5.4.3.4  Installation

Take note of the following rules and requirements when 
installing a flue system:

 CAUTION! 

 Do not apply mechanical force on the parts 

during installation.

Requirements for horizontal and non-vertical piping:

•  Maximum distance between brackets of 1 m.
•  On tensile joints; maximum distance between 

brackets of 2 m.

Follow the manufacturer’s instructions.

•  Spread the brackets evenly along the piping.

Requirements for vertical piping:

•  Maximum distance between brackets of 2 m.
•  Spread the brackets evenly along the piping.

Always place a bracket on or near a bend or elbow piece, 
except if the flue pipes before and after the elbow piece 
are shorter than 0,25 m. In this case, fix the second 
element after the elbow with a bracket.

Every flue discharge system needs to be secured with at 
least one bracket. The first bracket needs to be within the 
first 0,5 m of the air heater.

When installing a flue system inside a shaft, do the 
following:

1.  Check the components for possible damage or 

blockage.

2.  Check that the pipe is at the right slope (see 

Requirements).

3.  Mark the flue pipes and fresh air pipes to avoid 

mixing them up.

4.  Make sure that the pipes extend for at least 50 mm 

when passing through a wall or other obstacle.

5.  Fix the last element before entering the shaft in 

place. If the last element is an elbow piece, the 
next element must also be fixed in place.

6.  Check if ventilation openings and inspection 

hatches comply with national and local regulations.

5

Pre-ignition

Ignition without opening the gas valve.

6

Ignition

5 seconds of ignition. The gas valve opens.

7

Flame check The air heater checks if the flame is present.

8

Burn

The heater fires up and starts to modulate.

9

Minimum

Before the flame stops, the burner will 
modulate to minimum power.

10

Burner off

The gas valve closes. The flame stops.

11

Post purge

Burner fan purges with fresh air.

System fan cools the heat exchanger.

6.2  Minimum firing time

The heater will always fire for a minimum of 4 minutes, 
even if the heat demand stops. This is to avoid a large 
amount of start and stops and to prevent condensate from 
accumulating in the flue system.

 NOTICE 

 The heater will try to ignite 2 times before it stops 

and gives an error.
