Installing Your Unit

Tips on how to install your unit

What you need to know about installing a wood heater.

Taking the time to ensure your wood heater is installed correctly will make sure you have a sustainable heat source for years to come.

Clearances to combustibles for units will be outlined in the literature provided by the manufacturer of your unit. These include side clearances, rear wall clearances and clearances required if installing the unit into a corner. It will also dictate the hearth requirements for the unit including thickness and projection in front of and beside the firebox door opening.

The flue used for the unit will also need to comply with the Australian Standard AS/NZS 2918.

Drop boxes and wall and floor penetration kits must be used when penetrating sections of your home.

A minimum fuel height of 4.6 metres from the hearth to the flue cap is required. At the flue cap you must have at least 3 metres clearance to your adjacent roof, and minimum 6 metres horizontally to any nearby structures or buildings.

Not meeting these requirements could cause the fire to burn incorrectly, cause a smoke nuisance, or could create a fire hazard.

State and local councils may have different requirements about who can install the unit or the certification required. Check the statutory requirements in your area before starting any work. To get the best advice ask your local AHHA member.

Can I install the heater myself?

Most heaters burn better with 3 or 4 logs rather than 1 or 2. Logs should not be too big – 2 to 4kg for 40 cm logs is typical.

Does the size of my heater matter?

Always buy the right size heater. A heater that is too large for an area will have to be turned down too often and too small a heater can result in over-firing, shortening the life of the heater.
