Under-floor assembly with wall cowl kit

Refer to installation variant Fig. 4 (page 2).
Cowls must always be fitted to prevent any waste gases en-
tering the inside of the vehicle. The waste gas must always be
guided to at least a side wall (see "Choice of location").

Fastening the heating appliance

Assemble with the aid of the
asembly mount. Fasten both
mounts (36) securely and firmly to
the vehicle with through bolts not
less than M5 in size. Fasten the
U-beam (37) to the outside of the
heater with the bolts supplied (38).
Fasten the heater with 4 M6 x 10
bolts (39) and self-locking nuts.
Fasten two protective caps (40) to
the outside of the vehicle.
In order to drain condensation water, drill a hole 8 mm in di-
ameter at the lowest point in the heater casing some 20 mm
from the edge. Ensure that the drill does not penetrate more
than 10 mm in order to prevent damage to any internal com-
ponents. Insert the rubber grommet (d) supplied (it extends
about 4 cm downwards).

Outside assembly with cowl pipes

See installation variant Picture 3 (page 2) and the Truma as-
sembly instructions "Additional truck heating systems" and
"Trunk compartment heating system E 4000 A".
Fastening the heating appliance
Inside installation with wall cowl or roof cowl
Depending on the installation site, bolt the heating appli-
ance securely with the fastening straps (a) or angle pieces (b)
supplied.

Warm air distribution and circulating air
return with interior installation
Warm air distribution
Warm air suction apertures must be arranged in such a way
that no exhaust gases from the engine or the heating device
can be drawn in. It must be ensured by means of construction
design that the heating air introduced into the vehicle is not
polluted (e.g. by oil vapour). This is achieved, for example,
with air heaters with circulating air operation, both for interior
installations and for external installations. (In heaters with
fresh air operation the fresh air is not to come from the engine
compartment, from the vicinity of the exhaust or the exhaust
outlet of the heater.)
The warm air (W) is expelled from
2 vents, either directly or via a
warm air duct VR 72 (diameter
72 mm).
From the appliance to the first air outlet install only VR 72 duct
(72 mm diameter) with a maximum length of approx. 1.5 m.
To prevent overheating, the first air outlet must be non-
sealable (swivelling vent SCW 2, end support EN-O). ÜR duct
65 mm diameter) can also be laid after the first air outlet. Hot
air ducts whose surface temperature exceeds 80 °C (especially
as far as the first air outlet in the case of the E 4000) must be
protected from contact by cladding with a duct insulator (such
as Truma l 80). Secure all duct connections with self-tapping
screws. Fasten ducts with clamps.
The warm air system is designed for each type of vehicle indi-
vidually, on a modular basis. There is an extensive accessories
program available (refer to brochure). Diagrams with optimum
installation suggestions for warm air systems in all of the most
popular motor home models can be requested free of charge
via the Truma service centre.
Circulating air return
The circulating air (U) is sucked directly back into the appliance.
If the heating appliance is installed in a stowage compartment
or similar, make an appropriately sized opening (approx, 200 cm
for circulating air feedback.
Do not block air ducts to heating appliance!
Warm air supply and circulating air return
with outside assembly
Refer to installation variants Fig. 3 + 4 (Page 2).
The warm air duct and recirculating air duct between the
heater and the vehicle – especially in the area prone to stone
demage – must be made from flexible LF air ducting or, in the
protection zone, from LI air ducting (106 mm in diameter).
A protective casing over the entire heater system protects it
against damage and weather conditions and simultaneously
serves as insulation.
