Installation
Heater installation
Country specific regulations shall be followed in any installation.
The warranty of boat products is valid only in boat installations. The warranty is not
valid in installations to vehicles or other spaces.
The device is meant for marine pleasure craft use. The device is not designed for
continuous use for example in live aboard boats or commercial settings. In such
use the device will require more frequent servicing not covered by warranty.
Things to note when 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, stable bulkhead or wall. Deck or floor mounting is not
possible with these models. 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. For maintenance, it is useful to
leave 200 mm (7
7
/
8
”) empty space below the heater for the removal of the bottom
cover of the heater.
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 warm
air 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 sur-
face. We recommend that the device be installed by an authorized Wallas service
shop or installer.
Things to note when installing pipes, hoses and cables
Power cables, warm-air ducting 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.
Installation space
The device can be installed within the heated space or outside of it. If located
outside the heated area, heating performance can be improved by installing the an
intake air tube to the heated space (warm return air). If located inside the heated
area, air refreshing performance can be improved by installing the an intake air
tube to the outside air (cold, dry fresh air to be heated).
The heater cannot be installed into a space which may include gasoline
fumes (danger of explosion).
