March 15, 2025
To adjust the mirrors on a 2015 Tiffin Allegro: 1. Adjust the convex mirrors so that 1/3 of the mirror shows your motorhome and the rest shows vehicles alongside. 2. Adjust the mirrors vertically to improve visibility. 3. Use the mirror adjustment controls to fine-tune the position. 4. Further adjustments can be made at the swivel portion of the mirror arm. 5. The mirrors contain heating elements for defogging or de-icing, controlled by a red "on/off" switch near the adjustment controls. 6. Be aware that objects in convex mirrors appear smaller and farther away than they actually are.

What could be draining our house batteries in our 2015 45LP Allegro Bus when we are plugged into a 50 amp service
1 comments:
Mr. Anderson
March 1, 2025
Possible causes of house battery drain in a 2015 Tiffin Allegro Bus 45LP while plugged into a 50-amp service include:
1. 12 VDC Loads – Interior lights, water heater, TV switching box, slideouts, power roof vents, and the monitor panel continue to draw power from the house batteries. 2. Inverter Usage – If the inverter is supplying power to appliances, it may be drawing from the batteries. 3. Faulty Converter or Charger – If the converter or battery charger is not functioning properly, the batteries may not be charging while connected to shore power. 4. Battery Disconnect Not Engaged – If the battery disconnect switch is off or malfunctioning, the charging system may not be supplying power to the batteries. 5. Parasitic Draws – Devices like radios, satellite receivers, and personal computers may continue to draw power even when not in use. 6. Battery Condition – Aging or damaged batteries may not hold a charge properly, causing them to drain quickly. 7. Loose or Corroded Connections – Poor electrical connections can prevent proper charging and lead to battery drain.
Checking the converter, inverter, battery connections, and loads on the 12 VDC system would help diagnose the issue.

