TROUBLESHOOTING

DRAW-OFF VALVE LEAKS

If a leak occurs through the valve stem, replace the “O”
ring.

If the leak can be attributed to faulty sealing occurring
between the stem disc and valve seat, then this problem
may be corrected by cleaning off the dried-on food resi­due with extremely ne emery cloth. If the vulcanized rub­ber stem piece has been damaged, it must be replaced.

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. This is not
covered under warranty.

EXTREMELY SLOW COOKING TIME

If the cooking time is abnormally slow, this may be due
to insufcient 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 sufcient.
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 supply pipe will be required. Finally, the core
of the steam supply pipe may have debris or scalants that
impede steam ow and will require disassembly and in­spection.

VENTING

It is recommended that the “optional” steam trap assem­bly be installed. This should be plumbed to the exit end
of the kettle. The thermostatic trap is a mechanical de­vice that closes on high temperature and opens when the
temperature drops, allowing the water which formed from
condensate to exhaust but retain the steam under pres­sure.
