C24GA SERIES GAS CONVECTION STEAMERS
PLUMBING CONNECTIONS
WARNING: PLUMBING CONNECTIONS
MUST COMPLY WITH APPLI-
CABLE SANITARY, SAFETY
AND PLUMBING CODES.
Water Requirements
Proper water quality can improve the taste of
the food prepared in the steamer, reduce
liming in the steam generator and extend
equipment life. Local water conditions vary
from one location to another. Ask your
municipal water supplier for details about your
local water supply prior to installation.
Presence of sediment, silica, excess chlorides
or other dissolved solids may lead to a
recommendation for alternate form(s) of water
treatment. Test the water with a TDS meter or the
test strip included with the steamer. Other factors
affecting steam generation are iron content,
amount of chloridation and dissolved gases.
Water Treatment
A local water treatment specialist should be
consulted before installation of steam
generating equipment.
Supply Pressure 20 - 60 psig
Hardness* less than 3 grains
Silica less than 13 ppm
Total Chlorine less than 4.0 ppm
PH range 7 - 8
Undissolved Solids less than 5
microns
*17.1 ppm = 1 grain of hardness
If the water supply fails to meet these
standards, it will be necessary to install a
water conditioner on the generator water feed.
The use of strainers or filters will not remove
minerals from the water.
Water Supply Connection
Connect the treated cold water supply line to
the
3
/8" NPT inlet at the rear of the steamer.
Connect the untreated cold water supply line
to the
1
/8" NPT, also at the rear of the steamer.
NOTE: Models manufactured after June 2006
may have
3
/4" hose connections.
A water filter system is recommended for the
water supply line going to the treated water inlet
of your steamer. Follow the recommendations
for use and installation instructions shipped
with the water filter. If a water filter is not
installed, the steamer or steam generator
warranty will be limited.
Filter System
If you decide to not install a scale reducing
filter system designed for steam equipment
or use another manufacturer’s system other
than recommended by Vulcan Hart, please
use these guide lines.
• If you are going to delime the unit with a
deliming agent recommended for a
pressure steam boiler and stainless steel
generators and you are on city or treated
well water, you still must have a carbon
block filter installed and maintained.
Carbon block filters remove the chlorine
and chloramines disinfectants from the
water. Chlorine and chloramines will erode
the boiler or steam generator and will
result in a vessel failure which is not
covered under warranty.
• Water feed lines to the steamer must be
flushed before final connection. Particles
in the water could build up in the water and
steam valves or clog tubing and
components that maintain the water level
and pressure in the boiler or steam
generator. If the water supply is not free of
sediment or cloudy after several minutes
of flushing, a sediment filter must be
installed before use.
