(5.6mm) clearance

from ceramic tile surface

the electrode.

Refer to the illustrations below.

• FIGURE 8 illustrates general arrangement of heater operation.

• FIGURE 9 shows the direct spark assembly.

Annual maintenance should be performed as follows:

CAUTION: Always wear protective goggles when cleaning heaters.

1. Disconnect all power sources related to the installation and close the gas supply

valve at the heater.

2. With an air hose of 20 PSI (140kPa) or less, blow off all accumulated dust and dirt.

Blow air over the ceramic tile (avoiding gasket material between tile) and

alternately into the venturi several times in succession. Be careful not to damage

gasket material between ceramic tiles. Damaging the material between the tiles

could lead to burner flashback.
