Typical Spark Module
Top Burner Spark Ignitors
Spark ignition units have an electrode for each burner
(2 on an open burner, 4 on a sealed burner). When any
of the burner valves are turned to the LITE position, the
spark switch on the valve connects supplying voltage to
the spark module. This activates the module that
produces the spark at the ignitor electrode to light the
burner.
1. Turn off gas and power supply to unit.
2. Check wiring diagram to verify all terminals and wire-
connections are correct and tight.
3. Disconnect high voltage spark ignitor leads from
terminals on the spark module.
4. Attach one meter lead to a good ground and the
other lead connected to ignitor terminal wire. If
continuity is indicated, ignitor or wire is shorted to
ground. If no continuity is indicated, proceed to next
step.
5. Attach one lead to ignitor terminal wire and the other
lead to the tip of ignitor. If no continuity is indicated,
ignitor or wire is open. If continuity is indicated ignitor
is good.

on all modules
To avoid risk of electrical shock, personal injury or death,
disconnect power and gas supply before servicing,
unless testing requires it.
6. If erratic spark is a problem, remove control panel,
darken the room and observe the operation. Broken
insulation on wire's may produce arcing to ground
not visible in the daylight.
Thermostat Spark Switch and Spark Switch
Valve Test
Each spark switch is connected in parallel with spark
ignition circuit. One terminal on each switch is
connected to 120 VAC, "COMMON" while the other
*
terminal connects to the "MANUAL" on the spark
module. Terminal "N" of the module connects to the
common or neutral side of the AC line. The spark switch
is located on the stem of the top burner valve.
1. Turn off gas and power supply to unit.
2. Check wiring diagram to verify all terminals and wire-
connections are correct and tight.
3. Attach meter leads to switch terminals.
4. Turn switch to LITE position. Meter should indicate
zero ohms or closed contacts. Infinite ohms or open
contacts should be indicated in all switch positions
except LITE .
