Raypak’s Next Generation
Modulating Boiler
Time-honored technologies unite with cutting-edge advancements in
Raypak’s MVB modulating vertical boiler. Never before has a vertical
boiler provided both the installer and building owner such installation
flexibility, ease-of-commissioning, reliability and long-term performance.
Small space, not a problem. The MVB 503A thru 2003A has the smallest
installed footprint of any vertical boiler, only 5.4 square feet. MVB models 2503 thru 4003 are just 11.7 square feet. Raypak’s MVB is built with
commercial-grade components and materials. From our structural steel
base to our stainless steel flue wrapper, you can tell the MVB is built to
last. It’s easy to handle and install, but still user friendly to service. Our
compact design fits through a 32” door opening making it the perfect
choice for those hard to reach retrofit projects. Now is the perfect time
to take a closer look at Raypak.
Flexibility
Small diameter vents and industry-leading vent length allowances
afford greater vent location options, thus reducing wasted space. Vent
versatility is further enhanced by the self-tuning combustion system
which compensates for unusual chimney and vent configurations.
Category I* -CSA-certified 84% boiler and up to 85% water heater
models available (504A-2004A). Our category I solution is the perfect
replacement for your retrofit applications. This reduces the installed
cost by using existing category I venting or chimney. Installation couldn’t be easier; all connections are on the back of the unit. Start-up is a
snap, it’s as close to plug-n-play as a boiler can get.
Category IV -CSA-certified 87% thermal efficiency (503A-2003A) and
85% thermal efficiency (2503-4003) at full fire–the highest possible for
non-condensing boilers (Up to 88.4% at part load!) When the job
requires high efficiency, our category IV solution meets your needs.
At the heart of every Raypak MVB is a unique integral evaporator system - the first defense against harmful condensation. Raypak’s evaporator system collects and re-evaporates condensate which may form during initial start-up or brief periods of cold-water operation, eliminating
the need for a boiler condensate drain. This saves you money on installation costs as well as the inconvenience of dealing with multiple condensate drains.
True Modulation
Modulation is nothing new to Raypak, we have honed our gas modulation experience for over 65 years. The Raypak MVB will precisely track
the heating load with its built-in Versa IC® Integrated Control platform,
eliminating costly overshooting. Utilizing the latest technology for the
blower-gas valve package, the optimum fuel-air ratio is maintained
throughout the entire range of the load-tracking operation. Now with
up to 7:1 turndown (503A thru 4003 Cat IV) ensures efficiency is maintained throughout the firing rate and actually increases during part
load, right when you want it! The MVB automatically self-tunes to
accommodate the widest range of gas supply pressures. The high quality integrated blower-gas valve is self-correcting and allows smooth
operation with fluctuating gas supply pressures. The Raypak MVB is
cutting edge technology with atmospheric simplicity.

Features and Benefits
1. Control Interface
Large easy to read (3.5”) LCD display. Will continuously
monitor flame strength (μa), sensor temps, BMS signal (0-10V),
set points, DeltaT, all safety signals, full diagnostics and fault history for last 15 events. Simple touch pad settings. Everything you
need from set-up to service is at your fingertips, all in one location.
1a. Versa IC Board (not shown)
The Versa IC, Integrated Control system is CSA listed and certified
as a combined temperature, safety, and ignition control device.
Easy front access to all field wiring. This includes outdoor sensor,
DHW sensor, system alarm, Modbus BMS port and 0-10V DC
input connections. Each unit comes factory equipped with cascade control capability. Simple, quick access daisy chain of up to
4 boilers, link to Raypak Temp Tracker Mod+ Hybrid Master control for up to 16.
1b. Low Voltage Wiring Connections (not shown)
Up front and easy to get to. Makes sensor wiring and external
control wiring simple and clean.
1c. Control Panel (not shown)
Fully enclosed controls and wiring protect against damage or
vandalism. Swing out cabinet design affords easy access to controls for installation and service
2. Status Lights and On/Off Switch
Easy to read and monitor boiler status. Colored lights alert maintenance personnel to power, call for heat, burner on and safety
fault.
3. Gas Valve
Designed to work in perfect harmony with the air blower. The gas
valve delivers the perfect fuel mix based on the amount of combustion air being supplied. The Euro designed gas valve provides
smooth light off and precise flame modulation with up to 7:1
turndown (503A thru 4003 Cat. IV).
4. Combustion Air Blower
Cast aluminum blower housing, non-sparking construction.
Precise PWM speed input allows for instantanous response to the
Versa IC control output. No blower lag associated with real time
water temperature sensing.

Cascade up to 4 Boilers
The MVB comes standard with a built-in Cascading Boiler
Control. No other controls to buy, just daisy chain the units
together with 2-wire shielded cable (not supplied) that connect to the front mounted low voltage wiring board.
Designate a Cascade Master Boiler and set all the other boilers as Followers. It’s that simple! The MVB has built-in
equal run-time rotation. This allows rotation of the starting
boiler so all boilers in the system remain active and the run
times remain equal on each unit.
Low Voltage Wiring Terminal
Control panel swings open for easy control access.

Smallest Installed Footprint
The MVB’s compact design allows for easy installation in the most challenging equipment rooms. It’s easy to handle and install, but still user friendly to service. The MVB
503A thru 2003A has the smallest installed footprint of any vertical boiler, only 5.4 square
feet. MVB models 2503 thru 4003 are just 11.7 square feet. The MVB contains all of its
components to the inside of the cabinet, so there won’t be any fans or valves hanging
off the cabinet that need extra clearance. The compact design fits through a 32” door
opening making it the perfect choice for those hard to reach retrofit projects.
Optional Equipment
Cold Water Solutions
Cold Water Start – For 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 valve to bypass water from
the boiler outlet to the inlet during startup, when the system return water temperature is below the
minimum acceptable level.
Cold Water Run – For applications
requiring constant condensation protection. 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.

Multi Boiler Solutions
Hybrid Control
BACnet BMS Link
TempTracker Mod+ Hybrid– Controls up
to 16 Raypak boilers with PID logic.
Automatic or manually selectable lead-lag
boiler operation. TempTracker Mod+ Hybrid
monitors and displays supply water temperatures on all applications including outdoor
temperature when outdoor reset mode is
selected. Can also be used to control a mix of
condensing and non condensing boilers using
our Hybrid control algorithm. Now available
with optional BACnet® MS/TP BMS link.
