Fuel and heating power

The fuelling has been optimised from a

technical point of view, both with regard to the

conception of the hearth and the respective

air power supply, and with regard to the

emissions.

We invite you to support our commitment in

favour of a clean environment by observing

the following indications with regard to the

use of fuelling materials which do not contain,

nor produce, noxious substances.

Only use natural and seasoned wood, or

wood briquettes, as fuel. Damp wood, freshly

cut or stored incorrectly has a high water

content and therefore does not burn well,

produces smoke but very little heat.

Only use burning wood with minimum two

years seasoning in an airy and dry room. In

such case, the water content will result lower

than 20% of the weight. In this way you will

save in fuelling material, as the seasoned

wood has a higher heating power.

Never use liquid fuel such as petrol, alcohol

or similar. Do not burn waste.

Radiation ﬁ eld

Do not place any fuel object inside the

radiation field of the glass hatch.

Initial start-up

The paint of the hearth is subject to the so

called ageing until the working temperature is

reached for the first time.

This may cause unpleasant odours. In such

case, adequately air the room where the

hearth is installed. The phenomenon will

disappear after the first ignitions.

Danger of burns

The external surfaces of the CRISTAL hearth,

in particular the glassceramic panel, heat up.

Do not touch - danger of burns! Children

should be particularly warned. However,

children must be kept away from the switched

on hearth.

Air grills

Careful not to close or obstruct the hot air

outlets. This causes danger of overheating

inside the covering.

Hearth functioning with hatch open

In case of functioning with hatch open, the

hearth will have to be constantly kept under

control. Very hot coal may be projected

outside the hearth.

Addition of fuel

The use of a protective glove is suggested to

“add wood”, in that, in case of prolonged

use, the handle may heat up.

Slowly open the hatch. In this way, the forming

of a vortex of leaking smoke is avoided.

When is it time to add wood? When the fuel

has almost turned to coal.

Functioning in mid-seasons

To suck the air for fuelling and to discharge

smoke, the CRISTAL hearth requires draught

from the chimney/flue. With the increase

of the external temperatures, the draught

decreases. Verify the chimney draught before

lighting the fire, in case external temperatures

are higher than 10°C.

If the draught is weak, initially ignite a

“starting” fire using small sized igniting

material. Once the correct chimney draught

is restored, you can introduce the fuel.

Air ﬂ ow in the room where the hearth

is installed

The CRISTAL hearth is able to work regularly

only if in the room where it is installed there

is sufficient air flow for the fuelling. Provide a

sufficient air flow before igniting the chimney.

The air power supply devices for fuelling must

not be altered.

Whenever the air volume results scarce and

the type of building in which the chimney

is installed particularly air sealed, it will be

necessary to install a supplementary air inlet

of 150 cm

as previously said.

Igniting with cold hearth

Check that the ash bed is not too high.

Maximum height: 5 cm underneath the hatch

edge. If the ash bed becomes too high, there

is a danger that when opening the hatch to

add wood, fragments of coal may fall out of

the hearth.

2. Pull the regulating lever of the air valve in

the “switch on” position. Air for fuelling will

flow intensely to the wood in the hearth, to

rapidly reach good fuelling.

3. The wood must be placed in the hearth

without excessively crowding it. Place an

igniter between the wood logs, and ignite. The

igniters are practical aids to start the fuelling.

Attention: very large wood logs do not ignite

properly in a cold hearth and free noxious

gasses. Never use material such as petrol,

alcohol and similar to ignite the hearth!

At this point, close the hearths hatch and

supervise for a few minutes. Should the fire go

out, slowly open the hatch, allocate another

igniter between the wood logs and re-ignite.

Should the fire not require further addition of

wood, the moment the same fire is exhausted,

push the regulating lever of the air valve in the

“maintain fire” position. Do not carry out such

regulation during the fuelling phase, in that,

when the lever is in the maintain fire position,

the air flow for fuelling results completely

blocked. In case of sudden oxygen flow (for

ex. due to the opening of the hearths panel)

the “gasses still present” in the hearth and

in the eventual heat recovery surfaces, may

react violently with said atmospheric incoming

oxygen.

Power supply with hot hearth

With the glove provided, slowly lift the hatch

and add the desired amount of wood in the

hearth, placing it on the existing coal. In this

way, the wood will heat up with the consequent

expulsion, in the form of steam, of the

contained humidity. This leads to a decrease

of the temperature inside the hearth. The

volatile substances let out at this point by the

fuelling material, require a sufficient air flow,

so that this critical phase, from a technical

point of view of the emissions, can be rapidly

carried out and the required temperature can

be reached for correct fuelling.

A further suggestion:

For the initial ignition of the hearth, always

use the smaller wood logs. These rapidly

burn and therefore bring the hearth to the

right temperature in less time. Use the larger

wood logs to re-power the hearth.

Certain types of wood briquettes inflate once

they are in the hearth, meaning they stretch

under the heat and increase in volume.

Always place the wood well inside the hearth,

nearly touching the rear wall of the same,

so that should it slide, it does not fall in the

hatch.

Removing the ash

You can remove the ash using a shovel or

with an ash sucker. Only place the ash in non

fuelling containers, bearing in mind that the

residual coal may re-ignite even after more

than 24 hours from last fuelling.

USE INSTRUCTIONS

N.B. The seasoned wood has a heating power of about 4 kWh/kg, whereas fresh wood has a heating power

of only 2 kWh/kg. Therefore, to obtain the same heating power, double the fuel is required.

ATTENTION: If the hearth is powered with an excessive amount of fuel or with inadequate fuel, the risk

of over-heating may be incurred.
