chimney liners

On oil fired heating equipment how can you tell if a customer really needs a chimney liner? What are some things I should look for to point them either toward getting one or not getting one. Thanks.

Conditions that prompt me to recommend a liner are lack of a serviceable liner, a the tile liner that is cracked or was poorly installed, the base of the chimney is full of masonry "crumbs", the boiler manufacturer recommends one, the brick mortar joints are disintegrated or the chimney is wet, the flue is too large for the input.

A number of things could dictate the need for a liner.

The size of the existing chimney if it's to big a liner would be prudent.

The type of chimney. If it's just an old brick chimney without a terracoda liner. A liner would be prudent.

By using an inspection mirror view the condition of the existing chimney or liner. If cracks are found or sections missing. A new liner would be prudent.

Remember, you'll also want to confirm that the flue gas temperature is 300°F or higher.

I'm sure there may be a few things I missed but this will get you started building a case to show your customer.

Your friend in the industry,

chimney liners

Here in Maine we are required by law to line any unlined chimney when replacing the boiler. The entire system must be upgraded to current codes when this happens. Oil tanks over 25 years need to be replaced, buried oil lines must be discontinued and sleeved, electrical and chimneys brought to codes, etc.
Check your local codes, you may not have any choice in the matter
