• Temperature and Pressure Relief Valve (Ships Installed)

• High Output Cold Water Dip Tube

• Installation Manual and Warranty

• User’s Information Manual

B. How the Heater Operates

Modulating Condensing Technology is an intelligent system

that delivers highly ecient water heating, maximizing eciency by measuring the data parameters of your water heating system. Some of its features are:

Stainless Steel Water Storage Tank

The stainless steel water storage tank has a combustion chamber submerged into the tank water. When the water heater is red, combustion gases heat the combustion chamber walls, transferring heat directly into the surrounding water. These hot gases are blown into secondary heat exchanger coils, where more heat from these gases is transferred into the water.

Modulating Combustion System

The control monitors the water heating system and temperatures, regulating burner output during operation to match system demand. This increase in eciency allows for substantial fuel savings.

High Output Cold Water Dip Tube (Optional - Shipped with Heater)

When installed, the High Output Cold Water Dip Tube increases hot water draw and recovery time by 20% and decreases thermal eciency by a small amount.

Gas Valve

The gas valve senses suction from the blower, allowing gas to ow only if the gas valve is energized and combustion air is owing.

Tank Sensor

This sensor monitors system water temperature. The control module adjusts burner ring rate so the outlet water temperature meets the set point.

Control

The integrated control system monitors water temperature and adjusts fan speed to regulate the heater’s energy output. This allows the unit to deliver the required amount of heated energy and nothing more.

Burner

Constructed of high grade stainless steel, the burner uses premixed air and gas and provides a wide range of ring rates.

Condensate System with Built-In Neutralizing Cartridge

This is a condensing high eciency water heater with a condensate removal system. Condensate is nothing more than water vapor derived from combustion products, similar to that of an automobile when it is initially started. It is very important that the condensate line slopes away from the water heater and down to a suitable inside drain. The Built-In Neutralizing Cartridge is lled with marble chips that neutralize the condensate before it ows into a local drain. The marble chips dissolve over time. The cartridge is designed to be easily removed, relled with marble chips, and reinstalled. If the condensate outlet on the heater is lower than the drain, us a condensate removal pump (Part # 554200, available from HTP). In addition, local authorities may require an additional condensate neutralizer to neutralize the condensate. It is also very important not to expose the condensate line to freezing temperatures or any type of blockage. Plastic tubing must be the only material used for the condensate line. Steel, brass, copper, or other materials will be subject to corrosion or deterioration. A second vent may be necessary to prevent condensate line vacuum lock on a long horizontal run. Also, an increase in pipe size may be necessary to allow condensate to drain properly. Support of the condensate line may be necessary to avoid blockage of the condensate ow.

Spark Ignition

The burner ame is ignited by applying high voltage to the system spark electrode. This causes a spark from electrode to ground.

C. Optional Equipment

Optional equipment available from HTP (and Part #):

• 3” Stainless Steel Outside Vent Termination Kit (V1000)

• 2” PVC Concentric Vent Kit (KGAVT0501CVT)

• 3” PVC Concentric Vent Kit (KGAVT0601CVT)

• 3” Polypro Vent Kit (8400P-001)

• 3” Polypro Pipe

(33’ length # 8400P-002, 49.5’ length # 8400P-003)

• Outdoor Sensor (7250P-319)

• Condensate Neutralizer Replacement (7700P-026)

Part 3 - Prepare the Water Heater

Remove all sides of the shipping crate to allow the heater to be moved into its installation location.

COLD WEATHER HANDLING - If the water heater has been stored in a very cold location (BELOW 0oF) before installation, handle with care until the components come to room temperature. Failure to do so could result in damage to the water heater.

Carefully consider installation when determining heater location. Please read the entire manual before attempting installation. Failure to properly take factors such as heater venting, piping, condensate removal, and wiring into account before installation could result in wasted time, money, and possible property damage and personal injury.

LP-441 Rev. 3.16.15

A. Locating the Water Heater

This water heater is certied for indoor use only. DO NOT INSTALL OUTDOORS. Outdoor installations ARE NOT covered by warranty. Failure to install the water heater indoors could result in property damage, severe personal injury, or death.

Incorrect ambient conditions can lead to damage to the heating system and put safe operation at risk. Ensure that the installation location adheres to the information included in this manual. Failure to do so could result in property damage, serious personal injury, or death. Failure of heater or components due to incorrect operating conditions IS NOT covered by product warranty.

1. Installation Area (Mechanical Room) Operating Conditions

• Ensure ambient temperatures are higher than 32oF / 0oC and lower than 104oF / 40oC

• Prevent the air from becoming contaminated by the products, places, and conditions listed in this manual

• Avoid continuously high levels of humidity

• Never close existing ventilation openings

• Ensure a minimum 1” clearance around hot water and exhaust vent pipes

• NOTE: To prevent condensing in the fan, it is recommended to avoid prolonged exposure to temperatures below 45oF

This water heater has a condensate disposal system that may freeze if exposed to sustained temperatures below 32oF. Precautions should be taken to protect the condensate trap and drain lines from sustained freezing conditions. Failure to take precautions could result in property damage, severe personal injury, or death.

2. Check for nearby connections to:

• System water piping

• Venting connections

• Gas supply piping

• Electrical power

• Condensate drain

3. Check area around heater. Remove any combustible materials, gasoline, and other ammable liquids.

Failure to keep the water heater area clear and free of combustible materials, liquids, and vapors can result in substantial property damage, severe personal injury, or death.

The service life of the water heater’s exposed metallic surfaces, such as the casing, as well as internal surfaces, such as the heat exchanger, are directly inuenced by proximity to damp and salty marine environments. In such areas higher concentration levels of chlorides from sea spray coupled with relative humidity can lead to degradation of water heater components. In these environments, heaters must not be installed using direct vent systems which draw outdoor air for combustion. Such heaters must be installed using room air for combustion. Indoor air will have a much lower relative humidity, and hence potential corrosion will be minimized. High heat sources (generating heat 100oF / 37oC or greater, such as boiler ue pipes, space heaters, etc.) may damage plastic components of the water heater as well as plastic vent pipe materials. Such damages ARE NOT covered by warranty. It is recommended to keep a minimum clearance of 8” from high heat sources. Observe heat source manufacturer instructions, as well as local, state, provincial, and national codes, laws, regulations, and ordinances when installing this water heater and related components near high heat sources. Locate the water heater where any leakage from the relief valve, related piping, tank, or connections will not result in damage to surrounding areas or lower oors of the building. The water heater should be located near a oor drain or installed in a drain pan. Leakage damages ARE NOT covered by warranty. Failure of the water heater or components due to incorrect operating conditions IS NOT covered by product warranty.

4. Gas control system components must be protected from dripping water during operation and service.

5. If the heater is to replace an existing heater, check for and correct any existing system problems, such as:

• System leaks

• Location that could cause the system and heater to freeze and leak

• Incorrectly sized expansion tank

6. Clean and ush system when reinstalling a heater.

NOTE: When installing in a zero clearance location, it may not be possible to read or view some product labeling. It is recommended to make note of the heater model and serial number.

