IMPORTANT SAFETY INFORMATION
READ ALL INSTRUCTIONS BEFORE USING
DANGER!
WATER TEMPERATURE SETTING
Safety and energy conservation are factors to be considered when selecting the water temperature
setting. Water temperatures above 125°F can cause severe burns or death from scalding. The thermostat
is adjusted to its lowest temperature position when shipped from the factory. Be sure to read and follow
the warnings outlined on the label pictured below.
The chart shown above may be used as a guide in
determining the proper water temperature for your
home.
DANGER: Households with small children, disabled,
or elderly persons may require a 120°F or lower
temperature setting to prevent contact with”HOT” water.
Maximum water temperature occurs while burner is on.
To nd water temperature being delivered, turn on a
hot water faucet and place a thermometer in the water
stream and read the thermometer.
The temperature of the water at the outlet of the water
heater can be regulated by setting the temperature on
the Eccotemp Smart App (pg. 41-42) or by using the
included remote (pg. 40). The default temperature was
set at 110°F before it was shipped from the factory.
NOTICE: When this water heater is supplying
general purpose hot water requirements for use
by individuals, a thermostatically controlled mixing
valve for reducing point of use water temperature
is recommended to reduce the risk of scald injury.
Contact a licensed plumber or the local plumbing
authority for further information.
NOTICE: The factory recommended operating
temperatures are between 90°F and 140°F.
Water temperature over 125°F can cause severe burns
instantly or death from scalds. Children, disabled and elderly
are at highest risk of being scalded. See instruction manual
before setting temperature at water heater. Feel water
before bathing or showering. Temperature limiting valves are
available, see manual.

DANGER!
NATURAL GAS AND LIQUEFIED PETROLEUM MODELS
Both LPG and natural gas have an odorant added to aid in detecting a gas leak.
Some people may not physically be able to smell or recognize this odorant. If you
are unsure or unfamiliar with the smell of LPG or natural gas, ask the gas supplier.
Other conditions, such as “odorant fade”, which causes the odorant to diminish in
intensity, can also hide or camouage a gas leak. Always check with commercial
leak detector or soapy water.
• Gas detectors are recommended in LPG and natural gas applications and
their installation should be in accordance with the detector manufacturer’s
recommendations and/or local laws, rules, regulations or customs.
• Water heaters utilizing LPG are dierent from natural gas models. A natural
gas water heater will not function safely on LPG and vice versa.
• No attempt should ever be made to convert the water heater from natural gas
to LPG. To avoid possible equipment damage, personal injury or re, do not
connect the water heater to a fuel type not in accordance with the unit data
plate; propane for propane units and natural gas for natural gas units. These
units are not certied for any other fuel type.
• LPG water heaters should not be installed below grade (for example, in a
basement) if such installation is prohibited by federal, state and/or local laws,
rules, regulations or customs.
• Propane or LPG must be used with great caution. It is heavier than air and
will collect rst in lower areas making it hard to detect at nose level.
• Before attempting to light the water heater, make sure to look and smell for
gas leaks. Use a soapy solution to check all gas ttings and connections.
Bubbling at a connection indicates a leak that must be corrected. When smelling
to detect a gas leak, be sure to sni near the oor also.
• It is recommended that more than one method, such as soapy solution, gas
detectors, etc., be used to detect leaks in gas applications.
NOTICE: If a gas leak is present or suspected:
• DO NOT attempt to nd the cause yourself.
• DO NOT try to light any appliances.
• DO NOT touch any electrical switch.
• DO NOT use any phone in your building.
• Leave the house immediately and make sure your family and pets leave
also.
• Leave the doors open for ventilation and contact the gas supplier, a
qualied service agency or the re department.
• Stay away from the house (or building) until the service call has been
made, the leak is corrected and a qualied agency has determined the
area to be safe.

