Lpg - Hunter H31 Operator's Manual

Fuel leaking from any part of the fuel system can
lead to fire and explosion that can cause serious
bodily injury or death. Inspect system before
Before fueling, check the fuel system for leaks. Check
components for weakening, swelling, or corrosion.
Immediately replace any leaking or defective compo-
nents before operating an engine. Keep the tank as full
as practical to reduce condensation and the accumula-
tion of moisture in the fuel system. In warm and hot
weather, allow for expansion of the fuel. A fuel tank may
overflow when the fuel expands after being pumped from
cool underground storage tanks or after fueling when air
temperatures are cool (night and early morning).
Follow these procedures to fuel your boat:
• Safely and securely moor your boat to the dock.
• Turn off engine.
• Turn main battery switches off to prevent sparks from
electrical equipment (lights, blowers, pump, etc.)
• Disconnect shore power if connected.
• Put out all cigarettes, cigars, pipes, or other items that
may produce a spark or flame.
• Ask guests to leave the boat during fueling.
• Remove cap from the fill pipe.
• Insert the fuel hose nozzle into the fill pipe. During
fueling, maintain contact between the nozzle and the fill
pipe.
• After pumping several gallons of fuel, inspect engine
compartment for any signs of fuel leakage.
• Fill the tank completely, allowing space at the top of
the tank for thermal expansion.
• Fill slowly near the top to avoid overflow.
• Remove nozzle after tank is full and replace fill cap.
• Make sure cap is tight.
Hunter 31 • Fuel Systems
fueling.
• After fueling is complete, open all hatches, doors,
and compartments.
• Visually check all fuel fittings, lines, and tanks for fuel
leakage.
• Check all lines up to engines and generator. Smell
for fumes.
• Correct any problem before you start the engines.
• Turn main battery switches on.
• Restart engine and restore boat to operating condi-
tion.
Do not smoke until your boat is clear of the fuel
dock.
Fuel vapors can explode. Do not smoke at the dock.
Extinguish all flames, stove, and other ignition
sources before you approach a fuel dock.
Explosive fuel vapors can become trapped in the
lower portions of the boat. Close all
windows, doors, and compartments while fueling
5.5 LPG (Liquefied Petroleum Gas) System
LPG (Liquefied Petroleum Gas) is a generic term to
describe liquefied gasses consisting predominately of
Propane (C3) and Butane (C4) hydrocarbons.
5.5.1 Hazards
Extremely flammable! These gasses readily form explo-
sive air-vapor mixtures at ambient temperature.
Vapor is heavier than air and may travel to remove
sources of ignition (e.g. along drainage systems, into
bilges, etc.).
Liquid from the tanks will generate large volumes of flam-
mable vapor (approximately 250:1).
