Cleaver Brooks ClearFire® Economizer CB-8466 Maintenance

As stated in the general description, the economizers are mechanically maintenance free.

A routine physical inspection of the heat transfer core area will be dependent on the temperature conditions and combustion quality within the flue gas stream.

NOTE: Ensure that the boiler is off and is cool, and that the economizer is cool before attempting to inspect or clean the fin coil(s).

On natural gas or propane fired applications, with clean exhaust conditions, physical inspection will be minimal if proper combustion at the burner is maintained.

In the unlikely event of an accumulation of dirt on the fins (i.e. a 1/16" thickness build up on the fins), the fouled finned tube area can be manually cleaned by blowing air with a lance assembly across the fins.

If high pressure air is not available, an industrial vacuum cleaner may be substituted.

If a waterside inspection shows a buildup of scale due to inadequate water treatment, descaling should be performed before resuming operation.

Investigate deficiencies in the water treatment program and correct accordingly.
