suitably constructed enclosure as per AS/NZS 2918: 2001.

SAFETY INFORMATION
General:
This appliance is not intended for use by persons (including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for their safety.
For the protection of young children, install an effective fire safety screen around your fire. Always keep
children well away from the wood burner when it is alight.
Supervise young children to ensure they do not play with the appliance.
During initial burns of the appliance, ventilate the rooms well. It is recommended that babies, small
children, pregnant women and pets should not be present in the area during initial burns as this is the
firebox paint curing period.
Do not make any modifications to the unit and use it only in the manner described in the manual. Using it
in any manner not recommended by the manufacturer may result in injury or death.
Electrical connections:
As the Tommi Inbuilt wood burner is required to be permanently connected to an electrical source, an
isolating switch (wall switch) must be installed.
New circuits or modifications, if required, but be made using the services of a certified electrician only.
Ensure that the outlets you use are grounded properly, polarised and provided with fuse units.
Ensure that the isolation switch is readily accessible after installation. The wood burner must not be
located immediately below an electrical socket.
Never operate the appliance with a damaged plug or cord, or if you observe the fan unit is malfunctioning
or the heater has been damaged in any way. Call the authorised service person immediately for repairs or
making electrical or mechanical adjustments. – Isolate the electrical supply to alleviate any potential risk.
If the supply cord is damaged, the manufacturer, its service agent or a suitably qualified person must
replace it to avoid electrical hazard. Any cord similar to the original can be used.
