Propane Fuel System - venture SPORT TREK Owner's Manual

1. Costly—would take 6 to 10 gallons more antifreeze.
2. Antifreeze can be very corrosive to anode rod causing
premature failure.
3. Leaves sediment in the water heater.
Using the Water System in winter:
Your towable RV was not intended to be used during freezing weather
unless special precautions are taken. Water freezes at 32 degrees.
There is no product that can be added to the water to ensure freeze
protection when the system is in use, other than RV antifreeze. DO NOT
DRINK WATER WHICH CONTAINS ANY TYPE OF ANTIFREEZE.

Propane Fuel System

The fuel system in your recreational vehicle has numerous components
such as, piping, copper tubing, brass connectors, hoses, regulators and
appliances. Each of these components will be explained in its appropriate
area.
Propane is the only fuel permitted to be used in a recreational vehicle and
its appliances. This product is refined from crude oil through natural
gasses. An agent has been added for detection should a leak occur or a
valve accidentally be left open. It is important for a recreational vehicle
owner to recognize and identify the odor of propane vapor.
Other fuels are available, but cannot be used in a RV because:
1. No orifices for appliances are available for either butane or
natural gas fuels.
2. Butane also cannot be used below freezing temperature
because boiling point is 30 degrees F.
Propane fuel is stored in liquid form under high pressure in special
containers. Boiling point is (MINUS) — 44°F, the temperature when
vapor ceases to flow. Fuel will change to vapor when released from the
container. Appliances are not designed to operate with liquid. Liquid will
damage O-rings in valves and also leave sticky, oily residue causing poor
or no operation in the regulator.
For every 10 degree increase in temperature, the pressure in container
rises 1.5%. Example– fill at 0 degrees in north, go south to 80 degrees
warmer, you now have container filled at 92%, a potential problem with
10% valve spewing out propane vapor.
DO NOT use Ethylene Glycol (automotive antifreeze) or
Methanol (windshield washer antifreeze) in your fresh water
system because they are harmful and may be fatal if
swallowed!
