coloured green. Plastic tanks do not need to stand on piers, but should be supported across the entire base
area, ideally on 50mm thick garden slabs or a concrete base. As there is only one tapped outlet they are more
suited to single pipe feed as gravity supply or with a Boulter 3K Oil Loop Deaerator where suction lift is
required. (Part No. BS 03060)
4:8 OIL SUPPLY
The oil entry holes in the boiler casing are shown in the diagram in
supplied with the Boiler MUST NOT pass through these holes.
All joints in the Oil Lines must be oil tight and the Oil Line should be flushed clean before connecting to the
burner.
Note that no soldered joints are permissible in the oil line.
4:8.1 Oil Filter
An Oil Filter is supplied with the Boiler.
Connections are 1/4 BSP Female, see
It is essential for reliable operation that the Oil Filter is fitted in the Oil Pipe supplying Oil from the
Tank to the Burner. It should be fitted as close to the Boiler as practicable, but NOT inside the Boiler
casing.
It is a condition of the guarantees that the Filter is fitted correctly.
4:8.2 Fire Check Valve (Not Supplied)
A Remote acting FIRE VALVE* must be fitted in the suction line at the time of installation - see BS 5410: Part
1.
The valve must be fitted external to the Boiler, preferably at point where the Oil Pipe enters the building. The
sensor should be located above the Burner in the clip provided, see
The entry point for the Fire Valve Sensor should be through any of the 20mm ET knockouts located at the top
of the rear casing, or side panels.
To prevent damage to the capillary always pass the sensor through the blind grommet (supplied), it will be
necessary to cut across the diaphragm.
*Remote Acting Fire Valves are available from Boulter, through your merchant or installer e.g.
