7.2.3 Placing the appliance control unit under the platform
If, in case of a situation with a platform, there is no room for the control hatch, the appliance control unit must be placed
directly under the platform using the 'electricity protective cabinet'.
3- It is not permitted to mount the appliance control unit to the appliance.
- Disassemble the appliance control unit from the transport bracket.
- Remove the transport bracket and dispose of it as required.
3- There is 230V of mains voltage on the appliance control unit.
- Avoid kinks in the pipes.
- The electricity protective cabinet and the appliance control unit should always be placed indoors on a dry location.
When placing the appliance control unit under the platform using the protective cabinet, proceed as follows (see fig 7-7).
1Mount the attachment bracket of the protective cabinet both against the back wall and bottom side of the platform,
using suitable fastening materials (Step 1).
1Disassemble the appliance control unit from the appliance and attach it to the fastening bracket of the protective cabinet
(Step 2).
1Connect the gas pipe as described in section 6.3 (Step 3).
1Position the gas pipe, flexible gas pipe and cables on the recesses in the fastening bracket of the protective cabinet
intended for that purpose and fasten them with tie-wraps (Step 4).
3- Ensure the cables of the ionization and ignition pins are lying free from metal parts as much as possible and are lying
fully free from signal and voltage cables.
- In case of damage to the mains cord, it should be removed immediately and replaced by a cord of the same type.
1Place the data plate of the appliance in the bracket of the protective hood (Step 5).
1Hook the protective hood into the fastening bracket and fasten it with the self-tapping screw (Step 6).

7.2.4 Back wall connecting to the glass of the side pane
(see fig. 7-8 and 7-9)
When installing the wall up to the side pane, proceed as follows:
1Make sure the back wall to be placed has the correct dimensions (see fig. 7-8).
1Loosen the self-tapping screws of the vertical decorative strip by a few turns and adjust the profiles to the correct
distance. The distance depends on the thickness of the wall. For material thickness 20 mm and 30 mm, indicators have
been applied. The cover plate is no longer required and can be removed. Re-tighten the self-tapping screws (see fig. 7-9).
1Maintain a 5 mm distance between the wall and the side pane.
3- In case of a 2-sided appliance, construction on the glass of the side pane is only possible at the back wall side, not at
the side wall side. It has to be possible to remove the front glass pane. For this purpose, it should be possible to remove
the decorative strip.
- In case of materials up to the glass, it is important to maintain a 5 mm minimum distance from the glass!
- In case of materials up to the glass, heat-resistant material should be used that is at least able to resist a temperature of
85°C.
