1.4 MODEL SELECTION GUIDE
General selection criterion is shown in table 1.1.
However before selecting the model, the space
heating and hot water requirements of the
dwelling are correctly assessed. If the appliance
is to installed in a cupboard, then the minimum
dimensions and clearances specified in section
2.1 (figure 2.1 and table 2.1) must be observed.
1.5 GAS SUPPLY
(a) The Local Gas Supplier should be consulted
at the installation planning stage in order to
establish the availability of an adequate supply
of gas.
(b) An existing service pipe MUST NOT be
used without prior consultations with the gas
supplier.
(c) A gas meter can only be connected by the Local Gas Supplier or by his Contractor.
(d) An existing meter should be of sufficient size to carryout the maximum boiler input plus the demand of any other installed gas
appliance, (BS 6891:1988). See section Technical Data (Table 3) for the gas required for each specific model.
(e) A minimum of 22mm diameter pipe work must be used up to at least 500mm from the appliance gas cock.
(f) The governor at the gas meter must give a constant outlet pressure of 20mbar when the appliance is running.
(g) The gas supply line must be purged. WARNING: before purging open all doors and windows and also extinguish any cigarettes,
pipes and any other naked lights.
(h) The complete gas installation must be tested.
1.6 ELECTRICITY SUPPLY
(a) The mains supply required is 230V~, 50Hz, 45A because all GulfStream
A-CLASS models have a 9kW electric backup boiler. However
the gas boiler/control and electric boiler circuits are internally fused separately. Minimum external fuse rating and the mains supply
cable rating are given in “Electrical Wiring” section of this manual. All fuses must be ASTA approved to BS 1362. This appliance MUST BE
EARTHED.
(b) All external wiring to the boiler must be in accordance with the latest I.E.E. Wiring Regulation, and any local regulations which may
apply.
(c) There must be only one common isolator for the boiler and its control system, and it must provide complete electrical isolation via
a fused double pole isolator with a contact separation of at least 3mm in both poles.
(d) In the event of an electrical fault after installation of the appliance, preliminary electrical checks must be carried out i.e. Earth
Continuity, Short Circuit, Polarity, and Resistance to Earth.
1.7 APPLIANCE LOCATION
(a) GulfStream
A-CLASS is room sealed and therefore can be located in any room/compartment in a domestic property. Although the
appliance is essentially quiet, it does incorporate a fan and pumps. Therefore the chosen position should bear this in mind and not be
the one which is particularly sensitive to noise.
(b) The boiler is NOT suitable for external installation. The position selected for installation should be within the building, unless
otherwise protected by a suitable enclosure, and MUST allow adequate space for installation, servicing, and operation of the appliance
and for air circulation around it.
(c) The installation position MUST allow for the flue and air inlet system to be fitted in correct position as per installation manual(s).
(d) The boiler must be installed on a flat surface, which is capable of supporting the weight of the appliance and any other ancillary
equipment.
