WARNING
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE, SEVERE
INJURY, OR DEATH
Follow these warnings exactly.
1. Disconnect power supply before wiring to prevent
electrical shock or equipment damage.
2. To avoid dangerous accumulation of fuel gas, turn
off gas supply at appliance service valve before
starting Installation and perform Gas Leak Test
after completion of Installation.
3. Do not bend pilot tubing at the gas control or pilot
burner after compression nut has been tightened.
Gas leakage at the connection may result.
Follow appliance manufacturer’s instructions if available;
otherwise, use instructions provided below.
Location
1. Position the pilot burner for easy access, observation,
and lighting. In replacement applications, replace the
pilot burner with an identical unit and position the new
pilot burner in the same location and orientation as the
original pilot burner.
2. Mount the pilot burner on the main burner. Mounting
surfaces other than the main burner can shift, bend, or
warp as furnace expands and contracts while operating.
See Fig. 17.
3. Mount the pilot burner so the ignition flame remains
properly positioned with respect to the main burner
flame. See Fig. 18.
4. Supply the pilot flame with ample air free of combustion
products.
5. Do not impinge the pilot flame on adjacent parts. Do not
impinge the main burner flame on the pilot burner.
6. Do not expose the pilot flame to falling scale that could
impair the ignition of the main burner.
7. Do not expose the pilot burner to main burner rollout
while igniting or extinguishing.
8. Do not expose the pilot flame to drafts that push or pull
the pilot flame away from the thermocouple or
thermopile.
PILOT BURNER/GENERATOR MUST BE RIGIDLY
POSITIONED RELATIVE TO MAIN BURNER.

Connect Pilot Gas Tubing
1. Cut the tubing to the desired length and bend as
necessary for routing to the pilot burner. Do not make
sharp bends or deform the tubing. Do not bend the
tubing at the control after the compression nut has
been tightened because this can result in gas leakage
at the connection.
2. Square off and remove the burrs from the end of the
tubing.
3. Push the tubing into the compression nut clearance
hole until the tubing bottoms.
NOTE: When replacing a pilot burner or orifice, cut off
old compression fitting and replace with the
new compression fitting provided with new
pilot burner. Never use the old compression
fitting because it may not provide a gas-tight
seal. See Fig. 19.
4. While holding the tubing all the way in, engage the
threads and turn until finger tight.
5. Using a wrench, turn the compression nut one turn
beyond finger tight.
Do not overtighten
.

3. If a leak is detected, tighten the pipe connections.
4. Stand clear of the main burner while lighting to prevent
injury caused from hidden leaks, which can cause
flashback in the appliance vestibule. Light the main
burner.
5. With the main burner in operation, paint the pipe joints
(including the adapters) and gas control inlet and outlet

Ignite Pilot Burner
1. Before lighting the pilot burner, turn the thermostat to its
lowest setting. Wait for unburned gas to vent.
NOTE: LP gas is heavier than air and will not vent
upward. Smell for LP gas next to floor. If you
smell gas, shut off the main valve in the gas
piping or ON LP, at the tank. Perform Gas Leak
Test to recheck the connections.
2. Light the pilot burner according to the appliance
manufacturer instructions.
SERVICE
WARNING
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE, SEVERE
INJURY, OR DEATH
Perform Gas Leak Test anytime work is done to the
system.
Pilot Outage
1. If the pilot flame goes out during normal operation, but
is properly adjusted, recheck Location instructions in
the Installation section.
2. If all Location instructions are followed but pilot flame
continues to go out, construct shielding to protect the
pilot flame from the main burner ignition and extinction
and drafts. See Fig. 25.
Pilotstat® Safety Control Power Unit Failure
1. Make sure the pilot flame is properly adjusted.
2. Make sure the power unit connections are clean and
tight.
3. Make sure the terminal connections are clean and tight.
4. If the power unit still fails to hold in, use the W129A
Millivoltmeter to obtain the open and closed circuit
voltage generated by the thermocouple or thermopile.
5. Compare the measured open and closed circuit voltage
values to Acceptable Range Charts in the W129A
Manual.
6. If a W129A Millivoltmeter or other meter is not available,
replace the thermocouple of thermopile. If this does not
correct the condition, replace the power unit.
Thermocouple Or Thermopile Performance
Thermocouples and thermopiles require proper temperature
differential between the hot-junction (tip) and cold-junction
(base) to provide satisfactory operation of millivoltage gas
controls. Thermocouples and thermopiles perform less
effectively when exposed to excessive cold-junction or hotjunction temperatures.
Excessive cold-junction temperatures can be caused by heat
radiation from adjacent surfaces or high ambient air
temperatures. Excessive cold-junction temperatures can be
eliminated by shielding the pilot flame, see Fig. 25, or
constructing a baffle to direct secondary air over the pilot
burner base.
Excessive hot-junction temperatures can be eliminated by
proper pilot flame adjustment. To adjust pilot flame, see the
instructions in the Startup and Checkout section.

