Installation Instructions
This section describes how to set up your fire.
BEFORE YOU START
1. Ensure that all packing items are removed (read any warning labels carefully) and retain all packing for
possible future use e.g. in the event of moving house or returning the appliance to your supplier.
2. Before connecting the appliance, check that the supply voltage is the same as that stated on the heater.
Installation into a Fireplace Mantle
●When installing this appliance into a fireplace mantle please ensure that you choose a mantle suitable for
your appliance (Fig 17). There is to be an air vent at the front of the fireplace mantle of at least 100cm2.
It is essential to ensure that air can circulate into the appliance – otherwise the Opti-myst flame effect will
not operate correctly. This pathway for air must not be obstructed
●Remove the 4 spacing brackets on the front of the appliance (Fig 18)
●Slide the appliance into the fireplace mantle fully from the back ensuring that it is sitting in the center of
the mantle. Using suitable screws (not supplied) screw fix the appliance in place (Fig 19)
●Be sure to position the fireplace within 1m of a power outlet (Fig 20)
Installation into a wall or recess cavity
●Note the product dimensions in Fig 1 and build a suitable structure for the appliance to fit into within 1m
of a power outlet (Fig21). Using suitable screws (not supplied) screw fix the appliance in place
●Note the venting slots in the appliance. There are located at the front base and under the appliance
●Build the wall up against the appliance using the spacing brackets as a guide.
●There is to be an air vent at the front of the structure of at least 88cm2. It is essential to ensure that air can
circulate into the appliance – otherwise the Opti-myst flame effect will not operate correctly. This pathway
for air must not be obstructed. For examples of air vents in a wall or recess cavity see Fig 22 and Fig 23.
PLEASE ENSURE CHILDREN DO NOT CLIMB, HANG OR STAND ON THIS PRODUCT.
WARNING: THE APPLIANCE IS PROVIDED WITH A TIPPING RESTRAINT, THIS RESTRAINT IS NOT A
SUBSTITUTE FOR PROPER ADULT SUPERVISION. THIS RESTRAINT MAY PROVIDE PROTECTION

Depending on how cold it is outside, this could mean the room is still cold when you have to get out of bed, or
mean that its been warm for half an hour before it needed to be. Adaptive Start means that if you select 21ºC
at 7am, the heater will turn on exactly when it needs to in order to meet this target, running for shorter periods
of time when the weather is mild, and ensuring the room is nice and warm in the winter.
The Adaptive Start function will automatically activate when you use the Timer Mode.
