first-year inspection of the boiler. This should include the following
in addition to routine annual start-up procedures
a. The integrity of the flue system and the flue seals;
b. The integrity of the boiler combustion circuit and the relevant
seals;
c. The operational (working) gas inlet pressure at maximum rate,
as described on pages 46 and 66 of the boiler manual;
d. The gas rate, as described on page 46 of the boiler manual;
e. The combustion performance, as described on page 65 and 66,
of the boiler manual for combustion check.
f. Competence to carry out the check of combustion performance
g. The person carrying out a combustion measurement should
have been assessed as competent in the use of a flue gas analyzer
and the interpretation of the results;
Periodical check
h. To keep the unit working properly over time, it is necessary to have
qualified personnel make an annual check that includes the follow-
ing tests:
i.
The control and safety devices (gas valve, flow meter, thermostats,
etc.) must function correctly.
j.
The flue pipes must be fully intact, secure and clear.
k. The airtight chamber must be sealed.
l.
The air-flue terminal and ducts must be free of obstructions and leaks.
m. The condensate evacuation system must be efficient with no leakage
or obstructions and drain condensate without backing up.
n. The burner and exchanger must be clean and free of scale. When
cleaning, do not use chemical products or wire brushes.
o. The electrode must be free of scale and properly positioned.
p. The gas and water systems must be leak free.
q. The water pressure in the heating system must be about 18 pounds;
fill the boiler to that pressure or the system design pressure.
r.
The circulation pump must not be blocked.
s.
The expansion tank must be filled.
t.
The gas flow and pressure must correspond to that given in the
respective tables.
2. Determine any follow-up maintenance and service needs based on
the condition of the heat exchanger and condensate lines.
a. If the heat exchanger shows substantial fouling, or if condensate lines
show accumulation of sediment, schedule a follow-up service call
to perform the first-year inspection again, sooner than the normal
twelve months between.
b. Heavy fouling of the exchanger or condensate lines indicates possible
combustion air contamination. Inspect the air intake area carefully,
and remove possible contaminants. See page 4, for products to avoid.
You must eliminate causes of corrosion and contamina-
tion to ensure reliable operation of the boiler and system.
