Exhaust Duct Via The Roof (Akd Cowl Kit); Combustion Air Intake Installation; Installing The Roof Cowl; Exhaust Pipe Assembly - Truma S 2200 Operating Instructions Manual

Exhaust duct via the roof (AKD cowl kit)

Only Truma stainless steel exhaust duct AE 3 may be
used with the S 2200 (P) (part no. 30140-00) with the Truma
insulating duct ÜR (APP – part no. 40230-00), since the heater
has only been tested and approved in combination with these
pipes. Maximum length of exhaust pipe 300 cm.

Combustion air intake installation

1. Fig. D1
Undo the two screws (1) on top of the heater and remove the
casing.
2. Fig. D2
Before installing the heater, fit duct manifold for combustion
air intake to lower heater connection as follows: Slide duct
manifold (18) with cut edge of duct through hole (19) in heat-
er pedestal from below. Slide sealing plate (4) onto duct by
about 3 cm (claw points towards heater connection). Carefully
guide O-ring (5) over cut edge of duct by expanding it and
insert duct manifold into lower heater connection (9) as far as
it will go. Slide sealing plate with O-ring in as far as it will go
and secure by rotating it. Tighten securely with screw (6).
A new O-ring (5) must be fitted whenever the
exhaust pipe has been removed.
3. Place heater in floor opening.

Installing the roof cowl

The roof cowl must always be installed vertically or with a
maximum incline of 15 degrees!
Fig. D3
Position roof cowl such that a duct can be directly routed
from the heater to the cowl ascending along its entire length
(max. 300 cm). A height of at least 100 cm must be reached
with a duct length of 150 cm.
1. Fig. D4
Cut Ø 60 mm + 1 mm opening in a central position, approx.
55 mm from the side walls. If the roof has a double layer, line
cavity with suitable heat-resistant material (21) to stiffen roof
so that it is not deformed when the screws are tightened and
remains watertight.
2. Insert cowl through roof from above and tighten from
inside with screwing ring (22). Secure screwing ring with
screw (23).
The pipe is sealed by the provided rubber seal – no additional
sealing required.

Exhaust pipe assembly

1. Fig. D5
Slide flow control plate (20) into upper heater connection (3)
as far as it will go.
2. Connect exhaust pipe (2) to top heater connection (3) as
follows: Slide sealing plate (4) onto exhaust pipe by about
3 cm (claw points towards heater connection). Carefully guide
O-ring (5) over cut edge of duct by expanding it and insert
exhaust pipe into upper heater connection as far as it will go.
Slide on sealing plate with O-ring and secure by rotating it.
Tighten securely with screw (6).
A new O-ring (5) must be fitted whenever the ex-
haust pipe has been removed.
3. Slide insulating duct (7) onto exhaust pipe (must extend
from cowl to heater).

4. Fig. D4
Route ducts upwards against the wall with as little bending as
possible. Slide exhaust pipe (24) into cowl as far as it will go
and secure with sheet metal screw (25).
The exhaust pipe (24) with insulating duct (26)
must be ascending along its entire length and se-
curely and permanently installed using several clamps (27),
since otherwise a water pocket may form that will pre-
vent the exhaust gas from exiting freely.

Attaching the heater

Fig. E1
Secure heater to floor of vehicle with the 4 provided sheet
metal screws (28) through the heater pedestal. Fit heater cas-
ing (with rear wall if necessary) (break out breakthroughs for
ducts in cover or rear wall). Tighten screws (1).
Fig. E2
The rear wall with heat conducting plate (29) must be inserted
if the heat radiation is to be led towards the front or if a fan is
being connected for warm air distribution.

Warm air distribution

Fig. A1
– EKM installation box
The Truma fan can be secured to the rear of the EKM installa-
tion box.
Fig. F / E2
Truma fans (TEB-..., TN-..., TEN-...) or Multivent fans are suit-
able for warm air distribution. The Truma fans can be directly
attached to the rear wall (RWS or RWSL with heat conducting
plate) or separate from the heater on the floor or to the wall of
the vehicle. With floor / wall installation the DT air intake noz-
zle (part no. 40660-00) and pipe I 80 (Ø 85 mm) are needed.
The Multivent fan can be attached to the floor or the wall of
the vehicle near the heater. To do this, use air intake nozzle
DM (part no. 40670-00) and pipe ÜR (Ø 65 mm)
The Truma accessories for warm air distribution are available
for expanding the warm air system – please ask your dealer.

Gas connection

The operating pressure of the gas supply (30 mbar)
must be the same as the operating pressure of the de-
vice (see type plate).
The Ø 8 mm gas supply pipe must be attached to the connec-
tor with a cutting ring screw fitting. Carefully counterhold with
another wrench when tightening!
The gas connection on the device may not be shortened
or bent.
Before connecting to the device, please ensure that the gas
lines are free of dirt, shavings and the like!
The duct routing must make it possible for the device to be
removed again for service work.
The number of separation points in the gas supply line in
rooms used by persons must be limited to the technical
minimum.
The gas system must comply with the technical and admin-
istrative regulations of the respective country of use (e.g.
EN 1949 for vehicles in Europe).
The national legislation and regulations (e.g. DVGW Work
Sheet G 607 for vehicles in Germany) must be observed.
