5.7 Manufacturer Recommendation - Strainer
FIGURE 5-5 - Use of Strainer
Manufacturer Recommendation
A strainer filtering potable water before entering the boiler is highly recommended to prevent errors and lockouts. The stainer
prevents any sedimentation and debris from your water supply piping from entering the boiler. Debris carried from the water supply
will clog DHW water flow sensor resulting in error codes and causing boiler to lockout.
Locate the strainer as close to the boiler as possible and place on DHW (domestic hot water) inlet connection located at bottom of
the boiler.

5.8 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 at 43.5 psi /3.0 bar.
Pressure gauge - to indicate the system pressure to be maintained.
By-pass - Boiler incorporates an automatic by-pass, However, where all radiators are fitted with thermostatic radiator valves, an
external by-pass must be fitted.
