Flash Curtain / Heat Shield
Principles of the Flash Curtain / Heat Shield
The purpose of the ash curtain is to decrease the
amount of smoke emitted from the door when loading
coal into the rebox. The ash curtain decreases the
size of the rebox opening, making that size more in
proportion to the area the natural draft of the chimney
will draw from. As a heat shield, the ash curtain
restricts the amount of direct heat that contacts the
rebox door directly.
Maintenance/Result
Leaving the ash curtain in place is effective for the
principles outlined above.
Removal and Replacement
1) The plate is slotted at the top and ts loosely onto
two hooks, installed above the rebox door opening.
2) With the ashes cooled down, lift up on the plate
until it releases itself from the hooks.
ABSOLUTELY NO FIRE IN THE FIREBOX WHEN
PERFORMING THIS REPAIR. ALWAYS WEAR
PROPER PERSONAL PROTECTIVE EQUIPMENT.
