  • Page 16: Fitting Of The Atmos Heating Jacket

    The inner heating jacket assembly (1) consists of two “C” section metal bodied parts that are hinged together allowing for the heating jacket to be opened and to fit around the metal body (28) of the Atmos gas cell. When fitted around the metal body (28), the hinged C-section parts of the inner heating jacket (1) are closed together and held securely shut by a tab clip bracket mechanism (2).
  • Page 17 The outer insulating jacket (3) consists of a heat resistant fabric casing surrounding the metal inner heating jacket (1). When the inner heating jacket (1) is closed to fit around the Atmos gas cell metal body (28), the outer insulating jacket (3) can be placed to cover and envelop the heating jacket (1).
  • Page 18 Fitting the Inner Heating Jacket (1) to the Atmos Gas Cell Having removed the Atmos gas cell from any Lever-lock baseplate mount fixing, position the Atmos gas cell onto a level workspace area. With the outer insulating jacket (3) removed, open the inner heating jacket assembly (1) (as seen in Fig 1.) by undoing the clip tab bracket...
  • Page 19 With the inner heating jacket (1) parts opened as wide as possible, carefully lift the heating jacket assembly (1) to lower over and surround the metal body (28) of the Atmos gas cell. The underside edge of the heating jacket assembly (3) should come to rest on the top surface of the lower screw fixing flange ring for the Atmos gas cell body (28).
