Initial Setup & Commissioning
Before first use, proper initial setup and commissioning are crucial for optimal performance․ This involves verifying the boiler’s installation adheres to current regulations and manufacturer guidelines․ Ensure a qualified Gas Safe registered engineer performs this stage․
Key steps include checking gas supply pressure, verifying flue integrity, and confirming correct electrical connections․ System filling with water to the correct pressure is essential, followed by bleeding the radiators to remove trapped air․
Commissioning also involves setting the correct boiler parameters, such as gas rate and temperature limits, tailored to your heating system․ Thorough testing confirms functionality and safety before regular operation begins․
Filling the System
Proper system filling is vital before the initial start-up and after any significant water loss․ Locate the filling loop – typically two flexible hoses connecting the boiler’s filling loop valve to the heating system pipework․ Ensure the system valves are in the open position․
Slowly open the filling loop valves to allow water into the system, monitoring the boiler’s pressure gauge․ The ideal pressure is usually between 1 and 1․5 bar (check your boiler’s specific requirements)․ Close the filling loop valves once the correct pressure is reached․
Be cautious not to over-pressurize the system․ If over-pressurization occurs, carefully open a radiator bleed valve to release excess pressure․ Regularly check the pressure and top up as needed․
Bleeding the Radiators
Air trapped in radiators can reduce heating efficiency․ Begin with the radiators furthest from the boiler․ Using a radiator key, slowly open the bleed valve – typically located at the top side of the radiator․ Listen for the hiss of escaping air․
Once water starts to emerge, tighten the bleed valve to prevent leaks․ Repeat this process for each radiator in your system, working your way closer to the boiler․ Monitor the boiler’s pressure; bleeding radiators can lower system pressure․
If the pressure drops below 1 bar, refill the system as described in the ‘Filling the System’ section․ Regularly bleeding radiators ensures optimal heat output and a quieter heating system․