B. Leveling

In order for the condensate to properly ow out of the collection system, the area where you locate the heater must be level. Location must also fully support the weight of the lled water heater.

LP-441 Rev. 3.16.15

Page 8

C. Clearances for Service Access

All water heaters eventually leak. It is recommended to install a catch pan beneath the water heater. This catch pan should be sized with a maximum depth of 2”, and a minimum diameter 2” greater than the diameter of the water heater. The catch pan should empty into an open drain line. This drain line should be 3/4” ID minimum, piped to an open drain. Failure to follow these instructions could result in property damage. Such damages ARE NOT covered by product warranty.

D. Residential Garage Installation

Precautions

If the heater is located in a residential garage, per ANSI Z223.1:

• Install the water heater burner and ignition devices a minimum of 18” above the oor of the garage. This will ensure the burner and ignition devices are well o the oor.

• When raising the water heater ensure the entire bottom and fully lled weight of the water heater are fully supported.

• Locate or protect the water heater so it cannot be damaged by a moving vehicle.

E. Exhaust Vent and Intake Pipe

The heater is rated ANSI Z21.10.3 Category IV (pressurized vent, likely to form condensate in the vent) and requires a special vent system designed for pressurized venting.

NOTE: The venting options described here (and further detailed in the Venting section, this manual) are the lone venting options approved for this water heater. Failure to vent the water heater in accordance with the provided venting instructions will void the warranty.

Failure to vent the water heater properly will result in serious personal injury or death.

Figure 1 - Catch Pan Dimensions and Recommended Service Clearances

NOTE: In addition, it is recommended to provide a minimum

service clearance of 6” from the top of the water heater to allow for piping of the T&P relief valve and top ports. Depending on the installation, this clearance may need to be substantially greater than 6”.

NOTE: If you do not provide the minimum clearances shown in Figure 1 it might not be possible to service the heater without removing it from the space.

The space must be provided with combustion / ventilation air openings correctly sized for all other appliances located in the same space as the heater. The heater cover must be securely fastened to prevent the heater from drawing air from the heater room. This is particularly important if the heater is in a room with other appliances. Failure to comply with the above warnings could result in substantial property damage, severe personal injury, or death.

Do not attempt to vent this water heater by any means other than those described in this manual. Doing so will void the warranty and may result in severe personal injury or death. Vents must be properly supported. Heater exhaust and intake connections are not designed to carry heavy weight. Vent support brackets must be within 1’ of the heater and the balance at 4’ intervals. Heater must be readily accessible for visual inspection for rst 3’ from the water heater. Failure to properly support vents could result in property damage, severe personal injury, or death. The exhaust discharged by this water heater may be very hot. Avoid touching or other direct contact with the exhaust gases of the vent termination assembly. Doing so could result in severe personal injury or death.

1. Direct Vent of Exhaust and Intake

If installing a direct vent option, combustion air must be drawn from the outdoors directly into the water heater intake and exhaust must terminate outdoors. There are three basic direct vent options detailed in this manual: 1. Side Wall Venting, 2. Roof Venting, and 3. Unbalanced Venting. Be sure to locate the heater such that the exhaust vent and intake piping can be routed through the building and properly terminated. Dierent vent terminals can be used to simplify and eliminate multiple penetrations in the building structure (see Optional Equipment in Venting Section). The exhaust vent and intake piping lengths, routing, and termination methods must all comply with the methods and limits given in the Venting Section, this manual. When installing a combustion air intake from outdoors, care must be taken to utilize uncontaminated combustion air. To

prevent combustion air contamination, see Table 2.

LP-441 Rev. 3.16.15

Page 9

2. Indoor Combustion Air in Conned or Unconned Space

This heater requires fresh, uncontaminated air for safe operation and must be installed in a mechanical room where there is adequate combustion and ventilating air. NOTE: To

prevent combustion air contamination, see Table 2.

Combustion air from the indoor space can be used if the space has adequate area or when air is provided through a duct or louver to supply sucient combustion air based on the water heater input. Never obstruct the supply of combustion air to the water heater. If the water heater is installed in areas where indoor air is contaminated (see Table 2) it is imperative that the water heater be installed as direct vent so that all combustion air is taken directly from the outdoors into the water heater intake connection. Unconned space is space with volume greater than 50 cubic feet per 1,000 BTU/hr (4.8 cubic meters per kW) of the total input rating of all fuel-burning appliances installed in that space. Rooms connected directly to this space through openings not furnished with doors are considered part of the space. See Venting Section for details. Conned space is space with volume less than 50 cubic feet per 1,000 BTU/hr (4.8 cubic meters per kW) of the total input rating of all fuel-burning appliances installed in that space. Rooms connected directly to this space through openings not furnished with doors are considered part of the space. When drawing combustion air from inside a conventionally constructed building to a conned space, such space should be provided with two permanent openings: one located 6” (15cm) below the space ceiling, the other 6” (15cm) above the space oor. Each opening should have a free area of one square inch per 1,000 BTU/hr (22cm2/kW) of the total input of all appliances in the space, but not less than 100 square inches (645cm2). If the conned space is within a building of tight construction, air for combustion must be obtained from the outdoors as outlined in the Venting section of this manual.

NOTE: DAMAGE TO THE HEATER CAUSED BY EXPOSURE TO CORROSIVE VAPORS IS NOT COVERED BY WARRANTY.

(Refer to the limited warranty for complete terms and conditions.)

G. Removing a Heater from a Common Vent System

Do not install the heater into a common vent with any other appliance. This will cause ue gas spillage or appliance malfunction, resulting in possible substantial property damage, severe personal injury, or death.

When drawing combustion air from the outside into the mechanical room, care must be taken to provide adequate freeze protection.

Failure to provide an adequate supply of fresh combustion air can cause poisonous ue gases to enter the living space, resulting in severe personal injury or death. To prevent combustion air contamination, see Table 2.

F. Prevent Combustion Air Contamination

Install intake air piping for the heater as described in the Venting Section, this manual. Do not terminate exhaust in locations that can allow contamination of intake air.

Ensure that the intake air will not contain any of the contaminants in Table 2. Contaminated air will damage the heater, resulting in possible substantial property damage, severe personal injury, or death. For example, do not pipe intake air near a swimming pool or laundry facilities. These areas always contain contaminants.

Failure to follow all instructions can result in ue gas spillage and carbon monoxide emissions, causing severe personal injury or death.

When removing an existing heater, follow the steps below.

1. Seal any unused openings in the common venting system.

2. Visually inspect the venting system for proper size and horizontal pitch to determine if there is blockage, leakage, corrosion, or other deciencies that could cause an unsafe condition.

3. If practical, close all building doors, windows, and doors between the space in which the water heater remains connected to the common venting system and other spaces in the building. Turn on clothes dryers and any appliances not connected to the common venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, at maximum speed. Do not operate a summer exhaust fan. Close all replace dampers.

4. Place in operation the appliance being inspected. Follow the lighting instructions. Adjust the thermostat so the appliance will operate continuously.

5. Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the ame of a match or

LP-441 Rev. 3.16.15

Page 10

candle or smoke from a cigarette.

6. After it has been determined that each appliance remaining connected to the common venting system properly vents when tested as outlined, return doors, windows, exhaust fans, replace dampers, and any other gas burning appliances to their previous condition of use.

7. Any improper operation of the common venting system should be corrected to conform to the National Fuel Gas Code, ANSI Z223.1. When resizing any portion of the common venting system, the system should approach the minimum size as determined using the appropriate tables in Appendix G of ANSI Z223.1.

Figure 2 - CO Warning Label

H. Water Chemistry Requirements

Chemical imbalance of the water supply may aect eciency and cause severe damage to the water heater and associated equipment. HTP recommends having water quality professionally analyzed to determine whether it is necessary to install a water softener. It is important that the water chemistry on both the domestic hot water and central heating sides are checked before installing the water heater, as water quality will aect the reliability of the system. In addition, operating temperatures above 135oF will further accelerate the build-up of lime scale and may shorten the service life of the water heater. Failure of a water heater due to lime scale build-up, low pH, or other chemical imbalance IS NOT covered by the warranty.

Outlined below are water quality parameters that need to be met in order for the system to operate eciently for many years.

Water Hardness

Water hardness is mainly due to the presence of calcium and magnesium salts dissolved in water. The concentration of these salts is expressed in mg/L, ppm, or grains per gallon as a measure of relative water hardness. Grains per gallon is the common reference used in the US water heater industry. Hardness expressed as mg/L or ppm may be divided by 17.1 to convert to grains per gallon. Water may be classied as very soft,

slightly hard, moderately hard, or hard based on its hardness number. The minerals in the water precipitate out as the water is heated and cause accelerated lime scale accumulation on a heat transfer surface. This lime scale build-up may result in premature failure of the water heater. Operating temperatures above 135oF will further accelerate the build-up of lime scale and may shorten the service life of the water heater. Water that is classied as hard and very hard must be softened to avoid water heater failure.

CLASSIFICATION MG/L OR PPM GRAINS/GAL

Soft 0 - 17.1 0 - 1

Slightly Hard 17.1 - 60 1 - 3.5

Moderately Hard 60 - 120 3.5 - 7

Hard 120 - 180 7 - 10.5

Very Hard 180 and over 10.5 and over

If the hardness of the water exceeds the maximum level of 7 grains per gallon, the water should be softened to a hardness level no lower than 5 grains per gallon. Water softened as low as 0 to 1 grain per gallon may be under-saturated with respect to calcium carbonate, resulting in water that is aggressive and corrosive.

pH of Water

pH is a measure of relative acidity, neutrality, or alkalinity. Dissolved minerals and gases aect water pH. The pH scale ranges from 0 to 14. Water with a pH of 7 is considered neutral. Water with pH lower than 7 is considered acidic. Water with a pH higher than 7 is considered alkaline. A neutral pH (around

7) is desirable for most potable water applications. Corrosion

damage and tank failures resulting from water pH levels of lower than 6 or higher than 8 ARE NOT covered by warranty. The ideal pH range for water used in a water heater

is 7.2 to 7.8.

Total Dissolved Solids

Total Dissolved Solids (TDS) is a measurement of all minerals and solids dissolved in a water sample. The concentration of TDS is usually expressed in parts per million (ppm). Water with a high TDS concentration will greatly accelerate lime and scale formation in the hot water system. Most high TDS concentrations precipitate out of the water when heated. This can generate a scale accumulation that will greatly reduce the service life of the water heater.

The manufacturer of the water heater has no control over water quality, especially TDS levels in your system. TDS in excess of 2000 ppm will accelerate lime and scale formation on the element or the heat exchanger. Water heater failure due to TDS in excess of 2000 ppm IS NOT covered by warranty.

Failure of a water heater due to lime scale build-up IS NOT covered by warranty.

supply line per local codes.

Do not apply heat to the Hot or Cold water heater connections. If sweat connections are used, sweat tubing to the adapter before tting adapter to the water connections on the heater. Any heat applied to the water heater connections will permanently damage the dip tube and/or heat traps. Damages due to improper installation practices ARE NOT covered by warranty.

A. Heater Plumbing

Use two wrenches when tightening water piping at heater. Use one wrench to prevent the heater return or supply line from turning. Failure to prevent piping connections from turning could cause damage to heater components. The heater control module uses temperature sensors to provide both high limit protection and modulating temperature control. The control module also provides low water protection by sensing the water level in the tank. Some codes / jurisdictions may require additional external controls.

Installing the Optional High Output Cold Water Dip Tube - For longer hot water draw, remove the factory installed dip tube from the cold water inlet and replace with the Optional High Output Cold Water Dip Tube. This can be done by hand.

The domestic water connections must be installed in accordance to all local and national plumbing codes, or any applicable standard which prevails. The inlet (cold) and outlet (hot) ports are 3/4” on all models. It is recommended to install a sweat shut-o valve and a union in the cold inlet piping and hot outlet to ease future servicing. If there is a backow preventer or any type of a no return valve in the system, install an additional tee here, suitable for a potable hot water expansion tank. In the hot outlet, install a suitable adapter to match the copper tubing of the plumbing system. A thermal trap or heat trap loop may be installed here to provide additional energy savings and prevent the thermal siphoning of domestic hot water.

B. Auxiliary Connections

The auxiliary connections are additional connections for a recirculation connection, air handlers, plate exchangers, or other devices that supply hot water. These connections must be installed in accordance with all local and national codes or any applicable standard that prevails. Auxiliary connections are 3/4” on all models. Never use dielectric unions or galvanized steel ttings. Use only copper or brass ttings. Sealant must be used on all connections.

Never connect auxiliary connections to any system that uses glycol or other solutions formulated for hydronic systems. These auxiliary connections are to be used only in a potable water system. Failure to follow this warning could result in serious injury or death.

C. Backow Preventer

Use a backow preventer specically designed for water heater installations. This valve should be installed on the cold water ll

D. Potable Expansion Tank

A potable hot water expansion tank is required to oset heated water expansion. In most city plumbing systems, the water meter has a no return or back ow device built into the system to prevent back owing of water into city mains. Some local codes require back ow preventers on all incoming water supplies. The hot water expansion tank must be listed for potable water use. The expansion tank should be located on the cold inlet piping close to the water heater.

Expansion Tank and Make-Up Water

1. Ensure that the expansion tank is sized to correctly handle heater and system water volume and temperature.

Undersized expansion tanks cause system water to be lost from the relief valve, causing make-up water to be added. Eventual heater failure can result due to excessive makeup water addition. SUCH FAILURE IS NOT COVERED BY

WARRANTY.

The expansion tank must be suitable for hot potable water systems.

2. The expansion tank must be located as shown in Applications, this manual, or following recognized design methods. See expansion tank manufacturer’s instructions for details.

