<p>The invention relates to a connector 20 for delivering combustion gas to a gas fired appliance 22 from a stationary supply line 24 where the appliance 22 moves toward and away from the supply line 24 with the connector 20 straightening and flexing between them as the appliance 22 moves. The connector 20 comprises a flexible hose assembly 50 and first and second swivel fittings 52, 54 at respective hose assembly ends. Each swivel fitting 52, 54 defines a gas flow path and comprises a swivel member for communicating the connector 20 with the appliance 22 for the supply line 24. The hose assembly 50 comprises a flexible metal hose member 56 and antitorsion fittings forming ends of the hose assembly 50 connected to respective swivel fittings 52, 54. The antitorsion fittings comprise pintle and nipple members rotatable relative to each other to prevent torsional stress in the hose member 56 when the appliance 22 moves relative to the supply line 24. <IMAGE></p> |
