Dimplex Opti-myst Inset Fire
Models: Atherton ATH20 / Bellemont BLL20 / Flagstaff FLG20 / Pomona POM20
Thank you for choosing a Dimplex electric fire
General Information
The fire incorporates a flame effect, which can be used with or without
heating, so that the comforting effect may be enjoyed at any time of the year.
A fan heater can provide heating in cold weather. A distance of 1 metre (3
feet) must be maintained between the front of the heater and any surrounding
furniture, overhanging curtains or other obstructions.
To reduce heat loss and to prevent any chimney up draft affecting the
operation of your inset fire we recommend they the chimney flue is sealed off.
Always ensure that the appliance is sitting on a level surface. Before
connecting the appliance, check that the supply voltage is the same as that
stated on the appliance.
Only use filtered water in this appliance. Once installed, never move this
appliance or lay it on its back, without draining the water from sump and
water tank. The water tank, sump, sump lid, tank cap and air filters must be
cleaned once every week, particularly in hard water areas. If you intend not
using the appliance for longer than a week, drain the water from sump and
water tank and dry the sump.
Please note: Used in an environment where background noise is very low,
it may be possible to hear a sound which is related to the operation of the
flame effect. This is normal and should not be a cause for concern.
The sump and the water tank in this product are treated with a biocidal
product, Silver Biocide in order to control harmful or unwanted organisms.
This conforms with the latest relevant ISO standard. Do not drink the water
from the sump or from the water tank(s)

Installation Instructions
This heater must be used on an AC ~ supply only and the voltage marked on the heater must correspond to the supply voltage. Before switching on, please read the safety warnings and operating instructions. Please retain this user’s guide for future reference
Before installing this appliance in an existing chimney, we recommend that;
- You have your chimney cleaned by a competent chimney sweep.
- You block off the chimney flue.
This procedure is important for the efficient operation of the heating unit
and will also reduce heat loss up the chimney.
Ensure that all packing items are removed (read any warning labels carefully).
Retain all packing for possible future use e.g. in the event of moving or
returning the appliance to your supplier.
Installing the Appliance;
- Clean the area where the fire will be installed e.g remove ash residue from an existing fireplace.
- Hold the fire by the sides of surround and gently manoeuvre into position.
- Plug the fire into a 13amp/240 volt outlet. Ensure that the supply cable is not trapped under the fire such that it might cause it to be damaged.
- Ensure that the draft excluder (rubber strip) is fitted to the channel on the base of the product.
Connecting the Transducer
- Gently lift out the fuelbed and carefully set aside. (Fig 3)
- Remove the water tank by lifting upwards and outwards. (Fig 4)
- Remove the nozzle by unclipping and lifting upwards and outwards. (Fig 5)
- The transducer will be inside the sump. Remove from its bag.
- Place the Transducer unit into the sump and make the connection.
- Locate the tab on the Transducer unit into the moulded recess in the base of the sump (Fig 6)
- Ensure that the cable does not obstruct the Transducer disc. To prevent the cable becoming pinched between the nozzle and the sump, place the cable in the slot in the wall of the sump. (Fig 7)
Filling the Water Tank
- Gently lift out the fuelbed and carefully set aside.
- Remove the water tank by lifting upwards and outwards.
- Place the water tank in sink and remove cap, Anti-clockwise to open. (Fig 8)
- Fill tank with filtered tap water only. This is necessary to prolong the life of the flame and smoke producing unit. The water should be filtered through a conventional domestic water filter unit and the filter should be replaced regularly.
- Screw the cap back on, do not over tighten.
- Return the tank to the sump, with the tank cap facing down
- Gently place the fuelbed back into position.
When the water tank is empty, the flame and smoke effect shuts off, you will hear 2 audible beeps and the digital display will display

Thermal Safety Cut-out
A thermal safety cut-out is incorporated in the fan heater to prevent damage
due to overheating.
This can happen if the heat outlet was restricted in any way. If the cut-out
operates, unplug the heater from the socket outlet and allow approximately 10
minutes before reconnecting. Before switching the heater back on remove any
obstruction that may be restricting the heat outlet, then continue normal
operation.
CAUTION: In order to avoid a hazard due to inadvertent resetting of the
thermal cutout, this appliance must not be supplied through an external
switching device, such as a timer, or connected to a switch that is regularly
switched on and off by the utility.
Getting the Desired Flame Effect
-
Using the manual controls or the remote control choose a setting between F1 and F6.
F1 being the lowest setting and F6 being the highest setting. -
Generally the flames appear more realistic when the flame control is turned down.
-
Give the flame generator time to react to changes you may make.
-
The fire will use less water if the flame effect is set to a lower level.
-
Do not tilt or move the fire while there is water in the tank or sump.
-
Make sure that the fire is on a level floor.
WARNING: KEEP BATTERIES OUT OF REACH OF CHILDREN
- Swallowing may lead to serious injury in as little as 2 hours or death, due to chemical burns and potential perforation of the oesophagus.
- If you think batteries might have been swallowed or placed inside any part of the body seek immediate medical attention
- Examine devices and make sure the battery compartment is correctly secured, e.g. that the screw or other mechanical fastener is tightened. Do not use if the compartment is not secure.
- Dispose of used button batteries immediately and safely. Flat batteries can still be dangerous.
WARNING
KEEP OUT OF REACH OF CHILDREN
Swallowing can lead to chemical burns, perforation of soft tissue, and death.
Severe burns can occur within 2 hours of ingestion. Seek medical attention
immediately.
CAUTION: No obvious symptoms
Unfortunately, it is not obvious when a button or coin battery is stuck in a
child’s oesophagus (food pipe).
There are no specific symptoms associated with this. The child might:
- cough, gag or drool a lot;
- appear to have a stomach upset or a virus;
- be sick;
- point to their throat or stomach;
- have a pain in their abdomen, chest or throat;
- be tired or lethargic;
- be quieter or more clingy than usual or otherwise “not themselves”;
- lose their appetite or have a reduced appetite; and
- not want to eat solid food/be unable to eat solid food.
These sorts of symptoms vary or fluctuate, with the pain increasing and then
subsiding.
A specific symptom to button and coin battery ingestion is vomiting fresh
(bright red) blood. If the child does this seek immediate medical help.
The lack of clear symptoms is why it is important to be vigilant with “flat”
or spare button or coin batteries in the home and the products that contain
them.
Maintenance
