1 Introduction
1.1 General
This user manual is intended for both the installer and the end user of the Kabola COMPACT 7 heating
boiler. There is a wide range of COMPACT 7 heating boilers with a broad range of applications. With
this purchase you obtain a product of the highest quality due to the practical application of the latest
European standards and directives and modern technologies. Kabola Heating Systems BV has been
developing and producing heating systems in the Netherlands since 1947.
Use the manual for both installation and while maintaining and replenishing your heating system. Save
the manual carefully for future use. You can obtain a digital copy at any time by mailing [email protected]
or by downloading from the website www.kabola.nl.
1.2 Area of application
The COMPACT 7 central heating boiler is intended to supply heat to heat water (or coolant) in a central
heating system and/or in combination with the Kabola hot air system.
The COMPACT 7 BOILER with boiler control is intended to heat both the heating system and hot
water using a boiler vessel.
The COMPACT 7 COMBI boiler is intended to heat the heating system and hot tap water without a
boiler vessel.
The boilers are not intended to directly heat the space in which they are installed. Heating only takes
place using radiators, a hot air system, underfloor heating and/or any custom-made airco systems in
which the Kabola COMPACT 7 is integrated. When using the boilers account must be taken of the
dimensions of the spaces to be heated.
So always carry out a capacity calculation beforehand or take advice.
1.3 Description of the boilers
The COMPACT 7 boiler heats the boiler water by means of an oil burner assembled on the boiler. The
boilers are supplied as standard as a 230 V design (also see the technical specifications in annex A).
Domestic fuel oil 1, domestic fuel oil 2, diesel or gas oil must be used as fuel. Should you want to use
biofuels or mixtures ask for additional advice. These fuels are being developed at speed and have
advantages and disadvantages with which account must be taken.
1.4 Technical specifications
You can find the most important specifications on the type plate attached to the right-hand side of the
boiler. The address of the manufacturer is also mentioned here. You can find the full technical
specifications on pages 20-22.
1.5 Guarantee provisions
We refer you to the guarantee certificate for the guarantee provisions.
It is very important that the boiler is brought into use after installation, and that stipulated in
the protocol for bringing into use is returned to Kabola Heating Systems BV in Vianen. You are
then covered by the guarantee.

4 Installation and bringing into use
In this section you can find instruction and tips for the correct placing and connection of the boiler and
the associated equipment.
Warning: Do not place any flammable and/or gaseous substances that may cause
danger of explosion or fire in the space where the boiler is or is to be
installed.
4.1 Installation
4.1.1 Placing the boiler
 Place the boiler in a moisture-free space.
 Place the boiler on a strong, horizontal surface and fasten it firmly with the angle brackets and
M5 bolts supplied.
 Ensure sufficient ventilation in the space where the boiler is to be installed.
 As a general rule for determining the diameter of the ventilation opening you can use 2.5 times
the diameter of the flue gas outlet (at least 150 mm).
 Secure the base of the boiler against slipping using an angle bracket with bolts or tack-
welding.
 Make sure there is a distance between the outlet and the wall of at least 10-20 mm because of
the heat transfer from the flue gas outlet.
 Ensure sufficient space around the boiler for service and maintenance work.
 Provide an earthed wall socket (230 V AC) for the connection of the boiler.
4.1.2 Connection to the central heating system
PIPING
When assembling the piping the following points must be respected:
 Assemble the piping in such a way that the boiler and control panel remain accessible;
 Ensure sufficient ventilation in places where air can accumulate.
Note: Ensure ventilation if the piping does not slope upwards.
EXPANSION TANK
An expansion tank must always be assembled with a closed central heating system (pressure system).
 Always assemble the expansion tank in the return pipe (see fig 2) as near as possible to the boiler.
 The size of the expansion tank is approximately 10% of the total water capacity of the whole
system. For example; with a volume of 120 litres, assemble a 12-litre expansion tank.

4.1.3 Flue gas extraction
GENERAL
Flue gas extraction is an essential part of your heating installation. Well-assembled flue gas extraction
considerably extends the working life of your heating boiler and has a positive effect on heating
efficiency.
Warning: Because in most cases the flue gas temperature is higher than 180 °C, it is the desirable to
insulate the outlet with heat-resistant material in places where contact with
body parts is possible. These are available from Kabola Heating Systems B.V.
 Ensure the correct length/diameter proportions. We advise assembling a flue gas outlet with a
diameter of 50 mm and a maximum length of 3 metres.
 On sailing and seagoing vessels we advise using a vertical flue gas discharge system (see fig 5).
AUTOMOTIVE APPLICATION
With the installation of the heating system for an application not for use on water, one can decide to
keep the flue gas outlet as short as possible.
HORIZONTAL OUTLET WITH SKIN FITTING
It is possible to bring the flue gas outlet horizontally from the boiler through the wall. The following
points must then be respected:
 The maximum permitted length without bends is 3 metres.
 Make sure that the outlet is amply above the water level. If this is not possible use a curved
construction (a swan neck as pictured on the right in figure 4).
 Use a skin fitting (single- or double-walled) to bring the flue gas outlet through the wall.
 Use as few as possible bends, no more than 3 bends of 90 °.
Tip: If with the existing assembled flue gas outlet you have a larger diameter than
the diameter of the flue gas outlet from the boiler, we recommend assembling
a flexible flue gas outlet (50 mm diameter) in the existing flue gas outlet. The
necessary adaptors and auxiliary parts are available from Kabola Heating
Systems B.V.
Warning: When using a flue gas outlet longer than prescribed it is possible that
condensation water may originate in the outlet. It is very important that the
condensation water does not form a water trap with the flue duct
becoming blocked (as pictured on the left in figure 4).
Using a swan neck (as pictured right in figure 4) prevents water from
entering the flue duct from outside.
Figure 4

10
VERTICAL OUTLET
This discharge method is the preferred choice for seagoing
vessels and yachts. This is because these vessels can be at
large inclinations caused by waves and can list. For this
discharge method the following points are important:
 Fit a rain-proof cowl on the end of the pipe (see fig 5).
 Use deck holes to bring the flue duct through the deck and
the ceiling.
 Keep the flue gas outlet as vertical as possible.
 Use no more than 3 bends of 90 °.
 Fit a drain piece.
 The maximum permitted length with a vertical system is 5
meters.
 With a vertical outlet always use a drain!
Figure 5
Tip: Kabola can manufacture a deck hole at an angle so the flue is straight as custom work.
FLUE GAS MATERIALS
Kabola can supply all flue gas materials to simplify installation such as:
 Stainless steel cowls;
 Flexible stainless steel flue gas hose;
 Stainless steel discharge pipes (from diameter 70 mm);
 Stainless steel deck holes for ceiling and deck;
 Stainless steel flue gas dampers;
 Drain pieces;
 Hose clips;
 Stainless steel adaptors;
 Skin fittings;
 Insulation sleeves (per meter)
Always install a drain with tap directly on the boiler
(See Figure 5.a)
Figure 5.a

4.1.4 Electrical connection
Warning: Make sure there is no voltage on the system
when you start connecting. Only use multi-core
cables with flexible core (minimum 0.75 mm2). The
available voltage must of the same quality as
normal shoreside power.
Tip: If you use a transformer we advise using a 900W
sine wave transformer.
Do not place the room thermostat near a heat
source.
