General information

1.3 Description

The principle parts of the design consist of measure made steel/stainless

steel plates. The boiler has been pressure- and tightness tested and is

provided with skin-tight heat insulation as well as powder coated covers

plates.

Flue gas outlet

Connections on the top and rear side.

Burner hood

The burner hood is an

integrated and sophisticated

component part of the boiler.

Hinged arm

The cleaning door is equipped with hinges

which serves as a hinged arm. In that

way is it easier to swing out the

burner in connection to inspections and

maintenance.

Operator unit

The operator unit of the Comfort-control –

Siemens AVS37.294. For more information,

see the part Electrical installation –

Comfort-control.

Power pack

The power pack of the control panel –

Siemens AVS16.290. For more information,

see the part Electrical installation –

Comfort-control.

Turbulators

The function of the turbulators is to

create turbulence of the ﬂue gases, in

order to improve the amount of thermal

energy which is transmitted to the

boiler water. All sizes are from factory,

equipped with for each size adapted

standard turbulators. The turbulators

are reached behind the cleaning door

in the front of the boiler.

Adjustable feet

The boiler is equipped with four

adjustable feet.

Basic unit

The basic unit of the Comfort-control

– Siemens RVS43.143. For more

information, see the part Electrical

installation – Comfort-control.

Heat insulation

In order to minimize the heat losses the

boiler is provided with solid, skin-tight

heat insulation.

Ripples

The boiler-sizes 33, 40 and 63 kW

are equipped with ripples. The ripples

enlarge the the surfaces in which the

interchange of heat of the second ﬂue

gas stroke takes place. This results in

an optimized heat transfer of the ﬂue

gases to the boiler water.

Combustion chamber

The generous sized combustion

chamber offers the adjusted Low NOx oil

burner optimal performance.

DUO-Temperature System

The combustion chamber is surrounded

by two mantles, which allows low-

temperature operation protected from

dew-point corrosion resulting in a long-

life operation.

Cleaning door

Thanks to the large cleaning door are the

turbulators within easy reach as well as it

facilitates the simultaneously cleaning and

maintenance of the heating surfaces of the

boiler.

General information

!Check the pressure in

the expansion vessel

annually.

2. Installation

2.1 General information

The installation must be carried out by authorized personnel according to

existing engineering standards and building regulations.

The boiler must be connected to an expansion vessel in an open (the

expansion vessel of high placement together with safety- and return pipe)

or a closed system. At an open system the distance between the expansion

vessel and the highest placed radiator must not be less than 2,5 m to avoid

oxygen-enrichment of the system.

2.2 Boiler room

The boiler room must correspond to existing building regulations and

particularly then the ﬁring regulations of the present country.

The boiler room must be equipped with a venthole for air supply. The cross

section area of the venthole must be at least 6,5 cm2pro 1 kW boiler output.

2.3 Transport

To avoid transport damage, do not unpack the boiler until it has been

transported to its site in the boiler room. The boiler can be handled and lifted

in the following way:

• Forklift

• Lift band round the pallet. Note! Only with the packing on.

• Sack barrow

• By putting carrier pipes in the water connections on the rear side,

respectively the build-in 1” carrier sockets on the front side of the boiler
