CONTROLS

Controls – All basic controls and terminals are located in an integral ventilated control cabinet, factory wired and functionally tested. Controls include Class K fuses with 50,000 ampere interrupting capacity, magnetic contactors UL Listed for 100,000 cycles, 120V control transformer with primary fuses, low water cutoff, operating controller, automatic reset high temperature cutout, and control circuit lighted switch.

Low Water Cutoff – In the event of a low water condition, low water cutoff interrupts control circuit to protect elements from damage caused by overheating.

Automatic Reset High Temperature Cutout(s)

– De-energizes control circuit in the event of a high temperature condition.

Control Circuit Lighted Switch – De-energizes control circuit (not main power).

Operating Controller – Maintains water temperature at predetermined setting.

Pressure Relief Valve – Vents pressure to atmosphere in the even of high pressure in excess of relief valve setting.

Pressure/Temperature Gauge – Combination gauge provides visual indication of water temperature and pressure. Mounted on outlet pipe.

Optional Accessories – Optional built-in or remote accessories may be included as called for in job specifications. Instructions covering adjustments and servicing of these accessories are supplied with the unit.

MAINTENANCE

A periodic check of all control components will ensure proper operation.

1. Check wiring and terminations for tightness.

2. Check all controls and safety devises for proper operation.

3. Check pressure relief valve to ensure that it is not leaking and that no corrosion exists.

4. Check circulator pump and lubricate according to manufacturer’s instructions.

At least once a year, boiler elements should be checked.

1. Disconnect all power to boiler.

2. If a faulty open element is indicated, the element may be replaced in the following manner:

a. Isolate boiler from system by closing hand valves in supply and return piping.

b. Drain boiler completely of water.

c. Remove ALL wiring from the elements, tagging both the wires and element terminals.

d. Mark element flange position with respect to the vessel flange for proper alignment upon reinstallation; remove flange bolts.

e. Remove the element flange from the vessel.

f. Remove element retaining nut using a 11/16 socket wrench.

g. Remove ferrules (2 compressed rings) from the element ends and remove element from back side of flange.

h. Insert new element and ferrules and tighten element retaining nuts into flange.

i. Replace flange in boiler vessel using new gasket. Align previously made marks on flanges and install flange bolts, torqueing each bolt to 70 foot pounds (minimum).

j. Reconnect electrical wiring, making sure all wiring is connected to the proper element termination.

k. Refill boiler following procedure listed in INSTALLATION section.

l. Check elements and flanges for leaks.

m. Replace vessel enclosure cover.

LOCATING TROUBLE

Problem Possible Cause

1. Unit does not operate Disconnect or control circuit switched off, low water condition, high temperature condition, improper setting of operating control.

2. Water temperature too low Operating control set too low or not operating properly, oversized circulator pump, or faulty elements/fuses/contactors/wiring.

3. Water temperature is too high

Operating control is set too high or not operating properly, undersized circulator pump or not operating properly.

4. Water temperature correct but building is cold

Circulator pump not operating properly, air blocks in piping or radiation, control valve in supply or return piping not fully open.

5. Excess pressure causing relief valve to open

System head pressure exceeds relief valve setting or expansion tank water logged.