supplier or local plumbing inspector on how to control this situation.
Install a shuto valve near the inlet of the water heater for service and
draining purposes.
Before connecting the water supply pipe to the water heater, open
the shuto valve and clean out sand, debris, air, caulking material,
etc. inside the pipe. Connect to the water inlet, then check water ow.
Close the shuto valve and clean the water lter.
Be sure to connect the water inlet and the hot water outlet as shown
on the water heater. If reversed, the water heater will not function.
Installation of unions or exible copper connections are
recommended on the HOT and COLD water lines, so that the water
heater may disconnect easily for servicing if necessary.
Install a check valve between the water heater and the water shuto
valve. (See illustration to the top left).
In regards to the HOT WATER OUTLET:
Connections between the water heater and point(s) of use should be
as short and direct as possible.
DO NOT use lead or non-approved plastic pipe.
NOTICE: The ow rate of hot water may vary when more than
two faucets (appliances, xtures, etc.) are being used simultaneously.
NOTICE: The pipes MUST be completely drainable. If the hot water faucets are located at a point
higher than the water heater, place a drain valve at the lowest point (see illustration to the bottom left).
Gas Supply
WARNING: Do not attempt to convert this water heater for use with a dierent type of
gas other than the type shown on the rating plate. Such conversion could result in hazardous
operating conditions. Please have a professional connect the gas pipe.
A manual gas appliance shuto
valve must be installed at the gas
connection of the water heater at the time
of installation (see diagram to the left).
The branch gas supply line to the water
heater should be clean black steel pipe or
other approved gas piping material.
A ground joint union or ANSI design
certied semi-rigid or exible gas
appliance connector should be
installed in the gas line close to the
water heater. The National Fuel Gas
Code (NFGC) mandates a manual gas
shut o valve: See (NFGC) for complete
instructions.
If exible connectors are used, the
maximum length shall not exceed 36”. The
minimum BTU requirement for ex and/or
gas lines is 1” of black steel, ex rated at
199K BTU.
If lever type gas shut os are used, they
shall be T-Handle type.
Compound used on the threaded
joints of the gas piping must be of
the type resistant to the action of LPG
gas. Use compound sparingly on male
threads only.

• No valve of any type should be installed between the
relief valve and the water heater.
• Discharge from the relief valve should be piped to a
suitable drain to eliminate potential water damage.
Piping used should be of a type approved for the
distribution of hot water.
• Hot and cold water lines should be insulated up to the
water heater.
• The discharge line must be NO SMALLER than the outlet
of the valve and must pitch downward to allow complete
drainage (by gravity) of the relief valve and discharge line.
• The end of the discharge line should not be threaded or
concealed and should be protected from freezing. No
valve of any type, restriction or reducer coupling should
be installed in discharge line.
NOTICE: Local codes govern the installation of relief valves. If local codes require that a
temperature and pressure relief valve should be installed the manufacturer recommends a type 40XL
Watts T&P relief valve or an equivalent model be used.
NOTICE: Manual operation of relief valves should be performed at least once a year. Turn o the
electrical power and gas shut o valve. Lift and release lever on the relief valve and check the manual
operation of the relief valve. You should take precaution to avoid contact with the hot water coming
out of the relief valve and to prevent water damage.
NOTICE: If the relief valve on the system discharges periodically, this may be due to thermal
expansion in a closed water supply system. Contact the water supplier or local plumbing inspector on
how to correct this situation. Do not plug the relief valve.
A new pressure relief valve, complying with the Standard for relief Valves and Automatic Gas shut o
Devices for Hot Water Supply Systems, ANSI Z21.22, must be installed at the hot water outlet connection of
the water heater at the time of installation. Local codes shall govern the installation of relief valves.

WARNING : Moisture in the ue
gas will condense as it leaves the vent
terminal. In cold weather this condensate
can freeze on the exterior wall, under
the eaves and on surrounding objects.
Some discoloration to the exterior of
the building is to be expected. However,
improper location or installation can
result in severe damage to the structure
or exterior nish of the building. Code
requirements are subject to change and
may vary by location.
Leak Testing
WARNING: Never use an open ame to test for gas leaks, as property damage, personal
injury, or death could result.
The water heater and its gas connections must be leak tested at normal operating pressures before
it is placed in operation.
• Turn on the gas shut o valve(s) to the water heater.
• Use a commercial leak detector or soapy water solution to test for leaks at all connections and ttings.
Bubbles indicate a gas leak that must be corrected.
The factory connections should also be leak tested after the water heater is placed in operation.
High Altitude
Ratings of gas water heaters are based on sea level operation and need not be changed for installations at
elevations up to 2,000 feet. Unit not recommended for elevations in excess of 2,000 feet.
Installing the Water Heater
Flue Terminal Location
The location of the vent terminal depends on the following minimum clearances and considerations
(see illustration):
• Twelve (12) inches above grade level and above normal snow levels.
• Four (4) feet below, or four (4) feet horizontally from any door,
window, sot, under eave vent or gravity air inlet to the building
or other appliances, or from gas or electric meters. Do not locate
vent above walkways, doors, windows, air inlets, gas or electric
meters or other equipment.
• Ten (10) feet from any forced air inlet to the building. Any fresh or
make-up air inlet such as for a dryer or furnace area is considered
to be a forced air inlet.
• Eighteen (18) inches from an inside corner formed by two exterior walls.
•DO NOT install vent terminal under any patio/deck or too close
to shrubbery, as ue gases or condensate vapor may become a
nuisance or hazard and may cause property damage. Condensate
vapor could cause damage and be detrimental to the operation of
regulators, relief valves, or other equipment.
• To help prevent moisture from freezing on walls and under eaves,
do not locate vent terminal on the side of a building with
prevailing winter winds. The water heater must be located as
close as possible to a chimney or gas vent.
• Caulk all cracks, seams and joints within six (6) feet of vent terminal.
• All painted surfaces should be primed to lessen the chance of
physical damage. Painted surfaces will require maintenance.
• Use of cellular core PVC (ASTM F891), cellular core CPVC, or
Radel (polyphenylsulfone) in non-metallic venting systems is
prohibited. Covering non-metallic vent pipe and ttings with

