total output canon gas miser,Windsor 1978?

The cannon miser had several versions, so its impossible to give you an accurate output unless you give the exact model, I'd guess about 5 or 6 Kw not 1.5.
However, the radiants will definately be obsolete.
Now, why don't you go and buy a new fire for Christ's sake?
Its 32 yrs old!!
Get a grip, get a new fire and use some common sense!!
Kind Regards
