Fasten in place between the 10mm nuts provided on the casting. Insert the two anti-short bushings into the holes on the right hand side in the upper brackets. 4. Install right side jacket panel to the upper and lower brackets with sheet metal screws provided. 5. Install the .” electrical connector required for the Carlin control or the Honeywell L7248A1000 through the hole in the front part of the right side jacket panel and tighten in place with the locknut provided. Install the Heyco bushing in the hole when using the Honeywell L7248C1022. 6. Install the left side jacket panel, to the upper and lower brackets with the sheet metal screws provided. 7. Install the Honeywell L7248A1000 aquastat onto the box connector using the clamping screw or screw the Honeywell L7248C1022 directly to the right side jacket panel. 8. Install the sensor wires. a) Honeywell L7248A1000 – Run the sensor wires through the hole in the aquastat and out the box connector. Run the sensor wires through the holes in the upper brackets and insert into immersion well. Fasten the wires into the well using the wire clamp provided. Snap sensor wires into control. b) Honeywell L7248C1022 – Run the sensor wires through the Heyco bushing. Run the sensor wires through the holes in the upper brackets and insert into immersion well. Fasten the wires into the well using the wire clamp provided. Remove one of the unused knockouts in the bottom of the aquastat. Insert sensor wire through the knockout securing with grommet supplied. Snap sensor wires into control. c) Carlin Control – Install the box provided with the control onto the box connector. Run the sensor wires through the hole in the aquastat and out the box connector. Run the sensor wires through the holes in the upper brackets and insert into immersion well. Fasten the wires into the well. Insert sensor wires into control. 9. Install the top panel by sliding it in from the front catching the top panel’s lower edge under the sides upper edges. Slide back till the top drops over the back edge, fasten with the sheet metal screws provided. 10. Install the back panel with the small notches facing up and fasten with sheet metal screws provided. 11. Install the jacket front panel by lining up the (4) mounting screws on the front of the two sides with the keyhole slots on the front panel and lower in to place. 12. Transfer the boiler serial number located on the left front leg onto the rating label on the jacket front panel in the upper left corner.

Pipes that are connected to boiler fittings must be supported and placed so that they do not create stresses on the boiler fittings themselves. BY PASS PIPING IS REQUIRED ON ALL LOW MASS BOILERS WHERE THE BOILER RETURN WATER TEMPERATURE COULD OPERATE BELOW 130.F FOR EXTENDED PERIODS OF TIME. The Solaia boiler is a highly efficient low mass boiler in which care must be taken to ensure that high volumes of low temperature water are not introduced into the boiler. Operating at return water temperatures below 130.F for extended periods of time will allow for the accumulation of condensation, scale and increased soot formation in the boiler. Corrosion and eventual heat exchanger failure will result. A thermostatic bypass valve is highly recommended on high water volume standing cast iron systems. A thermostatic bypass valve will consistently ensure that return temperatures to the boiler exceed 130oF at all times. See Figure 1 for Thermostatic Bypass valve piping. Instead of using a thermostatic bypass, bypass piping may be accomplished by placing a 3/4” bypass line with a throttling valve for regulation between the supply piping and return piping. Boiler return water temperatures must exceed 130.F with the bypass properly adjusted. Low water cut off Hot water boilers installed above radiation level must be provided with a low water cut off device at time of the boiler installation. Relief Valves Relief valves are to be properly piped in to conform to code standards. Discharge piping from the relief valve must be piped to a drain or must terminate 6” above the floor to eliminate damage to the structure or personal injury. It must not be piped to a point where freezing may occur. Expansion Tanks The expansion tank must be properly sized to the system requirements. An undersized expansion tank will cause system water to be lost through the relief valve and make up water to be introduced through the fill valve. Continual introduction of fresh water will cause boiler failure. VENTING Failure to follow all instructions can result in flue gas spilla...
