Liquid Propane (LP) Gas System
Your motorhome is equipped with a liquid propane (LP) gas system (Image 72.1) designed to provide fuel to the following appliances: refrigerator, range, furnace and hot water heater.
The propane tank (Image 72.2) is located outside of the motorhome. The main shutoff valve, also called the service valve is located on the tank and will need to be opened to operate your gas appliances.
The liquid propane (LP) gas system is designed to allow you to operate the motorhome with the propane tank turned on. This allows the refrigerator to cool as you travel.
NOTE: Close (twist clockwise) the service valve at the liquid propane (LP) gas tank (Image 72.2) before you begin refueling the motorhome liquid propane (LP) gas tank.
CAUTION: All gas appliances (Refrigerator, Range, Furnace and Water Heater) must be turned "OFF" before you begin to refuel the motorhome chassis with unleaded fuel as well as the liquid propane (LP) gas system.
Cold weather operation; in extremely cold weather there may not be enough heat outside to vaporize the liquid propane (LP) gas in your propane tank. This can reduce or even stop the flow of liquid propane (LP) gas to your appliances.
IF YOU SMELL GAS:
1. Extinguish all open flames, pilot lights and all smoking materials.
2. Do not touch electrical switches.
3. Shut off the (LP) gas supply at the service valve located on the (LP) gas tank.
4. Open doors and any other ventilating openings.
5. Leave the area until the odor clears.
6. Have the gas system checked by an authorized service technician to determine the source of the leak and to have corrected.
LIQUID PROPANE (LP) GAS/CO LEAK DETECTOR
The liquid propane (LP) gas/CO detector (Image 73.1) is an electronic device designed to detect and alert you of a possible liquid propane (LP) gas and or carbon monoxide (CO) leak in the motorhome.
The detector immediately warns you with a fast beeping sound. When you hear this sound, turn the liquid propane system off at the service valve located on the liquid propane (LP) gas tank.
It is important to note that the detector is sensitive to more than just liquid propane (LP) gas and carbon monoxide. Other combustibles that may be detected include alcohol, colognes, perfumes and most cleaning fluids.
The detector is located near the floor of the motorhome in either the entry step, kitchen or dinette area. The detector is powered by the coach battery(ies). When the battery voltage falls below 10.5V, the liquid propane (LP) gas/carbon monoxide (CO) detector will begin to chirp at a slow pace. if this happens, you will need to start the generator or the engine to allow the coach battery(ies) to recharge.
For startup or restart conditions, light one of the burners and allow it to burn for approximately thirty seconds or until the flame is burning evenly. If the stove will not light, see Troubleshooting the liquid propane (LP) gas system.
TROUBLESHOOTING THE LIQUID PROPANE (LP) GAS SYSTEM
The Refrigerator
Motorhome refrigerators (Image 75.1) are completely different from the ones you have inside your home. A motorhome refrigerator is an absorption refrigerator. Rather than applying direct cold, heat is drawn out from the refrigerator. There are no moving parts, the whole process is based on chemistry and physics, rather than mechanics. While effective, there are limitations inherent to the system.
The average cooling temperature of a motorhome refrigerator is about 60° Farenheit (15° Celsius) and it can vary depending on the outside temperature.
Avoid opening the refrigerator for extended periods of time as this will warm the refrigerator and its contents. This can cause a colling down period of up to 6 hours to get the temperature back down to 60°.
Each prolonged opening of the refrigerator door(s) can increase the temperature of the refrigerator by up to 10° Farenheit (6° Celsius).
Here are some helpful hints to help keep your perishable food items cold:
1. Pre-cool your food if possible. This gives the unit a break and keeps the temperatures down inside the refrigerator.
2. Proper refrigeration requires air circulation within the refrigerator. It is essential that the shelves are not covered with paper or large food items as this will restrict airflow.
3. Park your motorhome on as much level ground as possible. The refrigerator will not operate as efficiently if the motorhome is not level.
4. Don't open the door(s) more than necessary.
OPERATING INSTRUCTIONS
A 12V supply must be available for the electronic control of the refrigerator to function. The power is supplied by the coach battery(ies).
START UP: Push "ON/OFF" button (Image 75.2) so button is pressed in the "ON" position.
AUTO: In the "OUT" position, the refrigerator will automatically switch from liquid propane (LP) gas to electric as needed. Image 76.1 Refrigerator Warmer/Cooler Slide Control
GAS: With the button in the "IN" position, the refrigerator will run on liquid propane (LP) gas only.
TEMPERATURE CONTROL: Open the refrigerator door, you will see grated panels in the back. On the right side of the panels you will see a slide bar (Image 76.1). Slide "UP" for a "COOLER" temperature and slide "DOWN" for a "WARMER" temperature.
NOTE: On some models, you can select "TEMP SET" on the refrigerator control panel for some models.
SHUT DOWN: Push the "ON/OFF" button for two seconds.
The refrigerators in some motorhomes have a resettable thermostat. To see if your refrigerator model has this feature, please refer to the manufacturers appliance manual or visit the corporate website for literature regarding your refrigerator model.
