4.2   ELECTRICAL WIRING
The standard models are supplied with factory fitted single channel heating and hot 
water programmer. Therefore only a room thermostat is required to be supplied and 
wired to the appliannce.

However, other system controls e.g. 2-channel remote programmer, programmable 
room thermostat can be connected to the appliance and for this, the appliance model 
with no clock option should be ordered.

4.2.1   General
(a)  WARNING:  This  appliance  MUST  BE 

EARTHED. 

(b)  The wiring must comply with the current 

I.E.E Requirements for Electrical Installations 
(BS 7671) and the requirements of the local 
electricity utilities.

(c)  It  is  the  responsibility  of  the  competent 

electrical installer to use the details in this 
manual with the latest British Standards. 

(d)  The  appliance  has  integral  9kW  electric 

backup  boiler  and  therefore  the  supply 
must  be  230V~,  50Hz  rated  at  45A  as 
discussed below in table 4.4.

(e)  All electrical wiring to the appliance should 

be  secured  to  prevent  the  wires/cables 
touching  any  hot  surfaces  inside  and 
outside the appliance case.

(f)  The  appliance  is  supplied  with  2m  long, 

10mm

2

 (twin + E) flexible cable and it must 

be connected to a local (not more than 2m 
away from the appliance) 45A double pole 
isolator having a contact separation of at 
least 3mm in both poles as shown in figure 
4.5.

4.2.2      Connecting  Power  Supply  to  the 

Appliance

(a)  Ensure that the electricity supply is switched 

off. 

(b)  The  appliance  is  supplied  with  2m  long 

10mm

2

  (twin  +  E)  flex.  Uncoil  this  and 

connect it to the local fixed isolator (figures 
1.1. 1.2 and 4.5).

(c)  DO NOT SWITCH ON the electricity supply 

to the appliance at this stage.

4.2.3   Room Thermostat (Standard Models)

 

The  standard  GulfStream  models  are 
supplied with factory fitted and wired single 
channel  programmer  for  controlling  the 
hot  water  and  space  heating  on-off  time 
periods. This appliance is only suitable for 
connecting  230V,  50Hz  i.e.  mains  voltage 
room thermostats.

(a)  Remove link L1 from terminals labelled ‘L-R’ 

and ‘SL-h2’ (see figures 4.4A).

(b)  Wire the room thermostat to the appliance 

terminals as shown in figure 4.6
