Frequently Asked Questions - CHT20X DIMPLEX

How to install the Dimplex CHT20X fireplace?

The fireplace can be placed on a level surface or mounted flush to a wall. For wall mounting, drill 6mm holes as per Fig.1, insert plugs and screws leaving 10mm gap, then lower the appliance onto the screws via keyhole slots. For freestanding, use adjustable feet to level and secure with anti-tip screws if needed.

How to operate the remote control?

Open the remote by removing the screw at the back, slide off the cover, insert the included CR2025 battery, then replace cover and screw. Point at the fireplace and press buttons for functions like power, flame, heat, timer, and temperature.

How to clean the glass screen?

Always unplug and cool the fireplace. Use a chamois leather to carefully clean the glass. Do not use proprietary cleaners or abrasive products.

What to do if the heater does not turn on?

Check that the appliance is plugged into a working socket and the mains switch is on. Ensure the thermal cut-out has not tripped (if so, unplug, wait 10 minutes, remove any obstructions, then reconnect). Also check the remote battery if using remote.

WARNING: KEEP BATTERIES OUT OF REACH OF CHILDREN

1. Swallowing may lead to serious injury in as little as 2 hours or death, due to chemical burns and potential perforation of the oesophagus.
2. If you think batteries might have been swallowed or placed inside any part of the body seek immediate medical attention
3. 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.
4. Dispose of used button batteries immediately and safely. Flat batteries can still be dangerous.

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.

Installation Instructions

This heater must be used on an AC \~ supply only and the voltage marked on the appliance 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

Your electric fire is designed to be used in front of a fireplace opening or placed against a wall anywhere in the room.

When installing this appliance in front of an existing fireplace opening, we recommend that an open chimney or flue is blocked off. We recommend that non-flammable materials are used to 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.

At the rear of the appliance, two adjustable feet are provided for levelling the appliance where the fire is being installed on an uneven surface. You can adjust the foot by removing the two screws and refitting the foot in the required position.

The appliance is supplied with screws and rawl plugs to provide extra stability to prevent it from accidentally being knocked over. The rawl plug supplied is suitable for use in block walls (other wall types may need alternative rawl plugs).

To place the appliance flush to a wall please follow these instructions:

1. Drill holes using a 6mm drill as illustrated in Fig. 1.
2. Insert plugs and screws. Do not fully tighten screws, leave the head of the screw at least 10mm away from the wall.
3. Place the keyhole slots on the appliance over the screws and lower into position.
   If the unit is not to be place flush to the wall, the screws can be left protuding further than 10mm and longer screws can be used as required.

Fuelbed Assembly

Models are supplied with a range of fuelbed media, which you can arrange to your preference. (Cheriton Deluxe is supplied with coal only).

Loose coals, crystals, pebbles and logs are packed separately within the carton. When the appliance is installed, place the fuelbed material on the fuelbed and arrange to your liking. We recommend the following step, in order to achieve the optimal effect.

1. Place crystals on fuelbed, covering the top surface of the fuelbed. These will provide a glowing embers effect, when the flame effect is operating. See Fig.2 below.
