WWH Heater
Pag. 5
The outlet grill can easily be taken off, turned around and replaced, to
direct the discharge in any desirable direction.
Attention: When replacing the grill, always use the same screws
(or screws of same length). A longer screw could pierce the
exchanger!
See to it that the discharge is not blocked and that the heater has a
free suck. Make sure that there’s sufficient circulation of air in the
room (enough ventilation) without the airstream being considered as
draft. Heaters suspended to the wall should always blow in direction
of the cold regions.

Water connections
Connections for hot water supply and return (two times ¾ inch or two times 1 inch) are marked with a
red and a blue sticker. Red is water supply and blue is water return. Do not twist these connections,
the heater will not give the desired output.
The WWH is not provided with a standard venting. There is the possibility to place one when it is
desired.
Prevent mechanical tension on the connections, this will cause leakage.
Warning: Prevent damage to the heater, hold the
connections with pliers to avoid twisting of welded parts
of the connections. Do not put excessive force! Internal
welds may break and cause leakage.
