On models with pump and/or solenoid valve, connect

incoming water supply to intake side of solenoid valve.

AR & ARH steam boiler models require four (4) gallons of

feed water per hour for each 10 kW of electric heating

capacity of the boiler. Lines should be of adequate size and

meet local plumbing codes.

In order to ensure long term troublefree boiler operation,

we recommend that the water used as boiler feed water to

be tested for hardness. If the water in your area is harder

than 1grain (17mg/L), use a water softener. The main

cause for premature heating element failure in electric

steam boilers is water hardness. If severe corrosion during

inspection of the pressure vessel as indicated in chapter

3.4 of this manual becomes evident, additional tests of

your boiler feed water must be performed. A water analysis

should be performed by a qualified and recognized water

treatment company located in your area.

Recommended levels for boiler feed water:

Recommended levels for boiler water (water inside

pressure vessel when boiler is operating)

All piping from and to the boiler must comply with the

A.S.M.E. B31.1 Power Piping Code. All State and local

codes must be met. All piping must be done by a qualified

steam fitter.

Connect steam line of sufficient size from steam line valve

to the equipment. Steam piping must be black steel pipe,

not galvanized. Work must be done by an experienced

steamfitter. All state and local codes must be met.

The safety valve is designed to discharge hot steam when

the set pressure is exceeded. Ensure that the discharge

port is pointing toward the back of the unit away from the

operator and any aisles. If it is required that discharge

piping be installed from the safety valve, the pipe should

not be smaller than the valve outlet and should be rigidly

supported so as not to place weight on the valve itself.

Important: No valve in this line!
