Valves and fittings

• Fill valve with 80% stop: a float closes the inlet at 80% of capacity, leaving room above the liquid for the gas to expand. 3/8" NPT female thread, 3/4" UNF (JIC) with the supplied elbow.
• Manual outlet valve with 1/4" NPT thread and W21.8 LH adapter. It draws gas from above the liquid, so your appliances receive vapour.

The tank is fixed to the chassis on two U-brackets, supplied with bolts and washers. The tank is mounted horizontally, with the valves set at the angle given by the mounting mark on the tank.
