Access Panel

Gas Flue Inspection

Specifically designed and tested to comply with the Gas Safe Regulations this panel provides a high quality robust opening solution to inspect flues installed in voids. In addition to the two sizes required by the legislation The Access Panel Company can manufacture compliant hatches to any size.

Since January 2013 Gas Engineers must be able to inspect the full length of the flue from the boiler. In many circumstances this is not a problem. However in apartment buildings and flats where space saving advances have allowed boilers to be fitted in wall spaces the whole flue may not be visible for inspection. In these circumstances an access panel is required for inspection.

Failure to install an access panel to facilitate inspection will mean that the Gas Engineer will deem the boiler “At Risk” and recommend it be turned off until a full flue inspection can be made.

The panel is available with two frame options that suit both a retrofit as well as a new build scenario. The two frame types are: A beaded frame type (SBF) with perforated flange to key into the surrounding membrane. This is used where the surface has yet to be skimmed or tape and jointed. Or the picture frame, (PF), where the solid flange sits on the surface of the wall. This covers the cut edge of the aperture and is used when the surface has already been finished and decorated.
