draught is too strong
Air distribution lifting cable is not
lubricated.
Package plastic waste and card-board
boxes are burnt in the boiler
Lower than 60ºC boiler temperature is
maintained

7.1. HEAT HAZARDS

Upon touch of hot boiler elements, it is possible to get burnt. The surface of the boiler which can be
heated up to 40º C temperature and other parts according to technical characteristics are insulated with
heat insulation but there are such parts like door handles and doors which are heated more and are
hazardous to humans. Such places are marked with an international danger mark. Hot water pipes of the
heating system after hydraulic testing must be insulated with heat insulation. Pressure valve escape pipe
must be lead up to sewerage or vessel by leaving a 10 cm gap for monitoring and insulated with heat
insulation or marked with a heat hazard mark.
Pulsing is heard in the boiler, sometimes
air valve is jumping. The boiler operates
very uneconomically, condensate leaks, it
lacks capacity. Turn the valve regulating lever up in
the chimney flue and fix up so that the draught shall
easily open the air injection valve. If you purchased
the boiler without a chimney flue connector, it is
sufficient to cut a U form section in the ledger and
gradually unbent the formed "tongue" till the boiler
operation becomes stable.
Air distributor is lifted heavily, cable gets
worn. Must be lubricated with lubricant
WD – 40 or grease.
If packing cartons retard combustion,
then to combust plastic construction or
packing waste is dangerous since generated
gas does not combust evenly, their excess
accumulates the explosion of which in the
chimney or boiler dismantles chimney flue
The boiler and chimney flue are clogged
due to condensate.
