1. Lightweight Refractory Panels Multi-piece ceramic fiber panels enhance combus- tion while minimizing heat retention.

2. Fully-enclosed Headers

Temperature sensors and lead wires/capillaries are protected from weather, vandalism, and accidental damage during installation and service.

3. Flue Connection

Top or back outlet flue connections offer greater installation flexibility.

4. Air Filter

An easily-cleaned combustion air filter protects the burners from airborne particles including flying insects.

5. On-Board Diagnostic Center

Factory mounted standard equipment (302-2342). Gives relevant service feedback as well as possible solutions to clear the fault. All in plain English, no cryptic codes to decipher. The control stores up to 16 fault codes in its history file for the service tech- nician to review.

6. Status Display Lights

Up to 12 high-intensity LED lights, visible up-front, indicate the operating status of the boiler.

7. Construction

The cabinet and all internal parts are made from galvanized, aluminized or stainless steel. The exte- rior is protected by textured powder-coat paint, ideally designed for indoor or outdoor installations.

8. Central Point Wiring

Factory-made wire harnesses connect all electrical components to an easy-to-troubleshoot circuit board with multi-pin connectors.

9. Heat Exchanger Tubes Time-proven copper finned tubes and optional cupro-nickel tubes stand up to even the harshest water conditions.

10. Burners

Special stainless steel alloy pre-mix burners pro- vide clean, robust combustion and meet all low NOx regulations.

11. HSI Access Panel

A small panel provides access to both the hot sur- face igniter and the flame sensor to aid inspection and service.

On-Board Diagnostic Center

Raypak’s Hi Delta (302 thru 2342) comes equipped with a microprocessor-controlled diagnostic control center that displays its information on a 2x20 character LCD display in plain English. This control monitors system safeties, ignition faults and system status, while storing up to 16 reported faults. Raypaks diagnostic center also monitors the fault outputs of the Fenwal ignition control. The Fenwal’s flash codes are converted into real English fault codes that anyone can understand. The control is also equipped with a SPDT dry contact relay output that is switched anytime a safety fault occurs. This can be used for a heater alarm or a BMS safety interface.
