CQ8000A Universal Hot Surface

Igniter Kit


The CQ8000A Universal Hot Surface Igniter Kit is designed to

provide a robust field service replacement igniter in gas fired

appliances with Norton/St Gobain 120 VAC silicon carbide hot

surface igniters. The CQ8000A uses a 120 volt silicon nitride

igniter design with long life and high resistance to damage or

burn out in the appliance. The kit includes the specially

designed silicon nitride igniter and six different bracket

configurations to adapt the igniter to the specific appliance

application along with accessory parts to allow mounting and

wiring the igniter. Clear instructions and application templates

are provided to simplify selection of the proper bracket and

ease installation of the replacement.


1. Review this instruction sheet fully to ensure you are

familiar with the steps and information necessary to

complete the installation properly, including the

WARNING section on this page.

2. Confirm the existing hot surface igniter has failed:

a. Run an appliance cycle and observe the installed


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 igniter warm up time.

3. Check the appliance construction and wiring diagram

(typically located on an appliance panel) and confirm

that the appliance does not use the hot surface igniter

as the flame sensor. Do not use the CQ8000A kit if the

existing igniter is also the flame sensor. Use an original

equipment part. The CQ8000A is not designed to be

used as a flame sensor.

4. 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 this kit will allow the proper

appliance function.

5. Confirm the kit components:

a. six brackets stamped A, B, C, D, E, and F

b. one hot surface igniter with wiring leads

c. two wire nuts and a thread forming screw

6. The CQ8000A should not be handled by the black

silicon nitride igniter. Use care to handle the CQ8000A

by the ceramic casing or the bracket.


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 table on page 4 and the tem-

plates (Fig. 1 and Fig. 2) to make sure the proper igniter

bracket is used for your application.

3. This product is intended for installation by a trained and

experienced service technician. If a service technician is

not available, the individual installing this product must

be knowledgeable in the design, construction, and

operation of the gas fired appliance being serviced.

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


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. The CQ8000A is NOT designed to replace silicon

carbide hot surface igniters in residential gas ovens or

residential clothes dryers. Use of this product in a

residential gas oven or residential gas clothes dryer

can result in severe injury, death, or property damage.

Remove the old igniter assembly

1. Turn off electrical power supply external to the appliance.

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


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.
