In addition to the standard water heater design discussed in the main service handbook, the C3 Technology design also includes:

•A LDO (Lint Dust and Oil) screen over the combustion air intake

•A Flame Arrestor

•A combustion chamber Thermal Cut Off (TCO) limit

An additional tool for these products might be a vacuum cleaner with both blowing and vacuuming capabilities. Also include the long, narrow crevice accessory.

LDO SCREEN (LINT, DUST, OIL) SCREEN(S)

An easy to clean screen designed to minimize lint, dust and oil based contaminants from being drawn into the “Flame Arrestor” along with make up – combustion - air. There may be one or two of these screens. The LDO screen must be installed with the arrows on the right and left side facing up to function properly. (The arrows are located on two mounting tabs on each side of the screen).

Service:

Inspect the LDO screen(s) regularly. Clean or wash as necessary.

Pulling the tab located in the middle of the screen will remove the screen. Reinstall the clean screen by inserting the end tabs into the jack with the arrows pointing up.

Possible Service issues associated with a blocked screen:

•Poor combustion – yellow flame, possible sooting

•Pilot outage resulting from a lack of oxygen

•Pilot outage resulting from to increased combustion chamber temperature below the main burner. This may open the automatic reset, thermal cut off switch (TCO).
