I HAVE A DIMPLEX JAZZ FIRE JAZ20R. APPROX 2 YRS OLD. I HAVE RECENTLY CHANGED THE BULBS AND FUSE BUT GET NOTHING. IT DOSEN'T LIGHT UP AND THERE IS NO HEAT COMING THROUGH. IT HAS HAD VERY LITTLE USE SO WHY WONT IT WORK, I CAN'T THINK OF THERE BEING TOO MUCH WRONG WITH IT. I WANT TO GET HOLD OF A MANUAL TO SEE IF THERE ARE ANY CLUES ON THE TROUBLE SHOOTING PAGE.