M3303.AI
Pilot Turndown Test (30 mV Pilotstat® Safety
Control Systems)
The Pilot Turndown Test assures that the pilot flame ignites
the main burner within four seconds from the time gas
reaches the main burner. In this test, the pilot flame is just
sufficient enough to hold in the Pilotstat® power unit or just
above the point of flame extinction (whichever occurs at a
higher pilot gas flow rate).
1. With the pilot and main burner operating, shut off the
main burner by either lowering the thermostat
temperature setting or turning the gas control knob to
the PILOT position.
NOTE: If using a Honeywell W129A Millivoltmeter,
turn the pilot gas adjustment screw until the
thermocouple open circuit voltage is 2 mV,
omit steps 2, 3, and 4 and proceed with
step 5.
2. Tu rn the pilot gas adjustment screw clockwise until the
pilot begins to decrease in size. Then turn the pilot gas
adjustment screw clockwise 1/4 turn at a time (waiting
one minute between each turn to allow the
thermocouple to cool) until safety shutoff power unit just
drops out, causing safety shutdown.
3. Tu rn the pilot gas adjustment screw counterclockwise
slightly.

4. Relight the pilot burner. The power unit should hold in.
5. Tu rn the gas control knob to the ON position and set
the thermostat temperature setting above room
temperature. The main burner should light within four
seconds without flame rollout. If not, check the pilot
burner Location instructions in the Installation section
and repeat the Pilot Turndown Test.
6. Readjust the pilot burner flame. Refer to the instructions
in the Startup and Checkout section.
Effective Ignition Test (750 mV Systems)
The Effective Ignition Test assures that the pilot flame ignites
the main burner within four seconds from the time gas
reaches the main burner. In this test, the pilot flame is just
sufficient to open the main gas valve.
1. Light the main burner according to the appliance
manufacturer’s instructions and allow to burn at least
five minutes.
2. Remove one thermostat lead (TH) at the gas control
terminal.
3. Using the pilot gas adjustment screw, decrease the pilot
flame until it begins to pull away from the thermopile.
Allow the thermopile to cool for one minute.
4. Temporarily jumper the thermostat terminals (TH) on
the gas control.
5. If the main burner ignites, reduce the pilot flame by
turning the pilot adjustment screw 1/4 turn at a time
until the valve fails to pull in. Allow the thermopile to
cool at least one minute between each reduction in the
pilot flame level.
6. Increase the pilot flame just enough to pull in the gas
control main valve.
7. Jumper the thermostat terminals. The main burner
lights within four seconds and without flame roll-out. If it
does not, check the Location instructions in the
Installation section and repeat steps 1 through 6.
8. If main burner still does not light, replace the thermopile
and repeat steps 1 through 6.
9. Remove the jumper to shut off the main burner.
10. Readjust the pilot burner flame. See the instructions in
the Startup and Checkout section.
11. Reconnect the thermopile lead and make sure all
connections are correct and the system is functioning
properly.
