Just fettled myself another IF54 heater (the blue one) ready to keep the workshop warm this winter. After getting over the dissapointment of the third (and final) 'new' 169 vaporizer being an old one in a box I just used the one it came with. Cleaning and painting was by a previous owner which saved a lot of time. I fitted some washers, a decal and made an intake from an old pump tube. Giving the reflecter a polish helps the heat coming out the front a lot. I now won't be letting the cold stop me from fettling this winter. Enjoy.
