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 crevasse 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).
