2.
Locate the cylinder and regulator in a locker vented to the open air (preferably on
the deck or cabin top) isolated from the hull interior by a vapor tight enclosure.
Refer to local codes or Coast Guard requirements for details.
3.
Propane is heavier than air. Therefore, the locker in which the cylinder is
installed must be vented at the bottom. Position the vent above the water line, and
at least two feet from any hull opening to the boat interior or engine exhaust.
a)
We recommend the installation of a vapor monitor on your boat with all
propane fueled devices.
4.
Propane is a two-phase (liquid/vapor) fuel, and only vapor withdrawal from the
tank is safe. Firmly mount the cylinder, right side up, to ensure that liquid
withdrawal does not occur.
a)
We recommend that a solenoid valve, which can be controlled by a switch
located in your cabin, be installed next to the manual cylinder valve. The
cylinder valve outlet and the 9V or 12V DC solenoid valve should be
clean and dry when they are connected to each other.
5.
Unnecessary attempts to seal this connection with substances like pipe dope or
Teflon tape can result in the introduction of foreign materials into the system that
can plug the tiny appliance orifices.
6.
A 0-300 psi (0-20 bar) pressure gauge should be installed next to the solenoid
valve on its downstream side. Again, the fittings should be clean and dry. It is
not necessary to use pipe dope or Teflon tape for these connections.
7.
Install the regulator downstream from the pressure gauge with its vent port
pointing downward, which prevents spray or deck wash from entering the fuel
system.
