The flow and return pipework can exit the boiler
enclosure either through the openings provided in both
sides (under the movable cover plates) and through the
wall when installed against the building, or down and
through the openings provided in the base of the
enclosure for 'free standing' installations.
Fit drain cocks in the central heating and domestic hot
water systems to allow the complete system to be fully
drained.
Ensure the flow pipe is vented as its the highest point
of the boiler.
To avoid the danger of dirt and foreign matter entering
the boiler the complete heating system should be
thoroughly flushed out - before the boiler is connected
and then again after the system has been heated and is
still hot. This is especially important where the boiler
is used on an old system.
For optimum performance after installation, this boiler and its
associated central heating system must be flushed in accordance
with the guidelines given in BS 7593:1992 'Treatment of water
in domestic hot water central heating systems'.
This must involve the use of a proprietary cleaner,
such as BetzDearborn's Sentinel X300 or X400, or
Fernox Restorer. Full instructions are supplied with
the products, but for immediate information, please
contact BetzDearborn on 0151 4209563 or Fernox on
0179 9550811.
For Long term protection against corrosion and scale,
after flushing, it is recommended that an inhibitor such as
Betzdearborn's Sentinel X100 or Fernox MB-1 is dosed
in accordance with the guidelines given in BS 7593:1992.
Failure to implement the guidelines will invalidate the
warranty.
