RE: Re: What's the REAL story with LD11's and heat?

Never really gave that much thought Keith not did I expect those units
to produce enough heat to be a fire risk! My cure was to leave a fair
bit of space in the unit and drill vents in the side, as well as the
gaps between the modules to run the wiring the top terminals, thought
that would suffice.
