C24GA SERIES GAS CONVECTION STEAMERS

PLUMBING CONNECTIONS

Plumbing connections

must comply with applicable 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 ¾" 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.
