Page 5: System Design
System Design For proper operation of the heating system, the boiler, the radiation system, and maximum heat loss of the building must be considered. The boiler selected should provide between 110% and 130% of the maximum design heat loss of the building. The radiation system should be designed to properly dissipate the heating capacity of the boiler at the radiation system design temperature. -

(4) Units must be mounted straight as shown in Fig. 2 with the outlet at the top, and the inlet on the bottom. See “Up Arrow” on label on side of boiler. (5) The circulation pump should be connected to the outlet side of the boiler (see Fig. 3). Mechanical Installation (1) Refer to Fig. - Page 7 If desired, the pump may be operated continuously during the heating season. Should you decide to wire the pump in this manner, it should be wired to the same supply circuit as the boiler to prevent the pump from being turned o while the boiler is still powered. Thermostat Connection Only connect the thermostat a er all The thermostat connection is 24 volt AC.
