Frequently asked questions

No, it doesn’t expire. The gas inside will stay pure until it is used up. The gas cylinder cannot be refilled though.

The cylinders are pin activated, so when the regulator is removed, the gas will not leak. 

No, the cylinders are disposable and shall not be refilled.

No, the Air Admittance Valve (110mm) and the Air Admittance Valve (with Adaptor for 32-40-50mm) are intended for in cupboard use, not on roofs.

The 250 MJ and 500 MJ manual dual stage regulator, 400 MJ auto dual stage regulator and 160MJ dual stage regulator kit are manufactured in Italy, by Cavagna.

No, they must be installed with the vent facing down as per the manual. 

When using the 250MJ or 500MJ manual dual stage regulator and the160MJ dual-stage regulator kit, no, it’s for outdoor use only.  

When using the 400MJ auto dual stage regulator, yes, 3/8” NPT F.

When using the 250 MJ and 500 MJ manual dual stage regulator and the 160MJ dual-stage regulator kit, no, they can be either open or closed. As long as the cylinder in usage is open and both pigtails are connected. When the cylinder empties, the manual changeover valve is switched over and the corresponding gas cylinder should also be opened. 

If you are using the 400MJ auto dual stage regulator, to operate it the auto changeover, both are open. To use it like a manual changeover, the reserve cylinder can be turned off (will have to be turned on when the first cylinder runs out). Both cylinders need to be connected to the regulator via pigtails at all times. 

The 250MJ, 500MJ manual and 400MJ auto dual stage regulators don’t have an UPSO. 

No, the Bromic regulators are approved to UL144. According to section 15.3, we have a type 2 pressure relief valve instead of an OPSO. This relieves pressure through the vent, so the pressure downstream doesn’t exceed 14kPa.
