Installation Instructions
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 to the mains supply, check that the supply voltage is the same as that stated on the appliance.
INSTALLATION
This appliance has been designed to be housed in separately designed structures – e.g. furniture, fireplace surrounds etc.
To incorporate this appliance into another structure, it should be securely fitted, following these guidelines:
ESSENTIAL VENTING
A suitable air vent is essential to ensure that air can circulate into the appliance - otherwise the Opti-myst flame
eect will not operate correctly. A cavity of at least 100cm² is required for this air vent. This pathway for air must
not be obstructed. For examples of air vents see (Fig 10) The air vent should be free from drafts.
3. Construct an opening for the appliance LxWxH 390x205x170mm (+3-0mm)
4. Ensure that there is sucient room to thread through the mains cable
5. A cavity of at least 100cm² is required to ensure air can circulate into the appliance. - See ESSENTIAL VENTING.

Filling the Water Tank
1. Place Water Tank in sink and remove cap (turn anti-clockwise to open)
2. Fill Water Tank with filtered tap water only. This is necessary to prolong the life of the flame and smoke eect
producing unit. The water should be filtered through a conventional domestic water filter unit and the filter should
be replaced regularly. Distilled water must not be used.
3. Screw the cap back on – do not overtighten.
4. Place the Water Tank in the Sump, with the tank cap facing down and the flat side of the tank facing outward
