Q4100C Hot Surface Igniter
WARNING
INSTALLATION INSTRUCTIONS
APPLICATION
Q4100C Hot Surface Igniters are designed to provide a robust
field service replacement igniter in gas fired appliances with
120 VAC silicon carbide hot surface igniters. The Q4100C
uses a 120 volt silicon carbide igniter design with long life and
high resistance to damage or burn out in the appliance.
Q4100C models include the silicon carbide igniter, bracket,
screw, and wiring accessories to adapt the igniter to the
specific appliance application. Clear instructions and cross
reference tables are provided to simplify selection of the
proper igniter and ease installation of the replacement.
BEFORE YOU START
1. Review this instruction sheet fully to assure you are
familiar with steps and information necessary to complete the installation properly.
2. Confirm the existing hot surface igniter has failed:
a. Run an appliance cycle and observe the installed
igniter.
b. If the igniter glows, the problem is not the igniter.
c. If the igniter does not glow during an ignition cycle:
(1) Unplug the igniter lead wires.
(2) Set a voltmeter's scale to 300 VAC and connect
the voltmeter to the igniter harness.
(3) Run another cycle and confirm 120 VAC power
at the harness during the warm up time.
3. If the appliance is a sealed combustion model, determine if the existing hot surface igniter ceramic is part of
the sealing of the burner box. If it is, check carefully to
determine if the replacement igniter ceramic will properly maintain the existing burner box seal.
4. Confirm the model components:
a. one silicon carbide igniter and one bracket
b. one mounting screw
c. two wire nuts
d. some models will include optional male and female
connectors
5. Confirm igniter ceramic block and bracket match original
igniter to ensure proper installation.
6. Verify connector configuration matches original igniter.
a. If provided connectors do not match existing furnace
lead wire connection, verify sufficient lead wire
length prior to cutting furnace and igniter lead wire.
INSTALLATION
When Installing This Product…
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous condition.
2. Check the cross reference tables on pages 3,4,5, and 6
to make sure the proper igniter is used for your application.
3. Installer must be a trained, experienced service technician.
4. After installation is complete, check out appliance operation as provided in these instructions.
Fire or Explosion or Electrical Shock Hazard. Can
cause severe injury, death or property damage.
1. Never install where water can flood, drip or
condense on the igniter or its controller.
2. Liquefied petroleum (LP) gas is heavier than air and
will not naturally vent upward.
– Do not operate electric switches, lights, or
appliances until you are sure the appliance area
is free of gas.
3. Disconnect power supply before beginning wiring or
making wiring connections to prevent electrical
shock or equipment damage.
4. Q4100C is not intended for use in commercial or
residential clothes dryers.
Remove the old igniter assembly
1. Turn off electrical power supply external to the appli-
ance.
2. Turn off gas supply to the appliance.
3. Set thermostat to the lowest setting or OFF.
4. Remove the appliance panel to expose the burner area.
If necessary remove the burner box panel to expose the
installed igniter.
5. Disconnect the installed igniter from the appliance wiring harness and move the wiring harness out of the way.
6. Carefully review the location of the installed igniter in the
appliance. Pay attention to where the igniter is located
relative to the burners and other parts of the appliance.
This will help confirm the location of the new igniter for
installation.

7. Locate and remove the screw(s) holding the installed
igniter or igniter bracket assembly in place. Remove the
installed igniter very carefully to avoid damaging it.
Retain the screw(s) for re-installation.
NOTE: If there is an orange rubber gasket on the original
metal bracket, carefully remove the gasket from
the original bracket and use it with the Q4100C
bracket.
Select the proper Q4100C igniter
1. Use the cross reference table to determine which igniter
models are recommended for replacement. See Table 1
on page 4.
2. Verify that the selected igniter matches the original
igniter being replaced.
Install the replacement igniter
1. Carefully position the replacement Q4100C igniter and
bracket assembly into the appliance. Position the
assembly so the existing mounting screw holes align
with the mounting holes or slots in the replacement
assembly.
2. Secure the replacement igniter bracket with the original
igniter screws.
NOTE: In some applications, the supplied shorter screw
may simplify installation.
3. Orient the replacement igniter the same way as the orig-
inal igniter was positioned and secure it. Be sure the
igniter portion does not touch the appliance or burners.
4. Use care to handle the replacement igniter only by the
ceramic block or bracket assembly.
5. Carefully route the replacement igniter lead wires away
from the burner flame and any moving parts on the
combustion air blower in the appliance.
6. Locate the appliance igniter wiring harness. Clip off the
connector and strip both wires to 1/4 in. (6 mm).
7. Use the appropriate connector to connect the igniter
lead wires to the appliance.
a. Some Q4100C models use a dedicated mate-n-lock
style connector.
(1) Snap connector into corresponding appliance
connection.
b. In some applications, the provided igniter connector
will not match the corresponding appliance connector.
(1) Use provided wire nuts to attach the igniter lead
wires to the appliance wiring harness.
(2) The igniter lead wires can be cut shorter if
desired.
(3) Strip them to 1/4 in. (6 mm) prior to attaching to
the appliance wire harness.
c. Q4100C models with stripped lead wires can use
the provided mate-n-lock style connectors.
(1) Push stripped wire end into provided metal con-
nectors until wire end is snug against the tip of
the connector.
(2) Crimp flag ends together around wire to secure
connector to lead wire.
(3) Check existing connector housing to ensure it
matches the original igniter
(4) Push metal connector into connector housing.
The connector should make an audible clicking
noise as it seats into the housing.
(5) Snap connector into corresponding appliance
connection.
Check out the installation
1. Recheck location of the igniter bracket assembly and
lead wires to assure there is no interference and that the
lead wires will not be exposed to excessive heat or moving parts when the appliance is firing.
2. Recheck the line voltage connections between the
igniter harness and the appliance wiring harness to be
sure they are secure. Assure that no bare wire is
exposed at this connection.
3. Turn the electrical power supply on, but leave the gas
supply off, and initiate a light off (call for heat) cycle.
Observe the hot surface igniter during the sequence to
confirm it gets hot and that there is sufficient clearance
between the igniter and other appliance parts. Also confirm that the lead wire routing does not interfere with
appliance operation.
4. Remove the call for heat signal.
5. Turn the gas supply on.
6. Initiate a call for heat. Observe the light off sequence
and confirm that the appliance lights properly and stays
lit once the actual gas flow starts.
7. If the appliance lights and the main flame stays stable,
remove the call for heat and allow the shut down
sequence to be completed. Repeat step 6 two more
times to assure the light off of the appliance is reliable.
8. If the appliance does not light properly, it may be necessary to adjust the location of the hot surface igniter. Turn
the gas supply off then loosen the mounting screw(s)
and make adjustments. Retighten the screw(s) and
repeat from step 5.
