Commissioning - Trianco EuroTrader 50/90 User, Installation, Commissioning & Servicing Instructions

5. COMMISSIONING

It is the responsibility of the installer to ensure the boiler
is properly commissioned, failure to do so will make the
boiler's guarantee and any extended warranty null and
void.
Although all burners are factory tested before
despatch, they will usually need further air adjust-
ment to achieve the readings indicated in 'Burner
detail leaflet' because of site variations in flue
draught and back pressure.
Procedure
1. Switch off electrical supply to the boiler.
2. Ensure boiler is full of water and all valves are open.
3. Remove flue-cover and check that flue-baffles are
correctly positioned (See Fig 12 for baffle arrangement).
4. Disconnect oil hose from burner, open shut-off valve
and run off a quantity of oil into a container to check
for a clean air free supply then reconnect hose. (This
applies to single pipe gravity system only).
5. Check that the time-switch (if fitted) is in the ON
position and room and boiler thermostats are calling
for heat.
6. Switch on electrical supply and the burner should
start.
Note: The burner may lock-out on first firing due to
air in the pump, if this happens, wait about a minute
before pressing reset button to restart burner. If a
further lock-out occurs, the air should be bled from
the pump pressure gauge connection.
7. Start and stop the burner two or three times until
the flame cuts off sharply - this indicates any
remaining air has been dispersed.
8. Allow the burner to run for about 15 minutes, then
take a CO reading through the sampling hole in
2
flue-cover. Compare the reading with that given
under 'Burner Settings' and adjust the air setting if
necessary to achieve the required CO
check the smoke and flue gas temperature.
Handing Over
After completing the boiler installation, the installer
should make a thorough check of the system to ensure it
is completely satisfactory and demonstrate to the user
the operation of the boiler and any system controls.
All instructions should be handed to the user for retention
and advice regarding the need for annual servicing.
Air Adjustment
The air damper is factory set at a nominal position to
suit typical conventional flue conditions. However
because of variations in flue draught it will usually be
necessary to slightly adjust the air damper in order to
achieve the CO2 level indicated under 'Burner Setting'.
N.B. When used with a Trianco Balanced Flue it will be
necessary to increase the air setting by 2 to 3 divisions
in order to obtain the correct CO2 level with zero smoke
reading.
The adjustment can be carried out by removing the end
cover from the burner and using a 4mm Allen Key rotate
screw 16 - clockwise to increase air lowering the CO2
and anticlockwise to raise CO2.
The air should be reduced until there is just a trace of
smoke (measured with a smoke pump) then opened
slightly to achieve a zero smoke reading. This provides
the optimum setting.