E. Temperature and Pressure Relief Valve

Overheated water and high pressures can cause water tank explosion. A properly sized temperature and pressure relief valve must be installed in the opening provided on the water heater. Failure to install a properly sized temperature and pressure relief valve could result in explosion and property damage, serious injury, or death. To avoid water damage or scalding due to relief valve operation:

• Discharge line must be connected to relief valve outlet and run to a safe place of disposal. Terminate the discharge line in a manner that will prevent possibility of severe burns or property damage should the relief valve discharge.

• Discharge line must be as short as possible and the same size as the valve discharge connection throughout its entire length.

• Discharge line must pitch downward from the valve and terminate at least 6” above the oor drain, making discharge clearly visible.

• The discharge line shall terminate plain, not threaded, with a material serviceable for temperatures of 375oF or greater.

• Do not pipe discharge to any location where freezing could occur.

• No valve may be installed between the relief valve and heater or in the discharge line. Do not plug or place any obstruction in the discharge line.

• Test the operation of the relief valve after lling and pressurizing the system by lifting the lever. Make sure the valve discharges freely. If the valve fails to operate

LP-441 Rev. 3.16.15

Page 13

correctly, immediately replace with a new properly rated relief valve.

• Test T&P valve at least once annually to ensure the waterway is clear. If valve does not operate, turn the heater “o” and call a plumber immediately.

• Take care whenever operating relief valve to avoid scalding injury or property damage.

FAILURE TO COMPLY WITH THE ABOVE GUIDELINES COULD RESULT IN FAILURE OF RELIEF VALVE OPERATION, RESULTING IN POSSIBILITY OF SUBSTANTIAL PROPERTY DAMAGE, SEVERE PERSONAL INJURY, OR DEATH.

Do not thread a cap or plug into the relief valve or relief valve line under any circumstances! Explosion and property damage, serious injury, or death may result.

RE-INSPECTION OF T&P RELIEF VALVES: T&P valves should be inspected AT LEAST ONCE EVERY THREE YEARS, and replaced if necessary, by a licensed plumbing

contractor or qualied service technician to ensure that the product has not been aected by corrosive water conditions and to ensure that the valve and discharge line have not been altered or tampered with illegally. Certain naturally occuring conditions may corrode the valve and its components over time, rendering the valve inoperative. Such conditions can only be detected if the valve and its components are physically removed and inspected. Do not attempt to conduct an inspection on your own. Contact your plumbing contractor for a re-inspection to assure continued safety.

FAILURE TO RE-INSPECT THE T&P VALVE AS DIRECTED COULD RESULT IN UNSAFE TEMPERATURE AND/OR PRESSURE BUILD-UP WHICH CAN RESULT IN PROPERTY DAMAGE, SERIOUS PERSONAL INJURY, OR DEATH.

time with regard to scald injury and may be used as a guide in determining the safest water temperature for your applications.

An ASSE 1017 or ASSE 1070 temperature limiting or mixing valve is recommended in installations servicing disabled or elderly persons, or children. Mixing valves do not eliminate the risk of scalding. To avoid scalding:

• Set the water heater set point temperature as low as possible.

• Feel water before bathing or showering.

• If thermostatic valves are required, use devices specically designed for such purpose. Install these devices in accordance with instructions provided by the manufacturer.

Failure to install a temperature limiting or mixing valve and follow these instructions could result in property damage, severe personal injury, or death due to scalds.

Approximate Time / Temperature Relationships in Scalds

120oF More than 5 minutes

125oF 1 1/2 to 2 minutes

130oF About 30 seconds

135oF About 10 seconds

140oF Less than 5 seconds

145oF Less than 3 seconds

150oF About 1 1/2 seconds

155oF About 1 second

G. Filling the Heater

F. Scalding

This water heater can deliver scalding water. Be careful whenever using hot water to avoid scalding injury. Certain appliances such as dishwashers and automatic clothes washers may require increased water temperatures. By setting the thermostat on this heater to obtain the increased water temperature required by these appliances you may create the potential for scald injury.

To protect against injury, install a mixing valve in the water system. This valve will reduce point of use discharge temperatures by mixing cold and hot water in branch supply lines. Such valves are available from your local plumbing supplier.

Table 4 details the relationship of water temperature and

The water heater must be full of water and the system fully purged BEFORE powering the water heater. When lling the water heater, open a hot water tap to release air in the tank and piping. All air has been purged from the system when water runs freely from the faucets. Applying power to the water heater when it is not full of water will damage the heat exchanger, and could result in property damage, serious personal injury, or death. Such damages ARE NOT covered by water heater warranty.

• Make certain the drain valve is completely closed.

• Open the shut-o valve in the cold water supply line.

• Open the hot water faucets to allow air to vent from the heater and piping.

• Allow sucient time for the heater to completely ll with water.

Part 5 - Venting and Condensate Removal

The heater must be vented as detailed in this section. Ensure exhaust vent and intake piping complies with these instructions regarding vent system. Inspect nished exhaust vent and intake piping thoroughly to ensure all joints are well secured, airtight, and comply with all applicable code requirements, as well as the instructions provided in this manual. Failure to properly install the vent system will result in severe personal injury or death.

A. General

This heater is certied as a “Category IV” appliance and requires a special venting system. The vent system will operate with a positive pressure in the pipe. Exhaust gases must be piped directly outdoors using the vent materials and rules outlined in these instructions. Do not connect vent connectors serving appliances vented by natural draft into any portion of mechanical draft systems operating under positive pressure. Follow the venting instructions carefully. Failure to do so will result in substantial property damage, severe personal injury, or death.

1. Installation should be made in accordance with the regulations of the Authority Having Jurisdiction, local code authorities, and utility companies which pertain to this type of water heating equipment.

2. Install the venting system in accordance with these instructions and with the National Fuel Gas Code, ANSI Z223.1/ NFPA 54, CAN/CGA B149, and / or applicable provisions of local building codes.

3. This water heater must be vented with materials, components, and systems listed and approved for Category IV appliances.

Exhaust and intake are to be piped separately. This heater cannot share a common exhaust or intake with multiple appliances. Failure to follow these instructions will result in substantial property damage, severe personal injury, or death.

NOTE: To avoid contamination often contained in indoor air, it is best to pipe all intake combustion air directly to the outdoors. NOTE: If exhaust vent pipe system passes through an unheated space such as an alcove or attic, the space must be heated or the pipe must be insulated. The insulation must have an R value sucient to prevent freezing of the condensate.

Improper seating of vent pipe gaskets can cause eventual gasket failure and exhaust gas leakage. Ensure the exhaust vent pipe is properly beveled and seated before insertion into the ue adapter. Failure to do so could result in property damage, severe personal injury, or death.

Due to the extreme ammability of most glues, cements, solvents, and primers used to join plastic exhaust vent and intake pipes, explosive solvent vapors must be cleared from all vent piping before start-up. Avoid using excess cement or primer, as this may pool in the vent pipes. Vent assemblies should be allowed to cure for a period of at least 8 hours before powering a connected appliance. Failure to follow these instructions will result in substantial property damage, severe personal injury, or death. It is the installers’ responsibility to understand the hazards associated with explosive solvents and take the necessary precautions to avoid these risks.

