Yunca recommends that competent trades persons carry out all installations (e.g. a
NZHHA Registered Installer), to obtain maximum performance and safe, efficient
heating.

A consent is required and we suggest you check with local building inspectors as by-laws
do vary from area to area. Also notify your Insurance Company that a solid fuel heater
has been installed.
