5. SYSTEM CONSIDERATIONS
1. It is most important that the f low ra te sho wn in Table 4
corresponding
to the heating output that has b een selected
is achiev ed and a suitable by·pass must be included as
describ
ed in Section 9.
2. For circu it design purposes the pressure drop across the
appliance should be obtained
ft om Tab le 4 us i ng the
press
ur e drop cortespondingtotheheatiflg ovtput chosen.
there is no need
to take into account the higher boiler output
used for
domestic hot wate r.
3.
When a dema nd is made fo r central heating the boiler
ou
tp ut is modulated automatically from 8.8 kW to 19 k W
(30- 64 .800 B tu / h) in or der to give predominantly st ab le
ro om temperatu res .
4 _ When a demand is made
fo r domestic hotwa ter theboiler
outpu t is mod ulated au toma ticallv hom 8. 8 to 24 .0 kW
130-82,000 Btu/hi in order to give predominantly stable
ho t water temperatures.
5. The unit heats
the domestic hot watet instantaneously and
for the time that domestic hot wa ter is being dr a wn off the
central he
at ing system is temp orarily i nt errupted. When
hot wate r on ly is selected the ur~ i t will be completely cold
and a
few seco nd s w ill elapse while the heat exchangers
pre-h
eat before hot water is o bt ained.
6.
Th e appliance includes a cir cu l at i ng pump and no other is
required
7. Where room an d fr os t th er mostats are to be used they mus t
be suitable

nt air vents are required in the cupboard or
compart men t, one at high level. and one at l ow level,
eitherd i r4;!ct to outs i de ai r or to a room. Both high and l ow