DO NOT insulate the rst 3 feet of the exhaust vent. CPVC, Polypropylene, or Stainless Steel pipe material MUST be used for the rst 3 feet of the vent run if the exhaust vent is insulated or passes through an enclosed space greater than 6”, such as a wall. The balance of the vent run can be installed with standard Schedule 40 PVC pipe. Failure to comply with this warning could result in property damage, severe personal injury, or death. Exhaust vent adaptors are not designed as load-bearing devices, and must not be used to support exhaust vent piping. All vent pipes must be properly connected, supported, and the exhaust vent must be pitched a minimum of 1/4” per foot back to the heater to allow drainage of condensate. Failure to properly support vent piping and follow the information in this statement could result in product damage, severe personal injury, or death.

Provide 4 feet horizontal clearance from electrical meters, gas meters, gas regulators, relief equipment, exhaust fans and inlets. In no case shall the exit terminal be above or below the aforementioned equipment unless the 4 foot horizontal distance is maintained. J. This water heater vent system shall terminate at least 3 feet (0.9 m) above any forced air intake located within 10 ft (3 m). NOTE: This does not apply to the combustion air intake of a directvent appliance. K. When venting with a two pipe system, maximum distance between exhaust vent and intake pipe is 6 feet (1.8 m). Minimum distance between exhaust vent and intake pipe on single direct vented appliance is 10” (0.255 m) center-to-center. Minimum distance between exhaust vents and intake pipes on multiple water heaters is 10” (0.255 m) center-to-center. L. When adjacent to a public walkway, locate exit terminal at least 7 feet above grade.

In addition:

• Total length of vent piping shall not exceed the limits specied in this manual.

• The vent piping for this direct vented appliance is approved

for zero clearance to combustible construction.

• The ue products coming from the exhaust vent will create

a large plume when the heater is in operation. Avoid venting in areas that will aect neighboring buildings or be considered objectionable.

• DO NOT locate exhaust vent or intake pipe in a parking area

where machinery may damage the pipe.

• DO NOT locate the exhaust vent or intake pipe terminals

under a porch, balcony, or veranda.

• Avoid terminating exhaust vents near shrubs, air condition-

ers, or other objects that will obstruct the exhaust stream.

• DO NOT vent over a public walkway. Condensate could drip

or freeze and create a nuisance or hazard.

• NOTE: Due to potential moisture build-up, sidewall venting

may not be the preferred venting option. Carefully consider venting installation and location to save time and cost.

INSTALLATIONS IN CANADA NOTE: Canadian installation must comply with the CAN/CSA B149.1

code and applicable local codes and supersede the restrictions for the United States outlined in this section.

The building owner is responsible for keeping the exhaust and intake terminations free of snow, ice, or other potential blockages, as well as scheduling routing maintenance. Failure to keep the vent piping terminations clear and properly maintain the heater could result in property damage, severe personal injury, or death. For each oor containing bedroom(s), a carbon monoxide detector and alarm shall be placed in the living area outside the bedrooms, as well as in the room that houses the heater. Detectors and alarms shall comply with NFPA 720 (latest edition). Failure to comply with these requirements could result in product damage, severe personal injury, or death.

E. Exhaust Vent and Intake Pipe Sizing

1. The exhaust vent and intake pipe size is 2”.

LP-441 Rev. 3.16.15

Page 19

2. The total equivalent length of exhaust vent and intake pipe should not exceed 150 feet.

a. The equivalent length of elbows, tees, and other ttings are listed in the Friction Loss Table.

Friction Loss Equivalent in Piping and Fittings

Fittings or Piping

90 Degree Elbow* 5’ 5’

45 Degree Elbow 3’ 3’

Table 6 - *Friction loss for long radius elbow is 1 foot less. NOTE: Consult Polypropylene venting instructions for friction loss and pressure drop equivalents.

Equivalent Feet

2” 3”

b. For example: If the exhaust vent has two 90o elbows and 10 feet of PVC pipe we will calculate: Exhaust Vent Equivalent Length = (2x5) + 10 = 20 feet. Further, if the intake pipe has two 90o elbows, one 45o elbow, and 10 feet of PVC pipe, the following calculation applies: Intake Pipe Equivalent Length = (2x5) + 3 + 10 = 23 feet. Finally, if a concentric kit is used we nd: Total Equivalent Length = 20 + 23 + 3 = 46 feet. The total equivalent length is 46 feet, well below the maximum of 150 feet. c. Eort should be made to keep a minimum dierence in equivalent length between the exhaust vent and intake pipe.

3. The minimum total equivalent length is 16 feet.

Do not exceed the maximum lengths for vent pipes. Excessive length could result in heater shutdown and property damage.

Failure to provide a minimum total vent length of 16 equivalent feet could result in property damage and improper product operation.

F. Longer Vent Runs

The maximum total equivalent length can be extended by increasing the diameter of both the exhaust vent and intake pipes. However, the transitions should begin a minimum of 15 equivalent feet from the water heater.

a. The maximum total equivalent length for increased

diameter vent pipes is 200 feet.

b. Transitions should always be made in vertical sections of pipe to prevent the condensate from pooling in the vent pipe.

Vent Connection Reducing Coupling Vent Transition

2” 3” x 2” 3”

Table 7 - Vent Run Transition

c. Transition from 2” to 3” pipe should be made at the water heater.

G. Exhaust Vent and Intake Pipe Installation

All joints of positive pressure vent systems must be sealed completely to prevent leakage of ue products into the living space. Failure to do so could result in property damage, serious injury, or death.

1. Use only solid PVC or CPVC pipe or a Polypropylene vent system approved for use with Category IV appliances. FOAM CORE PIPING IS NOT APPROVED FOR EXHAUST VENT APPLICATIONS. Foam core piping may be used on air inlet piping only.

2. Remove all burrs and debris from joints and ttings.

3. When using PVC or CPVC pipe, all joints must be properly cleaned, primed, and cemented. Use only cement and primer approved for use with the pipe material. Cement must conform to ASTM D2564 for PVC and ASTM F493 for CPVC pipe. NOTE:

DO NOT CEMENT POLYPROPYLENE PIPE.

4. Ensure the vent is located where it will not be exposed to prevailing winds.

5. In all roof venting applications, exhaust discharge must point away from the pitch of the roof.

6. To prevent water leakage, install adequate roof ashing where the pipe enters the roof.

7. Do not locate vent over public walkways, driveways, or parking lots. Condensate could drip and freeze, resulting in a slip hazard or damage to vehicles and machinery.

8. Due to potential moisture build-up, sidewall venting may not be the preferred venting option. To save time and cost, carefully consider venting installation and location.

9. Horizontal lengths of exhaust vent must slope back towards the water heater not less than ¼” per foot to allow condensate to drain from the vent pipe.

10. The exhaust vent must terminate where vapors cannot make accidental contact with people or pets, or damage shrubs or plants.

11. In vacant chimney applications, install and seal a rain cap over existing chimney openings.

12. All piping must be fully supported. Use pipe hangers at a minimum of 4 foot intervals to prevent sagging of the pipe where condensate may form.

