Exhaust Gas Cowl; Trumatic S 3002 (P); Connecting The Exhaust Duct To The Heater; Gas Connection - Truma Trumatic S 3002 P Installation Instructions Manual

2. Fig A: Remove automatic ignitor (15) from its holder.
Fasten the heater by means of the 5 screws (3 – holes are
pre-punched in the corners and front centre). If necessary,
reinforce the floor structure with battens.
3. Check the automatic ignition device (15) to ensure that the
plug-in connections (13 + 14) are mounted properly. Then
push the automatic ignition device (15) into the link plates (16)
as far as the stop (fig. A shows right-hand installation, fig. G
shows left-hand installation).
4. Fig. A: Insert push rod with eye spring (11) into ignition
safety valve (12). Insert control knob (55) onto push rod (11)
so that the arrow points to "0" (heater middle position).

Exhaust gas cowl

The heater is only approved when used with a roof cowl.
This must be installed vertically or with no more than a
15 degree slope!
Fig. F: Position the roof cowl so that the duct (minimum
length 1.5 m, maximum length 3 m) can be routed direct
from the heater unit, sloping upward all the way to the cowl.
A 1.5 metre long duct must reach a height of at least 1 metre.
The remain der of the duct to the roof cowl must be installed
more or less vertically.

Trumatic S 3002 (P)

Fig. E: Cut out an opening with a Ø of 60 mm at a centre dis-
tance of at least 55 mm from the side walls.
Trumatic S 5002
1. Fig. E: Cut out an opening with a Ø of 70 mm at a centre
distance of at least 60 mm from the side walls.
2 Fig. E: In the case of a double-skin roof, line the cavity with
wood or slide in a rolled circular sheet metal strip (20) of about
220 mm in length and 1 mm in thick ness, to stiffen the roof so
that when the screws are tightened it does not warp and stays
weatherproof.
3. Fig. E: Push the cowl through the roof from above and
fasten it on the inside with screw ring (21). Next, secure the
screw ring (21) with a screw (44).
Use the enclosed rubber sealing ring without further sealing
materials.
Exhaust duct
For the Trumatic S, only the Truma stainless-steel waste gas
pipe AE 3 or AE 5 with the Truma pipe sheath UR or UR 5 (APP)
may be used, since the devices have only been tested and ap-
proved in conjunction with these pipes.
Length of exhaust duct: min. 1.5 m, max. 3 m!
Fitting and bending the stainless steel duct and stretching
open the O-ring are made considerably easier by using
"Biege-Boy" (part no. 30030-33000).

1. Connecting the exhaust duct to the heater:

Slide sealing plate (22) about 3 cm onto the exhaust duct
(with the claw pointing towards the heater exhaust outlet).
Slide on pressure ring (25). Stretch open O-Ring (23) and
carefully pass it over the cut edge of the duct. Then plug the
exhaust duct into the exhaust outlet as far as the stop.
Slide the O-ring, pressure ring and sealing plate to the exhaust
outlet. Twist on sealing plate (22) and fasten it securely by
tightening screw (24).
A new O-ring (23) must be fitted each time the
exhaust duct is dismantled.
2. Slide insulating duct (41) onto the exhaust duct (it must
reach from the cowl to the rear wall of the installation box,
refer to fig. E + D).
3. Fig. D + E: Take the ducting up the wall with as few bends
as possible. Slide exhaust gas duct (40) into the cowl as far as
the stop and secure with self-tapping screw (28).
The flue gas pipe (40) with insulating duct (41)
must be ascending along its entire length and
securely and permanently installed using several
clamps (42), since otherwise a water pocket may form
that will prevent the flue gas from exiting freely.

Gas connection

Fig. A (e): The gas supply's operating pressure (30 mbar)
must be the same as the unit´s operating pressure (see type
plate).
Fig. G: The gas supply pipe (32) must be connected using a
cutting ring screw fitting with an outer diameter of 8 mm at
the connecting piece (33).
The gas connection fitting on the heating appli-
ance must not be bent! When tightening the connec-
tion nipple, hold it carefully in place with a second wrench!
Route the ducting in such a way that the heater can be re-
moved for servicing work.
Make sure the gas lines are free of dirt, chips and such prior
to connecting!
A special duct for internal gas connection is available on re-
quest. It is screwed onto gas connection fitting (33) with an
elbow.
The gas system must accord with the technical and adminis-
trative provisions of the individual country of use (in Europe,
for example, EN 1949 for motor vehicles).
National regulations and rulings (in Germany, for example,
the DVGW worksheet G 607 for motor vehicles) must be
respected.
