I.- INTRODUCTION
The HV-2007 Fireplace is supplied in a single version, with a convection
chamber and cast-iron fireplace.
SPECIFICATIONS:
• Made from sheet steel and painted in black.
• Cast-iron fireplace which favours heat transmission.
• Screen: retractable by vertical sliding with a front hinged door.
• Natural convection chamber providing better performance.
• The two convection air inlets are provided for the addition of a forced
ventilation system.
• The four air outlets allow tubes to be connected in order to direct the natural
convection of hot air to the room in which the HV-2007 is installed through the
hood of the fireplace or by means of the fan which is provided as an accessory,
in other adjoining rooms.

II.- INSTALLATION
How the FIREPLACE is installed will be integral to its safety and good working
order.
It is very important that the fireplace is properly installed.
A safe installation of the FIREPLACE and the chimney can be difficult and it is
advisable to entrust the work to a professional. If you decide to do it yourself and
have any queries, consult an expert or call us directly at the factory.
To prevent the hood panels from overheating, you are advised to coat the inside of
the panels with an insulating material such as rock wool.
2.1.- CHIMNEYS
The performance of the FIREPLACE depends on:
The chimney.
The way it is operated.
The quality of the fuel used.
Over the years you will be able to change the type of fuel, but once installed the
chimney it is not easy to move. The following information will help you to decide
whether you can use the existing chimney or if you have to build a new one.
The base where you are going to place the Fireplace must have a flat surface without
any unevenness which will prevent it from fully insulating. The supporting base must
be made from heat-resistant materials.
2.1.1. How chimneys work
A basic understanding of how chimneys work will help you to get the most out of your
FIREPLACE. Their main functions are:
To vent the smoke and gases from the house without danger.
To draw enough air to the fireplace in order to keep the fire alive.
What is draught?
Hot air’s tendency to rise creates a draught.
When the FIREPLACE is lit the hot air goes up the chimney and into the outside
atmosphere. The chimney flue heats up and maintains the draught. The draught
works properly only once the chimney has heated up.
The position, size and height of the chimney affect the draught.
The following should be considered:
Chimneys located inside the house stay hot, so the draught is stronger.
The recommended size for the chimney maintains a good draught.
The height of the chimney affects the draught; the higher the better the draught.
The chimney must protrude by at least one metre over the highest part of the roof.
There are other factors which affect the draught:
Trees and/or high buildings near the house.
The wind speed. Generally continuous strong winds increase the draught, but stormy
winds can reduce it.
Outside temperature. The colder the outside air, the better the draught.
Barometric pressure. On rainy, humid or stormy days the draught is usually weak .

17
Liveliness of the fire. The hotter the fire, the stronger the draught.
Cracks in the chimney, a badly sealed or dirty door, entry of air at tube joints,
another device connected to the chimney etc. can cause inadequate draughts.
2.1.2. Formation of creosote and cleaning.
When wood is burned slowly, tars and other organic vapours can accumulate in the
flue which when combined with the atmospheric humidity form the creosote. The
creosote vapours can condensate if the walls of the chimney are cold. If it ignites the
creosote can cause extremely intense fires. Any accumulation of creosote must be
eliminated. Given that the accumulation of creosote depends on so many variables, it
is very difficult to predict when the chimney must be cleaned. Visual inspections are
the safest way to be certain that the fireplace is free of creosote and we therefore
recommend installing it in such a way that makes it easy to access.
2.1.3. Options.
If you are going to build a chimney for the FIREPLACE, you have two options:
A brickwork chimney.
A metal chimney.
The studies show that there is little difference between metal and brickwork in terms
of draught performance. You can choose the one that most suits your home.
Whenever possible, position the chimney inside the house; this will provide a better
draught, accumulate less creosote and the chimney will last longer.
THE ADVANTAGES OF BRICKWORK CHIMNEYS ARE:
The bricks and tiles reduce the cooling of the smoke in the chimney.
The brickwork’s ability to store heat keeps the home warmer for longer after the fire
has gone out.
It can be built to the individual’s taste.
If it is well built it can be more fire resistant than the metal chimneys.
Brickwork chimneys must be well lined in order to prevent the smoke from cooling.
They must be built from materials that withstand high temperatures and corrosion.
They can be round, square etc; the important thing is their inner cross section.
For brickwork chimneys the measurements described in the 9. TECHNICAL
INFORMATION section must be used.
THE ADVANTAGES OF METAL CHIMNEYS ARE:
Easy to install.
Allows slight changes in the direction of the chimney which provides more flexibility
when choosing where to install the FIREPLACE.
Thanks to its curved elbows the sharp angles which restrict draught are eliminated.

