Piping
CAUTION
Teflon tape can clog orifices if not properly used. If a removed
fitting has Teflon tape, make sure to clean all threads and remove
all tape debris before re-installing.
The ZIMMER is designed for feed-through operation. If you are
using cylinders to store the LPG, you will need liquid withdrawal
valves in each cylinder. It is best to use valves that have both vapor
and liquid withdrawal ports – this allows you to use vapor when
your load is small or when the temperature is high, and then use
your vaporizer when the ambient conditions are insufficient.
Typical Piping Installation – Dip Tube
If you are using a tank to store the LPG, you will need to connect to
the bottom of the tank or to a connection that has a “dip tube”
extending into the tank for liquid withdrawal.
♦ Install an approved isolation valve at the outlet of the tank or
use the existing tank valve. If you are using cylinders you
should install an isolation valve after the cylinders have been
manifolded together. The isolation valve should have a
hydrostatic relief valve installed to protect the pipe section
between the valves.
♦
After the isolation valve, install a ½” or ¾” NPT strainer with a
size 40 or smaller mesh screen.
♦ Connect the strainer to the inlet of the ZIMMER using ½” or ¾”
pipe, Schedule 80, depending on the model.
NOTE
Do not install a check valve between the ZIMMER and the tank or
cylinders! Liquid must be able to back-flow if necessary.
♦
At the outlet of the ZIMMER install an isolation valve approved
for LPG vapor service.
