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 control panel. The control panel was set at 110°F before it
was shipped from the factory.
The illustration to the bottom left illustrates the control
panel and how to adjust the water temperature.
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 setting allows operating temperatures
between 90°F and 140°F.
NOTICE: This is a manual water heater. This means that
the temperature must be set and regulated from the front
control panel on the water heater and NOT at your sink or shower. Adjusting the water temperature from the sink will lower the pressure activation point and turn the water heater o. DO NOT adjust water temperature via your sink or shower. You MUST adjust the temperature at the face of the water heater using the control panel. The FVI12 is
a pressure activated manually operated tankless water
heater.

DANGER!
NATURAL GAS AND LIQUEFIED PETROLEUM MODELS
Both LP 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 LP 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 camouage a gas leak. Always check with commercial
leak detector or soapy water.
• Gas detectors are recommended in LP 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 LP gas are dierent from natural gas models. A natural
gas water heater will not function safely on LP gas and vice versa.
• No attempt should ever be made to convert the water heater from natural gas to LP gas. To avoid possible equipment damage, personal injury or re, do not
connect the water heater to a fuel type not in accordance with the water heater data plate; propane for propane water heaters and natural gas for natural gas
water heaters. These water heaters are not certied for any other fuel type.
• LP 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 LP gas 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 operate 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 qualied 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 qualied agency has determined the area to be safe.

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 should be installed by professionals. Improper installation may cause failure or dangerous conditions such as gas leaking or explosion.
Failure to have the water heater installed by a professional will void your warranty.
The water heater cannot be installed in an un-vented bathroom, bedroom, basement, living room,
closet, outdoors, laundry room, 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 6 inches must be maintained between the
vent pipe and combustible material. A side wall clearance of 6 inches and a top clearance of 12 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 specications. Z-Flex information can be found at www.novaex. com, please refer to page 19 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 airow.
This water heater CANNOT be installed in a laundry room or in the same room as the washer/dryer. Installation of the water heater in a laundry room or in the vicinity of a washer/dryer will void the
warranty.
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, LP gas (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.

The air must be supplied through two permanent openings of equal area. One is to be located within 12” above the oor and the other is to be located within 12” below the ceiling.
The minimum net free area of each opening must not be less than one square inch per 1,000 BTUH of the total input rating of all the appliances in the enclosure (but not less than 100 square inches), if each opening communicates with other unconned areas inside the building.
Buildings of unusually tight construction shall have the combustion and
ventilation air supplied from outdoors, or a freely ventilated attic or crawl space. If air is supplied from outdoors, directly or through vertical ducts,
there must be two openings located as specied above and each must have a minimum net free area of not less than one square inch per 4,000
BTUH of the total input rating of all the appliances in the enclosure.
If horizontal ducts are used to communicate with the outdoors, each opening must have a minimum net
free area of not less than one square inch per 2,000 BTUH of the total input rating of all the appliances in the enclosure. If ducts are used, the minimum dimensions of rectangular air ducts shall not be less than 4”.
Inspect Shipment
Inspect the water heater for possible damage. Check the markings on the rating plate of the water heater to be certain
the type of gas supplied corresponds to the water heater
requirements. Verify all included parts are present (see below).
NOTICE: If the water heater is installed in an unconned space within a building of conventional frame, masonry or metal construction, inltration air is normally adequate for proper combustion and ventilation air must be made.
NOTICE: If the duct openings which supply combustion and ventilation air are to be covered with a protective screen or grill, the net free area (openings in the material) of the covering material must be used in determining the size of openings. Protective screening for the openings MUST NOT be smaller than ¼” to prevent clogging by lint or other debris.
Corrosive Atmospheres
The air in beauty shops, dry cleaning establishments, photo processing labs, and storage areas for liquid and powdered bleaches
or swimming pool chemicals often contain such
halogenated hydrocarbons.
An air supply containing halogenated
hydrocarbons may be safe to breathe, but when it passes through a gas ame corrosive elements
are released that will shorten the life of any gas
burning appliance.
Propellants from common spray cans or gas
leaks from A/ C and refrigeration equipment are highly corrosive after passing through a ame.
The water heater warranty is voided when failure of the heater is due to operation in a corrosive atmosphere.
NOTICE: The water heater should not be
installed near any air supply containing
halogenated hydrocarbons.

