GENERAL
Install the TORREXX
TM
vaporizer on a level firm base at least 6” (15 cm) above
grade and secure it through the four ½” (13 mm) holes. Protect the equipment
against damage from moving vehicles by use of an appropriate barrier. Consult
state, provincial, insurance carriers, and local authorities for installation
requirements. Clean all foreign material from all pipelines prior to making final
connections. All joints require a pipe sealant approved for LPG, depending on
type of service. Test for leaks using an inert gas, such as compressed carbon
dioxide or nitrogen, at 1½ times the working pressure or as required by
applicable codes. Check all connections using an appropriate leak detection
solution or device. Even very small leaks are unacceptable. Eliminate all leaks
prior to operation. Ensure installation environment does not exceed 50°C.
Install in accordance with applicable codes and local regulations as required.
Explosion p
roo
f seal off must carry the same approvals as the va
porizer to
maintain the approval of the overall installation
.
Figure 5 - Typical TORREXX Installation Drawing with Pump & Vapor Bypass
Note: The vapor bypass line is not required except when you have the Economy Operation option.
However, it is recommended to install a bypass line on all installations because it will provide a back-
up supply of vapor from the tank to the load in case of vaporizer failure or power interruption.
Vaporizer will operate properly without the bypass.
