Raypak’s Hi Delta
Key Features
Decades of expertise and technological innovations went into
creating the Hi Delta boiler, a product that incorporates features
sought after by engineers, installers and end-users alike.
● 19 models from 100,000 to 2,340,000 BTUH
● All models indoor/outdoor certified
● Efficiency:
In 1948, Raypak introduced the first straight copper finned tube
boiler designed with reliability and serviceability in mind. The
tradition continues with Raypak’s Hi Delta model. It’s patented burner “security blanket,” an ingenious enhancement that provides a
perfected air-gas pathway for complete combustion, makes the
Hi Delta the most adaptable sealed-combustion boiler on the market
today.
84% Boilers- standard
85% AFUE HD101-HD301
87% Available on Models 302BE-2342BE
85% Water Heaters- standard
98% Condensing system available
(see Specialty Models)
The Hi Delta product family covers the full spectrum of both indoor
and outdoor applications including space heating, process heating,
pool heating and domestic hot water heating. When installed
indoors, the Hi Delta’s versatility is revealed in smaller vent
diameters, direct-venting and the convenience of stacking without
an increased footprint.
● Patented burner “security blanket” enhances staged
combustion, minimizes installation and start-up issues,
and protects burners from metal fatigue
● 105ºF minimum inlet water capability on standard models;
120°F on 87% boilers
● Copper finned tube heat exchanger; Cupro-nickel available
● AB 1953 low lead compliant
● Bronze headers standard on water heaters, optional
on boilers
● Sidewall venting ready; No extractor needed for
most applications

● D-21– TrueSeal direct vent air intake system
● A-6 – Right hand water connection
While many manufacturers claim simple, convenient heat exchanger
removal, servicing the Hi Delta couldn’t be more straightforward.
Just open the unit from the front and slide it out on built-in runners.
Adding to the Hi Delta’s ease of use is the On-board Diagnostic
Center. In the event of an operating problem, this key enhancement
allows an on-site technician to quickly review the unit’s entire fault
history, in easy to understand “real English”. No cryptic codes to
deal with. Our diagnostic center even offers possible solutions to the
problem at hand.

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 technician 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 exterior 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 provide clean, robust combustion and meet all low
NOx regulations.
11. HSI Access Panel
A small panel provides access to both the hot surface 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.

Cold Water Start
Cold Water Run
Cold Water Solution Options
Cold Water Start
It is commonly known that prolonged internal condensation will dramatically shorten the life of standard boilers and water heaters. While
Raypak boilers and water heaters can operate without harmful condensation at lower inlet water temperatures than the competition,
there are still applications that require reliable protection against harmful condensation caused by frequent, extended, cold water startups. Raypak’s Cold Water Start protection system utilizes a proportional three-way valve to bypass water from the boiler outlet to the
inlet during start-up, when the system return water temperature is below the minimum acceptable level.
Cold Water Run
For the same reason stated for Cold Water Starts, it is even more important to provide protection against condensation from cold inlet
water on systems where the return water temperature to the boiler will always be below the acceptable minimum. Raypak’s Cold Water
Run system utilizes a variable-speed pump to inject just the right amount of water from the main system loop into the boiler to maintain
the optimum inlet temperature. This approach allows the full capacity of the boiler to be utilized to meet the system load, while at the
same time continuously maintaining the optimum inlet water temperature to prevent condensation.
(See Cat. #1000.19)
Simple Serviceability
Control Options
Raypak’s easy-to-understand user interface, including onboard diagnostics and LED operating status lights, tells
the technician all he needs to know. All service/repair
components are readily accessible from the front for maximum installation flexibility.
Raypak’s array of leading edge controllers offer features such as:
sequence-control of up to 40 boilers; PID technology; optimized
approach to outdoor reset; LonWorks or BMS interfacing; freeze protection and other energy-saving functions. Raypak’s controllers have
been specially designed to maximize the performance of its leadingedge Hi Delta boilers.

NOTES: 98% efficiency available with condensing heat exchanger. (See Specialty Models on pg. 4.) Minimum flow rates in closed systems may be reduced to a flow rate consistent with a 40°F ⌬T.
Maximum flow rates are limited by maximum acceptable velocity through the heat exchanger tubes and may be increased by 10% for closed heating systems. Pressure drop would increase 21%.
*SHL = Calculated at 100 feet effective pipe length.
