2.7 MAIN STEAM VALVE
The main steam stop valve should be inserted in the steam line approximately 12in. (305 mm) from
the top of the boiler.
2.8 STEAM SAFETY VALVES
SafetyValvesarefactoryttedandpreset,theyMUSTNOTbeadjusted.Thedischargeoutlet
should be piped to a safe discharge point and the piping so arranged that any condensate trapped
in the pipework will drain away from the valve.
Note: It is recommended that the safety valve discharge pipework is installed to the requirements of BS806
clause 4.9.7.
(a) The lift pressure is indicated on the safety valve. (Do not adjust).
(b) Thesafetyvalvettedtotheboilerisdesignedtopreventtheboilerexceedingit'sdesign
pressure.
(c) Any system connected to the boiler not capable of accepting boiler pressure must be
protected by a separate safety valve set to the required pressure.
(d) Longradiusttingstobeusedwithaminimumof6diameterstothersttting.
2.9 WATER GAUGE SET (The design may vary from that illustrated)
Numbers may vary due to individual countries regulations.
Boilers are normally supplied with two complete water gauge sets. The water gauge blowdown
cock should be connected to the auxiliary blowdown line from the water column blowdown valve in
soft copper tubing. The connection to the gauge cock is 6mm (0.25in.).
2.10 OIL SUPPLY
The positioning of the oil storage tank will be dependent on site conditions and local regulations. The
burner fuel pump is of the bypass type requiring the installation of feed and return lines between the oil
storage tank and the boiler. These lines should be in tubing of a minimum bore of 10 mm.

To overcome suction problems at the fuel pump, all vertical lifts in the feed pipe should be made as
close to the boiler as possible. The burner fuel pump pressure is preset at the factory and should not
require adjustment.
2.11 ELECTRICAL REQUIREMENTS
An individual wiring diagram for the boiler is located on the inside cover of the control box.
Whenreferringtotheelectricalspecicationoftheboiler,thereferencenumberlocatedontherear
inside wall of the control box and the wiring diagram number should be quoted.
The audible alarms provided are mounted on the side of the control panel, if not audible they
should be repositioned where they can be heard by a person competent to take the appropriate
action should the alarm be activated.

The power ratings and requirements are given in Technical Data - Section 5.
WARNING
Factory tted safety valves are preset to protect the boiler only and
must not be used to protect any other items not capable of
accepting boiler pressure.
