CER & P-ER Electric-Hydronic Water Boilers
CER 3 sizes: 82,000 to 137,000 BTU/Hr.		P-ER 3 sizes: 51,000 to 85,000 BTU/Hr.

Product Features:

Cast Iron Construction:
The one-piece cast iron boiler section is built in accordance with the requirements of the A.M.S.E. boiler and pressure vessel code. Large water content eliminates rapid internal temperature changes to assure better control response and nearly constant supply temperature. The section is insulated with fiberglass to reduce heat loss. A built-in air separator at the top of the casting diverts air bubbles to the automatic air vent or expansion tank...no separate air eliminating device is necessary.

Heavy-Duty Jacket:
The steel jacket is finished in attractive blue hammerloid with a hinged front door to permit access to all internal components.

Heating Elements: Incoloy-sheathed, low-density elements resist the corrosive effects of all chemicals found in domestic water systems.

Factory-Wired Controls:
All controls are factory wired, and standard electrical components are used. The componentized control system provides the advantage of easier replacement at lower unit cost.

Internal Fusing: CER and P-ER boilers are supplied with separate fuses for each element leg. This safety feature eliminates the need for additional external sub-fusing.
