INSTALLATION<br />
<strong>30</strong> PRESSURE RELIEF VALVE (PRV) OUTLET - (SAFETY VALVE DRAIN)<br />
The PRV outlet is located at the rear RHS of the boiler service <strong>co</strong>nnection area.<br />
Connection of additional pipewok to the PRV outlet should be made prior to <strong>co</strong>nnection of CH, DHW and gas <strong>co</strong>nnections<br />
for ease of access.<br />
The discharge pipe should be positioned so that the discharge of water or steam cannot create a hazard to the occupants<br />
of the premises or damage the electrical <strong>co</strong>mponents and wiring.<br />
31 WATER AND GAS CONNECTIONS<br />
Included in the hardware pack provided with the boiler are all the necessary isolation valves, seals and pipework to <strong>co</strong>nnect<br />
the CH, DHW and gas <strong>co</strong>nnections (refer to Frame 9). Components are also provided for an integral filling loop. Each<br />
<strong>co</strong>nnection is individually bagged with the <strong>co</strong>rrect seals and pipework, and should only be opened when required.<br />
1. Pre-assemble the filling loop between the CH return<br />
and DHW inlet isolation valves as shown in the photo.<br />
2. Attach this assembly to the bottom of the boiler using<br />
the sealing washers provided. The <strong>co</strong>pper tail pipes<br />
may now be <strong>co</strong>nnected to the valve outlets.<br />
3. Connect the gas service <strong>co</strong>ck using the washer<br />
provided. The <strong>co</strong>pper tail pipe may now be fitted.<br />
4. Connect the DHW outlet <strong>co</strong>nnection<br />
5. Connect the CH flow isolation valve using the washer<br />
provided. The <strong>co</strong>pper tail pipe may now be fitted.<br />

WATER CONNECTIONS - CH<br />
Notes.<br />
For heating loads in excess of 60,000 Btu/h use 28mm x<br />
22mm <strong>co</strong>nnectors to <strong>co</strong>nnect the boiler flow and return pipes<br />
to 28mm system pipework.<br />
Do not subject any of the isolating valves to heat as the seals<br />
may be damaged.<br />
WATER CONNECTIONS - DHW<br />
Note. The DHW inlet isolating valve in<strong>co</strong>rporates a flow<br />
regulator and a CH filling loop <strong>co</strong>nnection.<br />

GAS CONNECTION<br />
IMPORTANT. The gas service <strong>co</strong>ck is sealed with a nonmetallic<br />
blue fibre washer so must not be overheated when<br />
making capillary <strong>co</strong>nnections.<br />
Refer to Frame 2 for details of the position of the gas <strong>co</strong>nnection.<br />
N.B. The principle of the 1:1 gas valve ensures that the<br />
<strong>Esprit</strong> <strong>HE</strong> range is able to deliver it’s full output at inlet<br />
pressures down to 14mb. However if dynamic pressures<br />
below 20mb are experienced ensure this is adequate for<br />
ALL other gas appliances in the property.<br />
A boiler gas supply pipe length of 20m and not less than<br />
15mm O.D. can be <strong>co</strong>nnected to the boiler via the gas<br />
service <strong>co</strong>ck union.<br />
