The advantages of sealed combustion

While the boiler in your home is heating, it requires about a room-full of air per hour for proper
combustion. Conventional boilers, installed in older houses or homes that are not well insulated, use
room air which is replaced through leaks in the wall or cracks around windows and doors. Room air,
however, is air that you have already paid to heat.

Direct vent “sealed combustion” boilers, in contrast, use a dedicated and sealed, fan-powered system
to draw air in from outside the house and to vent the products of combustion directly outside.

Sealed combustion boilers are ideal for new homes which are tightly insulated to conserve energy, as
well as for older homes that would like to improve energy efficiency.

Cabo2 offers a variety of venting options

Sealed combustion boilers are designed for through-the-wall venting where a chimney is not available
or when a chimney becomes unusable. Cabo2 is designed for direct venting but can be utilized as a
conventional induced draft boiler, and provides for venting options in both applications.

CROWN offers coaxial vent terminal kits for both horizontal and vertical venting. Consult our
installation manual for specific venting requirements.

The power of the Cabo 2 and the efficiency of
the Mega-Stor indirect water heater

Together, they assure you’ll have all the domestic hot
water you need, heated with more energy than is ever
available with direct fired water heaters. More energy
means more hot water.

Mega-Stor means…

• Abundant domestic hot water

• Heated by your high efficiency boiler to save energy

dollars

• Adjustable temperature control

• Well insulated to keep water hot for hours

• Removable cap for easy access to tank and coil

• Sizes from 26 to 119 gallons to meet every home and

apartment owner’s needs

• Lifetime full warranty on stainless steel coil and tank

assembly (See Mega-Stor warranty for details)

made for each other

...ideal for today’s

homeowner who
is looking for a
more energy
efficient boiler

Energy Star qualified; efficiency exceeds 85% A.F.U.E.

Proven reliability: designed with the benefit of CROWN’s

years of experience, employing technology proven in service,
with the newest in controls to optimize operation.

Powered intake and venting

saves energy dollars by using combustion air from outside,
rather than room air you’ve already paid to heat, and assures
that all exhaust gases go directly outside.

System controller provides

two zones, with ability
to prioritize the zone
connected to a Mega­Stor indirect water
heater.

Plug-in
outdoor temperature
reset control

is an

optional feature.

Self diagnostics, with

LED indicators, show
status of boiler
operation. Boiler may
be ordered without this
control system.

Pressure switch

monitors operation
of the venting system.

Electronic ignition–

Spark-to-pilot ignition
saves fuel. Step­opening gas valve
provides smoother
ignition.

Sealed combustion:

isolates the combustion
in your boiler from the
air in your home.

Stainless steel burners

give quiet, trouble-free
operation.
