NOTICE: Draw-off valve has a vulcanized rubber coated stem for better
sealing. Do not over tighten. This may cause the rubber to pull away from
stem and permanently damage it.

DRAW-OFF VALVE LEAKS
If a leak occurs through the valve steam, replace the “O” ring. If the leak can be attributed to
faulty sealing occurring between the stem disc and valve seat, then quite often this problem can
be corrected by cleaning off the dried on food residue with an extremely fine emery cloth or the
rubber vulcanized stem piece has been damaged and must be replaced.
EXTREMELY SLOW COOKING TIME
If the cooking time is abnormally slow then the difficulty may be due to insufficient steam
pressure and/or volume. First determine that pressure on incoming steam line at kettle is within
5 p.s.i. of rated kettle pressure. Note that pressures approaching the rated kettle pressure are
liable to set off the safety relief valve. If required pressure is available to kettle, then possibly
volume of steam is not sufficient. Minimum 3/4" pipe size is required to the kettle but if the
steam generating source is at a great distance from the kettle, larger pipe will be required.
Finally, the core of the steam supply pipe may have debris or scalants that impede steam flow
and will require disassembly and inspection.
