3.2 PLUMBING - OPEN OUTLET
1. When installed as an Open Outlet water heater the outlet acts as a vent
and must not be connected to any form of tap or fitting not recommended
by Heatrae Sadia.
2. Only one outlet can be served. The fittings supplied include an inlet Tap,
300mm Open Outlet Spout, a 15mm straight Push Fit connector and a
15mm Push Fit cap. The heater should be sited so that the spout can
discharge into a suitable sink or basin.
3. Streamline option packs K, Q, Y, J, M, W, R, P, X, or S/T can be used in
place of the spout to provide a single tap outlet. Flow rates will be at a
reduced rate. Note: item 3.2.7
4. The cold water supply may be taken from the cold water mains or
from a cold water feed cistern complying with Water Byelaw 30 with a
minimum recomended pressure of 0.4 bar (4 metres head). A drain cock
should be incorporated in the supply to facilitate draining the heater for
maintenance.
5. The inlet tap should be fitted to the INLET pipe of the heater.
The inlet
must not be connected directly to the cold water mains supply.
The
Outlet Spout should be fitted to the OUTLET pipe using the 15mm
straight push fit connector supplied in the fittings kit.
6. The 15mm Push Fit Cap, with tamperproof collet, must be fitted to the
Vent Pipe on the top of the heater.
7. In an Open Outlet installation it is normal for the spout to drip during
heating. This is due to expansion of water as it is heated within the unit, it
does not indicate a fault. DO NOT attempt to stop this dripping by over-
tightening the inlet tap as damage to the sealing washers or internal
operating mechanism will occur.
