5.7 Manufacturer Recommendation - Strainer
FIGURE 5-5 - Use of Strainer
Manufacturer Recommendation
Manufacturer strongly recommends the use of a strainer filtering potable water before entering the boiler. The strainer 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, potentially resulting in significant operation issues.
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.
