Do not use the boiler if any part has been under water. Call a qualified service technician to inspect the
boiler and replace any part of the control system, which has been under water.
Never operate this appliance with any safety switches altered or disabled. Never attempt to modify this
appliance in any fashion.
Boiler
At the beginning of each heating season, the boiler flue passages and the burner should be checked for
cleanliness and if necessary they should be cleaned. The following procedure is required for inspection and
cleaning the boiler flue passages.
1. Turn off all electrical power to the boiler before inspecting and cleaning.
2. Disconnect the Molex plug at burner.
3. Remove the boiler front jacket panel by lifting vertically.
4. Open the swing door following previously described procedure.
5. If required remove any scale and soot deposits with a flexible flue brush. Vacuum all deposits from
flue passages and chamber area. Be careful not to damage the door insulation.
6. Close swing door following previously described procedure. Check to ensure a proper seal between
the door and the boiler has been made.
7. Eliminate any combustion gas leaks by replacing worn seals and gaskets.
8. Install jacket front panel.
9. Connect Molex plug for burner power.
10. Protect the heating system against freezing dangers with anti-freezes as required. Avoid
intercommunications between domestic hot water and heating water since these antifreezes are toxic
substances.
11. Check the piping system for leaks and repair as required. This will prevent water turnover with
consequent risk of scale formation and corrosion in the boiler room.
12. Check for proper operation of the relief valve following the manufactures recommended proceedure.
Corrosion can build up rapidly at the valve seat and prevent its functioning as a safety device.
Burner
Refer to the burner installation and operation manual provided for maintenance procedures.
Vent System
Chimney Vent- Inspect the chimney and vent system to ensure its cleanliness and condition. Remove any
accumulation that may have occurred at the clean out door. Inspect and clean all vent piping and vent
components replacing as necessary.
Direct Vent – Inspect and clean vent and air intake piping. Replace and reseal joints as required. Inspect
vent hood air inlet and discharge for obstruction.
Domestic Hot Water Storage Tank
1. Sizing of the hot water tank must be matched with the hot water usage.
2. Piping must be in accordance with the appropriate codes and the Solaia manual.
3. Follow the installation instructions of the hot water domestic tank you have chosen to install with the
Solaia boiler.
Danger… Water temperature exceeding 125 F will cause severe burns instantly or death by scalding.
An automatic mixing valve must be installed on the outlet of the domestic waterside of the tank.
Installation must comply with the valve manufacture’s recommendations, and instructions.
Pipe in accordance with the installation manual.
Due to varying water conditions, an adjustable flow restrictor may be required in the coldwater
inlet of the tank.
