INSTRUCTIONS
Boiler size should correspond with the house's heating requirements and not be made to
depend on the size of the filling chamber.
The heating engineer must possess the necessary training and authorisation to install the
boiler.
The flue gas temperature in a clean boiler is about 150°C.
The chimney should be able to accommodate this temperature.
As the Solo Innova has a built-in fan, only minor demands are made on the chimney
draught. The correct chimney draught is 10-15 Pascal. The chimney can therefore be
lower than for the usual solid fuel boilers. Relevant standards and regulations must be
observed for the chimney shape. An excessive diameter or inadequate insulation can
result in sooting. Please consult a chimney sweep.
We recommend connecting the boiler's exhaust stack back to the chimney at an angle or
horizontally.
The exhaust stack can also be connected vertically, but the fan impeller must then be
removed each time the chimney is cleaned and ash/soot removed.
draught limiter
Strong directional wind or a very high chimney can cause such a high chimney draught
in some circumstances that combustion continues even though the fan has been switched
off. The solution here is building in a draught limiter so that the chimney draught can be
set to 10-15 Pascal. The chimney sweep should be consulted first. A draught limiter is
available from BAXI as an accessory for the boiler (A solid draught limiter in stainless
steel with outer bearing and good control accuracy). The draught limiter can be built in,
in positions 1-2 or 3.

Set up the boiler on a stable base.
Adapt the connector to the chimney.
1. The suction draught fan must be installed (with four wing nuts and washers) before
the casing is attached.
2. The casing should be attached as indicated in the accompanying photographic
instruction.
3. Place the sensors into the immersion tube. The capillary pipe must be bent
carefully and "softly". The long thin sensor should be placed in collar no. 12 for
the suction draught fan – see Section 4.1, Technical specifications. Place the other
sensors in the immersion tube (21) – see Section 4.1.
4. Connect pipes.
5. Connect power.
6. Install the casing cover and tighten with the four screws.
