Installation considerations

When the 3WOOD is installed, check that The flue, if reused:

∙Supplies the negative pressure required for the new boiler (see the table of technical specifications on page 10);

∙is suitable for the temperature of the products of combustion, and has been calculated and constructed according to the required standards; recommended by NFPA

∙is as straight as possible, airtight, insulated and is not blocked or choked;

∙is fitted with a cleanout door

∙The heating system should be flushed, cleaned of any slime and deposits, vented and tested for water tightness.

∙The heating system should be equipped with a new expansion tank of sufficient size to handle the volume of both boilers.

∙The 3WOOD Boiler should be equipped with its own make-up water.
