REPLY:
100 CFM is a lot of air. You might try slowing the blower down while
monitoring the tube seal temperature at full output. The critical
points on the tube are where ceramic and metal meet. Use the temps
specified in the data sheet.
Also, be sure all the air is going to the tube and not leaking around it
or leaking elsewhere. If you already have a tight fitting chimney, fine,
but if you don't, a replacement glass from a Coleman lantern fits
perfectly. Be sure to measure before you buy - there may be different
sizes. I installed mine with a few dabs of RTV silicon. Solid mount and
easily removed when you need to.
Color-sensing paint and crayons are available from McMaster-Carr and
others.
