Yes, the cylinder housing is ventilated with a decorative pattern of holes top and bottom. Another shock the engineer gave us because he claimed we had to ventilate the housing to outside air and even GasSafe were confused about this. Luckily Calor emailed us copies of BSF482 and UKLPG Code of Practice 24 Part 1 which proved we didn't have to vent to outside the property, which is impossible with the cooker's present location) and that the vents (holes) we had were more than sufficient for the minimum required by BS5482 Part 1, 11.3.1.2, (d), i.e.:
"... Where an enclosure is to be provided for butane cylinders used inside residential premises, both vents may communicate either with the same room or internal space, or with the outside air at the same wall. The total area of the opening of the upper vent should be at least 1/100th of the floor area of the housing. The lower vent should not be less than 1/100th of the floor area of the housing when communicating direct to outside or 5/100th of the floor area of the housing when communicating with the room or compartment."
It seems there is a lot of confusion surrounding the use of Butane in the home.
