Waste Tank; Water Heater - Thor Motor Coach 2011 Avanti Owner's Manual

• Antenna not pointed in direction of sending station. Point antenna in proper
direction.
• Cut or torn cable. Have a Thor Motor Coach dealer or a qualified RV technician replace
bad cable where needed at TV and antenna.

• The rotate handle is engaged to the ceiling plate. Pull down on handle to disengage
from the ceiling plate.
• Possible obstruction (tree branch, etc.). Remove obstruction.
• Friction adjustment. Adjust center lock nut.
• Design of antenna limits rotation to 350°. Adjust as necessary.
Waste tank (black) will not drain.
• Buildup or debris in tank. Check for buildup in tank at stool.
• Always use a minimum amount of biodegradable toilet paper.
• Always use plenty of water when flushing.
• Check termination valve for proper operation.
Temperature-pressure relief valve weeping.
• Weeping or dripping of relief valve while water heater is running does NOT
mean it is faulty.
There is an odor that smells like rotten eggs.
• If your fresh water source has a rotten egg odor, you will need to find another source
of fresh water before flushing and refilling the entire RV water storage system. To
remove the hydrogen sulfide (rotten egg) odor:
• Turn off your main water supply; that is your pump or your water hookup source.
• Drain your water heater tank by removing the drain plug. Approximately two quarts
of water will remain in the bottom of the tank. If you notice during the draining that
the water is flowing sporadically or slowly, instead of flowing freely, you should open
your relief valve to allow air into the tank.
• If the water does not flow freely, take a small gauge wire or coat hanger and push
through the drain opening to eliminate any obstructions.
• After thoroughly draining the tank, flush the entire system from the water inlet all the
way to the holding tank. To flush, use four parts of vinegar mixed with two parts of
water. If you decide to use air pressure ( 55 PSI max.), it may be applied either through
the inlet or outlet on the rear of the tank. It may also be applied through the relief
valve port. In this case, it will be necessary to first remove the relief valve. You may
then insert your air pressure through the relief valve support flange. In either case,
with the drain valve open, the air pressure will force the remaining water out of the
tank. If air pressure is unavailable, you may flush your tank with fresh water. Fresh
water should be pumped into the tank with the assistance of the on board water
pump or with the assistance of external water pressure. Once again, external pressure
may be pumped into the unit either through the inlet or outlet found on the rear of
the water tank, or using the relief valve inlet located on the front of the unit.
• Continue this flushing process for approximately five (5) minutes allowing ample
time for the fresh water to agitate the stagnant water on the bottom of the tank and
