7.3.2 Although propane gas is odorless, a special ingredient is
added to impart a distinctive odor to the gas as an aid in
the detection of leaks. Should this odor be detected in
the vessel when the equipment is thought to be secured, or
if a leak is suspected for any other reason, it is impor-
tant that steps be taken to find the cause. If the leak
cannot be found, or if doubt exists about the ability to
effect repairs, the services of qualified technical person-
nel should be employed.
A simple test procedure that can be used to check
system for leaks is as follows:
a. Ensure that the switch on the electrical panel is
in the OFF position.
b. Open the cylinder shut-off valve and observe the
pressure reading on the gauge.
c. Close the cylinder shut-off valve. On a system
free of leaks, the reading on the gauge will
remain constant for several minutes after the
valve is closed.
d. If a leak is suspected beyond the solenoid valves,
repeat steps 2 and 3 with the electrical panel
energized and the burner valves closed.
WARNING!
NEVER USE AN OPEN FLAME SUCH AS A
MATCH OR CANDLE TO SEARCH FOR LEAKS.
the
A solution of soapy water applied to fittings, and a search
for bubbles with the system under pressure, is a safe,
useful procedure for localizing a leak.
7.4 Head and Waste Systems
The waste system is comprised basically of a marine toilet,
Y-valve, holding tank, and a series of valves and hose runs
for intake and discharge of sea water and waste.
The marine head intakes water through a 3/4" seacock
located in the forward end of the starboard settee. To
flush, open the seacock and the valve handle on the toilet
pump cylinder. Then pump the handle until the bowl is
flushed clean. Reset the valve handle to the dry flush
position.
The holding tank is located below the V-berth top. It has
a 25-gallon capacity and may be pumped dry via a shore
pumpout system connected to the deck plate marked "waste."
Limit pumping strokes at the head when discharging into the
holding tank to maximize its use.
