SPECIAL RECOMMENDATIONS FOR THE CHIMNEY INSTALLATION AND MAINTENANCE
The way the appliance chimney duct is installed, whether it is a heater, fireplace or
compacto for solid fuels, will definitely have an influence on the safety and its good functioning.

1.2- CHIMNEY INSTALLATION FOR SOLID FUELS.

1.2.1- FLUE SYSTEM COMPONENTS.

A flue system has several components:
Connector to the appliance, cleaning register, cowls, draught cutting valve, insulating roof and
wall protectors, insulating bushings, coverings, protecting chambers, etc.,.... and the chimney
duct.
To safely install a heating appliance, it is absolutely necessary to install all these elements
following the standards established by the manufacturer, especially regarding the distances to
the combustible surfaces.
Chimney Connector
• The chimney connector is the run of tubes that links the heater with the chimney. The
chimney connector must have the manufacturer's specified diameter. The material will be
special steel for flue tubes, either with an anti-caloric paint protection, vitrified enamels, or,
stainless steel with refractory characteristics. In general use the tubes manufactured for this
function.
• Never use aluminium or galvanised sheet. These materials do not withstand the extreme fire
temperatures.
• The chimney connector must be the shortest possible, avoiding, when possible, horizontal
sectors and elbows at 90º. The use of horizontal tubes or too many elbows increases the
loss in draught and the accumulation of creosote in the chimney.
• In the case of fitting horizontal sectors, it is recommendable to have a minimum ascending
inclination of 5º
• Plan a cleaning register. Simplify the tube connection to the heater by using additional
accessories such as telescopic tubes or cleaning Ts.
• The telescopic tubes allow detaching the chimney with no need of moving the appliance and
to easily inspect and carry out the maintenance.
• The cleaning Ts simplify the chimney cleaning.
• Seal all the chimney connector joints well with refractory filler.
• Should there be drilled holes in the connection adjusting ring of the appliance, secure the
chimney connector to the heater' s adjusting ring with appropriate screws. This secures the
adjustment and avoids vibration that may provoke the joints separating.
