Installation Instructions
This section describes how to install and set up your fire.
Before you start:
Ensure that all packing items are removed (read any warning labels carefully) and retain all packing for possible
future use.
Before connecting the appliance, check that the supply voltage is the same as that stated on the appliance.
CONNECTIONS REQUIRED IN ADVANCE OF INSTALLATION
Electrical Connection
Please ensure a 230V /16A power socket is located within 1 m of the product.

4
Water Connection
Please ensure a water connection is located within 1m of the product. The water connection should be one of
the following:
A male ¾ inch BSP connection (same as a standard supply for a washing machine)
A male ½ inch BSP connection (Fig. 5.1)
Both the water and electrical connections should be accessible during product installation so that the
connections can be made to the product easily.
BUILDING THE PRODUCT SURROUND/ENCLOSURE
This product can be built into a wall, surround or structure. Please take note of the product dimensions (Fig. 1)
and build your wall, surround or structure accordingly. Suitable clearance should be provided to allow the
product to be installed easily.
Fig. 1
MODEL
Mistero 500
508 mm
Mistero 1000
1017 mm

5
You are required to leave a minimum of 400 mm from the base of the fuel bed to any shelf/enclosure above
the product (Fig. 2).
This will allow enough space above the product to allow the flame effect to form fully and not to be obstructed.
When determining a location for the product, ensure that the unit will not be susceptible to drafts, vents, ceiling
fans and other air currents. Similar to a candle, large movements of air will affect the unit’s ability to create and
maintain the flame effect. If the desired location is susceptible to significant air movement, i.e. air vents, the
different installation options illustrated in Fig. 2 can be used.
VENTILATION: VERY IMPORTANT!!!
This product needs free air ventilation from underneath to operate correctly. These are slots on the underside
of the product to allow this free air through the product. The free ventilation helps keep the electronic
components cool and allows the mist to rise and leave the product. Please see Fig. 4 for an example of the
required ventilation. Please take note of the requirement for a ventilation opening on the shelf where the
product sits, to allow a clear path for the air to get to the product (Fig. 4).
M500 Free Ventilation Area: Minimum 210 cm2.
M1000 Free Ventilation Area: Minimum 420 cm2.

6
If the ventilation openings are covered, for example by a ventilation grill, the effective ventilation, as mentioned
above, will be reduced. So in that case there needs to be created extra ventilation! This must be taken into
account in advance, so that the minimum requirements for ventilation are maintained!
WATER CONNECTION
It is recommended that you consult a qualified plumber to ensure a safe and secure installation.
Two adaptors have been supplied with the product to connect the ¼ blue PVC pipe of the product to mains
water (Fig. 5.1). Either the white ½ inch or the grey ¾ inch adaptor can be used to connect the product to the
mains. For reference, the ¾ inch adaptor is the same connection used on most washing machine supplies. Once
the correct mains water connection has been installed, follow the steps below to connect your product to the
water supply.
1. With the water supply turned off, connect the correct adaptor to the main water supply (Fig. 5.1).
2. Position the water filter (Fig. 5.5) in a suitable location. This will need to be accessed for future
replacement. The two fixing clips can be used to fix the filter to a solid surface, if required.
3. Using a sharp knife or blade, cut two lengths of the blue PVC pipe. One length (Fig. 5.2) should be long
enough to travel from adaptor at the main supply to the ball valve (Fig. 5.3). The second length (Fig. 5.4)
should be long enough to travel from the ball valve to the inlet of the filter. When cutting the pipe, ensure
that the end of the tubing is cut square to prevent leaking.
4. Insert the cut pipe into the fittings, ensuring each one is pushed in fully. About 12 mm of the end of the pipe
should be inserted into each fitting. When inserting pipe into the filter, take note of the flow direction on the
filter and ensure the pipe from the main supply is fitted to the inlet of the filter.
5. Following the same steps above, cut a length of pipe (Fig. 5.6) from the outlet of the water filter to the ball
valve which has been supplied already connected to the product (Fig.5.7).
6. Before connecting the pipe to the ball valve on the product, flush out the newly plumbed pipe by opening
the valve and allowing water to flow. This is to prevent any debris from the installation from entering the
product. Once the piping has been flushed out, connect the pipe into the ball valve on the product.
7. Before fully installing the product, inspect all water connections by opening each of the valves in turn and
ensuring that no leaks are present.
Water Connection –Additional Information
Water Pressure: the water pressure on the appliance should be between 8Bar (800 Kilopascals) and 0.5Bar (50
Kilopascals). Where required, use a pressure reducing valve.
If the product is being supplied from a header tank, a head of at least 2 metres must be maintained above the
product.

7
ELECTRICAL CONNECTION
Plug the fire into a 16amp/230 Volt outlet. Be sure to have access to the plug after installation to allow for
disconnection. Ensure that the supply cable exits at the back of the fire at the right or left hand corner to suit
your supply socket location and is not trapped under the fire such that it might cause it to be damaged.
The appliance can be connected to the fixed wiring of the premises through a suitable connection box
positioned adjacent to the appliance. This electrical installation must be carried out by a competent electrician
and be in strict accordance with the current I.E.E. regulations for Electrical Equipment in Buildings.
The electrician can remove the supplied plug by the following:
1. Lift off the top plate and put switch ‘A’ into the off position (Fig. 27)
2. Ensure that the appliance is unplugged.
3. Lift off the access cover by removing the retaining screw (Fig. 6A).

