The way the BUILT-IN FIREPLACE H-03 is installed will decisively affect safety
issues and how it works.
It is important to install the fireplace correctly.
In order to ensure it has been installed correctly,
it should be installed by a professional.
A.- Assembly
In order to install the Built-in Fireplace H-03, a
chimney ("draw") must be installed using suitable metal
pipes and must extend at least 1 metre above the
highest part of the roof.
If a built-in chimney already exists, the said
chimney must be connected to the Cast Iron Fireplace
by means of a joint and perfected connected to the
smoke outlet on the device. (See Fig.-2)
It is essential to seal the joints between chimney
sections. (See Fig.-6, Pag. 9)
It is advisable to install grilles at the top of the
hood and at the bottom of the lining to allow hot air to
circulate for two main reasons:
- provide extra hot air to the room.
- avoid possible cracks in the lining.
HERGÓM provides 25x20 and 50x20 cm.
ornamental grilles as an option.
B.- Chimneys.
The way the FIREPLACE works depends on:
d) The chimney.
e) How it is used.
f) The quality of the fuel used.
Over the years, you may change the type of fuel
you use but, once the chimney has been installed in a
given place, it is not so easy to alter or reposition.
Therefore, the following information will help you
decide whether you can use your present chimney or
not or help you decide to build a new one.
This information will help you make the correct
decision.
1. - How chimneys work

Chimneys:
a) Safely evacuate smoke and gasses from the house.
b) Provide sufficient draw in the hearth to keep the fire alive.
