FURNACE GRATES & TRAYS

For Wax Elimination Cycle

The WW Furnace Grate and Tray simplifies burnout procedure. It is no longer necessary to remove flasks and tray, then
replace flasks to avoid carbon build-upon heating elements, which is a primarycause of element failure. Now you merely
slide the stainless steel tray(s) from beneath the grate at the end ofthe wax elimination cycle and proceed withburnout.you
have removed 90% or more of the cause of offensive odor and air pollution. The grate is cast iron, like a cook-stoveburner,
for strong support and long life.

Grates and trays are sized to fit standard electric burnout furnaces.
