The tundish must be positioned so that it is visible to the occupant and is away from
electrical devices.

Expansion relief/PRV combination valve
Temperature and Pressure Relief Valve
Control thermostat
Energy cut-out thermostat
Energy cut-out motorised valve (indirects only)
Tundish
Immersion heater
(Note: Two immersion heaters are supplied with the direct Xstream)
In any situation where the volume of heated pipework (eg. secondary circulation pipes
or manifold pipework for multiple units) exceeds 10 litres, then an additional expansion
vessel must be fitted to accommodate the extra expansion volume.
HANDLING BEFORE INSTALLATION
Xstream must be handled with care and stored the correct way up in a dry place.
Any manual handling/lifting operations will need to comply with the requirements of
the Manual Handling Operations Regulations issued by the H.S.E.
The appliance can be moved using a sack truck on the rear face although care should
be taken and the route should be even.
In apartment buildings containing a number of storeys we would recommend that
the appliances are moved vertically in a mechanical lift.
If it is proposed to use a crane expert advice should be obtained regarding the need
for slings, lifting beams etc.
A specific manual handling assessment is shown in Appendix B at the rear of this
manual.
MAINTENANCE
Modifications should not be made to this product.
Replacement parts, including immersion heaters, should be purchased from Gledhill
Building Products, or agents approved by them.
Unvented hot water storage vessels need regular routine checks, and these are detailed
below. It is for this reason that this manual must always be left with the Xstream.
It is recommended that these checks be
carried out at the time of boiler maintenance
by a qualified installer:
1. Manually open the relief valves in turn, and
check that water is discharged from the
valves and runs freely through the tundish
and out at the discharge point. Ensure that
the valves re-seat satisfactorily.
2. Turn the mains water off and remove and
clean the strainer element in the Pressure
Reducing Valve.
3. Check the charge pressure in the
expansion vessel and repressurise if
required
4. Re-fill the system and ensure that all relief
valves have re-seated.
