♦
Next, install a pressure regulator with a high temperature
Fluorocarbon elastomer (Viton) seat no more than 1 meter (3
feet) after the vaporizer outlet. Install this regulator as close to
the outlet of the vaporizer as possible and always at a higher
elevation than the vaporizer outlet to allow any condensed liquid
to travel back to the vaporizer. Never install the regulator more
than 1 meter (3 feet) from the vaporizer. If you are using PE
pipe after the regulator, ensure that it is connected at a
minimum 2 meters (6 feet) after the vaporizer.
♦ Install a pressure gauge in the regulator or at the regulator
outlet.
♦
After the regulator, install a “drip-leg” in the piping or a vapor
filter to collect any residue or heavy-ends from the LPG. The
drip leg should terminate with a valve and a plug for draining.

Relief valve
For horizontal installation, no modifications to the relief valve
orientation are required. For vertical installation, ensure that the
relief valve vent is piped in a vertical orientation. This may be
achieved by using a pipe away adapter with a ½” NPT pipe nipple
and ½” NPT F x F elbow, or by switching the LPG outlet adapter
with the pressure relief valve to ensure the pressure relief valve
vents upwards. Leak test new piping connections during
commissioning.
Note: When mounting vertically, always ensure that the LPG
inlet and the outlet end of the vaporizer are on top.
