Combustion Gases Outlet; Refrigeration Installation - Thetford N80 Installation Manual

5. EXTRACTION OF COMBUSTION GASES
- The air for the burner must not come from the living area of the caravan or motor home
and combustion gases must not enter the living area. The refrigerator must therefore be
installed in a place completely separated (insulated) from the living area of the caravan or
motor home.
- The fully installed refrigerator must allow the proper and complete discharge of
combustion gases. Combustion gases may contain carbon monoxide. Inhalation of this
gas may cause tightness of the chest, dizziness and can lead to death.
-
The refrigerator is designed for powering by liquid propane gas, butane gas or a mixture.
- A qualified person must install gas components.
- The gas components must be installed in accordance with the latest technical regulations.
- Combustion gases must always be discharged upwards.
- The exhaust of the refrigerator must be installed so that it is always accessible for
maintenance and repairs.
5.1 Installing the flue exhaust system
FIGURE 9: The flue cap [E] has to be assembled together with the vent frame [A]. The exhaust
9.
tube [F] takes care of transporting the exhaust fumes and created heat outside the combust ion area.
The outlet of the exhaust tube has to be close to the bottom-side of the vent . By rotating (see arrows)
the exhaust tube and sliding it over the flue [G] you can adjust it so that the outlet of the exhaust is
in the position as shown in the drawing below .
- It is important to always keep a distance of 5mm minimum from the vent!
- The outlet of the exhaust tube has to be close to the bottom-side of the vent.
- When positioned correctly, use the clamp to fix the exhaust tube to the flue of the
refrigerator.
For refrigerator model N145 only:
You do not need to install a separate extractor. The combustion gases will automatically be extracted
properly via the upper ventilation grating after installation of the refrigerator.
FIGURE 10: Check that the minimum distance between the cover and the sides of the caravan or
10.
motor home is at least 1 cm. Make sure that the closed side of the cover faces the refrigerator.
6. INSTALLING THE REFRIGERATOR
- The air from the burner must not come from the living area of the caravan or motor home
and combustion gases must not enter the living area. The refrigerator must be installed in
a place completely separated (insulated) from the living area of the caravan or motor
home.
- The performance of the refrigerator is affected by the way it is installed.
- The performance of the refrigerator may be affected by adjacent heat sources such as an
oven or stove. Protect the refrigerator against any adjacent heat source by fitting
insulation.
- Make sure the floor is solid and even. The floor must be able to take the weight of the
refrigerator with its contents.
