Features:

• 110x300mm x 1¼"/1½" (32mm) pipe top and side inlet connections.

• 19/23mm x 32mm solvent weld fitting provided to increase size of discharge pipe before it passes through external wall.

Installation Guidelines on Condensate Discharge:

• The condensate from the boiler should, where possible, be discharged into the internal drainage of the household drainage system.
• Internal condensate discharge pipework must be a minimum diameter of 19mm (which is generally viewed as 22mm OD) and must be of corrosion-free plastic pipe.
• The discharge pipework must ’fall’ at least 45mm per metre away from the boiler and take the shortest possible route to the discharge point or waste system.
• It is recommended if the condensate pipework has to be taken externally to the termination pipe, the pipework should be no less than 32mm in diameter - The external pipework should be as short in length as possible and should be protected with waterproof lagging from extreme weather conditions.
• Where the boiler already has an internal trap, no other trap should be installed as this will cause the boiler trap to malfunction.
• Waste pipe fittings should be kept to a minimum as the discharge flow should be as free as possible.
• If the discharge pipe is terminated into a gully, the pipe should be cut below the grating cover and above the water level - The pipe end entering the gully should be cut at 45Degree.

External Installation to a Soakaway:

• When installing a soakaway the ground conditions must be taken into consideration - It is recommended that the soakaway is not installed near any service pipework such as water or electrical mains cables and the installation of the soakaway should be a minimum of 500mm away from the building.
• The McAlpine soakaway should be installed in a hole depth of approximately 400mm minimum x 200mm in diameter.
• The soakaway should then be placed in the hole with the cut holes in the soakaway facing away from the foundations of the building.
• The soakaway should then be filled with 10mm limestone chippings.

Soakaway Installation:

• The condensate pipework may terminate above or below ground level - If above ground the condensate pipe must be protected with a waterproof lagging.
• The pipe end entering the soakaway must be at a depth of 25mm minimum and the end of the pipe cut at 45Degree.
• It is recommended that the soakaway is inspected during the annual service of the boiler.
