DANGER
Do Not Use Equipment for Purposes Other Than Those Specified
• The NH-2001-DV/ NH-1501-DV is a boiler to be used for space heating or indirect water
heating only. Do not use the hot water supplied by the boiler for drinking purposes.
• This boiler has a pressure rating of up to 150 psi, but it is designed to be used in a low pressure (15 psi) closed loop heating system. Use a 30 psi relief valve.
Checkup
• Once a year, check the fixing brackets, the air supply and exhaust pipes and the flue terminals
to see if they need to be replaced.
WARNING
Precautions on Vent Pipe Replacement
• The vent system will almost certainly need to be replaced when this appliance is being installed.
Use vent pipe that is listed to UL 1738 for Category III appliances for the exhaust venting. Category
III listed vent pipe is suggested for the air supply pipe also, but other materials may be acceptable.
Consult local codes.
* If Category III listed vent pipe is already installed, check for punctures, cracks or blockages and
consult with the vent pipe manufacturer before reusing.
Use Approved Vent Materials
• Use only vent materials that are listed to UL 1738 for Category III appliances for the exhaust venting
of this appliance.
Improper venting may result in fires, property damage or exposure to Carbon Monoxide.
Snow Precaution
• If this product will be installed in an area where snow is known to accumulate, protect the vent
termination from blockage by snow drifts or damage from snow falling off of roofs.
Check the Gas
• Check that the rating plate indicates the correct type of gas.
• Check that the gas supply line is sized for 199,900 Btuh for
the NH-2001-DV, or 150,000 Btuh for the NH-1501-DV.
Check the Power
• The power supply required is 120VAC, at 60Hz.
Using the incorrect voltage may result in fire or electric shock.
CAUTION
Check Water Supply Quality
• If the water supply is hard, acidic or otherwise impure, treat the water with approved methods in
order to ensure full warranty coverage.
Use the Specified Anti-Freeze
• When using anti-freeze, use Noritz approved anti-freeze only.
Using an anti-freeze other than one specified by Noritz could lead to leakage of fluid (water) or
clogging of pipes.

Choosing Installation Site
4.
* Locate the appliance in an area where leakage from the boiler or connections will not result in dam-
age to the area adjacent to the appliance or to the lower floors of the structure. When such locations
cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed
under the appliance. The pan must not restrict combustion air flow.
* Install this boiler in a way that the constituent parts of the gas ignition system are protected from water
(water drops, spray, rain, etc.) during device operation and repair (circulator replacement, drain trap
or control device replacement, etc.).
DANGER
• Locate the vent terminal so that there are no obstacles around the termination and so that exhaust can't accumulate. Do not enclose the termination with corrugated metal or other materials.
WARNING
• The boiler is designed for indoor installation only. Never install it
outdoors or in a bathroom, it may be damaged or a fire may be
caused.
• Avoid places where fires are common, such as those where
gasoline, benzene and adhesives are handled, or places in which
corrosive gases (ammonia, chlorine, sulfur, ethylene compounds,
acids) are present.
Using the incorrect voltage may result in fire or cracking.
Prohibited
• Avoid installation in places where special chemical agents
(e.g., hair spray or spray detergent) are used.
Ignition failures and malfunction may occur as a result.
• Carbon Monoxide Poisoning Hazard. Do not install this boiler in a
mobile home, recreation vehicle or on a boat.
Prohibited
CAUTION
• Consult with the customer concerning the location of installation.
• Install the boiler in an area that allows for the proper clearances to combustible and noncombustible construction. Consult the rating plate on the appliance for proper clearances.
• Avoid installation in places where dust or debris will accumulate.
Dust may block the air-supply opening, causing the performance of the device fan to drop and
incomplete combustion to occur as a result.
• Do not install the boiler in a place where it may be threatened by falling objects, such as under
shelves.
• The boiler must be installed in a place where supply and exhaust pipes can be installed as
directed.
• Do not install the boiler where the exhaust will blow on outer walls or material not resistant to
heat. Also consider the surrounding trees and animals.
The heat and moisture from the boiler may cause discoloration of walls and resinous materials,
or corrosion of aluminum materials.
4
CAUTION
• Avoid installation above gas ranges or stoves.
• Avoid installation between the kitchen fan and stove. If oily
fumes or a large amount of steam are present in the installation location, take measures to prevent the fumes and steam
from entering in the equipment.
• Install in a location where the exhaust gas flow will not be
affected by fans or range hoods.
• Take care that noise and exhaust gas will not affect neighbors.
• Before installing, make sure that the exhaust flue termination
will have the proper clearances according to the National Fuel
Gas Code (ANSI Z223.1).
• Installation must conform with local codes, or in the absence
of local codes, the National Fuel Gas Code, ANSI Z223.1/
NFPA 54- latest edition and/or CSA B149.1, Natural Gas and
Propane Installation Code (NSCNGPIC).
