4.5 Gas connection
!
DANGER
Danger of explosion due to leaking gas con-
nection.
• Install a gas counter and gas pressure reg-
ulator in the gas supply line.
• Following installation of the boiler, check
the gas connection for leaks.
For gas connection, see chapter 3.3, Fig. 14.
• Route gas connection straight to the rear!
4.6 Hydraulic connection
According to EN 12828:2003 the following safety-techni-
cal equipment is integrated into the boiler:
• Minimum pressure limiter DBmin
• Safety maximum pressure limiter DBmax
• Water pressure measuring device DBmax + 50%
• Temperature regulator
• Temperature measurement device TBmax + 20%
• Safety temperature limiter
Make sure the return is connected correctly so
as to achieve optimum efficiency.
To prevent noise emissions, connect the flow
and return pipes to the heating circuit with
flexible compensators.
Low-temperature return
(e.g. underfloor heating)
High-temperature return
(e.g. fan group or calorifier)
