nstructions
These instructions are for the fitting of inserts into existing pots.
The sketch shows the insert fitted to an existing pot as a typical example. If a new pot is being
installed with insert, refer to the separate fitting instructions for the particular pot.
Inspect the existing chimney pot and the new insert and confirm they are undamaged. Ensure
the insert is suitable for use with the existing chimney pot, flue system and the type of fire
installed.
For red terracotta chimney pots, mix the mortar with a red coloured dye. Apply a bead of mortar
around the top face rim of the chimney pot and fit the insert in place. For a non-symmetrical
insert, align it with the chimney pot and/or the chimney stack and ensure it is vertical. Any
exposed mortar at the joint should be smoothed and angled downwards to allow rain to run
away.
Use a smoke test to check for leakage and to ensure that the insert is working correctly. Close
the appliance and warm the chimney flue with a blowlamp or similar heating device for
approximately ten minutes. Put smoke pellets in the appliance firebox (or bottom of the
chimney or the appliance recess) and light. Close the appliance when smoke has formed and
allow the smoke to make its way up the chimney.
