Instructions for installation and servicing ecoTEC
7.1.2 Maintenance
Before commencing any servicing or maintenance work,
carry out an initial inspection of the system as follows:
• Inspect the flue, pipework and electrical connections
for indications of damage or deterioration.
• Inspect the air supply and ventilation arrangements of
the installation.
• Check the heating and water system, in particular the
condition of radiator valves, evidence of leakage from
the heating system and dripping hot water taps.
7.1.3 Overview of the inspection and maintenance
tasks
No. Activity
Column 1
Inspection must
be carried out
once a year
Column 2
Maintenance
1 Check the air / gas flue system and ensure it is not blocked, damaged and is fitted correctly. x
2
Measure the gas rate during operation (see table 5.1 inside the chapter commissioning part I).
If the gas rate is lower than the minimum gas rate follow the maintenance instructions (column
2).
x
3
Check combustion by measuring CO and CO
2
values, compare to table 9.2. If the measurement
is outside the tolerances follow the maintenance instructions (column 2). If a flue gas analyser
is not available check the ignition and burner flame picture through the sight glass, if incom-
plete combustion is evident perform the maintanance instructions (column 2).
x
4 Isolate the appliance from the electrical mains supply, close the gas and water service valves. x
5
Visually inspect the general heat exchanger area for signs of corrosion, sooting or other forms
of damage. If damage is evident perform the tasks in the maintenance column 2.
x
6
Remove the burner module (as described in section 7.2.1) if maintenance schedule is required
from steps 2, 3 or 5 above. Clean the primary heat exchanger. Fit a new burner door seal kit
(observe the assembly instructions enclosed with the seal kit). Refit the burner module and
tighten the nuts.
x
7 Check all the appliances electrical connections and make adjustments if necessary. x x
8 Check / re-pressurise the expansion vessel as necessary. x x
9 Check the appliance generally, check for dirt / dust and clean if necessary. x x
10 Check and clean the condensate trap and flexible condensate hose. x x
11 Open the gas and water service valves, re-establish the electrical supply and turn on the boiler. x x
12
Perform a test operation of the appliance including the heating and hot water systems and
bleed the system if necessary.
x x
13
Re-pressurise the appliance / system up to between 1.0 - 2.0 bar (depending on the static height
of the system).
x x
14
Measure the gas rate during operation and ensure it is within the tolerances specified (see
table 5.1 inside the chapter commissioning part I).
x
15
Re-check the combustion by measuring the CO and CO
2
values, (compare to table 9.2). Ensure
that the measurement is within the tolerances. If a flue gas analyser is not available check the
ignition and burner flame picture visually through the sight glass. x
16 Check the boiler for leaks of any kind, rectify as necessary. x x
17 Complete the gas commissioning checklist (Benchmark). x x
Table 7.1 Inspection and maintenance steps
7.1.4 Functional check of boiler operation
• Carry out a functional check of the boiler operation as
previously detailed.
• Remove the appliance casing as detailed and operate
the boiler.
• Inspect the burner operation through the viewing win-
dow.
• Check that the flames are evenly covering the surface
of the burner.
• Inspect for signs of excessive flame lift or sooting.