13. Do not use the heater to support any piping.

14. A screened straight coupling is provided with the heater for use as an outside exhaust termination.

15. A screened inlet air tee is provided with the heater to be used as an outside intake termination. The following table lists optional exhaust/intake terminations available from HTP:

H. Applications

1. Direct Vent Installation of Exhaust and Intake

If installing a direct vent option, combustion air must be drawn from the outdoors directly into the water heater intake, and exhaust must terminate outside. There are three basic direct vent options detailed in this manual: 1. Side Wall Venting, 2. Roof Venting, and 3. Unbalanced Venting. Be sure to locate the heater such that the exhaust vent and intake pipe can be routed through the building and properly terminated. Dierent vent terminals can be used to simplify and eliminate multiple penetrations in the building structure (see Optional Equipment in Venting Section). The exhaust vent and intake pipe lengths, routing and termination methods must all comply with the methods and limits given in the Venting section of this manual. When installing a combustion air intake from outdoors, care must be taken to utilize uncontaminated combustion air. NOTE: To prevent combustion air contamination, see Table 2.

Take extra precaution to adequately support the weight of vent pipes terminating through the roof. Failure to properly support roof terminated piping could result in property damage, serious injury, or death.

NOTE: These drawings are meant to demonstrate system

venting only. The installer is responsible for all equipment and detailing required by local codes.

All vent pipes must be glued, properly supported, and the exhaust pitched a minimum of 1/4” per foot back to the heater to allow drainage of condensate. When placing support brackets on vent piping, the rst bracket must be within 1 foot of the water heater and the balance of 4 foot intervals on the vent pipe. Venting must be readily accessible for visual inspection from the rst three feet from the heater.

Figure 10 - Horizontal (Snorkel) Venting NOTES:

A. For every 1” of overhang, the exhaust vent must be located 1” vertical below overhang (overhang means top of building structure and not two adjacent walls [corner of building]). B. Typical installations require 12” minimum separation between bottom of exhaust outlet and top of air intake. C. Maintain 12” minimum clearance above highest anticipated snow level or grade (whichever is greater). D. Minimum 12” between vents when installing multiple vents.

E. 12” minimum beyond air intake.

Do not install the heater into a common existing vent with any other appliance. This will cause ue gas spillage or heater malfunction, resulting in substantial property damage, serious personal injury, or death.

Contractors must check state and local codes before installing through an existing vent opening. State and local codes always take precedence over manufacturer’s instructions. Failure to check state and local codes before installing through an existing opening could result in property damage and add signicantly to installation costs.

If an existing venting system is converted for use with this heater, the installer must ensure that the existing venting system is clean and free from particulate contamination that could damage the heater. Failure to do so could result in property damage and heater failure. Such failure IS NOT covered under warranty.

Concentric Venting Through an Existing System

NOTE: The following instructions refer only to venting through an existing vent system, and not to venting with HTP’s optional concentric vent kits. Refer to Concentric Vent Kit installation manual (LP-166) for further information on venting with the

3. Indoor Combustion Air in Conned or Unconned Space

This heater requires fresh, uncontaminated air for safe operation and must be installed in a mechanical room where there is adequate combustion and ventilating air. NOTE: To

prevent combustion air contamination, see Table 2.

Figure 12 - 1, 2 - Concentric Venting Through an Existing System, 3, Chase Venting Through an Existing System NOTE: These drawings are meant to demonstrate system venting only. The installer is responsible for all equipment and detailing required by

local codes.

optional concentric vent kits. Concentric venting through an existing system must run vertically through the roof. See Table 9 for proper minimum vent sizing. Use only the approved venting materials specied in Table 5 for piping the system. All instructions listed in this Venting section apply. See Figures 12-1 and 12-2 for venting demonstrations.

The upper and lower vent terminations as well as all joints in the venting system must be properly sealed to ensure that all combustion air is drawn properly and exhaust does not leak from the system. Failure to properly seal the venting system will result in property damage, serious personal injury, or death.

Chase Venting Through an Existing System

When venting as a chase, follow all instructions included in this Venting section, including those in the previous Concentric Venting Through an Existing System section. See Figure 12-3 for chase venting demonstration.

LP-441 Rev. 3.16.15

openings not furnished with doors, are considered part of the space. Conned space is space with volume less than 50 cubic feet per 1,000 Btu/hour (4.8 cubic meters per kW) of the total input rating of all fuel-burning appliances installed in that space. Rooms connected directly to this space, through openings not furnished with doors, are considered part of the space. When drawing combustion air from inside a conventionally constructed building to a conned space, such space should be provided with two permanent openings: one located 6” (15 cm) below the space ceiling, the other 6” (15cm) above the space oor. Each opening should have a free area of one square inch per 1,000 Btu/hr (22cm2/kW) of the total input of all appliances in the space, but not less than 100 square inches (645cm2). If the conned space is within a building of tight construction, air for combustion must be obtained from the outdoors as outlined in the Venting section of this manual. See Figure 13.

I. Condensate Removal System

NOTE: Check with your local gas company to determine if combustion condensate disposal is permitted in your area. In the state of Massachusetts, condensate must be neutralized before entering a drain. This condensing high eciency water heater has a condensate removal system. Condensate is water vapor derived from combustion products, similar to that produced by an automobile when it is initially started. It is very important that the condensate line is sloped down away from the heater and to a suitable drain. If the heater condensate outlet is lower than the drain, you must use a condensate removal pump (kit p/n 554200 available from HTP). If required by local authorities, a condensate lter of lime crystals, marble, or phosphate chips will neutralize slightly acidic condensate.

The condensate line must remain unobstructed. If allowed to freeze in the line or obstructed in any other manner, condensate can exit from the water heater tee, resulting in potential water damage to property. When installing a condensate pump, select one approved for use with condensing heaters and furnaces. The condensate pump should have an overow switch to prevent property damage from spillage. Condensate from the heater will be slightly acidic (pH from 3.2 to 4.5). Install a neutralizing lter if required by local codes.

Figure 14 - Indoor and Outdoor Combustion Air - Single Pipe

Power to the optional condensate pump is continuous. When the water heater is powered o the condensate pump will remain on. It is important to remember to turn o the condensate pump when powering down the water heater. Failure to do so could result in property damage, severe personal injury, or death.

LP-441 Rev. 3.16.15

Page 24

Figure 15 - Condensate Piping NOTES:

1. Condensate line must be pitched at least ¼” per foot to properly drain. If this cannot be done, or a very long length of condensate hose is used, increase the condensate line to a minimum of 1” ID and place a tee in the line after the condensate neutralizer to properly reduce vacuum lock in the drain line.

2. PVC or CPVC pipe should be the only material used for condensate line. Steel, brass, copper, and other metals will be subject to corrosion or deterioration.

