2 Safety
2 Safety
2.1 Designated application
The combustion manager W-FM 25 is suitable for use with:
oil burners
▪
gas burners
▪
dual fuel burners.
▪
Improper use could:
endanger the health and safety of the user or third parties,
▪
cause damage to the appliance or other material assets.
▪
2.2 When gas can be smelled
Avoid open flames and spark generation, for example:
do not operate light switches,
▪
do not operate electronic equipment,
▪
do not use mobile telephones.
▪
Open doors and windows.
▶
Close gas isolating valve.
▶
Warn the inhabitants (do not ring door bells).
▶
Leave the building.
▶
Inform the heating company or gas supplier from outside of the building.
▶
2.3 Safety measures
Safety relevant fault conditions must be eliminated immediately.
2.3.1 Normal operation
All labels on the unit must be kept in a legible condition,
▪
the unit should only be operated with its cover in the closed position,
▪
do not touch moving parts during operation,
▪
stipulated settings, service and inspection work should be carried out at regular
▪
intervals.
2.3.2 Electrical connection
For work carried out on live parts:
Observe the accident prevention instructions BGV A3 and adhere to local direc-
▪
tives,
tools in accordance with EN 60900 should be used.

2 Safety
2.3.3 Gas supply
Only the gas supplier or an approved agent may carry out installation, alteration
▪
and maintenance work on gas appliances in buildings and properties.
Pipe work must be subject to a combined load and valve proving test and usability
▪
testing relative to the pressure range intended (e.g.
DVGW-TRGI, work sheet G 600).
Inform the gas supplier about the type and size of plant prior to installation.
▪
Local regulations and guidelines must be observed during installation (e. g.
▪
DVGW-TRGI, work sheet G 600; TRF Band 1 and Band 2).
The gas supply pipe work should be suitable for the type and quality of gas and
▪
should be designed in such a way that it is not possible for liquids to form (e. g. condensate). Observe vaporisation pressure and vaporisation temperature of liquid
petroleum gas.
Use only tested and approved sealing materials, whilst observing all process in-
▪
formation.
Re-commission the appliance when changing to a different type of gas.
▪
Carry out soundness test after each service and fault rectification.
▪
2.4 Alterations to the construction of the equipment
All conversions require written approval from Max Weishaupt GmbH.
No additional components may be fitted, which have not been tested for use with
▪
the equipment,
use only original Weishaupt replacement parts.
▪
2.5 Noise emission
The noise emissions are determined by the acoustic behaviour of all components fitted
to the combustion system.
Prolonged exposure to high noise levels can lead to loss of hearing. Provide operating
personnel with protective equipment.
Noise emissions can further be reduced with a sound attenuator.
2.6 Disposal
Dispose of all materials used in a safe and environmentally friendly way. Observe local
regulations.

4.3 Linearisation
During commissioning it is possible to carry out linearisation of the operating points
for gas burners or for gas operation.
During linearisation a straight line is generated from the operating point displayed to
P9. The values on the straight are adopted as the new operating points.
Initiate a calculation after P9:
Press [ENTER] key.
▶
Combustion manager changes to linearisation mode.
✓
The linearisation mode can be interrupted using the [-] key.

Risk of electric shock
Working on the unit when voltage is applied can lead to electric shock.
Isolate the unit from the power supply prior to starting any work.
▶
Safeguard against accidental re-start.
▶
The conversion must only be carried out by qualified electricians. Observe local regulations.
Removing W-FM 20 … 24

Fitting W-FM 25
On sizes W30 and W40, the burner motor should be fed via contactor (except when
using variable speed drive).
If the boiler control is protected by an internal 10 A fuse, the plug cable for separate
motor power supply can be used. This means it is not necessary to install a separate
voltage supply for the motor.
Pre-fusing of separate supply line:
min 10 AT
▪
max 16 AT
▪
Observe inputs and outputs of combustion manager W-FM 25 (see Ch. 3.1).
▶
If required, remove contactor and snap it on to the carrier rail 1 of the bracket
▶
supplied.
If required, fit bracket 2 supplied.
▶
Fit combustion manager.
▶
Plug in all plugs, if necessary use extension cable No. 4.
▶
On gas and dual fuel burners, plug in bridging plug No. 15 supplied
▶
(see Ch. 3.1).
If necessary, connect supply line for burner motor or plug cable for motor voltage
▶
supply to the connection plug of the contactor.
