7.8 Heating power output adjustment
To comply with Building regulations, the heating output must
be set according to the requirements of the installed heating
system.
This is done by adjustment of "parameter 15" (tS 1.5).
Calculate the heating requirements of the heating system in
kW. Determine what that value is, as a % of the nominal heat
output of the boiler, see table "Technical features" page 18.
Access the parameters as shown in "Parameter setting and
display" page 37, and adjust the parameter 15 (tS 1.5) to that
% value
Example:
– Heating system with 8 radiators, average 1.5 kW per radia-
tor total heat
– Requirement 12 kW (8 x 1.5)
–
Maximum nominal heat output of boiler = 23.6 kW
– Parameter 15 (tS 1.5) = 12/23.6 = 50.8%. Set tS 1.5 to 51%.

CAUTION
As a condition of the warranty and to ensure correct
operation and efficiency, it is important that the boil-
er is serviced every 12 months, within 30 days of the
anniversary of the installation date ensure the re-
quired information is recorded in the Gas Boiler Sys-
tem Service Interval Record (page 47) (Benchmark).