3. A frozen condensate line could result in a blocked vent condition. It is very important to protect the condensate line from freezing temperatures or any type of blockage. In installations that may encounter sustained freezing conditions, the use of heat tape is recommended to avoid freezing of the condensate line. It is also recommended to bush up the condensate line size to 1” and terminate condensate discharge as close to the unit as possible. Longer condensate runs are more prone to freezing. Damages due to frozen or blocked condensate lines ARE NOT covered by warranty.

4. Support of the condensate line may be necessary to avoid blockage of the condensate ow.

To ensure proper condensate neutralization it is recommended to check the condensate neutralizer cartridge every two years. Gently shake the cartridge to ensure it is still lled with neutralization media. Replace the condensate neutralizer cartridge if it is empty. Failure to do so could result in improper condensate neutralization. Please note that if not properly neutralized the slightly acidic condensate could corrode

materials subject to corrosion (metals, concrete, stonework, etc.)

Part 6 - Wiring

To avoid electrical shock, turn o all power to the heater prior to opening an electrical box within the unit. Ensure the power remains o while any wiring connections are being made. Failure to follow these instructions could result in component or product failure, serious injury, or death. Such product failure IS NOT covered by warranty. Jumping out control circuits or components WILL VOID product warranty and can result in property damage, personal injury, or death.

A. Line Voltage Input

The heater must be wired to a 115 volt circuit by a qualied electrician. It is recommended that the heater be wired on its own circuit to minimize the possibility of circuit failure due to outside clauses. The heater requires a maximum of 8 amps at 120 volts in use.

Figure 18 - Low Voltage Wiring

Label all wires prior to disconnecting them when servicing the heater. Wiring errors can cause improper and dangerous operation. Failure to follow these instructions may result in property damage or personal injury.

Figure 17 - Line Voltage Wiring

B. Line Voltage Condensate Input

The heater has the capability of supplying power to a condensate pump. The connection is 115 VAC + 10% / - 15% at a max of 2 amps. Power is supplied to the pump only when the heater is connected to power, and the power switch is in the on position.

C. Low Voltage Outdoor Sensor Input

The heater has the capability of an outdoor reset. Connecting an outdoor sensor allows the heater to operate at optimum eciency. HTP oers an outdoor sensor, p/n 7250P-319. The outdoor sensor must be a 12K NTC sensor. Use a minimum 22 AWG wire for runs of 100 feet or less and minimum 18 AWG wire for runs up to 150 feet. Instructions are included with the outdoor sensor to correctly mount the sensor on the exterior surface of the building. It is preferable to mount the sensor on the north side in an area that will not be aected by direct sunlight but will be exposed to varying weather conditions. Connect the outdoor sensor to terminals marked “Outdoor”.

It is of extreme importance that this unit be properly grounded. It is very important that the building system ground is inspected by a qualied electrician prior to making this connection. Electrical power must only be turned on when the heater is completely lled with cold water. Failure to follow these instructions could result in component or product failure, serious injury, or death.

Failure to follow all precautions could result in re, explosion, severe injury, or death.

Ensure the gas on which the water heater will operate is the same type specied on the rating plate. Failure to do so could result in water heater malfunction, property damage, personal injury, or death.

The gas supply shall have a maximum inlet pressure of less than 14” water column (350 mm), ½ pound pressure (3.5 kPa), and a minimum of 3.5” water column. The entire piping system, gas meter and regulator must be sized properly to prevent pressure drop greater than 0.5” WC as stated in the National Fuel Gas Code. This information is listed on the rating plate. It is very important that you are connected to the type of gas as noted on the rating plate: “LP” for liqueed petroleum, propane gas, or “Nat” for natural or city gas. All gas connections must be

approved by the local gas supplier or utility, in addition to the governing authority, prior to turning the gas supply on. Do not remove the adaptor in Figure 19! It is mandatory that this tting is used for connection to a eld fabricated drip leg per the National Fuel Gas Code. You must ensure that the entire gas line to the connection at the water heater is no smaller than ½”. Once all inspections have been performed, the piping must be leak tested. If the leak test requirement is a higher test pressure than the maximum gas inlet pressure, you must isolate the heater from the gas line to continue leak testing. To do this, you must turn o the factory and eld-installed gas cocks. This will minimize the possibility of damaging the gas valve. Failure to do so may damage the gas valve. In the event the gas valve is exposed to a pressure greater than ½ PSI, 14” water column, the gas valve must be replaced. Never use an open ame (match, lighter, etc.) to check gas connections.

LP-441 Rev. 3.16.15

Page 27

UL recognized fuel gas detectors are recommended in all enclosed propane and natural gas applications where there is a potential for an explosive mixture of fuel gas to accumulate. The installation of these detectors should be made in accordance with the detector manufacturer’s recommendations, and/or local laws. Failure to install fuel gas detectors in these applications could result in re, explosion, property damage, severe personal injury, or death.

Maximum capacity of pipe in cubic feet of gas per hour for gas pressures of .5 psi or less and a pressure drop of .3 inch water column. It is recommended that a soapy solution be used to detect leaks. Bubbles will appear on the pipe to indicate a leak is present. The gas piping must be sized for proper ow and length of pipe to avoid excessive pressure drop. Both the gas meter and the gas regulator must be properly sized for the total gas load. If you experience a pressure drop greater than 1” WC, the meter, regulator or gas line is undersized or in need of service. You can attach a manometer to the incoming gas drip leg by removing the cap. The gas pressure must remain between 3.5” WC and 14” WC during stand-by (static) mode and while in operating (dynamic) mode at full output. If an in-line regulator is used, it must be a minimum of 10 feet from the heater. It is very important that the gas line is properly purged by the gas supplier or utility. Failure to properly purge the lines or improper line sizing will result in ignition failure. This problem is especially noticeable in NEW LP installations and also in empty tank situations. This can also occur when a utility company shuts o service to an area to provide maintenance to their lines. The gas valve must not be replaced with a conventional gas valve under any circumstances. As an additional safety feature, the gas valve in this water heater has a anged connection to the swirl plate and blower.

Figure 20 - Gas Connection

A. Gas Piping

Run the gas supply line in accordance with all applicable codes. Locate and install manual shuto valves in accordance with local and state requirements.

Support gas supply piping with hangers, not by the heater or its accessories. The heater gas valve and blower will not support the weight of the piping. Make sure the gas piping is protected from physical damage and freezing, where required. Failure to follow these instructions could result in gas leakage, and result in re, explosion, property damage, severe personal injury, or death. Do not use Teon tape on gas line pipe thread. Use a pipe compound rated for use with natural and propane gases. Apply sparingly on male pipe ends, leaving the two end threads bare. Failure to follow these instructions could result in gas leakage, and result in re, explosion, property damage, severe personal injury, or death.

Part 9 - Start-Up Procedure

FOR YOUR OWN SAFETY READ BEFORE OPERATING

1. This water heater does not have a pilot. It is equipped with an ignition device which automatically lights the burner. Do not try to light the burner by hand.

2. BEFORE OPERATING: Smell all around the water heater area for gas. Be sure to smell next to the oor because some gas is heavier than air and will settle on the oor.

WHAT TO DO IF YOU SMELL GAS

• Do not try to light any water heater.

