1. What is the red glow in my gas Weil McLean pcg-4 boiler?
1b . My best guess is the red glow is insulation that has heated up and glowing red?
3. Does this insulation have Asbestos?
3b is it safe to breathe near this boiler ?
4 . What caused these scorch marks ?
( There is a mark on both sides of the boiler but the mark on right side is bigger)
4b is it safe to use this boiler with scorch marks ?( Boiler does not appear to be leaking)
