6.8 Central Heating System
Boiler is designed for use in a sealed central heating system.
Design the system to operate with flow temperatures of up to
176°F (80° C), take pump head, expansion tank size, mean
radiator temperature, etc. into account.
Boiler is supplied with the following components:
Pressure relief valve
- 30.0 psi (2.1 bar). Boiler internal
pressure switch will shut boiler off below 7.25 psi (.5 bar)
and above 43.5 psi (3.0 bar).
Pressure gauge
- to indicate the system pressure to be
maintained.
By-pass (75, 100 & 125)
- Boiler incorporates an
automatic by-pass, However, where all radiators are fitted
with thermostatic radiator valves, an external by-pass must
be fitted.
6.9 Frost Protection Mode
Frost protection mode is integrated into the appliance when
electricity is connected to the boiler, regardless if power is "on"
or "off".
If boiler water temperature falls below 41°F / 5° C boiler will
fire on its minimum setting until flow temperature of 86°F /
30° C is reached.
6.10 Pump Protection
Pump and 3 way valve protection will automatically operate for
1 minute in every 24 hours of inactivity to prevent seizing.