18
2.1.4. Some rules.
Below are some rules to follow when building the chimney.
Use resistant and incombustible materials. Do not use fibre cement.
Choose a route which is as vertical and straight as possible and do not connect
several appliances to the same chimney.
Ensure that the flue does not come out into an area near buildings; it must exceed the
nearest building top if there is an adjoining structure.
Choose a place for the flue which is as protected from the cold as possible.If possible
position the chimney inside the house.
The internal walls must be completely smooth and free of obstacles. At the joints
between tubes and built-in chimneys, avoid choking.

19
It is very important for the joints between tubes to be well sealed in order to close off
potential cracks that would allow air to enter.
To ensure the chimney is airtight proceed as follows:
- Cover the outlet on the roof.
- Place paper and damp straw in the lower part of the chimney and ignite.
- Observe the potential cracks where the smoke comes out and seal them.
It is very important for the chimney to protrude by at least one metre over the highest
part of the roof. If you need to increase the draught the height of the chimney will
have to be raised.
Ensure chimney caps do not hinder the draught.

20
Clean the chimney at least once a year.
The most effective cleaning method for the chimney ducts is using appropriate
chimney brushes. There are chemical products which help to postpone the need for
cleaning with brushes.
The brushes must be as close as possible in size to the diameter of the chimney.
The joints between the tubes making up the chimney, in the event of being simple
metal tubes, must be sealed with fireproof filler.
The female part of the tubes must always point upwards in order to prevent the
creosote that forms from being emitted.
Outdoor metal chimneys must be built with double thermal insulated tubes
designed specifically for solid fuel.
5.1.5. Assembly with existing chimneys.
When existing chimneys are being used, it is advisable to place one or two metres
of metal tubing inside the chimney, ensuring that the opening between the built-in
chimney and the tubes is sealed.

V.- PRESERVATION PRODUCTS
INDUSTRIAS Hergóm, S.A. places at your disposal a number of products for
preserving your fireplace:
-Anti-soot: a powerful catalyst which favours the elimination of
unburned waste.
-Firelighter cubes: an essential product for lighting the fire quickly and
cleanly.
-Glass cleaner: the ideal treatment for eliminating charred fat from the
glass on stoves, chimneys etc.
VI.- CLEANING AND MAINTENANCE
6.1.- PAINTED CAST-IRON PARTS
Must be treated when the FIREPLACE is cold using a cloth soaked in a little clean
olive oil (the type used for cooking). Clean with a dry cloth.
6.2.- FIREPLACE GLASS
The panes of glass on stoves are fairly effective products. Never try to clean the glass
when the stove is in operation. We recommend using the Hergóm window cleaner.
REPLACEMENT: your fireplace’s glass is Thermoshock, manufactured specifically
for wood and/or coal burning fireplaces. If the glass breaks it must be replaced with
glass of the same specifications. Contact our distributor to obtain the right glass
accompanied by assembly and joint instructions.
VII.- OPERATING INSTRUCTIONS
Recommendations: The first time the fire is lit it must be kept on low heat for 3 to 4
hours in order to stabilise the various parts that make up the fireplace and thereby
prevent potential faults.
Before cladding the fireplace with bricks or any other fireproof material it is
advisable to ensure that it works properly.
Draught regulation: In order to regulate the heat, turn the chimney’s wing-nut valve
and move the grill in order to regulate the intake of primary air.

23
VIII.- SAFETY
There are certain risks which must be taken into account when starting to use your
solid fuel burning FIREPLACE, whatever the model. These risks can be minimised by
following the instructions and recommendations provided in this manual.
Below we provide a number of rules and recommendations, but above all we advise
you to use common sense:
1. Keep anything combustible (furniture, curtains, clothes etc.) at a minimum safety
distance of 0.90 m.
2. Do not heat the FIREPLACE excessively and for a long period of time.
3. The ash must be emptied into a metal container and removed from the house
immediately.
4. You must never use combustible fluids to light your fireplace. Keep any kind of
flammable liquid away from the fireplace (petrol, paraffin, alcohol etc.)
5. Inspect the chimney periodically and clean whenever necessary.
6. Do not position the fireplace near combustible walls.
FORCED CONVECTION.
If you install a fan to force the convection, position the air inlet on the outside of the
built-in cladding, preferably in an adjoining room or corridor.
For safety reasons:
The fan must always be installed so that it blows air towards the FIREPLACE
convection chamber and must never be sucking from the chamber. This will prevent
a depression which could suck smoke from chimney or the FIREPLACE itself.
If the power supply cable is damaged it must be replaced by the manufacturer or by a
technical support service or qualified personnel in order to avoid any danger.
INDUSTRIAS HERGÓM, S.A. is not responsible for the damages caused by
