III.- INSTRUCTIONS OF USE
Once your oven has been installed and connected to the chimney, you are ready to light the
fire.
Although your oven is easy to use, the combustion process of solid fuels is complicated, as it
involves several factors and it takes time and experience to understand the process.
Before lighting your oven for the first time, please take time to become familiar with the
different control systems and parts of the unit, how to choose the wood, how to light it and
use it on a daily basis.
Primary air control:
This controls the air entering the fireplace through the grille. It is helpful when lighting the
fire. (Fig.-5)
Primary air valve (Glass Cleaning System)
It directs combustion air from the top of the door and creates a film over the glass pane that
prevents soot particles from adhering.
Draw Shut-off Valve
This valve adjusts combustion by restricting the chimney draw.
Lighting up for the first time
Before finishing the installation work in the case of an insert fireplace, it is important to check
that it is working correctly.
We recommend a slow fire for 3 to 4 hours when lighting-up for the first time. This will help
stabilise the different components and avoid any possible breakages.
In order to light up the oven, start by opening the primary combustion air valve and the glass
pane cleaning valve by moving the lever to the right.
Open the draw shut-off valve completely, too.
Once you have achieved the combustion rate you desire, adjust the valves to maintain it.
Usually, you may close the primary air valve completely and control the level of combustion
with the top primary air valve (Glass Cleaning System).
When lighting for the first times, you may notice smells due to the polimerisation of the
paint or lining covering certain parts of the unit. This is normal and will disappear after
lighting the oven 3 or 4 times.
Daily use
After lighting up for the first time, your oven will be ready for daily use.
When your oven is cold, we recommend lighting it up slowly.
The heat you wish to generate in your oven will depend on the frequency and the amount of
firewood you load.
Depending on the temperature required for cooking, regulate the rate of combustion by
adjusting the air inlet valves and the draw shut-off valve.
This will enable you to obtain the desired temperature and maintain it as long as required for
cooking purposes.
Always control oven temperature by means of the thermometer installed on the door.
