Whilst I sit here in a huge cloud of smoke it strikes me that, whilst DRI are making improvements and refurbishing units (especially those at Pine Lake), perhaps when you fit an extractor above a hob - should it not actually be ducted out of the building?
Ours appears to simply circulate the smoke and steam out of the pans!
If you dont spend approx £20 per unit on this ducting, you might as well remove the smoke detectors...
I expect I will be getting a visit shortly from someone on site, though there are no audible alarms inside the unit...
Whilst waiting I shall enjoy my steak.
This posting is made "tongue in cheek", and is merely a suggestion not a criticsm.
I should add that we are not in a refurbished unit.