GENERAL INFORMATION SAFETY MESSAGES Please note that several labels listed in this manual represent items that need your attention. The Dan- ger, Warning, Caution, and Notice labels alert you to precautions that may help you avoid damage to your motorhome, its equipment or your personal safety. Please read and follow them carefully. N OT I C E NOTICE is used to address practices not re- lated to personal injury.
SAFETY SAFETY CONSIDERATIONS Prior to using your motorhome, especially for the first time or after a long period of non-use, please read thoroughly all the instructions in the Owner’s Manual and the chassis-manufacturer’s manual be- fore attempting to operate your motorhome. There are several safety considerations which you should realize and follow while your Allegro is in motion.
SAFETY YOUR PRE-DEPARTURE CHECKLIST For your continued safety and convenience, the following is a representative “check list” designed to assure your safety while driving: √ Clean all windows, mirrors, and light lenses (front, back, side) to assure that you can “see” and “be seen. ” Reposition any mirrors other fixtures to provide an unobstructed view (front, sides, and back) from the driver’s seat.
SAFETY DRIVING SAFETY Various adjustments need to be made to assure the driver’s comfort and the safety of the motorhome before starting and moving the motorhome; these in- clude: • Do not attempt to ad- just the driver’s seat while the vehicle is moving.
SAFETY FUELS FOR THE MOTORHOME W ARNING Liquid propane (LP) gas containers, gasoline, or other flammable liquids are not to be placed or stored inside the motorhome because a fire or explosion may occur. LP gas containers (Figure 2-2) are equipped with safety valves that may relieve excess pressure by discharging gas into the atmosphere—any containment of that vent- Figure 2-2: LP tank...
SAFETY LIQUID PROPANE (LP) GAS SYSTEM Check the propane gas system for leaks yearly or as necessary. If you smell gas within the motorhome, quickly perform the following: IF YOU SMELL PROPANE • Extinguish any open flames, pilot lights and all smoking materials. •...
Page 23
SAFETY The liquid, when it passes through the tank valve to a lower pressure, vaporizes into a gas, and then passes through a regulator to maintain a constant pressure. This gas, then, is the actual fuel distributed through the LP-gas manifold system to the LP-based appliances used in your motorhome. LP-appliance lighting problems are typically caused by an improperly-adjusted gas regulator.
SAFETY LP GAS REGULATOR The LP gas regulator (Figure 2-4) is the most critical element of the LP-gas distribution sys- tem. The regulator converts the high-pressure LP gas from the tank into a reduced-pressure LP-gas supply suitable for use in the various appliances in the motorhome.
SAFETY RECOMMENDED CARBON MONOXIDE WARNING PRACTICES WA RN ING The following practices are recom- mended to assure continued safety and reliability of the LP gas system. These are, of course, representative; Avoid inhaling exhaust gases as they con- not necessarily exhaustive. In all tain carbon monoxide, which is a colorless, cases, use common sense in the use odorless and poisonous gas.
SAFETY CO/LP GAS DETECTOR Since LP gas is more dense than air, the LP gas will naturally settle to the lowest point in an enclosed space. In the motor- home, this would be the oor. Because of this, the CO/LP gas detector (Figure 2-6) is neces- Figure 2-6: sarily mounted close...
Page 27
SAFETY senior citizens, and people with cardiovascular or respiratory problems. Consequently, it is prudent to check the CO monitor regularly for normal operation and to remain aware of the symptoms of CO poisoning which include dizziness, nausea, vomiting, muscular twitch- ing, throbbing in the temples, incoherent thinking and speech, weakness, sleepiness, and intense head- aches.
Tiffin Motorhomes has taken every precaution and design practice to minimize or negate this possibil- ity, but the final determination rests with the owner and user of the motorhome.
SAFETY SMOKE DETECTOR The Allegro motorhome is equipped with a battery-op- erated smoke detector (Figure 2-8) located on the ceil- ing in the living area of the motorhome. The smoke detector should be tested on a weekly basis, before each trip, and after any period of storage of the motorhome.
SAFETY EMERGENCY EXITS In the living areas of the motorhome, there are emer- gency exit windows (Figure 2-9 and 2-10). These win- dows are designed for emergency exits when it is not practical to exit by the door, which also is an emergency exit - in the front of the motorhome.
SAFETY “on” the LP gas valve at the LP tank. Connect the fresh-water supply and sanitize the water systems as needed. Connect the waste drain hose to the external sewer hook-up. Start the refrigerator, water heater, and furnace; as warranted. Light the oven pilot light, as needed. Certain appliances, such as the refrigerator, will not work properly, if the motorhome is not level, so be sure to complete the motor- home-leveling process before activating any of the appliances.
HEATING & AIR CONDITIONING FURNACE NOT ICE NEVER attempt to modify the furnace. To do so may cause fire, explosion, carbon monoxide poisoning or asphyxiation. If the furnace is malfunction- ing, immediately shut the unit “off” and call a trained service technician as soon as possible.
Page 34
HEATING & AIR CONDITIONING To shut down the furnace, turn the thermostat to the “off ” position. Even though the thermostat may be turned “off, ” the furnace system will continue to run for about a minute or so to permit a gradual cool-down of the heating system which is normal.
HEATING & AIR CONDITIONING AIR CONDITIONING SYSTEM The factory-installed air-conditioning system is designed for 120 VAC power supplied either from the external power cord or from the generator. For the best cooling scenarios, park the motorhome in a shady location whenever possible and close drapes on those windows exposed to direct sunlight. The air-conditioned, cooled air is emitted through the vents which are located in the roof throughout the entire coach along the passenger side.
HEATING & AIR CONDITIONING THERMOSTAT CONTROLS The following is a brief overview of how best to use the thermostat (Figure 3-5). For more detailed instructions, please consult the ther- mostat literature in the Owner’s Information Package. 1. Use the “Thermostat” switch to select the de- sired function (e.g., COOL, OFF, GAS HEAT, or ELEC HEAT).
LP GAS SYSTEM LIQUID PROPANE (LP) TANK The Allegro is equipped with an ASME (American Society of Mechanical Engineers)-approved LP tank (Figure 4-1) which is equipped with an automatic pressure regulator. This tank contains liquid petro- leum fuel under high pressure. A LP gas-distribution system distributes the gas to those appliances using such in the motorhome.
LP GAS SYSTEM N OTIC E If a gas leak is noted or suspected, turn “off” the main valve and keep the LP gas system “off” until that system is inspected by a qualified service techni- cian as soon as possible. Do not delay in addressing any possible gas leaks with appropriate service because of the inherent hazards to safety.
Page 40
LP GAS SYSTEM NOT ICE When a LP gas regulator is installed or re-installed, the regulator must al- ways be installed with the gas diaphragm vent facing downwards. For more information, consult the manufacturer’s literature in your Owner’s Informa- tion Package that came with the motorhome. Always keep the main valve to the LP gas tank closed when the system is not in use.
APPLIANCES & ACCESSORIES LP/GAS REFRIGERATOR Your coach may be equipped with a standard LP/gas refrigerator. When this refrigerator is in the “LP gas” mode, make sure that the main LP gas valve is in the “on” position before attempting to start the refrigera- tor.
APPLIANCES & ACCESSORIES RESIDENTIAL REFRIGERATOR Some coaches contain the optional 110-volt style resi- dential refrigerator which is powered from an outside source or from the unit’s generator or inverter which uses a 12 volt battery power supply. This unit operates as most home refrigerators do. NOTE: While traveling, the refrigerator will be pow- ered by the inverter.
APPLIANCES & ACCESSORIES MICROWAVE OVEN The Allegro contains either a microwave oven or an optional convection micro- wave (Figure 5-4). All microwave ranges operate on 120-volt AC electrical power, supplied either by the external electrical hookup or by the onboard electrical gen- erator in the motorhome.
APPLIANCES & ACCESSORIES OVEN AND OPTIONAL COOK TOP The Allegro may be equipped with a stan- dard recessed three burner range or it may have an optional, three-burner, recessed cook top (Figure 5-6). The oven may have a piezoelectric ignition source, rather than a pilot light, to start the oven.
Page 46
APPLIANCES & ACCESSORIES DA N G E R All LP gas-operated appliances in the motorhome will consume oxygen. If the motorhome is totally closed during such operation, the oxygen level may be reduced and the associated carbon monoxide level may be increased thereby causing possible harm or death to the occupants through asphyxiation.
APPLIANCES & ACCESSORIES WATER HEATER WA RNIN G DO NOT APPLY 110 VAC POWER to or LIGHT the water heater until after the water heater is filled with water and the water lines and heater tank are purged of any trapped air. Failure to do so will damage the water heater and may cause additional damage to the motorhome.

