Natural gas whip. Grade "T", right?
I want to put my clothes dryer on casters so I can
scoot it out of the way conveniently when cleaning it's exhaust duct. It now has the industry-standard corrugated metal gas line. I assume that a grade 'T' neoprene line would be safer because it would not have the metal fatigue issue I ASSume would claim the corrugated line at some point in the future. I DAGS but was not able to uncover a hose with the right connectors. What am I doing wrong here? --Winston |

As far as the cleanout problem, my dad used an elbow and short section of vent that could be pulled and the works rodded out when needed, My sister's dryer is set up with a flex plastic vent, ala giant vacuum cleaner hose, that can be disconnected easily. On both, the dryers are set so they aren't easily moved, but have space on sides and back so that the vent is easily reached, the installations were designed that way. IANAL, but if you use a non-approved connection and have a fire, your insurance will probably not pay off, no matter how clever your hose and castor setup is. Stan |

(...) Try a restaurant supply place, stuff like commercial convection ovens are frequently on casters and frequently have flexible gas connections with quick connect fittings (secondary shutoff valve behind the quick connect). Good! Thanks, Pete! --Winston |

And they also put on aircraft-cable "leashes" between a stout ring on the wall and a stout attachment on the restaurant ovens and fryers, so when they are rolled out for cleaning (or decide to go Walkies on their own in an earthquake...) they stop at the cable first. This way the gas whip hose isn't what is trying to stop the appliance, or getting ripped open and make a major gas leak if the appliance won't take No for an answer. You're blending several different chapters of the Building Codes Residential and Commercial uses are treated vastly differently - and sometimes for no logical reason. You might want to ask the local "Authority Having Jurisdiction" (building inspector) and your insurance company to see if they have any concerns. If they find it after the fire, even if it had nothing at all to do with it, you're still in a world of trouble. -- Bruce -- |
