What it is
The Alpha Connection Group Cover is a replacement cover for the connection group assembly on Alpha heating appliances. It sits over the connection group, shielding the pipework joints and valve connections beneath from dust, knocks and accidental contact during servicing. The cover is supplied under Alpha part number 1.039203 and is also listed under the shorter number 039203.
As a moulded cover rather than a working component, it carries no water or gas path of its own, but it protects the parts that do. A cracked or missing cover leaves the connection group exposed, which makes routine work around the appliance less safe and can allow debris to collect around the joints.
Signs this part needs replacing
- Cracks, splits or chipped edges in the moulded cover
- The cover no longer clips or seats securely on the connection group
- Cover missing altogether, leaving the connections exposed
- Heat discolouration or brittleness that makes the cover crumble when handled
- Damage noticed during a service or after work in the appliance casing
Before you order
- Match the number 1.039203 against the marking on the existing cover before ordering
- Confirm the appliance model and, where shown, the GC number so the correct variant is supplied
- Check whether any gasket or seal at the connection group needs renewing at the same time
