10. Installation
CAUTION Injury
Incorrect installation can result in severe injuries and
material losses.
Prior to installation ensure you have adequate space
for the work to be carried out.
Handle components with sharp edges carefully.
The sheet steel casing of the water heater is not
designed to withstand heavy forces.
Handle and install the water heater with care.
10.1 Installation location
DANGER Explosion
Never install the water heater in rooms where it is
at risk from explosions as a result of dust, gases or
vapors.
WARNING Injury
The room where the water heater is to be installed
must have a load-bearing floor. There is a risk of
the water heater breaking through the floor if the
substrate has insufficient load-bearing capacity. The
wet weight of the water heater is approx. 430 kg (950
lb).
If the floor offers inadequate load-bearing capacity,
there is a risk of the water heater breaking through
the floor, resulting in a risk to life.
Risk of frost damage
Install the water heater only in an area free from the
risk of frost. When the water heater is not in use and
there is a risk of frost, the water inside the water tank
can freeze and damage the tank.
- Never install the water heater in areas where the air
temperature regularly drops below 6 °C (42 °F) or rises above
42 °C (108 °F).
- To prevent nuisance through operating noise, never install
the water heater in the vicinity of bedrooms. Prevent noise
emissions towards a neighbor.
- Allow adequate space around the water heater for
installation, maintenance and cleaning tasks.
With internal installations, also observe the following:
- The available floor area in the installation room must be at
least 6 m² (10' x 10' - 100 ft²). The room volume must not be
less than 13 m³ (500 ft³).
- The water heater must not be restricted by walls and
ceilings. The required minimum clearances are specified in
chapter "Positioning the water heater/positioning conditions"
(see chapter 10.5, "Positioning the water heater")..
- Observe that the room temperature will drop by 1 to 3 °C (2
to 6 °F) as a result of the water heater operation.
- When installing the water heater in a furnace room, ensure
that the furnace operation will not be impaired.
- To keep line runs as short as possible, we recommend that
the water heater is installed near the kitchen or bathroom.