To conserve energy and to prevent freezing, insulate both cold
and hot water supply lines. DO NOT cover the drain valves.
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 pressure. Close the shuto valve and clean the water lter.
If a water heater is installed in a closed water supply system, such as
one having a backow preventer in the cold-water supply line, means shall be provided to control thermal expansion. Contact the water supplier or local plumbing inspector on how to control this situation.
CAUTION: This water heater must only be used with the following water supply system conditions:
• With clean, potable water free of corrosive chemicals, sand, dirt, or other contaminates.
• With inlet water temperatures above 32°F, but not to exceed 120°F.
• Free of lime and scale deposits.
DO NOT reverse the hot and cold water connections. The water heater will not operate.
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 20 psi to activate and a minimum of 22 psi or greater to maintain activation.
Additional water pressure is required for long pipe runs and outlet tting(s) water pressure drops.
To maintain proper performance, ensure sucient water supply pressure. The Required Water
Pressure = Min. Operating Water Pressure (22 psi) + Pipe Pressure Loss + Faucet and Shower Pressure Loss + Safety Margin (more than 5 psi).
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.
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.
NOTICE: If the water pressure 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.
DO NOT use pipes with smaller diameters than the water supply connection of the water heater.
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.
Plumbing should be carried out by a qualied plumber in accordance with local codes. Use approved plumbing materials and tools only. Install a Check Valve between the water heater and the water shuto valve (See illustration below).

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.
• To conserve energy and minimize heat loss, insulation of hot water piping is recommended.
NOTICE: The pressure 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 diagram to the left).
The 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 certied 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.
A sediment trap should be installed at the bottom of the gas line.
The inlet gas pressure to the water
heater must not exceed 10.5“ w.c. for natural or 14” w.c. for LP gas. For
purposes of input adjustment, the minimum inlet gas pressure (with main
burner on) is shown
on the water heater rating plate. If high or low gas pressures are present, contact your gas supplier for correction
The water heater and its indivdual
shuto valve must be disconnected
from the gas supply piping system during any pressure testing of that system at test pressures
in excess of ½ psi (3.5 kPa). The water heater must be isolated from the gas
supply
piping system by closing its individual manual shuto valve during any
pressure testing of the gas supply
piping system at test pressures equal to or less than ½ psi (3.5 kPa).
WARNING: Do not attempt to convert this water heater for use with a dierent 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.
DO NOT use excessive force (over 31.5 ft lbs.) in tightening the pipe, particularly if pipe compound is used, as the water heater may be damaged.
Compound used on the threaded joints of the gas piping must be of the type resistant to the action of LP
gas. Use compound sparingly and use on male threads only.

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. All connections should also be leak tested after the water heater is placed in operation.
Pressure Testing the Gas Supply System
WARNING: Install a gas pressure regulator, in the gas supply line, which does not exceed the maximum supply pressure. DO NOT use an industrial type gas regulator.
The water heater must be isolated from the gas piping system by closing the manual gas shut-o valve during any pressure testing of the gas supply piping at pressures equal to or less than 1/2 psi (14’w.c.) .
Ratings of gas appliances are based on sea level operation and need not be changed for installations at elevations up to 2,000 ft. This water heater is not recommended for elevations in excess of 2,000 ft.
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. Pressure relief valves are not included with your water heater but are available for purchase at www.eccotemp.com
For safe operation of the water heater, be sure that:
• The pressure rating of the relief valve must not exceed 150 psi, the maximum working pressure of
the water heater as marked on the rating plate.
• The BTUH rating of the relief valve must equal or exceed the BTUH input of the water heater as
marked on its rating plate.
• 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: The diagram below illustrates a pressure only relief valve. If local codes require a combination temperature and pressure relief valve be installed, an extension piece may be needed.
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 shuto 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.

