LPG FUEL TANK INSTALLATION

LPG TANK WITH REGULATION SYSTEM
1. Locate the tank and regulator on deck, cabin top or in a vapor tight compartment, insulated from the
hull interior and protected from climatic extremes by a housing vented to the open air. The vent
should be at the bottom of the compartment so that if the LPG should leak from the system, it will
drain overboard. .
NOTE:
LPG is heavier than air and if allowed to settle or accumulate, and if ignited, it WILL
CAUSE AN EXPLOSION!!
2. The LPG tank should be securely bolted down by the tank feet and in the position in which the tank
was designed. LPG is a two-phase (liquid/vapor) fuel and only vapor withdrawal from the tank is
safe. Liquid withdrawal from the tank could be dangerous.
3. IMPORTANT: The LPG tank valve outlet fitting and regulator system nut, by law, must have left-
hand threads. The nut is so marked with a slot.
4. The LPG tank valve outlet fitting does not require pipe dope or Teflon tape and should be attached
to the regulation system nut dry and clean to keep foreign materials out of the system. When
assembling the regulation system, use a high quality sealant only on all male pipe threads.
5. The regulator must have a 0 to 300 psi pressure gauge located on the tank pressure side of the
regulator.
6. If the LPG tank is to be located on deck or exposed to water spray, point the regulator system so
that water cannot run into the regulator vent port located just above the LPG outlet connection, or
into the body of the pressure gauge.
7. Use a 7/8” open end wrench to tighten the regulation system nut to the LPG tank valve connection.
Tighten the nut as you would on welding tanks or CO2 cylinders, using approximately 50 foot
pounds torque.
8. Affix the caution label supplied with the stove in the immediate vicinity of the tank where the label
will be plainly visible. (Refer to ABYC Standard #A-1)
9. The LPG supply line should be U.L. listed hose with machine-crimped fittings. A single continuous
hose without couplings or tees is strongly recommended. Keep the number of fittings to an absolute
minimum. Every connection is a potential leak!
10. Run the hose from the LPG regulation system to the appliance with 6 – inch minimum radius turns,
so the hose does not kink, cutting off the fuel supply to the appliance. Note: Fuel pressure is less
than ½ psi.
11. Keep hose away from heat or abrasion. Use plastic ties or clamps to secure the hose to the boat
structure or bulkheads .
