Installation & Setup
The Alpha Evoke 28 installation requires a room, 1.5 m clearance, and a 10 kW gas supply. Mount the unit on a stable wall, connect the condensate drain, and link the gas line with a pressure regulator. Follow the manual’s wiring diagram for safety.!
Site Preparation Requirements
Before installing the Alpha Evoke 28, ensure the installation area meets the manufacturer’s specifications. The boiler must be mounted on a solid, level wall with a minimum 1.5 m clearance on all sides to allow adequate airflow and maintenance access. The room should be sealed to prevent heat loss, with a minimum 10 kW gas supply and a pressure regulator that maintains 0.5 bar. A condensate drain must be installed, connected to a suitable drainage system, and the condensate pipe should be insulated to avoid condensation on the wall. Electrical connections require a dedicated 32 A circuit, with a residual‑current device (RCD) rated 30 mA for safety. The area must have adequate ventilation to meet local building codes, and the boiler should be positioned to avoid direct exposure to moisture or corrosive environments. Finally, verify that the gas and electrical connections comply with local regulations, and perform a pressure test before commissioning to ensure leak‑free operation. All installations should be verified by a qualified technician, and the boiler must be registered with the local authority before first use. During commissioning, monitor the boiler’s pressure and temperature gauges to confirm that the system reaches the target operating range within the specified tolerance limits. If any deviation is detected, shut down the unit, check the condensate line, and verify gas pressure remains within the manufacturer’s range.
Installation Procedure
Begin by verifying the wall mounting surface is level and can support the boiler’s weight. Attach the mounting brackets to the wall using the supplied screws and anchors, ensuring a minimum 30 mm clearance from the nearest wall or obstruction. Lift the boiler into position, align the mounting holes with the brackets, and secure it with the provided bolts, torqueing to the specified value. Route the gas pipe from the main line to the boiler’s inlet, set the pressure regulator to 0.5 bar, tighten all fittings, and perform a pressure test to confirm no leaks. Attach the 32 A dedicated circuit to the boiler’s power terminals, install the RCD, verify polarity, and secure the cable with ties. Connect the condensate drain, ensuring a 5 % downward slope toward the drainage system and insulate the pipe to prevent condensation. Mount the control panel, connect the thermostat wiring, and perform a full system check. Power on the boiler, set the desired temperature, and observe the pressure and temperature gauges to confirm proper operation. Document all steps in the installation log and schedule the first commissioning test with a qualified technician. After the initial test burn, monitor the flue gas temperature to ensure it stays below 120 °C, indicating efficient combustion. Adjust burner settings if necessary, check the flame sensor, and calibrate it per the manufacturer’s guidelines. Inspect the fan motor for abnormal noise or vibration; replace the bearing if needed. Verify that the room temperature rises to the setpoint within the specified time frame, record all measurements, and troubleshoot any deviations by inspecting gas pressure, air‑to‑fuel ratio, and condensate drain for blockages. Once all parameters are within tolerance, perform a final safety check, including the RCD trip test, label the boiler with the installation date and technician’s signature, and schedule routine maintenance every 12 months to maintain efficiency and prolong lifespan.
Electrical and Gas Connections
The Alpha Evoke 28 requires a dedicated 32 A circuit with a 30 mA RCD. Connect the live, neutral, and earth to the boiler terminals, ensuring correct polarity. Use a 1.5 mm² cable for the power supply, routed through the wall cavity and protected by a conduit. The gas line must be a 16 mm flexible pipe, fitted with a pressure regulator set to 0.5 bar. Tighten all gas fittings with a 10 mm wrench and perform a hydrostatic test at 1.5 bar for 5 minutes. After the test, install a check valve and a 5 mm diameter condensate drain with a 5 % slope to the external drainage system. The boiler’s condensate return must be insulated with foam to prevent heat loss. Verify that the flue is correctly positioned, with a 45 mm clearance from the wall, and that the flue pipe is insulated with a 20 mm high‑temperature sleeve. All connections should be tightened to the manufacturer’s torque specifications. Finally, perform a leak test using soapy water on all gas and electrical joints. Document the installation in the logbook, noting the date, technician, and any deviations from the standard procedure. Ensure that the gas pressure regulator is calibrated to the manufacturer’s specified range, and verify that the combustion chamber is free of obstructions. The boiler’s internal safety valve must be inspected for proper operation, and the flame sensor should be cleaned if soot buildup is detected. All wiring connections must be tightened to the specified torque, and the isolation switch should be tested for correct function. Document any adjustments made during the installation, including changes to the gas pressure or electrical settings, and provide a detailed log for future maintenance. The final step is to perform a commissioning test, monitoring the boiler’s start-up sequence, flame stability, and heat output to confirm compliance with performance specifications. and.!

Troubleshooting Common Issues
When the Evoke 28 fails to heat, first check the power supply and ensure the main breaker is on. If the boiler lights but stays off, verify the gas valve is open and the pressure gauge reads within the 0.5–1.2 bar range. A low flame or no flame often indicates a blocked burner or dirty air filter; clean or replace as needed. If the unit displays error code 0x12, it signals a fan‑motor fault—inspect the fan for debris and test the motor with a multimeter. Error 0x23 points to a faulty pressure sensor; recalibrate or replace. A persistent “condensate overflow” message means the drain line is clogged; clear with a plumber’s snake or replace the pipe. For “high‑temperature” alarms, check the combustion chamber for soot build‑up and clean the heat‑exchanger fins. If the boiler cycles on and off rapidly, the thermostat may be mis‑calibrated; adjust the set‑point or replace the thermostat. Finally, always consult the error‑code table in the manual before attempting repairs, and contact a licensed technician if the issue persists.
Check the pilot light for a steady flame; if it flickers, clean the burner. Verify the pressure regulator’s set‑point matches the manufacturer’s recommendation. If the boiler still fails, inspect the condensate line for blockages and clear it. Log each maintenance event for warranty compliance.
