Frequently Asked Questions - Solo 2 50 RS Baxi

How do I reset the Baxi Solo 2 50 RS boiler?

Locate the reset button on the control panel. Press and hold for 3 seconds until the boiler restarts. If the fault persists, check the pressure and refer to the manual.

What type of gas does the Solo 2 50 RS use?

It is designed for natural gas (G20). Do not use LPG or other fuels unless converted by a professional.

Why is my boiler not igniting?

Check the gas supply, ensure the power is on, and verify the thermostat is calling for heat. If the ignition fails, there may be a fault with the flame detection system.

How often should I service my Baxi Solo 2 50 RS?

An annual service by a Gas Safe registered engineer is recommended to ensure efficient and safe operation.

What is the normal water pressure for the boiler?

The normal working pressure is between 1.0 and 1.5 bar when cold. If it drops below 0.5 bar, you may need to repressurize the system.

Can the boiler be used for hot water?

No, the Solo 2 50 RS is a central heating only boiler. It does not provide domestic hot water. You will need a separate water heater.

How do I repressurize the system?

Use the filling loop (usually a flexible hose with valves) to add water to the system. Open the valves slowly until the pressure gauge reads 1.2 bar, then close both valves.

What does the fault code F1 mean?

F1 typically indicates a low water pressure or a pressure sensor fault. Check the pressure gauge and repressurize if needed. If the code persists, contact an engineer.

Is the boiler compatible with a programmer?

Yes, it can be connected to a standard 24V timer or programmer to control heating schedules. Refer to the wiring diagram in the manual.

Where can I find spare parts?

Spare parts are available from Baxi authorized distributors and selected heating merchants. Always use genuine parts for safety.

Accredited Company

Your Baxi Solo is a gas fired, room sealed central heating boiler providing heating for your home and domestic hot water where required.

OPERATING YOUR SOLO

BOILER THERMOSTAT KNOB

1 Remove lower door panel as shown.
2 Turn the boiler thermostat knob to the '0' position fully anticlockwise.
3 Turn on the main gas and electricity supplies to the appliance.
4 To light the pilot: Looking through the pilot viewing window press the gas control knob fully inwards and hold. Press in igniter button and release. Repeat until pilot ignites. Continue to hold in gas control knob for approximately 15 seconds and then release. Pilot should stay alight.

NOTE: If pilot fails to remain alight or is extinguished at any time, wait at least 3 minutes then repeat the procedure from the start of section "4". Once the pilot is alight it may be left on permanently.

5 To light the boiler: Ensure that all external controls, e.g. room thermostat, timer, etc. are calling for heat. Turn boiler thermostat fully clockwise to high setting. Main burner will then light.

It is recommended that the boiler thermostat is used on HIGH setting in winter and a minimum of n° 2 in summer to ensure adequate domestic hot water.

“Benchmark” Installation, Commissioning and Service Record Log Book

Please ensure that your Installer has completed the Installation and Commissioning sections of the Log Book, and hands the Log Book over. The details of the Log Book will be required in the event of any warranty work. Keep the Log Book in a safe place and ensure that the relevant sections are completed at each subsequent regular service visit.

1 Turn off the electricity supply to the appliance at the mains.

2 To turn off the pilot: Turn gas control knob to off position marked 0.

NOTE: The gas control knob cannot be depressed until ignition restart interlock device in gas valve has disengaged. This takes 60 seconds approximately.

3 Turn off the gas supply at either the appliance gas cock or the meter.

If your home is to be left unoccupied for long periods during cold weather, the whole system should be drained, unless a frost-stat is fitted. Your installer will advise you about draining the system.

NOTE: Depending on the design of your central heating system, the pump may keep running for approximately 3 minutes after any external controls e.g. timer, programmer have turned the appliance off. This is perfectly normal and is because your Solo 2 RS is fitted with a timed pump overrun to prevent overheating.

OVERHEAT CUT-OFF DEVICE

Your boiler is fitted with an additional safety device which shuts down the appliance should the system overheat. If the pilot is extinguished for no apparent reason and cannot be re-ignited, this overheat cut-off device may have operated.

NOTE: Any interruption to the electricity supply may cause the device to operate. In the case of persistent operation of the device, turn off the boiler and consult your service engineer as an appliance or system fault is indicated.

If the boiler wiring has been altered to allow gravity domestic hot water operation, the overheat thermostat will be inoperable.

RESETTING

To reset the device follow these instructions.

Allow the boiler to cool if hot.

Remove the lower door panel by following the instructions on the opposite page.

Locate the red/brown reset button adjacent to the boiler thermostat knob. Press the button to reset the overheat thermostat.

Re-ignite the boiler by following the instructions on the opposite page.

Warnings

If a gas leak is found or suspected, turn off the gas supply at the meter immediately and contact your Installer or Transco (under 'Gas' in the phone directory).

NEVER HANG CLOTHES OR OTHER ITEMS OVER THE APPLIANCE.

SERVICING YOUR BOILER

We strongly recommend that your Boiler is serviced annually for reasons of safety and economy. Your Installer or British Gas Service will be able to advise you.

THIS APPLIANCE MUST BE EARTHED Electricity supply:

A standard 230 volt \~ 50Hz supply is required. The appliance must be protected by a 3 amp fuse.

SAFE INSTALLATION

Installation of this appliance must be carried out by a CORGI Registered Installer and be in accordance with the relevant requirements of the current GAS SAFETY (Installation and Use) REGULATIONS and any other regulations applying in your area.

CLEANING THE CASE

The painted panels should be wiped with a damp cloth and then dried completely. DO NOT USE ABRASIVE CLEANING AGENTS.

SPARE PARTS

Any repairs to the appliance will usually be the responsibility of the Installer during the guarantee period after which spare parts may be obtained through approved Baxi stockists if required. Quote the appliance name, model number and where possible the part number when ordering spares. (A parts list is included in the Installation and Servicing Instructions.)

The minimum clear spaces needed around the boiler are:

Top: (For Pumped) 50mm (2 in) (For Gravity) 80mm (3 18 in)

Bottom: 50mm (2 in) Sides: 5mm ( ^3/16 in) Front: 5mm ( ^3/16 in)

These clearances must not be obstructed in any way. Blocking the clearance spaces will result in the appliance overheating and possible damage may occur.

The gas burning compartment of your boiler is completely sealed from the room in which it is fitted. Products from the combustion of gas are vented to the outside through the flue terminal which must be kept free from obstruction as this would interfere with the correct operation of the boiler.

If the boiler is fitted in a compartment, this should be fitted with ventilation openings at high and low level which must not be blocked. Occasional checks should be made to ensure they are clear. The compartment should be large enough to house the boiler and ancillary equipment only.

IT SHOULD NOT BE USED AS A STORAGE CUPBOARD.

300mm is required for servicing. 5mm is required when operating.
