CAUTION
Do not put any tools or any other objects into the
combustion chamber.
1. Release the turnbuckles and screws M 12 on the
bottom of the boiler body, pull the boiler front section
out of the turnbuckles and remove it.
IMPORTANT
Do not use solvents. Use only clean towels and/or rags.
2. Secure supplied masking tape to all joints on the
inside of the combustion chamber to prevent sealant
adhering to these areas. Attach adhesive tape on the
rear boiler section approx. 8 to 10 mm behind the
front edge.
3. Evenly and generously apply the sealant supplied
into the annular groove on the front section of the
combustion chamber. Use supplied gasketing material
only.
4. The combustion chamber front portion must then be
aligned onto the main pressure vessel part and bolted
to the same with the two bolt clamps provided on
each vessel section together with the bolts and nuts
M16 x 150. Insert gasket on boiler connection flange
and tighten flange with nuts and bolts provided.
Attach lower section of front combustion chamber
to main vessel with nuts and bolts M12 x 25 as
provided.
5. Insert the supplied gasket in contact with the water
side between the boiler sections and connect the
proper flanges with nuts and bolts.
6. Secure the front section of the combustion chamber
at the lower end with screws M12 x 45 and nuts.
7. Using empty silicone tubes, remove all protruding
silicone sealant inside the combustion chamber.
Ensure sufficient sealant has been applied all around
to prevent any gaps appearing in the combustion
chamber. Using rubber gloves or a plastic trowel,
smooth the silicone joints.
8. Remove the adhesive tape when the sealant has
sufficiently dried (approx. four hours).
9. Position gaskets (in the pack supplied) onto both
top flanges and fit the pipework to the water side.
Connect flanges with supplied nuts and bolts.
