1. Light weight Refract ory Panels
Multi-piece ceramic fiber panels enhance combus-
tion while minimizing heat retention.
5. On-Board Diagnost ic Cent er
8. Cent ral Point Wiring
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.
Factory-made wire harnesses connect all electrical
components to an easy-to-troubleshoot circuit
board with multi-pin connectors.
2. Fully-enclosed Headers
Temperature sensors and lead wires/capillaries are
protected from weather, vandalism, and accidental
damage during installation and service.
9. Heat Exchanger Tubes
Time-proven copper finned tubes and optional
cupro-nickel tubes stand up to even the harshest
water conditions.
6. St at us Display Light s
Up to 12 high-intensity LED lights, visible up-front,
indicate the operating status of the boiler.
3. Flue Connect ion
Top or back outlet flue connections offer greater
installation flexibility.
10. Burners
Special stainless steel alloy pre-mix burners pro-
vide clean, robust combustion and meet all low
NOx regulations.
7. Const ruct ion
4. Air Filt er
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.
An easily-cleaned combustion air filter protects the
burners from airborne particles including flying
insects.
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.

SureRackTM Kit
See Cat. 1000.16 for
complete SureRack Details
The perfect solution for today’s most space challenged equipment rooms.
Stacking two Hi Delta 2342 boilers provides over 4.6MMBTU in just over
26 square feet plus clearances. All components (except pumps and PRV’s)
are contained inside the cabinet, so there won’t be any gas valves or fans
hanging off the unit. The units remain fully serviceable even while racked.
• For models 302 thru 2342
• No Vent Offset Required
• Small Footprint
• Fits in Low-Ceiling Room
• Heavy-Duty Construction
• Easy Assembly
• All Hardware Included
• Still Allows for Complete Servicing
98% High-efficiency Hi Delta w ith optional CHX
condensing heating system
Hi Delta with CHX achieves unequaled 98% thermal efficiency at full fire. It combines
the reliability of the Hi Delta boiler with an optional CHX heat exchanger which pre-
vents condensation in the heater’s primary combustion chamber. Self contained sec-
ondary heat exchanger can be inspected and maintained without disturbing the vent
or plumbing connections. The result is an ultra high efficiency heater that lasts.
(See Cat. 1000.17)
• For models 402 thru 2002
• Indoor/Outdoor installation
• Top or rear CHX mounting options
• Fully certified vent systems available
• Up to 4.0MMBTU if used with the
SureRack racking system
• Fully-engineered rack systems simplify
jobsite installation and set-up
• Straight tube heat exchanger outlasts
other designs and facilitates scale-
free operation – ideal for DHW
applications
Flex GasTM
Dual-fuel boilers and w ater heaters
With its patented, CSA-certified rapid fuel switchover system, the Hi Delta FlexGas
is an ideal solution for interruptible-fuel applications (natural/propane gas).
(See Cat. #1000.20)
• For models 302 thru 2342
• Changeover takes less than one minute
• Changerover can be accomplished
while firing: simply turn the key!
• Factory-installed and tested system
• CSA-Certified
• No mechanical components to remove
or replace

Cold Water Start
Cold Water Run
C o ld W a te r So lu tio n Op tio n s
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 start-
ups. 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 on-
board 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 max-
imum 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 pro-
tection and other energy-saving functions. Raypak’s controllers have
been specially designed to maximize the performance of its leading-
edge Hi Delta boilers.

2342BE 102
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.
