WA 33 UNIVERSAL OIL HEATER OPERATING MANUAL aryjnąależy dokładn 1.
In order to ensure proper use and fault-free operation of the furnace, read this manual carefully. 1. Destination The WA 33 universal oil heater is intended for heating the industrial rooms which are not included in the central heating system (workshops, car maintenance services, industrial halls, warehouses, inventory buildings, basements, garages, etc.
The second bimetallic sensor is placed nearby the air supply fan, its threshold temperature is 90°C. Opening of its contacts, in consequence of exceeding the threshold temperature, causes immediate switching of the furnace into the Overheating mode (see section 8 of this manual). The heater is equipped with a balance sensor placed below the overflow tank (the so called, overflow fuse). Filling this tank causes immediate switching of the furnace into the Overflow mode (see section 8 of this manual).

Installation of the device - during the installation of the device, meet all the local regulations, including the regulations referring to the national and European standards place the furnace on a flat concrete ground level the device.
- - if possible, all the chimney section should be vertical – avoid horizontal sections as well as bends of the chimney pipe, if necessary (e.g.

operates until the furnace temperature is below 35°C (damping). After the temperature reaches less than 35°C, the furnace returns to the Stop phase. The furnace may be switched off automatically in the following cases: - overheating of the combustion chamber - overflow The overheating signal is generated by the bimetallic sensor placed nearby the fan. The opening of the contacts is signalled by the exceeding the threshold temperature value.

Do not connect the device to the mains, when the fan is in operation, wait until the furnace is cooled off. The furnace is switched off automatically. Remember that after the device is switched off, the cast-iron pan still maintains the higher temperature for some time (depending on the ambient temperature) and it is not allowed to switch on the furnace until it is cooled off Fig.6.

Maintenance The heater requires little maintenance activities. The observance of manufacturer’s recommendations will ensure fault-free and safe operation of the device.
10. Repair of defects In the case of the failure of the device, the list below may help in locating the defect. In general, its removal is simple. The most frequent problems are listed below. The digits signify the possible causes The order of the digits expresses the probability of occurrence of the defect. NOTE: Before starting any activities, pull the plug out of the mains socket.