TROUBLESHOOTING THE REFRIGERATOR - LIQUID PROPANE (LP) GAS
If you are experiencing any problems with the refrigerator while using the liquid propane (LP) gas mode, please check the following items:
• The "ON" button must be in the "IN" position. • The "AUTO/MANUAL" button must be in the "OUT" position.
• The liquid propae (LP) gas tank must have liquid propane (LP) gas and the valve must be open. • The liquid propane (LP) gas detector must be "ON" and operational.
• The 12V supply must be operational and charged. (NOTE: this can be checked at the monitor panel).
• The motorhome should be parked on the best level ground as possible.
• There may be air in the liquid propane (LP) gas line. Cycle the refrigerator "ON" and "OFF" several times, waiting 30 seconds between cycles.
NOTE: A refrigerator can take up to six hours to cool down after initial start up or with extended periods of being opened and closed.
TROUBLESHOOTING THE REFRIGERATOR - 120-V
If you are experiencing any problems with the refrigerator while using 120-V, please check the following items:
• The "ON" button must be in the "IN" position. • The "AUTO/MANUAL" button must be in the "IN" position.
• Is the microwave clock "ON"? If so then the 120-V system is working and you should check the breaker for the refrigerator in the converter.
• If the microwave clock is not on, then you should troubleshoot the 120-V system.
• The motorhome should be parked on the best level ground as possible.
NOTE: A refrigerator can take up to six hours to cool down after initial start up or with extended periods of being opened and closed.
Stovetop (Range)
HOW IT OPERATES:
The stove-top burners (Image 78.1) are operated on liquid propane (LP) gas. The operation is the same as a gas stove in a house, but unlike a home the amount of oxygen is limited in a motorhome due to the size and construction.
Therefore, always have sufficient ventilation when using the stove. There is an exhaust fan located in the hood (Image 78.2) above the stove-top that may be used during cooking for extra ventilation.
USING THE STOVE-TOP
Your motorhomes stove-top has an igniter knob (type will vary depending on stove-top model).You should light tthe stove with the igniter knob rather than with a match.
USING THE IGNITER KNOB
1. Turn the valve at the liquid propane (LP) gas tank counterclockwise to its fully opened position. (The liquid propane (LP) gas detector must be in the "ON" position and the green light blinking).
2. Push in and turn the desired knob to the desired position.
3. Turn or push the igniter knob (Depending on stove-top model). This will cause a spark which will ignite the flame. If the stove will not light, turn the burner knob to the "OFF" position to stop the flow of liquid propane (LP) gas. You may then try using a match.
4. Once lighted, adjust the flame to the desired level.
The Furnace
HOW IT OPERATES
Use the wall mounted thermostat (Image 80.1) to turn the furnace on. Air is heated by burning liquid propane (LP) gas. A blower using 12V power from the coach battery(ies) circulates the hot air through the motorhome.
NOTE: If the chassis battery(ies) are not being charged via the chassis engine, a campground connection or the generator, the furnace blower will will discharge the power supply in about two to three hours and then the furnace will shut off.
If this happens, you may recharge the battery(ies) by running the chassis engine, generator or campground connection. Charging by the chassis engine or the on-board generator will replenish your battery(ies) to sufficient power in approximately forty five minutes.
FURNACE START UP
• Verify that the liquid propane (LP) gas is turned on in the full open position and that the liquid propane (LP) gas detector is "ON" and the green light is flashing.
• Move temperature selector on the wall thermostat to its highest position.
• Allow three to four minutes after the blower motor starts for the air to heat up. The ducts are located near the floor throughout the motorhome.
• Adjust thermostat to the desired temperature setting
TROUBLESHOOTING THE FURNACE
Water Heater
Your motorhome is equipped with a liquid propane (LP) gas water heater. The water heater "ON/OFF" switch is located on the monitor panel (Image 82.1) next to the generator start button.
The water heater has a six gallon capacity for water. The water is supplied from two different sources; campground water supply via a fresh water spigot through a water hose connected to the fresh water connection of your motorhome or a supply of fresh water carried on-board in your fresh water tank. To obtain fresh water from your onboard tank, you must turn on your water pump by turning on the switch located on your control panel (Image 82.1). Refer to manufacturers literature for further information.
The water is heated by burning liquid propane (LP) gas. This is supplied from your liquid propane (LP) gas tank located on the lower exterior of your motorhome. NOTE: If you are running low on liquid propane (LP) gas, the water heater will not operate.
Additionally, the water heater will not operate if there is insufficient electrical voltage in the 12V system to produce a spark to light and maintain the water heater pilot light.
Electronic ignition provides convenience and safety. The water heater is turned "ON" or "OFF" with the control switch on the monitor panel.
The water heater pilot indicator light should come on briefly (up to five seconds) when the control switch is flipped "ON". If the light does not come or stays on too long, see the troubleshooting chart.
Water should be sufficiently hot for bathing in about twenty minutes.
