4. Make sure that the front edge of the opening is surrounded
by a solid frame to firmly anchor the appliance. If needed,
build an appropriate frame (Fig. 13) with the following di-
mensions:
Width a = 324 mm
Height b = 324 mm
Depth c = > 450 mm

• The required depth “c” depends on how the water
hoses, electrical connection cable, and gas line are
installed. The depth “c” must be determined for the
particular situation before installation.
• The corners of the rough opening must be at right
angles. The exterior wall opening must be the same
dimensions with no rounded corners.
• An access door adapter kit is available for replacing
existing water heaters, with a large cut-out in the
outer wall of the RV. The adapter plate must be
installed before the appliance is installed. The ac-
cess door adapter kit includes detailed installation
instructions.
5. Make sure you have suitable screws ready:
• Without access door adapter kit
In order to securely fasten the appliance and the cover plate,
the screws must be suitable for the chosen frame material
and have a diameter of 3.5 mm to 4.2 mm.
– Never use countersunk screws to secure the
cover plate, as it will be damaged (tear). Use pan head
screws.
– For the length of the screws follow the screw manufactur-
er’s guidelines.
• With access door adapter kit
You must use the 22 screws (4.2 x 13 mm) that are included
with the access door adapter kit.
– 14 x for fixing: appliance with adapter plate.
– 8 x for fixing: cover plate with adapter plate.
Preparing the gas connection
Risk of explosion due to improper installation of the
gas connection!
• Make sure that the operating pressure of the gas supply
corresponds to the operating pressure of the appliance
2.62 – 3.49 kPa.
For correct installation, you must also observe the
following:
• The gas connection (SAE 45° Flare Male – SAE J512,
5/8 inch – 18) is located inside the appliance.
• Make sure that the gas line to the appliance is able to sup-
ply the maximum required quantity of gas 61.9 MJ/h, with-
out the gas pressure on the gas connector of the appliance
falling below 2.62 kPa.
• Consider the space needed to lay the gas line and integrate
the appliance when planning the installation space.
• Guide the gas line into the installation space so that the ap-
pliance may be removed and reinstalled if service or repairs
are needed.
• Allow sufficient length and flexibility in the gas line for con-
nection or disconnection of the gas line.
• Reduce the number of separation points in the gas line to
the technically required number.
• Avoid separation points in the gas line in spaces used by
people.
• Ensure that the gas connection from the vehicle is in place
before installing the appliance.
– Gas side connection
Risk of explosion due to improper installation of the
gas side connection!
• Use rigid metal 3/8 inch pipes (corresponds to 1/2 inch
(12.7 mm) outside diameter) for the side gas connector of
the appliance to the gas system of the RV.
• In exceptions, flexible gas hoses may be used for the side
gas connector. The following 4 conditions must be met:
1. Guidelines, laws or regulations allow the use of flexible
gas hoses in this application.
2. The flexible gas hoses are
certified
for this type of
application.
3. The flexible gas hoses can be inspected easily over their
entire length.
4. New flexible gas hoses are used for the installation.
The gas line is guided into the appliance from the side. A hole
with a gas pipe grommet (side) is provided in the unit casing
for this purpose.
• Slide the appliance carefully into the installation space until
the installation frame makes contact.
• Make sure that the gas line connects vertically with the ap-
pliance’s gas connection and without tension.
• If the connection is OK, push the gas line back.
It will be connected in a later step.
