1. Before commencing with the installation, carefully read all sections of this instruction booklet, including the WARNING
section and the installation correct/incorrect section. Installation work should only be carried out in accordance with
BS 6173 by a Gas Safe registered installation engineer.
2. The accessible manually operated shut-off valve shall be installed in accordance with BS 6173:2001. This gas isola-
tion valve (A) must be in the ‘off’ position. If there is no local gas isolation valve fitted, the main gas isolation valve
must be turned off. Do not commence with installation unless the gas supply is fully isolated.
3. Remove the Dormont gas hose and fittings from the bag/box.
4. The location of the gas connection point on site in relation to the gas connection point on the appliance can vary
greatly. It is not possible to illustrate every possible installation combination, and these instructions illustrate a few
examples. The installation engineer must take great care to ensure that the gas hose is not kinked, twisted or taut
when installed, and that the end fittings of the gas hose are not subjected to sharp bends. The installation shall be
such as to avoid excessive flexing, bending or vibration in service. Please refer to the section of this manual for
correct and incorrect installations. For installation situations where sharp bends are a possibility, or are unavoidable,
Dormont Swivel MAX

fittings are recommended.
5. It is recommended that the connection point for the hose at the installation end is fixed at 600mm – 770mm AFFL and
is facing downward. This is dependent upon the length of hose to be used and the gas connection position on the appli-
ance. The gas outlet, to which the hose is to be connected, shall be located in the same room as the appliance. The gas
hose assembly must not be concealed within, or run through any wall, floor, or partition. The gas hose must not come
into contact with the floor during use.
6. To facilitate moving of the appliance as close to the wall as possible, the
two ends of the gas hose should be offset from each other (refer to figure 2).
7.
The quick-disconnect coupling must be fitted so that the gas enters the
female half (valved) of the coupling and exits the male (nipple) half. Follow
the gas flow direction arrows permanently marked on the coupling.
APPLIANCE SIDE:
8. In order to achieve correct curvature of gas hose, it may be necessary to fit a
90 degree elbow to the appliance connection point (E) fig.1.
Apply appropriate thread jointing compound and tighten into position required.
9. End fittings are supplied bonded into the ends of the Dormont gas hose. Apply appropriate thread jointing compound
to the end fitting threads, and wind the end fitting/gas hose (D) assembly into the appliance connection point.(E.)
10. Ensure that the gas supply and all the appliance control knobs are turned off before connecting to the gas supply.
GAS SUPPLY (INSTALLATION) SIDE:
11. Separate the female half of the quick-disconnect coupling (B) from the male (nipple) half (C) that is bonded into the
end of the gas hose.
12. Apply appropriate thread jointing compound, and thread the female half of the quick-disconnect coupling onto the
supply pipe from the gas isolation valve (A.) Tighten into position.
13. Connect the quick-disconnect nipple (C) into the quick-disconnect female (B.)
14. On completion, the final assembly shall be tested for leaks at all joints. Leak test in accordance with accepted
procedures. Leak test solutions can cause corrosion, so thoroughly rinsing with water is required. Caution: A naked
flame shall not be used for this purpose.
15. When installation of the gas hose is complete, carefully push the appliance back into the required operating position.
Check that the hose is not kinked, over bent, caught under the appliance casters, or touching the floor. Ensure that the
appliance controls are in the off position before turning on the gas supply.