8
4. Unscrew and remove the Live, Neutral and Earth wires (Fig. 7A).
5. Unscrew the cable clamp (Fig. 7B) and remove the supply cord.
6. The electrician can then connect the wire from the appliance to the connection box (by following the steps
above in reverse) ensuring that it incorporates a double pole isolating switch, having a contact separation of at
least 3 mm. Brown –Live (L), Blue –Neutral (N) and Green/Yellow –Earth (E).
INSTALLING THE PRODUCT INTO SURROUND/ENCLOSURE
Once your enclosure has been built to the required dimensions and plumbing and electrical connections have
been installed, follow the steps below to install your product.
1. Sit the product on the constructed base, ensuring the cable and pipes are accessible and not caught under
the product.
2. Ensure that the product is at the correct height to suit the installation and ensure it is adequately level. This
can be done by adjusting the adjustable feet with a flat head screwdriver (Fig. 8).
The levelness of the product can be verified by checking the on-board spirit level which is located on the
metal base towards the back of the fire (Fig. 9).
3. Once the product is at the correct height and is level, centre the product within the opening.

9
4. With the product in its final position, remove the top plate and screw the product to the surround using the
four fixing holes shown in Fig. 11.
COMMISSIONING/INITIAL PRODUCT START-UP
Connecting the Receiver/Tethered Remote
Insert the 3.5 mm jack of the Bluetooth receiver into the socket at the back of the appliance (Fig. 12). It is
important to ensure that the jack is pushed fully into the socket. Failure to fully insert the jack will prevent the
product from functioning correctly. The receiver has a cable length of 1.4 m which will allow you position it
anywhere around the product. If you prefer to hide it, the receiver can be placed inside the surround/wall.
Please ensure that the receiver is not enclosed in metal, concrete or any other dense material, this will affect the
signal from the remote control.

10
Initial Product Start-up
In some cases, where low water pressure exists or where the product is being fed by the pump accessory, the
product may start to fill with water but not complete its first fill within the allowed filling time period. It is
recommended that each sump is primed with 600-700 ml of water before switching on the product for the first
time. If measuring this amount of water is not possible, the water guide in the sump moulding can be used for
reference. Fill the sump with water until the top surface of the water is level with the top of the water guide. See
Fig. 13 for details on the location of the water guide.
MULTIPLE PRODUCT INSTALLATION (DAISY CHAINING)
Power and Water Connections
Both the M500 and M1000 products can be installed side by side to elongate the flame effect. When supplying
power to multiple products, ensure the maximum wattage of the combined products does not exceed the rated
capacity of the MCB in the circuit. The water supply to multiple products should be constructed in a manifold
style configuration and sized appropriately for the number of units that are being installed so a consistent volume
water and pressure is being supplied to each unit.
Multiple Product Installation
Follow steps 1-4 ‘Installing the Product into Surround/Enclosure’ to fit the first product. It is important that the
first product is orientated so that the side of the product with the slots is left free and not connected to first end
of the installation (Fig. 19).

11
1. When the first product is installed and securely fixed, prepare the second product by unscrewing the
joining screws (Fig. 20A) and screwing them into the opposite side of the metalwork (Fig. 20B). Please
note, these screws should not be fully tightened and 5-10 mm of thread should be left protruding from
the edge of the product.
2. Fit the second product beside the first product, ensuring the protruding screws of the second product
engage with slots of the first product (Fig. 21).
3. Ensure the second product is at the correct height to match the first product and ensure it is adequately
level. This can be done by adjusting the adjustable feet with a flat head screwdriver (Fig. 8).

12
The levelness of the product can be verified by checking the on-board level (Fig. 9).
4. Tighten the screws of the second product so that it joins tightly with the first product.
Additional product scan be fitted to the second product by following steps 1-4 above.
Multiple Product Control
Each product has been supplied with its own link wire in order to form a hardwire link between the multiple
products. Please follow the instructions below to link multiple products together.
1. Identify the ‘master’ product in the installation. It should be the product on the left hand side of the
installation.
2. Connect the Bluetooth receiver to this product (M500 –Fig. 22A, M1000 –Fig. 23A).

13
This will be the only Bluetooth receiver in the installation and will control the rest of the products in the
installation. In an installation of both M500 and M1000 products, a M500 receiver (Fig. 12) should be
connected to the ‘master’ product.
3. In installations where a M500 is the ‘master’ product, connect the M500 link wire to the connector in
the plastic top cover (Fig. 22B). In installations where a M1000 is the ‘master’ product, connect the
M1000 link wire to the 3,5 mm jack which is housed in the plastic (Fig. 23B).
4. Feed the wire through the hole in the metalwork and into the housing of the next product in the
installation (Fig. 24).

14
5. For a M500, plug the link wire into the 3.5 mm jack housed in the plastic (Fig. 25). For a M1000 plug the
link wire into the 3.5 mm jack housed in the plastic on the left hand side module (Fig. 26).
6. Repeat steps 3-5 above in order to connect subsequent products in the installation.
Once set up, any command sent to the first product will be sent to all subsequent products. Flame height
control and sound level control of the master product is matched for all subsequent products. If individual
flame height control is required, this can be done by using the on board flame height controls on the
product (Fig. 27).

15
Additionally, the software of the product has been designed in such a way that when multiple products are
connected to a main switch, products can be manually switched off and when switched back on they will
operate in the same state as before they were switched off.
