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.

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 .
6. Connect the other end of the tubing to the gas control
according to the gas control manufacturer instructions.

Install Thermocouple or Thermopile
Push-in Design
1. Insert the thermocouple or thermopile tip into the hole
or barrel provided beneath the pilot burner. See Fig. 20
and 21.
2. Push in firmly until the thermocouple or thermopile is
locked into place.
Attachment Nut Design
1. Insert the thermocouple or thermopile tip into the hole
or barrel provided beneath the pilot burner. See Fig. 21.
2. Engage the attachment nut threads and tighten until the
thermocouple or thermopile is locked into place.

Install Bleed Gas Tubing (if used):
1. Route the bleed gas tubing from the bleed tapping on
the gas control to the pilot burner.
2. Push the clip into place as shown in Fig. 22.
3. Insert the bleed gas tubing until 3/8 inch (10 mm) of the
tubing is above the pilot burner bracket. The tip of the
bleed gas tubing must not extend into the pilot flame.

Install Q314 “A” Mounting Bracket Adapter
To convert the mounting bracket on a Q314 from a “B”
mounting bracket to an “A” mounting bracket, install the “A”
mounting bracket adapter to the pilot burner mounting
bracket. Then install the pilot burner to the main burner. See
Fig. 16.
Change Insert Orifice (See Fig. 23)
1. Disconnect the pilot tubing from the pilot burner and
remove the insert orifice. Light force may be required to
remove the orifice.
2. Cut off the old compression fitting.
NOTE: When replacing an orifice, cut off the old
compression fitting and replace with a new
compression fitting. Never use an old
compression fitting because it may not provide
a gas-tight seal. See Fig. 19.
3. Square off the end of the pilot tubing and remove all the
burrs.
4. Insert the new compression nut over the pilot tubing
and slide out of the way.
5. Insert the new orifice into the pilot burner and push the
pilot tubing into the pilot burner until it bottoms.
6. While holding the tubing all the way in, slide the
compression fitting into place and engage the threads.
Turn until finger tight.
7. Using a wrench, tighten the compression fitting one turn
beyond finger tight.

STARTUP AND CHECKOUT
Perform Gas Leak Test
WARNING
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE, SEVERE
INJURY, OR DEATH
Check for gas leaks with soap and water solution any
time work is done on a gas system.
Gas Leak Test
1. Ensure that the gas supply is turned on at the appliance
service valve.
2. Paint the pipe connections upstream of the pilot burner
with rich soap and water solution. Bubbles indicate a
gas leak.
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
with rich soap and water solution.
6. If another leak is detected, tighten the adapter screws,
joints, and pipe connections.
7. Replace the part if the leak cannot be stopped.
Adjust Pilot Flame
The pilot flame should envelop 3/8 to 1/2 in. (10 to 13 mm) of
the thermocouple or thermopile tip. See Fig. 24 To adjust the
pilot flame:
1. Remove the pilot adjustment cover screw from the gas
control.
2. Turn the inner pilot adjustment screw clockwise to
decrease or counterclockwise to increase the pilot
flame.
3. Replace the pilot adjustment cover screw and tighten
firmly after completing adjustment to ensure proper
operation.
