INSTALLATION

WARNING: To avoid electrical shock hazard, boilers must be suitably grounded to earth.

Note: Chromalox boilers are pre-tested before shipment; no inter-

nal piping or wiring is necessary. WARNING: Substitution of components or modification of wiring without prior consent of Chromalox voids warranty.

1.Bolt unit securely to level floor or platform.

Note: A minimum distance of 18 inches from wall, other equipment, etc. must be allowed for removal of the elements.

2.Complete all piping to boiler. Connect water line to tagged fit- ting on the motor and pump assembly if used, or to tagged fit- ting on water control feeder.

3.When any type of feed other than a pump feed is used, the water supply line pressure must be 10 pounds greater than the boiler operating pressure to assure proper water level in boiler. Lack of water can cause heater failure. Keep feed water line valves open at all times.

4.Connect steam line (with outlet valve) to boiler steam outlet.

5.Open all gauge valves and steam outlet valve; keep drain valve closed.

Note: The safety valve should be provided with a drain line sized no less than the outlet size of the valve and routed per local codes.

6.Floor drain to be provided directly below unit.

WIRING

WARNING: Hazard of Electrical Shock. Disconnect all power before working on boiler. Boilers must be grounded in accordance with the National Electrical Code (NEC) standards to avoid shock hazard.

WARNING: Use 90°C copper conductors only.

1.Select proper wire gauge and type for supply conductors in accordance with the National Electrical Code and local wiring codes following wiring diagram supplied (See recommenda- tions for disconnect switches and fusing).

Note: Purchaser should use a safety disconnect employing cir- cuit breakers or fuses between the main power source and the boiler. This overcurrent protection should be installed in addi- tion to any other supplementary fuses or circuit breakers pro- vided as an integral part of the boiler.

2.If a separate control circuit is used, the control circuit should be connected to the control terminal block and the circuit pro- tected by overcurrent devices in accordance with the National Electrical Code.

3.Chromalox boilers are solid state devices. Since boilers are connected to water lines, these devices are susceptible to volt- age surges and lightning damage. Industrial type lightning pro-

tectors should be installed per manufacturer’s recommenda- tions at your service entrance.

4.Be sure that all electrical connections are sufficiently tight- ened. Loose connections will cause overheating and damage to the electrical wiring.

5.Special instructions for customers supplying their own con- densate or pump system.

A.Check the voltage of the motor before making the wiring connection. The motor should always match the voltage of the control circuit. Standard control circuit voltage is 120 volts ± 10 volts.

B.Internal water feed relay is rated at a maximum of 1/3 H.P., 120 volts. Motors rated greater than 1/3 H.P., or other than 120V, single phase, require the use of a suitable motor starter.

6.After all service connections are made, open feed water supply valve and energize the boiler. The feed water solenoid will open, fill the boiler to the proper water level and automatical- ly shut off. The feed solenoid will continuously cycle on and off as the boiler requires water. If, for any reason, the water drops below the minimum safe operating level, the boiler’s electrical circuits, except the feed solenoid will be de-ener- gized automatically. Upon refilling to the proper level, the boiler will automatically restart.
