Installation Manual for Ximax Bristol Designer Radiator

Quick Guide

This manual provides instructions for the assembly and installation of Ximax designer radiators. Before starting, ensure you have all necessary tools and that the wall is suitable for mounting. The radiator must be installed by a qualified plumber or competent specialist. Always check the specific dimension tables provided in this manual for your model to ensure correct bracket placement.

Safety and Preparation

Before beginning the installation, please observe the following safety guidelines:

• Professional Installation: The radiator must be installed by a qualified plumber or competent specialist.
• Wall Suitability: The supplied wall plugs are suitable for solid masonry only. For other wall types, obtain the correct fixings.
• Safety Gear: We recommend wearing protective clothing, such as gloves and reinforced work shoes, during assembly.
• Site Preparation: Ensure there is enough space and a clean, dry environment. Before drilling, verify that there are no hidden water, electric, or gas lines behind the wall.
• Clearance: Maintain a distance of at least 150 mm between the floor and the bottom of the radiator for efficient heating and ventilation.

Assembly Instructions

Follow these steps to mount your radiator:

1. Drilling: Using the dimensions from the assembly dimension table, drill 4 holes with a depth of approximately 60 mm and a diameter of 8 mm.
2. Plugs: Insert the supplied wall plugs (C) into the drilled holes (solid walls only).
3. Brackets: Attach the screw (D) and washer (E) to the bracket. Do not overtighten the screw.
4. Mounting: Hang the radiator on the bracket.
5. Valves: Mount the supplied air valve (A) and blanking plug (B) in the upper threaded openings.
6. Connection: Connect the flow and return to the selected side using radiator valves (not included). Use PTFE tape or similar sealing product to ensure watertight connections.

Filling and Venting

Proper filling is essential for system efficiency:

• Open the air vent.
• Slightly open the inlet valve (about 10%) while keeping the outlet valve closed.
• Allow the system to fill the radiator slowly.
• Once filled, close the air vent.
• Open both inlet and outlet valves fully and run the heating system for about 2 hours.
• Close both valves, open the air vent to release any remaining air, then close the vent.

Care and Maintenance

To ensure the longevity of your radiator:

• Rinsing: After installation, ensure the system is thoroughly rinsed to flush out metal, flux, and debris.
• Inhibitor: Add a suitable inhibitor to the central heating system when filling to prevent internal rust and limescale.
• Cleaning: Clean the radiator with a soft, damp cloth. Never use scouring pads, scouring agents, or chemical cleaning agents.

Troubleshooting

If the radiator is not heating correctly:

• Cold Pipes: Check and vent the radiator again using the air vent. If the problem persists, the radiator may have been filled too quickly; try running it on its own to force air out.
• Patchy Heat: If the radiator heats unevenly or takes a long time to heat, it may have been installed upside down. Check the baffle position inside the tube.
• Electric Radiators: A small amount of water discharge from the pressure valve on first use is normal. If the radiator does not heat, it may need to be topped up with water.