The installation of venting must comply with national codes, local codes, and the vent manufacturer’s instructions. Owner must refer to vent manufacturer’s instructions and
specications. Z-Flex information can be found at www.novaex.com,
please refer to page 18 for additional links.
The water heater must be vented to the outdoors as described in these
instructions. DO NOT connect this
water heater to an existing Vent or Chimney: it must be vented separately
from all other appliances.
All vent components (adapters, pipe,
elbows, terminals, etc.) should be UL 1738 Certied Stainless Steel Venting Material (e.g. AL29-4C).
The specied vent termination must be used. The termination must be used. The termination should be a 90° elbow type with screen. (Refer to page 18).
Use a vent pipe with an antidisconnection structure. The use of a High Temperature
Silicone (500° F) may be required to
seal vent connections. To prevent
accidental gas exhaust leakage, apply a ¼” wide bead approximately ¼” from the end and another bead
against the joint side of the stop
bead.
Follow vent manufacturer’s installation instructions.
The water heater can be vented either
horizontally or vertically.
Vent pipe runs must be adequately supported along both horizontal and
vertical runs.
The maximum recommended unsupported span should be no more than ve (5) feet. Support isolation hanging bands should be used. DO
NOT use wire. (See diagram below).
DANGER: Failure
to install the vent
adapter and properly
vent the water heater
to the outdoors as outlined in the Venting section of this manual will result in unsafe operation of the water heater causing death, serious injury, explosion, or
re. To avoid the risk of re, explosion,or
asphyxiation from
carbon monoxide,
NEVER operate the water heater unless it
is properly vented and has adequate
air supply for proper operation as outlined in the Venting section of this manual.
WARNING: Use
UL approved Category III Stainless Steel vent
material only. No
other vent material
is permitted. Owner
must refer to vent manufacturer’s
instructions and
specications. Z-Flex
information can
be found at www. novaex.com, see
page 18 for additional links.
WARNING: Refer to pages 16-17 for clearances to
combustible material.
If the vent piping passes through a closed space, wrap the vent pipe with inammable insulation material that is at least 3/4” thick. DO NOT let the insulation material make contact with ammable materials. A minimum clearance of 6” between the vent pipe and ceiling should be maintained. Follow local codes.
For maintenance and inspection purposes, the following holes are
required to be made:
• Two (2) inspection openings that allow access to venting. One ( 1) of these openings should be close to where the vent pipe enters the ceiling. The other opening should be near the vent
termination.
• A ventilation hole with a 16 sq. in. opening should be made at
least every 10 feet.
NOTICE : Vent pipes must be completely insulated with
inammable material when installed in alcoves, closets, and garages and must not touch any ammable

MAXIMUM VENT LENGTH
Owner must refer to vent manufacturer’s instructions and specications. Z-Flex information can be found at www.novaex.com, please refer to page 19 for additional links.
The system will not operate if there is excessive restriction (pressure drop) in the venting system. A maximum of 32 feet of vent pipe may be used provided there is only one 90° elbow in the system. If additional elbows are required: two elbows can be used with 27 feet, and three elbows can be used with 22 feet of vent pipe.
A 90° elbow is equivalent to 5 feet of straight pipe. A 45° elbow is equivalent to 2 feet 6 inches of straight pipe.
The termination elbow does not count as an elbow when
determining total vent lengths.
The vent must be installed with a slight downward slope of ¼” per foot of horizontal run toward the vent terminal (see diagram below).
This ensures that any condensate formed during operation of the water heater evacuated from the water heater.
A ¼” per foot upward slope is acceptable when it is not possible to
vent with a downward slope, however, a UL approved Category III
Stainless Steel condensate trap MUST be installed at the beginning
of the horizontal run (See page 20 “Typical Horizontal Termination
w ¼” per foot UPWARD Slope” or page 14, “Standard Vertical Vent Termination” for examples).

The venting may be as short as 12”,
provided one vent termination is installed to the outdoors through a
sidewall, one 90° elbow is included in the installation, and the wall thimble is
installed.
NOTICE: Make sure that the seam of the vent pipe in horizontal runs is toward the top of the installation
(see illustration to the left)
Draining the Condensate
In certain conditions, installations in unconditioned space or having long horizontal or vertical runs may accumulate condensate.
Condensate is known to be acidic; refer to local, state (provincial) or federal codes for proper
handling methods.
In order to prevent condensate from draining back into the water heater, we recommend a condensate trap and drain to be installed in a horizontal vent section as close as practical to
the water heater vent connection.
Not following proper condensate procedures will void warranty.

