CSA 6.27:2016 pdf download.Connectors for outdoor gas appliances and manufactured homes
1.1 CSA 6.27 applies to newly produced assembled connectors constructed entirely of new, unused parts and materials. Such connectors are intended for exterior use above ground for making the following non-rigid connections:
a) between the gas supply and the gas inlet of an appliance for outdoor installation that is not frequently moved after installation. These connectors are not intended for use with wheeled,caster mounted, or portable appliances;
b) between the permanent gas outlet of a manufactured home community (mobile home park) or individual site and the piping inlet on a park trailer or a manufactured (mobile) home; or
c) between sections of a multiple section manufactured (mobile) home.
4.4.4 The instructions shall include statements that the connector:
a) is not to be used for connection to an LP-gas container mounted on or adjacent to a park trailer or the manufactured (mobile) home;
b) is not to be installed underground or for use in contact with the ground; and
c) is designed for occasional movement after installation. Repeated bending, flexing, or vibration must be avoided. Normal operation of a clothes dryer, rooftop HVAC unit, or similar outdoor appliance does not constitute extreme vibration or movement.
4.4.5 Unless tested for such use under another standard, the instructions shall include statements that the connector is not for connecting appliances within a recreational vehicle, park trailer, manufactured (mobile) home, a residence, or commercial building.
4.4.6 The instructions shall include statements to the effect that:
a) a readily accessible manual shutoff valve must be available upstream of the connector assembly;
b) the connector must not be concealed within or run through any wall, floor, or partition. The entire connector must be visible for inspection;
c) the connector shall be of an appropriate length for the intended application. Do not stretch the connector or bend it smaller than 1/2 in (38.1 mm) internal diameter (approximately the size of a golf ball). Make sharp bends with pipe fittings;
d) the connector must not be kinked or twisted about its own axis;
e) contact with foreign objects or substances must be avoided;
f) the final assembly must be tested for leaks. CAUTION: Test for leaks only with leak test solution.
Rinse with clear water after leak testing to remove any corrosive residue. DO NOT USE OPEN FLAME TO TEST FOR GAS LEAKS;CSA 6.27 pdf download.
