Things to note before Installation
Heater installation
Country specific regulations shall be followed in any installation. The warranty of products is valid only in installations
that are done according to this manual. Wallas recommends that the device be installed by an authorized Wallas
service shop or professional installer.
Selecting the installation location
The device shall be installed into a dry space in a protected location. The device must be mounted to a solid surface.
When installing, please note that the device needs to be removable for servicing. Connections and location should be
made so that the device can be easily disconnected for removal.
The heater should be installed vertically level when the boat is on an even keel. The static inclination must not exceed
5°. While the device will tolerate being temporarily tilted to a steep angle (even for some hours), the burner will not yield
optimal performance if it is constantly inclined.
Select the place of installation to allow a minimum amount of bending in the hoses / ducting. Avoid installing the heater
and control panel in the immediate vicinity of any potential water intrusion. If possible, install the control panel on a
vertical surface.
Installation of pipes, hoses and cables
Power cables, water and fuel hoses must be protected in locations where they are susceptible to mechanical damage
due to sharp edges or heat. All cables and hoses should have a fluid precluding "drip loop" to prevent water or other
fluids from following wires or hoses to the heater. All cables should be strained.
Installation of valves
A separate mixing valve must be installed to the hot water line if Wallas on-demand hot water accumulator is used
because Wallas on-demand hot water accumulator doesn't have a mixing valve built-in.
Installation space
The device can be installed within the heated space or outside of it. The device should be protected from rain and
splash water.
It's forbidden to install the heater to a space which may contain gasoline fumes!
When designing or installing the system, make sure that any possible leakage points (joints, the whole heater
and the expansion tank) are installed in such a place that the possible leaks cannot destroy anything. It is
recommended to build a spill reservoir which can hold the coolant used in the system.
Following sections of manual are presenting important basic installation information but if you have any questions
please be free to contact purchasing/local distributor point for more information.