WARNING: Use UL approved Category III vent material only. No other vent material is
permitted. Owner must refer to
vent manufacturer’s instructions and specications. Z-Flex information can be found at www.novaex.com, refer to page
18 for additional links.
CAUTION: Follow the vent
manufacturers installation
instructions as design might vary
om manufacturer to manufacturer.
Only the 2” vent kit provided with the FVI12 or approved Z-Flex Stainless Steel venting should be used for installation.
The wall thimble requires mechanical support from the wall suf­fucuent to support any incidental loads on the system. If the wall is not sucient enough to support the wall thimble, then appropri­ate additional framing and/or blocking is required.
INSTALLATION PROCEDURE:
Prepare an opening for the wall thimble in the wall. The opening must be 6-1/2 inches in diameter for a 3” vent system. The opening should be round.
The opening must be able to accommodate the 2” vent system and wall thimble provided. Consult manual or building codes for distance from amable materials.
The wall thimble is designed to adapt to any wall thickness from 3-1/2” to 6” thick. If the wall is thicker than 6” the wall thimble may be extended using a piece of 6” diameter snaplock or welded seam galvanized pipe up to 6” long.
Select the larger diameter half of the wall thimble for the outside of
the wall.
Apply a continuous bead of high quality silicone or silicone/la-
tex caulk on the inside of the outer ange. This will be the only weather seal to keep moisture outside the building. Ensure a sucient seal is made.
Position this portion of the wall thimble into the prepared hole from the outside. Secure the assembly into the prepared open­ing using fasteners as indicated by sheathing or structural mem­bers, sealing the screw heads with more caulking.
Use 4 hollow wall anchors, at least 1/8” in diameter and of appropri-
ate length for the thickness of the sheathing, if sheathing is particle
board or other composite material. Use 4 #10x1-1/4” wood screws for plywood, solid wood sheathing or members. Use suitable mason-
ry anchors when passing through solid masonry walls. Reinstall the
decorative sheathing around the wall thimble. This assembly may be painted to match the exterior decor.
Slide the interior portion of the thimble into the inside hole. Be certain the interior and exterior thimble halves overlap at least 1”. If insucient overlap exists, extend the interior portion with
single wall galvanized pipe.
Secure the vent section that protrudes through the wall thimble
to the 90 degree elvbow attached to the water heater.
The exhaust pipe should be sloped downward at an approximate 3 degree grade in order to avoid rain (or condensation entering
the heater) through the exhaust pipe.

Setting the Temperature:
The Eccotemp FVI12-LP/NG models are MANUAL TEMPERATURE CONTROLLED water heaters.
This means that the temperature must be adjusted on the face plate of the water heater and not at the output source (sink or shower).
When you try to mix hot water with cold at the output source, the heater will shut down because as you mix in the cold water, you are decreasing the amount of required water pressure to keep
the water heater activated. The FVi12 is a pressure activated water heater and should maintain
at least 40-60 PSI of water pressure. When cold water is added, the pressure drops below the
activation point.
Manual Temperature Control: You must adjust both
the gas knob and water knob in order to set the desired
output temperature of this water heater. As incoming
ground water temperatures changes, adjustments to both the gas and water knob may be necessary to achieve
desired output temperature. Since this water heater is
pressure activated, adjustments may need to be made manually to both water and gas knobs based on incoming
water pressure or incoming water pressure.
NOTICE: If inlet water temperature is high, and set
temperature is low, the actual temperature might be higher than the set temperature, and viceversa..
DANGER: There is a hot water scald potential if the temperature is set too high. Households with
small children, disabled, or elderly persons may require a 120°F or
lower temperature setting to
prevent contact with HOT water.
Output temperature of water is regulated by
setting the temperature on the front of the water
heater. Safety factors should be considered when
selecting the water temperature.
Water temperature above 120°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 in this manual and on the label located on the water heater. Mixing valves are available for reducing point of use water temperature by mixing hot and cold water in branch water lines.
Procedures for adjusting the thermostat for
energy ecient operation at the minimum
water temperature setting consistent with the
consumer’s needs.
Contact a licensed plumber or the local plumbing
authority for further information. See page 4 for details.

Properly maintained, your water heater
will provide years of dependable trouble-free service. It is recommended that a periodic inspection of the burner, relief valve, water lter and venting system should be made by service personnel qualied in gas appliance
repair.
It is suggested that a routine preventive
maintenance program be established and followed by the user.
At least once a year, lift and release the lever handle on the pressure relief valve, located in the hot outlet piping of the water heater, to make certain the valve operates freely. Allow several gallons to
ush through the discharge line to an
open drain.
Rapid closing of faucets or solenoid valves in automatic water using
appliances can cause a banging noise
heard in a water pipe. Strategically located risers in the water pipe system or water hammer arresting devices can
be used to minimize the problem.
Inspect the area around the water heater to ensure a safe operating environment. Keep water heater
area clear and free from combustible
materials, gasoline, and other
ammable vapors and liquids. Ensure the water heater has not been
damaged. If damage or denting is present, contact a service personnel to verify proper operation.
Check for any abnormal sounds during
normal operation of the water heater.
All piping should be checked for gas
and/or water leaks. Refer to page 14 of this manual for instructions on leak testing.

DANGER: Before
manually operating
the relief valve, make
certain no one will
be exposed to the
danger of the hot
water released by the valve. The water may be hot enough to
create a scald hazard.
The water should be
released into a
suitable drain to prevent injury or
property damage.
DANGER: Hotter water increases the potential for Hot Water Scalds.
DANGER: Failure to perform the recommended
Routine Preventative
Maintenance can harm the proper operation of this water heater, which
can cause carbon
monoxide dangers,
excessive hot water
temperatures and other potentially hazardous conditions.
Housekeeping