• Do not touch any electric switch, do not use any phone in your building.

• Immediately call your gas supplier from a neighbor’s phone. Follow the gas suppliers’ instructions.

• If you cannot reach your gas supplier, call the re department.

• Turn o the gas shuto valve (located outside the water heater) so that the handle is crosswise to the gas pipe. If the handle will not turn by hand, don’t try to force or repair it, call a qualied service technician. Force or attempted repair may result in a re or explosion.

4. Do not use this water heater if any part has been under water. Immediately call a qualied service technician to inspect the water heater and to replace any part of the control system and any gas control that has been damaged.

5. The water heater shall be installed so the gas ignition system components are protected from water (dripping, spraying, rain, etc.) during water heater operation and service (circulator

replacement, condensate trap, control replacement, etc.)

Failure to follow these instructions could result in property

damage, serious personal injury, or death.

A. Operating Instructions

If you smell gas, STOP. Follow listed safety instructions above. If you do not smell gas, follow the next steps.

1. Make sure tank is full with cold water and purge all piping. To assure adequate piping, open all hot water faucets.

Ensure the water heater is full of water before ring the burner. Failure to do so will damage the heater. Such damage IS NOT covered by warranty, and could result in property damage, serious personal injury, or death.

2. Turn on all electric power to water heater.

3. Remove the Front Panel WARNING label.

4. Adjust the temperature set point of the heater to the desired level. The factory default setting is 120oF. If changes are necessary, follow “Basic Control Functions” in this manual.

5. If the water heater fails to start, refer to the Troubleshooting section in the back of this manual.

C. Maintenance

The control system requires no periodic maintenance under normal conditions. However, in unusually dirty or dusty conditions, periodic vacuuming of the cover to maintain visibility of the display and indicators is recommended. In dirty environments, such as construction sites, care must be taken to keep the water heater burner cover in place and drywall or saw dust away from water heater.

In unusually dirty or dusty conditions care must be taken to keep water heater burner door in place. Failure to do so VOIDS warranty.

Allowing the heater to operate with a dirty combustion chamber will hurt operation. Failure to clean the heat exchanger as needed by the installation location could result in heater failure, property damage, personal injury, or death. Such product failures ARE NOT covered under warranty.

Part 10 - Shutdown

A. Shutdown Procedure

If the burner is not operating, lower the set point value to 70oF and wait for the burner to shut o. Continue to wait for the combustion blower to stop, so all latent combustion gases are purged from the system. This should take a maximum of 5 minutes. After combustion gases are purged turn o electrical power to the water heater.

B. Vacation Procedure

If there is danger of freezing, change the set point to 70oF. DO NOT turn o electrical power. If there is no danger of freezing, follow “Shutdown Procedure”.

C. Failure to Operate

Should the burner fail to light, the control will perform two more ignition trials prior to entering a lockout state. Note that each subsequent ignition trial will not occur immediately. After a failed ignition trial, the blower must run for approximately 10 seconds to purge the system. Therefore, a time period of approximately 40 to 90 seconds will expire between each ignition trial. If the burner lights during any one of these three ignition trials, normal operation will resume. If the burner lights, but goes o in about 4 seconds, check the polarity of the wiring. See electrical connection section of this manual. If the burner does not light after the third ignition trial, the control will enter a lockout state. This lockout state indicates that a problem exists with the water heater, the controls, or the gas supply. Under such circumstances, a qualied service technician should be contacted immediately to properly service the water heater and correct the problem.

LP-441 Rev. 3.16.15

Page 34

If a technician is not available, pressing the button will remove the lockout state so additional trials for ignition can be performed.

D. Important Notice

It is extremely important that whenever work is performed on the plumbing system that either:

• The water heater is powered o, or,

• The water heater is valved o and isolated from the plumbing system.

Failure to take these measures could result in a dry-ring condition.

The water heater must be full of water and the system fully purged BEFORE powering the water heater. Performing any work in the plumbing system without either powering o the water heater or isolating the water heater through the use of shut-o valves could result in a condition referred to as “dry-ring”. Dry-ring the water heater will damage the heat exchanger, and could result in property damage, serious personal injury, or death. Such damages ARE NOT covered by water heater warranty.

Part 11 - Troubleshooting

A. Error Code

An error code may occur during installation of the heater. This condition may lead to a lock out condition of the controller,

which will need to be manually reset by pressing the button.

B. Heater Error

1. When an error condition occurs the controller will display an error code on the display module.

2. These error codes and several suggested corrective actions are included in Table 16.

3. In the case of E07 and E13 error codes, if uncorrected, the water heater will go into a fault condition as described in section C. Lockout.

C. Lockout

1. When an fault condition occurs, the controller will display a fault code (example: F00 on the display module).

2. Note the fault code and refer to Table 17 for an explanation of the fault code along with several suggestions for corrective actions.

3. Press the button to clear the fault and resume operation. Be sure to observe the operation of the unit to prevent a recurrence of the fault. NOTE: You are allowed up to 5 “resets” to clear fault or error codes. After that, the controller will enter an E13 lockout state.

When servicing or replacing any components of this water heater be certain that:

• The gas is o.

• All electrical power is disconnected. In addition, when servicing or replacing components of this water heater in direct contact with heater water:

• There is no pressure in the heater. Pull the release on

the relief valve to relieve pressure in the heater.

• Heater water is not hot. Failure to follow these precautions could result in property damage, serious personal injury, or death. Such damages ARE NOT covered by water heater warranty.

DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN SUBMERGED IN WATER. Immediately call a qualied service

technician. The appliance MUST BE replaced if it has been submerged. Attempting to operate an appliance that has been submerged could create numerous harmful conditions, such as a potential gas leakage causing a re and/or explosion, or the release of mold, bacteria, or other harmful particulates into the air. Operating a previously submerged appliance could result in property damage, severe personal injury, or death. NOTE: Appliance damage due to ood or submersion is considered an Act of God, and IS NOT covered under product warranty.

The water heater has wire function labels on all internal wiring. Observe the position of each wire before removing it. Wiring errors may cause improper and dangerous operation. Verify proper operation after servicing.

In unusually dirty or dusty conditions, care must be taken to keep water heater cabinet door in place at all times. Failure to do so VOIDS the warranty.

Allowing the water heater to operate with a dirty combustion chamber will hurt operation. Failure to clean the heat exchanger as needed by the installation location could result in water heater failure, property damage, personal injury, or death. Such product failures ARE NOT covered under warranty.

Hydrogen gas can build up in a hot water system served by this water heater that has not been used for a long period of time (generally two weeks or more). When opening a hot water faucet in a system that has been out of use for a time, keep all ignition sources (electrical appliances, open ame, etc.) away from the faucet. If hydrogen is present, there will be a sound of air escaping as water begins to ow. Allow the water to run for a few minutes to dissipate built up hydrogen from the system. Failure to follow these instructions can result in property damage, personal injury, or death.

The water heater requires minimal periodic maintenance under normal conditions. However, in unusually dirty or dusty conditions, periodic vacuuming of the cover to maintain visibility
