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. -

(3) Though the unit is suitable for wall mount, only the rear face indicated as “Zero Clearance” may be mounted against combustible surfaces. (4) Units must be mounted straight as shown in Fig. 2 with the outlet at the top, and the inlet on the bottom. -
Page 7: Thermostat Connection
The pump is powered by the boiler through terminals PL and PN located on the 120 volt terminal block (lower right terminal block see Fig. 4). The pump starts when the thermostat terminals on the control board are closed, and stops when these terminals are opened. -
Page 8: Check List
Temperature Control Setting (Aquastat) The boiler has a temperature control knob know as an aquastat on the lower left corner of the control board. This sets the maximum temperature that the boiler will operate at. The internal control system monitors the water temperature in the tank and modulates the heating elements to maintain the water temperature. -
