DIRECT STEAM KETTLES
INSTALLATION PROCEDURE
Make sure the kettle is in its
fi
nal location before performing the installation procedure.
It may be necessary to increase the height of the kettle when leveling to clear the draw-off valve on
tilting kettles. Use the adjustable
fl
ange feet to increase the height of the kettle.
1. Place a spirit level on the rim of the kettle with the cover open. Adjust the feet to level the kettle
left-to-right and front-to-back.
2. Mark anchoring hole locations through the
fl
anged feet, then move the kettle out of the way.
3. With hole location marked, drill holes for expansion plugs for appropriate-sized lag bolts.
4. Reposition the kettle and verify that the kettle is level.
5. Bolt the kettle down and apply an NSF-approved silicone sealant around the bolt heads and
fl
ange making contact with
fl
oor surface. Wipe off excess sealant immediately.
STEAM SUPPLY CONNECTION
The steam line plumbing diagram (Fig. 1) is a generic representation of the recommended steam
supply.
Fig. 1
If the incoming steam pressure is greater than kettle maximum operating pressure stamped on the
nameplate, install a pressure-reducing valve (not supplied) on the line before the steam inlet to the kettle.
Connect steam supply line (see chart) pipe size to the kettle inlet
fi
tting making sure there is a steam
control valve strainer. The steam supply line must be as large as the steam inlet
fi
tting.
The relief valve on the kettle must not be closed off as it is set to relieve excess pressure in the kettle.
If the steam is heavy with condensate, install a steam trap before the pressure regulator valve. To
ensure rapid heat-up of heavy loads, a ball
fl
oat type steam trap is recommended. Steam trap should
be sized for
fl
ow-rate and differential pressure. The steam supply line must be sized to maintain
pressure and
fl
ow (see chart).
A steam line pressure gauge (not supplied) is recommended to determine the actual steam pressure
being supplied to the kettle.
Install the steam shut-off valve at a convenient location near the kettle on the incoming steam line.
