A Make sure gas is shut off.
B Remove old Pilot Burner, including the old compres-
sion fitting.
C Match the old model number to the Cross Reference.
D Use the information in the Cross Reference to install
the Pilot Burner.
Gas Leak Test
A Make sure warning card has been removed from the pilot.
B Turn on gas supply.
C Use a gas sniffer* or paint the pipe connections upstream
of the pilot burner with a rich soap and water solution to
check for leaks. Bubbles indicate a gas leak.
D If a leak is detected, tighten the pipe connections.
E Stand clear of the main burner while lighting to prevent
injury from hidden leaks, which can cause flashback in the
appliance vestibule.
F Set the thermostat to call for heat to light the main burner.
G 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 or use a gas sniffer* to
check for leaks.
H If another leak is detected, tighten the adapter screws,
joints, and pipe connections.
I Replace the part if the leak cannot be stopped.
J Do not proceed until all gas leaks are eliminated.
* See AHRI video for proper use and considerations when
using an electronic gas sniffer

Cycle the furnace through several cycles to ensure proper
smooth light off.
The pilot flame should envelop 3/8 to 1/2 in. (10 to 13 mm) of
the igniter-sensor tip.
A Turn off the system.
B Disconnect the lead to the MV terminal on the gas control.
C Light the pilot by setting the thermostat above room tem-
perature to call for heat.
D Remove the pilot adjustment cover screw from the gas
control.
E Turn the inner pilot adjustment screw clockwise to
decrease or counterclockwise to increase the pilot flame.
F Replace the pilot adjustment cover screw and tighten firm-
ly after adjustment is complete to ensure proper operation.
NOTE: If Pilot flame is too small and cannot be adjusted to a
larger size, a larger orifice may be needed. Check application
requirements. If Pilot flame is too large and cannot be adjusted
to a smaller size, a smaller orifice may be needed. Check appli-
cation requirements.

See Cross Reference for orifice and sizes.Use the included screws to mount the Pilot Burner. Use the
Auxiliary Mounting Bracket if needed.
Position the Pilot Burner so the pilot flame is aimed at the
main burner exactly the same way as the original pilot
burner flame.

Note
This pilot replaces only Honeywell standard single-rod,
hood-style intermittent pilot burners that do not have an
integral ignition and sensing wire.
It will not replace batwing style pilot burners or pilot burn-
ers that have an integral ignition wire or standing pilot
burners.
• For batwing-style intermittent pilot burners see the
Q348U.
• For hood-style intermittent pilot burners with an inte-
gral ignition wire see the Q3451U.
• For standing pilot applications with standard hood-
style pilot burners see the Q314U.
The specifications given here do not include normal manu-
facturing tolerances. Therefore, this unit may not exactly
match the listed specifications.
This product is tested and calibrated under closely
controlled conditions, and some minor differences in
performance should be expected if those conditions are
changed.
WHEN INSTALLING THIS PRODUCT
1. Read these instructions carefully. Failure to follow
instructions can damage equipment or cause a hazard-
ous condition.
2. Check cross reference in the installation guide or box to
verify the pilot is suitable for your application.
3. Installer must be a trained, experienced service techni-
cian.
4. After completing installation, use these instructions to
check out product operation.
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 installa-
tion and perform Gas Leak Test after completion of instal-
lation.
3. Do not bend pilot tubing within 3 inches of the gas control
or pilot burner after compression nut has been tightened.
Gas leakage at the connection can result.
Follow the appliance manufacturer instructions, if available;
otherwise, use the instructions provided.

FIRE OR EXPLOSION HAZARD. CAN CAUSE
PROPERTY DAMAGE, SEVERE INJURY, OR DEATH.
Pilot flame must be positioned in the exact same posi-
tion with respect to the main burner. The screw must be
installed through the pilot hood and into the spud, so
the head of the screw is flush with the adapter. Failure
to properly orient the pilot flame and/or secure the pilot
hood may create an explosion hazard.
FIRE OR EXPLOSION HAZARD. CAN CAUSE
PROPERTY DAMAGE, SEVERE INJURY, OR DEATH.
Pilot burner flame alignment to the main burner is critical
to safe appliance operation. Carefully read all installation
instructions. Replace only those pilots listed in the
literature.
WARNING
FIRE OR EXPLOSION HAZARD. CAN CAUSE
PROPERTY DAMAGE, SEVERE INJURY, OR
DEATH.
Orifice must be the same size as the original orifice.
WARNING
FIRE OR EXPLOSION HAZARD. CAN CAUSE
PROPERTY DAMAGE, SEVERE INJURY, OR DEATH.
Check for gas leaks any time work is done on a gas
system.
WARNING
FIRE OR EXPLOSION HAZARD. CAN CAUSE
PROPERTY DAMAGE, SEVERE INJURY, OR DEATH.
Using the incorrect orifice or pilot hood can cause an
unstable pilot, too large or too small of a pilot, pilot out-
age, reduced pilot life, improper lightoff, or gas buildup.
