Manual outlet tap ( Valve Fitment 1 )
This is the first valve that you must fit in this order.
We assume in the instructions below that the tank you are fitting this valve it is a brand new unused tank. If the tank has been used with LPG you need to make sure the tank is totally empty and there is no pressure left in the tank ( when you open the tap ) and it is made safe before working on it.
When fitting the manual tap into the tank you need to make sure the thread in the tank is clean.
On the brass tanks valves with a thread there is normally a blue sealant paste which has been applied at the factory. We still recommend you use a liquid PTFE paste as an extra part when fitting the valve ( Added to the blue on the valve ) as this will add sealing the valve in the tank plus it also acts a lubricant to help install it.
This valve must be fitted so the float can drop perfectly vertical inside the tank so when you tighten the valve it does not get damaged by the other items in the tank. This means you must have the valve plate facing upwards ( at 12 o clock ) and it must be horizontal so the valves drop down inside.
When assembling the outlet tap into the tank, once again uses PTFE sealant and then make sure the valve faces out of the left hand side of the GAS IT airbox - follow the manufacturers torque setting!
Please read and follow the attached manufactures instructions for the required torque setting and for correct fitment of the valve - See attached document.
We find that for the installation of the 3 valves ( 1, 2 & 3 ) into the tank its self we do 5 complete turns and then the extra turn that might be needed to point the valve in the right direction as per the picture above
If you are unsure please contact GAS IT technical support before proceeding further as we can not be held responsible for any damage or incorrect functionality of the valves when you have fitted them in the tank.
Once all valves are fitted, please carry out a leak check using air, then drain the air and then carry out a further leak check with LPG vapour - using certified Leak detection spray on all the joints you have assembled. Do not fill with liquid LPG until you are satisfied the tank is LPG vapour tight first and then only fill using no more than 2 ltrs of Liquid LPG to allow further leak checking. Then continue to follow the install set up instructions here on the on the GAS IT knowledgebase here
