Radiant tube heaters will expand and contract during operation. Therefore it is essential to provide a
flexible metallic hose, which must conform, to national or Local Regulations, to connect the appliance to
the gas supply. Minimum size to be ½" (12.7mm x 1m long) bore.

The gas pipe, flexible hose and connections must be self-supporting. The gas pipe work must not bear
any of the weight of the heater or any other suspended assembly.
