UNVENTED SYSTEMS -DRSE HEATERS
With the exception of the relief valve
position and the size of the Nabic relief
valve (see Table 1 DRSE (UV) Water
Heaters) the Unvented Kit and its
application on DRSE heaters is identical to
the DRL (UV) models. See Installation,
Commissioning and Maintenance Manual
Appendix 3.
On DRSE (UV) heaters the 3/4" BSP Nabic
temperature and pressure relief valve is
fitted in the 1" BSP socket (6), ref Figure 1,
this normally being the recirculation
connection for the heater .
If recirculation is required on the hot water
distribution system, the circulation return
should be teed into the appliance cold feed
generally as shown in Figure 1.
