See
BS 5440 states a suitable guard should be provided whenever the
appliance terminal is fitted less than 2 m above ground, above a
balcony or flat roof.

6.4.4 Power compensation for increasing the permissible flue
gas piping lengths
The maximum flue gas piping lengths arise from the requirement that the
power reduction by the flue gas counter-pressure is no more than 5%. For
systems in which the "Max. total length of the flue gas piping" that is
specified in the "Permissible flue gas piping lengths" table (see reference
below) is not sufficient, the boiler's fan speed can be increased. This
means that the power reduction is compensated for and larger flue gas
piping lengths can be used (see table "Permissible flue gas piping
lengths", "Max. total length of the flue gas pipe following power
compensation").
Prog. no. 9626 and 9627 must be changed for this power compensation.
You are in the "Burner control" menu. The changed values for operating
with natural gas or LPG can be found in the tables below.

Standards and regulations
Besides the general technical rules, the following should be particularly
observed:
Regulations of the accompanying certificate of approval
Planning laws and building regulation.
Contaminated chimneys
Combustion of solid and liquid fuels generates deposits and pollution in
the respective flue gas tract. Soot contaminated with sulphur and
halogenated hydrocarbons sticks to the inside walls. Such flue gas tracts
are not suitable for the combustion air supply of heat generators without
pretreatment. Contaminated combustion air is one of the main causes of
