Leylandii didn't burn well? Your stove needed to be replaced.

Leylandii often don't burn well in a closed stove. If you've limited
volume above the firebed and don't have separately controllable top air,
then you'll not burn the vapourised resin. As well as not burning
usefully, it'll give you big creosote buildups in the flue and the risk
of a chimney fire.
