Instructions
After the installation, the flue and chimney should be warmed through gradually to prevent
cracking and the drying out of mortar between the insert and the chimney pot. This must be done
before initial use (on first firing) or after long periods without use.
We would recommend that chimneys using the following fuels are regularly cleaned and inspected
as follows:
Smokeless Fuels - at least once annually
Coal - twice per year
Wood - quarterly
Oil - annually
Gas - annually
It is essential for safety reasons that any insert to be fitted is correctly selected and is suitable for
the heating appliance being used.
