MAINTENANCE
PAGE 15
To ensure reliable operation of the fuel-burning heater, perform the following maintenance
inspections at least once per year, at the end of the heating season, or well ahead of the start of
the season.
General servicing:
 Replacement of the fuel filter.
 Replacement of the nozzle.
 Inspection of motor carbon brushes.
 Inspection of pipes and hoses for any leaks. It is particularly important that the heater’s fuel suc-
tion hose has absolutely no leaks. All fuel hoses should be replaced every 2 years. Use only hoses
sourced from STROCO, or hoses approved by STROCO. The heater’s warranty will be void if it is
fitted with hoses not approved by STROCO, or if there is no documentation of replacement of fuel
hoses with 2 year intervals.
 Inspection of the boiler and combustion pipe. Removal of any soot or incrustation from the boiler.
 Replacement of the combustion pipe if damaged.

Inspection of the combustion unit.
Electrodes, nozzle, and turbolator should be clean and undamaged.
Replacement of the nozzle and subsequent check that the nozzle is centred in the turbolator.
Checking of electrode setting as per page 24.
Improper combustion can lead to boiler or combustion pipe being blackened by soot.
The nozzle service life is limited. Do not attempt to clean or repair the nozzle, but replace it with a
new one.
Inspection of the photoelectric sensor for cracks; cleaning if necessary.
Inspection of the coupling between fan motor and fuel pump; replacement of the coupling if the
contact surfaces are worn.
When the combustion unit is fitted back on the boiler, adjust the fuel pressure to the correct value
and then adjust the air setting to comply with relevant combustion data.
 Inspection of all cables and electrical connections for possible damage or corrosion.

Outside the heating season, run the heater for at least 15 min. per week.
IMPORTANT!
 When using biofuel, the fuel pump must be replaced every 2 years.
 Fuel hoses must be replaced every 2 years regardless of fuel type. Fuel hoses must be replaced with
original STROCO fuel hoses, or approved hoses that meet the same minimum specifications.
 It is important that hoses, seals etc. be inspected for leaks continually. Leaky fuel lines present a
serious safety hazard. The warranty on the STROCO fuel-burning heater will be void in case of
deficient or improper servicing.
