Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.
Thank´s for your help, I already recived these manual from you

Important safety requirements
This hob must be installed in accordance with the Gas Safety (Installation and Use) Regulations (Current Edition) and the IEE Wiring Regulations (Current Edition).
Location
The hob may be located in a kitchen, a kitchen/diner or bed sitting room, but not in a bathroom, shower room or garage. Before making the cut out in the worktop ensure that there is a minimum distance of 55 mm between the rear edge of the hob and the wall. A minimum distance of 100 mm must be left between the side edges of the hob and any adjacent cabinets or walls. The minimum distance combustible material can be fitted above the hob in line with the edges of the hob is 400 mm. If it is fitted below 400 mm a space of 50 mm must be allowed from the edges of the hob. The minimum distance combustible material can be fitted directly above the hob is 700 mm.
Provision for ventilation
Detailed recommendations are contained in the following British Standards Codes Of Practice: B.S. 6172/ B.S. 5440, Part 2 and B.S. 6891 Current Editions. The hob should not be installed in a bed sitting room with a volume of less than 20 m3. If it is installed in a room of volume less than 5 m3 an air vent of effective area of 110 cm2 is required. If it is installed in a room of volume between 5 m3 and 10 m3 an air vent of effective area of 50 cm2 is required, while if the volume exceeds 11 m3 no air vent is required. However, if the room has a door which opens directly to the outside no air vent is required even if the volume is between 5 m3 and 11 m3. If there are other fuel burning appliances in the same room, B.S. 5440 Part 2 Current Edition, should be consulted to determine the requisite air vent requirements.
