Noritz tankless water heater model review
Based on the venting options there are three wall hanging
models
from NR111 line you can choose from. The Noritz tankless water heater
from this group is designed as power or direct vent and is
used
installed indoor only while the outdoor model must be installed on the
outside wall or inside the recess box.
Note: Proper venting is required to protect the heater from
corrosion
and gas leak in the exhaust vent. Therefore stainless steel pipe is
required for venting gases out (Category III).

NR111-SV
Noritz NR111-SV
Noritz tankless water heater NR111-SV is a
standard model that comes with the power venting, and can
be installed indoor and
outdoor,
and vented horizontally through the outside wall or vertically through
the roof. When installing inside,
sufficient air supply should be
provided as the heater uses the inside air for combustion and
one flue pipe for venting gases out.
NR111-SV models are used in residential applications only, not
in RV, boat or mobile and manufactured home applications.

NR111-OD
Noritz NR111-OD
Noritz NR111-OD tankless water heater can only be installed
outdoor and it doesn't require venting pipes.
Recommendation is to install it in the recess box, which is an
accessory, for protection against different weather
conditions.
NR111-OD
models can be used for residential, commercial or in manufactured home
application, but not in RVs or on a boat.
Model
NR111-DV
Noritz NR111-DV
Direct vent model is for installation indoor
only. Thanks to the sealed combustion chamber the unit uses the outside
air only while the inside air is untouched. This is what makes the
NR111-DV
tankless water heater perfect for installation in
smaller rooms, and where the installation of non-combustion sealed
models is
not a viable option.
Noritz direct vent model uses either one concentric vent pipe
or two
separate pipes, but it all depends on installation preference and
viability.
These models are
suitable for use in residential, commercial and
manufactured home applications, but not in RVs or on a boat.
Every Noritz tankless water heater comes with the warranty of
12 years on heat exchanger and 5 on other parts.
