2.1. For your safety, we recommend that:
Make sure you fully read and understand this instruction manual before using the free
standing pellet fire as a biomass heating unit.
Make sure that the hydraulic circuit was correctly assembled and connected to the
water supply before turning on the free standing pellet fire (only in water models –Douro
17kW and Douro 23kW);
The free standing pellet fire is not intended for use by children or persons with
reduced physical, sensory or mental capabilities, or lack of experience or knowledge,
unless they are under supervision or have been instructed concerning the use of the unit.
Do not touch the free standing fire when barefoot or if any part of your body is wet or
humid;
Do not tamper with safety or adjustment features without the manufacturer's
authorization;
Do not cover or reduce the size of the vents at the installation area;
The free standing pellet fire requires a clear space around the unit for proper
combustion, so possible air tightness of the location or any existing air extraction sources
in the room may prevent the unit proper operation;
The existence of vents is a requisite for proper combustion;
Do not leave the packing materials near children;
During normal operation, Free Standing Fire unit's door must not be opened;
Some parts of the unit may overheat during normal operation, so avoid direct contact
with parts such as the door handle and glass;
Check the existence of any obstructions on the fume duct before turning on the unit
after a long period of inactivity;
This free standing pellet fire unit is intended for residential use in protected areas.
Safety systems may turn off the unit. If this occurs, contact the technical assistance. In
any circumstances should you attempt to interfere with the safety systems;
The free standing pellet fire is a biomass heating unit equipped with an electric fume
extractor. The occurrence of any power failure during its use may prevent fume
extraction and the room will be filled with smoke. For this reason, you should have a
natural fume extraction system, like a chimney, available;

6
Solzaima offers you an optional safety system which allows the Free Standing Fire
unit to be connected to a UPS so that during any power failure the fume extractor will still
operate until complete extraction of all the fumes;
If you intend to use the Free Standing Fire unit while you are away from home or
unattended, you should use the safety system specified above for total safety during any
power failure;
During operation, NEVER turn off the free standing fire unit by disconnecting the
electric plug. The fume extractor on the free standing pellet fire unit is electric so
disconnecting the power plug will prevent the extraction of combustion fumes;
Your unit must be disconnected from the mains for servicing. Before doing this, the
unit must be totally cooled down (if operating before);
Never touch the interior of the unit without disconnecting it from the power mains;
On backboiler models, the maximum temperature of the water that can be set by the
user (water set-point temperature) is 85°C. In the event of a temperature of 90ºC being
reached, the free standing pellet fire unit automatically disconnects and the respective
alarm is activated.

4.2. Installation requirements
The minimum distance between the free standing pellet fire unit and particularly
flammable surfaces is specified in Figure 15.
The top of the unit must be at least 100cm separated from the ceiling, especially in
rooms with ceilings consisting of flammable materials.
The base supporting the unit cannot be made of combustible material (e.g. carpet), so
make sure you use an adequate protection.
a) b)
Figure 15 –Minimum distances from all surfaces: a) upper view of the unit's installation;
b) side view of the unit's installation
Warning!
Keep combustible and flammable materials at a safe distance.
4.3. Installation of ducts and fume extraction systems:
The exhaust pipe must have been designed for this purpose, in compliance to the
location requirements and in accordance with any applicable regulations.
Important! An inspection-T with an airtight lid must be attached to the exhaust
pipe of the unit to allow the regular inspection of the system or discharge of heavy dust
and condensates.

17
As indicated in Figure 15, the exhaust pipe must be assembled so as to allow
cleaning and maintenance of the pipe by inserting inspection points.
Under normal operating conditions, the combustion gas flow should create a draught
of 12 Pa one meter above the chimney neck.
The unit must not share the chimney with other equipment.
Pipes outside the operating area must have double stainless steel insulation and an
internal diameter of 80 mm (air model) or 100mm (backboiler model).
The fume exhaust pipe may generate condensation, so we recommend that the
appropriate systems for collecting condensates should be installed.
4.4. Installation without a chimney
The installation of the free standing pellet fire without a chimney should be performed as
illustrated in Figure 16, equipped with an exhaust pipe (with a minimum diameter of 80
mm for the air model and 100 mm for the backboiler model) directly outside and over
the roof.
Double-walled stainless steel insulated pipes must be used and properly fastened to
avoid condensation.
A T-tube must be installed at the base of the pipe to allow periodic inspections and
annual maintenance, as illustrated in Figure 16.
Figure 17 specifies the basic requirements for installing the chimney to the unit.
