Removing a LPG fill hose to add a 2nd GAS IT refillable bottle
All GAS IT bottles, and our GAS IT tanks for that matter have a excess flow valve fitting in the 80% shut off fill valve, so should you need to remove the fill hose to add a 2nd bottle or gas tank or the fill hose gets cut then the EFV ( Excess Flow Valve ) in the tank or bottle will see a full pressure drop and automatically shut off.
Even though our products have check valves in the fill valves, we always recommend that any fill hose or bottle connection is removed only when the bottles or tanks are completely empty of LPG and that the work is carried out by a trained GAS IT installer due to safety implications.
Don't forget that there is a high possible chance that the fill hose will have full pressure liquid LPG in it so when you come to remove the fill hose you need to 100% commit to removing the hose for the EFV in the bottle or tank to shut. If you only open the hose fitting a little way then the liquid will come out, it will freeze the fittings and might then not shut off as the EFV will be frozen - plus it will likely empty the tank or the bottle fully.
If you are removing the bottles or GAS IT tank and storing them for some time we always recommend you that you have a the 2 parts from the GAS IT removal kit to hand so that you can shut off the manual tap outlet and the fill valve elbow on the bottle ( if you removing the fill hose and fillpoint from the bottle or tank.) These are our part number GI-VAL-V-029 & GI-FH-033 which are sold on our GAS IT webshop
Before you do any work on LPG products or anything that has had gas in them its safety, safety safety.
This information is for GAS IT trained dealers only. We always recommend getting a trained GAS IT dealer to carry out any LPG work on your GAS IT products because liquid LPG freezes the skin on contact so wear gloves with a coating that stops them getting wet with liquid LPG, wear safety glasses and evena full face mask to stop liquid LPG hitting your face, cover up exposed skin. Watch out for ignition sources from naked flames, electrical connections ( 240 or 12 volt ) and also make sure you are not near open holes or grids as LPG is heavier than air and will find the lowest point.
