Commissioning Checks

IMPORTANT
Should the commissioning not be
carried out, then the manufacturers
2 year guarantee and any extended
warranty will become null and void.
It is therefore important that the
guarantee is returned to G.A.H.
Heating Products completed, in the
pre-paid envelope provided.
Building regulations require that the
Boiler is commissioned by an
OFTEC registered engineeer.
Note
For baffle positions see pages 39 & 40.
It is recommended that an O.F.T.E.C. trained and registered technician be used. It is the
responsibility of the installer to ensure that the Boiler is properly commissioned, see
BS5410 Part 1.
10-1.1 Oil Tank and Supply Line
The tank and supply pipe installation should comply with the details shown in Section 7
of this manual. Please check.
Check to see that a single supply pipe is used if the bottom of the tank is above the
Burner and that the two pipe suction/return is installed if the level of the oil in the tank
can fall below the level of the Burner.
Galvanised iron pipe should not be used, but black iron can, providing it has been
adequately protected against corrosion.
Copper pipe should be correctly sized relative to the length of the run and available head
or the required lift.
NO SOLDERED JOINTS. NO LEAKING JOINTS.
A remote sensing fire valve must be fitted.
Has a shut-off valve been fitted?
Disconnect the oil supply to the Burner and draw off 1 or 2 gallons of oil. Check for
impurities and repeat if necessary.
IMPORTANT
Check that there is no water in the oil filter before leaving the site.
Do not run Burner if impurities are found. This will damage the Burner
pump.
10-1.2 Two Pipe Oil Supply System
Check that a non-return valve is fitted in the suction line, refer to fig. 7-3d, page 30.
The return pipe should have an anti-syphon cut made just inside the top of the oil tank.
This pipe must then continue to within 50mm of the bottom of the tank, preferably not
near the sludge end.
10-1.3 The Boiler
Check that an imperforate hearth is used.
IMPORTANT
Check all baffles are in place, see pages 39 & 40.
Check that the system is full of water and whether a corrosion inhibitor and antifreeze has
been added.
Check all seals to access covers, doors and flue connections.
Check that phial capillary tubes are not trapped behind access covers.
10-1.4 The Burner
Check that the Burner pump is correctly set for 1 or 2 pipe oil supply. See page 48 of
this manual.
Check that the correct nozzle is fitted with the correct pump pressure for the output
required, see pages 45 & 46.
Check available air to the Boiler room for combustion and ventilation, see pages 31 &
34.
