Safety
For Your Safety (continued)
WARNING
Fire causes a risk of burns and explosion!
H Shut down the boiler
H Close fuel shut-off valves
H Use a tested fire extinguisher, class ABC.
WARNING
Incorrect ambient conditions can lead to damage to
the heating system and put safe operation at risk.
H Ensure ambient temperatures are higher than 32° F (0° C)
and lower than 104° F (40° C).
H Prevent the air from becoming contaminated by
halogenated hydrocarbons (e.g. as contained in paints
solvents or cleaning fluids) and excessive dust (e.g.
through grinding or polishing work).
Combustion air for the heating process, and ventilation
of the boiler room must be free of corrosive contaminants.
To that end, any boiler must be installed in an area that
has no chemical exposure.
The list to the right indicates the main, currently known
sources.
H Avoid continuously high levels of humidity (e.g. through
frequent drying of laundry).
H Never close existing ventilation openings.
If you notice fire coming from the appliance, call the fire
department immediately! Do not attempt to extinguish the
fire unless qualified to do so.
IMPORTANT
Components which are not tested with the heating system
may damage the heating system, or affect its functions.
Installation or replacement may only be carried out
by a qualified heating contractor.
