General Specifications
The STREBEL Camino 7s is a special boiler for oil or
gas fired pressure jet burner.
In the BICALOR construction a calorifier for the
supply of hot water is built onto the boiler.
CSH-S type calorifiers are manufactured from 1.4571
high tensile steel with an incorporated heating coil of
galvanised copper ribbed pipe.
Triple pass block of cast iron sections.
The first pass is the combustion chamber. From there
the flue gases pass between the rear section and the last
intermediate section through the second pass to the
front of the boiler. They are then diverted into the third
pass and flow back to the rear through the flue spigot
into the chimney.
Flue baffles of cast iron can be introduced into the flue
passes in order to influence the flue gas temperature
depending on chimney conditions.
The boiler can be used with an oil or gas burner.
Brief description.
• Corrosion resistant block of cast iron sections.
• Triple pass boiler with optimised use of energy.
• High efficiency.
• Built-in instrument panel with multiple control
possibilities and retro-fit control options.
• Easy erection and cleaning.
• Modern design.

The boiler can be delived in individual sections
or as a boiler block. The accessories are packed
seperately. There are different orders of
assembly depending on the condition of supply.
when assembling and connecting the boiler, all
relevant instructions should be observed.
The boiler is to be erected on a base, or a level
floor which is capable of supporting the weight
of the boiler, water content and any ancillary
equipment. Refer to base details opposite.
Assembly, connections and the initial set-up
operation should be carried out by a qualified
heating engineer.

Diagram showing clearances required in boiler room.
The clearance details shown above are required for access to the boilers for maintenance purposes. Slight
variations may apply, depending on the specific installation.

Once assembled, the boiler block is to be secured with
the tie bars (2 at the top, and 2 at the bottom). Prior to
screwing nuts up ensure the two disc springs (5)&(6)
are slotted on with concave sides facing each other.
The nuts can now be tightened until the disc springs
flatten.
The burner door hinges should now be fitted on the
left or right hand side of the front section depending
on requirements. Ensure the eyelet screws (door
hinge) are at the same depth and when the door is
closed it should press flat with the front section.
Boiler Block Assembly
The boiler block is assembled by ‘pulling-up’ each
section in turn starting from the rear section (1). All
other sections (2)(3)(4) are mounted individually
using the pulling-up tools.
One face of the adjoining sections must have a length
of mastic sealing strand placed into the mastic groove.
Each of the boiler nipples must be inspected to ensure
there is no damage apparent. The nipples and nipple
ports should then be kept free from dirt and checked
at each stage of assembly. Particles of dirt which are
not removed lead to leakage.
The accompanying nipple jointing oil serves as a
lubricant as well as a waterproof seal and must be
used.
Boiler nipples and nipple ports must align exactly at
all stages of assembly. An inclined, retracted nipple
leads to leakage.
The clearance between the sections throughout the
pulling-up stages should always be even. If the
clearance is uneven, a flat chisel should be inserted
into the narrower point and the sections pulled up
until the clearance is even again.
