6.2 IGNITER-INJECTOR

Currently, two different types of igniters are used with Innovation Water Heaters. Heater Models
INN600, INN800 and INN1060 utilize igniter-injector part no. 58023. However Innovation Heater Model
INN1350 utilizes igniter, part no. 66023.
Since differences exist in the removal/replacement of these two igniters, separate procedures are
provided for each type. For Model INN600, INN800 and INN1060 units, refer to paragraph 6.2.1
(igniter-injector part no. 58023). For Model INN1350 units, refer to paragraph 6.2.2 (igniter part no.
66023).

6.2.1 Igniter-Injector Part No. 58023

The igniter-injector (part no. 58023) is currently used on all IN600, INN800 and INN1060 units. The
igniter-injector is located on the flange of the blower-side intake manifold located at the bottom of the
unit's heat exchanger. In addition to providing the ignition spark required to light the burner, the igniter-
injector also contains a gas injector tube which connects to the staged ignition assembly. Figure 6-1
shows the blower-side intake manifold removed from the heater and indicates the locations of the
igniter-injector, flame detector and other related components.
The igniter-injector may be hot, therefore, care should be exercised to avoid burns. It is easier to
remove the igniter-injector from the unit after the unit has cooled to room temperature. Inspect/replace
the Igniter-Injector as described below.
Figure 6-1. Blower-Side intake Manifold (With Igniter-Injector Part No. 58023)
1. Set the ON/OFF switch on the control panel, to the OFF position. Disconnect AC power from the
unit
2. Remove the side and rear panels from the unit.
3. Disconnect the cable from the igniter-injector (Figure 6-1).
4. Refer to the partial exploded view in Figure 6-1 and Figure 6-2. Using a 7/16" open-end wrench,
disconnect the compression nut securing the gas injector tube of the igniter-injector to the elbow of
the staged ignition solenoid assembly. Disconnect the staged ignition assembly from the igniter-
injector.