• To supply hot water to upper oors,
additional water pressure (0.44 psi/ft)
must be ensured.The measurement should
be calculated by the distance between the
water inlet of the water heater (ground
level) to the hot water faucet (upper oor level).
• Well water systems should be set at a
range of 50-60 psi.
• When the water is supplied from a water
supply tank, the height of the tank and the
diameter of the pipes and their relation to
water pressure, should be taken into
consideration. Gravity water pressure is
not recommended.
NOTICE: If the water ow resistance of a
shower head is too high, the burner in the water
heater will fail to ignite. Keep the shower head
clean from debris that could cause additional
pressure drop.
NOTICE: If using mixing valves on the outlet,
choose one which prevents cold water pressure
from overcoming hot water line pressure.
IMPORTANT: Do not apply heat to the HOT or
COLD water connections. Any heat applied to the
water supply ttings will permanently damage the
internal components of the water heater.
Water Supply Connections
Plumbing should be carried out by a qualied
plumber in accordance with local codes.
Use approved plumbing materials and tools only.
To conserve energy and to prevent freezing, insulate
both cold and hot water supply lines. DO NOT cover
the drain valves.
To ensure proper operation of the water heater,
the following water pressure guidelines should be
followed:
• Operation of the water heater requires the
minimum water pressure of 14 psi and a
minimum water ow rate of 0.75 gpm.
• Additional water pressure is required for
long pipe runs and outlet tting(s) water
pressure drops.
• To maintain proper performance, ensure
sucient water supply pressure. The
Required Water Pressure = Min. Operating
Water Pressure (14 psi) + Pipe Pressure
Loss + Faucet and Shower Pressure Loss +
Safety Margin (more than 5 psi).
Mounting the SH22 Water Heater
Make sure the location of the water heater allows for easy access
and operation. The water heater should be located in an area where leakage of
the tank or connections will not result in damage to the area adjacent to the water
heater or to lower oors 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 ow.
In case of dry wall or concrete wall use dry wall anchors or lag bolts.
The water heater requires 120VAC/ 60Hz. Have a receptacle with ground terminal

Indoor Location
• Installation distances may vary by local code. It is the installer’s responsibility to verify
installation requirements.
• Make sure before installation that the gas type you will use is the same type on the data
plate.
• The water heater unit should be installed by professionals. Improper installation may
cause failure or dangerous conditions such as gas leaking or explosion.
• Water heater cannot be installed in an UN-VENTED bathroom, bedroom, basement, living
room, closet, outdoor, stairway or an exit area. If installed in an exit area, it must be at
least 16.5 ft. or more away from the exit.
• Vent pipe should extend from the wall at least 2”. The terminal must be at least 1.64 ft.
away from obstruction and must be well vented.
• Vent pipe should slope 3° downward, to avoid condensing water and protect from rain
entering.
• Vent pipe should avoid direct, strong wind because the downdraft will cause malfunction.
• The water heater should be installed far from any blockage, and with plenty of enough
space for installation and maintenance. Adequate clearances for servicing must be
provided.
• The water heater should not be installed in the same room with a gas stove .
• When determining the oor clearance, a clearance of 12 inches must be maintained
between the vent pipe and combustible material. A side wall clearance of 10 inches and a
top clearance of 16 inches must be maintained.
• The vent pipe can be up to 32 ft. in length with one elbow.
• The vent pipe should be installed with a ame retardant wall thimble. Owner must refer to
vent manufacturer’s instructions and specications. Z-Flex information can be found at
www.novaex.com, please refer to page 31 for additional links. Installation guidelines for
venting provided by NovaFlex, who is solely responsible for venting installation accuracy.
• The power socket connecting the water heater should be grounded properly with a GFCI
circuit protector.
• The water heater should not be located in an area where leakage of the heat exchanger
or connections will result in damage to the area adjacent to it or to lower oors of the
structure.When such areas cannot be avoided it is recommended that a suitable catch
pan, adequately drained, must be installed under the water heater. The pan must not
restrict combustion airow.
• The water heater should be installed as close as practical to the vent termination to
minimize vent length and the number of elbows required for venting.
• A gas red water heater or any other appliance should not be installed in a space where
liquids which give o ammable vapors are to be used or stored. Such liquids include
gasoline, LPG (butane or propane), paint or adhesives and their thinners, solvents or
removers.
• The water heater should be installed far from heat sources, ammable and dangerous
materials. Because of natural air movement in a room or other enclosed space, ammable
vapors can be carried some distance from where their liquids are being used or stored. The
open ame of the water heater’s main burner can ignite these vapors causing an explosion
or re which may result in severe burns, death or property damage.
