Peer into the
peep hole there, if there is one, or remove the
panel and look for a blue flame. These signs--a
rumbling noise, a warm wall of the unit wall,
the presence of a blue flame--all indicate that
the appliance is already on. If this is the
case, the pilot is already lit--you're done! Now
locate the thermostat and adjust it to your
desired level of comfort.
Okay, you've tried all the above, and there's no
heat, no blue flame, no rumbling noise. Therefore
the appliance is definitely turned off.
Follow the steps below carefully to turn the
appliance on again safely.
Be
familiar with the parts

Connected to the unit, will be a pipe with an
on/off valve that looks something
like a faucet. This is the main gas line. Modern
gas lines have a length of flexible pipe connecting
the main gas line to the appliance. The gas is
turned off when the handle on the main gas line is
perpendicular to the pipe. A one-quarter turn (90
degrees) of the faucet handle makes it parallel to
the pipe opens the gas line to the appliance.
There's usually only one way to turn the handle.
- Look at the control knob on the unit.
Usually it's a round knob with lettering that
indicates three positions: off, pilot,
and on. These three settings are critical
to our operation. A marker arrow should be
located somewhere next to the knob on the
appliance itself. This marker indicates which
setting you've selected on the knob.
- Locate the pilot light fixture. It's
usually a small metal pipe that originates at
the gas line and is located next to the burner
unit. Sometimes it looks like metal cylinders,
with a small pipe that looks something like a
candle wick. It's usually located on the right
side of the burner as you'e looking at it from
the front. If you're lucky, it may even be
labeled.
- Notice that you'll have access to the
pilot light fixture either from the wall of
the appliance (through a hole or removable
panel), or by reaching up from the bottom.
Sometimes there'll be just enough access to put
in a match held with your fingertips.
Have your equipment handy. Flashlight,
matches, and wrench should all be within easy
reach. Having another person around to assist is a
great idea.
Turn the gas on

In this step, you're switching on the main gas
line, so that gas feeds into the appliance. You
should sniff around for the sweetish smell of
gas--none should be escaping from any valves ito
the air around you. If you do smell gas,
turn the gas off and call a plumber or licensed
professional.
- Start with the off position of the
knob aligned next to the marker arrow
Then turn the gas valve one-quarter turn
(90 degrees) so that it's parallel to the pipe.
This turns the gas on, making it available to the
appliance. Use a wrench to help turn the valve
handle if necessary. Remember you only need
one-quarter turn, and usually the handle only goes
in one direction.
Turn the pilot on

- Turn the control knob so that the
word pilot lines up next to the marker
arrow. (Have a match or lighter ready.) You
should hear a small hiss. That's a flow of gas
going to the pilot light fixture.
- Light a match (or a butane lighter on
its highest setting) and hold it next to the
pilot fixture. Hold the flame as close to the
fixture as possible for a few seconds. The flame
should jump onto the fixture. If nothing
happens, return the knob to off and check
your pipelines to be sure all lines are open.
Light the burner

Once you've established a flame on the pilot
fixture, turn the control knob on the appliance
from pilot to on.
- Set the thermostat as high as
possible. Check the burner unit on the
appliance. A blue flame should "jump" across the
gap from the pilot to the burner. The flame will
continue to move around the burner unit until
the burner is fully lit.
- When you've determined that the burner is
fully lit, turn down the thermostat to your
desired setting. You're all set!
If you're sure all the valves in the gas line
are turned on and the pilot refuses to light
(sigh), some professional service may be
required. Turn the main valve off and call the
local gas company or a plumber. You may need to
pile on some extra clothes, boil water on the
electric stove or stoke a big fire in the fireplace
while you wait for the repairman to come in the
morning. But at least you'll be happy knowing you
didn't blow up the house.
Troubleshoot the pilot that won't
light
- Let's say you've lit the pilot, but
nothing happens to the burner when you
turn up the thermostat. If so, check the
control knob. Make sure that you've turned the
on setting of the control knob next to
the marker arrow on the unit. Sometimes a knob
can become loose or wobbly and not read
accurately.
- If you still don't get any response, then
turn the control knob to off and wait
about five minutes. Sometimes it takes a while
for natural gas to charge the line fully. After
five minutes, turn the knob to pilot and try
lighting again.
- Having difficulty locating the pilot
fixture? Look at where the gas line enters
the appliance (usually at the control knob).
Find a small pipe that leads out from the main
gas line and follow it around. You're looking
for a small fitting with some kind of a nozzle,
wick, or cylindrical attachment located within
an inch or so of the burner.
Some units have a start button--usually
colored red and located next to the control knob.
Push the start button after turning the control
knob to pilot. Keep the button pushed in
while holding the flame to the pilot fixture.
Release the button when the flame jumps to the
pilot.
