7. Installation guidelines

Prior to erection, it has to be ensured that the local supply conditions (type of gas and pressure) and
the present setting of the device match each other and that the local electric supply conditions
correspond to the electric data on the rating plate.
Installation regulations
During the setup of mobile WLEs with closed combustion chamber all local building, fire protection and
safety regulations have to be observed as a matter of principle.
Installation site
The devices must not be operated in locations, in which ignitable gas-air or dust-air mixtures may
occur (such as at filling stations, paint shops, et cetera).
Floors and ceilings have to be fire-retardant. The suction and exhaust vents must not be constricted.
Installation rooms
1. Setup of the WLE in closed, well-ventilated rooms with connection to a chimney:
- The minimum room size has to correspond to an average heat requirement of the installation
room of 0.058kW/cum.
- The required fresh air feed to ensure perfect combustion must be ensured by all means
(windows, doors or other openings).