ROUTINE MAINTENANCE For motorhomes, the water and propane also need to be considered. The weight of fully filled pro- pane containers is considered part of the weight of the RV before it is loaded with people or cargo and is not considered part of the disposable cargo load. Water, however, is a cargo weight and is treated as such.

ROUTINE MAINTENANCE You can fi nd various places that have certifi ed public scales where your motorhome can be weighed. For example, moving and storage company lots, farm suppliers with grain elevators, gravel pits, recycling companies, and large-scale commercial-truck stops are some of the possible locations for weighing the motorhome.

ROUTINE MAINTENANCE stems and prevent air from escaping from the valve stems. Tire Wear, Balance, and Wheel Alignment In addition to tire inflation considerations, the tires should also be periodically examined for other types of normal “wear and tear. ” If installed and maintained properly, all tires mounted on the motor home should wear in a smooth, even pattern.
Normal deterioration of the appearance of such items caused by wear and/or exposure to strong lighting is not covered by the Tiffin Motorhomes Limited Warranty. Carpet A weekly routine of vacuuming the carpet and fabrics throughout the vehicle is recommended. The optional vacuum system has a central connection within the motorhome wherein a vacuum hose can be connected and the necessary vacuuming performed, as desired.
For further instructions to change the dust bag, use the attachments, and proper cleaning tech- nique, refer to the specific Owner’s Manual located in your motorhome. FABRICS The fabrics used in this Tiffin motorhome for the bed- spread, draperies, headboard, and valances contain fire-re- tardant additives that may be damaged by use of improper cleaning products.
These stains should receive immediate, professional attention. Spills, spots, stains, or soiled areas are the responsibility of the owner and are not covered by Tiffin Motorhomes Limited Warranty. Figure 16-7: Bedroom fabrics WARN IN G...
Additionally, since heat-producing appliances can also damage countertop seams, it is essential to check with Tiffin Motorhomes to identify seam locations to avoid them during subsequent use of the motorhome. Although solidsurfacing is repaired easily, certain steps should be taken to protect it.
ROUTINE MAINTENANCE Be sure to use a cutting board, rather than cutting directly on the countertop surfaces. Although minor scratches and cuts can be repaired, a little care will assure that the counter- top surfaces will keep looking new for years. Avoid using harsh chemicals on the countertop.
Always follow the chassis maintenance guidelines found in the chassis manufacturer’s owner’s manual. All routine maintenance is the responsibility of the owner and is not covered by the Tiffin Motor- homes Limited Warranty. Use the maintenance record found in Chapter 15 to record all performed maintenance as required.
• Check, clean, and tighten battery cables and inspect batteries for proper fluid levels. Every Six Months • Inspect the slide-out for proper seal. If realignment is necessary, please contact an authorized Tiffin Motorhomes Service Center. • Inspect the exterior rubber slide-out seals and apply an UV inhibitor, such as 303 Pro tectant.
4. Place the other end of the hose into a gallon of freshwater system antifreeze (one can refer to the local Tiffin Motorhomes dealer or representative for the freshwater antifreeze formu lation for your specific area). NOTE: Do not use automotive antifreeze; use only antifreeze approved for RV applications.

What could be draining our house batteries in our 2015 45LP Allegro Bus when we are plugged into a 50 amp service
Possible causes of house battery drain in a 2015 Tiffin Allegro Bus 45LP while plugged into a 50-amp service include:
1. 12 VDC Loads – Interior lights, water heater, TV switching box, slideouts, power roof vents, and the monitor panel continue to draw power from the house batteries.
2. Inverter Usage – If the inverter is supplying power to appliances, it may be drawing from the batteries.
3. Faulty Converter or Charger – If the converter or battery charger is not functioning properly, the batteries may not be charging while connected to shore power.
4. Battery Disconnect Not Engaged – If the battery disconnect switch is off or malfunctioning, the charging system may not be supplying power to the batteries.
5. Parasitic Draws – Devices like radios, satellite receivers, and personal computers may continue to draw power even when not in use.
6. Battery Condition – Aging or damaged batteries may not hold a charge properly, causing them to drain quickly.
7. Loose or Corroded Connections – Poor electrical connections can prevent proper charging and lead to battery drain.
Checking the converter, inverter, battery connections, and loads on the 12 VDC system would help diagnose the issue.
