AR/ARE/HB Gas connection

The gas connection on the Ambi-Rad heater is R1/2 (1/2in B.S.P internal thread).
The gas supply must not be in the position where it is subject to overheating. 
A gas union service cock MUST be fitted in the gas supply close to the heater, but not onto the burner itself.

Correct Installation of flexible gas connection.

It is essential to provide some flexibility in the final gas connection by use of a tested and certified metallic hose to BS 6501 Part 1:1991 (minimum acceptable quality Type ‘B’ Class 1). When stainless steel flexible hoses are used the hose should be connected in a 180° bend without any strain or torsion. (See link below).

Note Take care when making a gas connection to the heater not to apply excessive turning force to the internal controls.
