Enclosure models and arrangements

Regency

FF5/FF3 - Front grille

Applications:

Provide heat through front panel louvers when installations require heated air to be diffused away from exterior walls.

FR5/FR3 - Rounded grille

Applications:

When high heat output is demanded into room and along exterior walls. Appealing enclosure design allows heat to radiate through louvers rounded along top and front edge of cabinet.

FT5/FT3 - Top grille

Applications:

Provide an even blanket of heated air through top louvers and emit radiant heat off the front of the cabinet. Ideal for exposed walls and large window areas.

FS5/FS3 - Sloped grille

Applications:

Designed for high heat output through a sloped louvered outlet.

Recommended to prevent enclosure from being used as shelf or step.

FSOS - Double sloped grille

Applications:

Double sloped panels provide required heat output when higher wall mounting is called for to restrict accessibility...such as in swimming pool areas and gymnasiums.

ETL - Pedestal

Applications:

When wall mounting is not an option, these models can be secured directly to the floor. Ceiling to floor windows would necessitate using this style of enclosure.

Econoline

STEL - Sloped economy

Applications:

Econo-Line sloped top baseboard enclosures from

Zehnder Rittling are an excellent choice for light commercial applications such as banks, offices, hospitals and housing renovations.

Econo-Line is designed to provide high heat output through a sloped louvered grilled. The enclosures can accommodate eight types of Zehnder Rittling copper/ aluminum finned tube with nominal diameters of 3/4, 1 or 1-1/4 inches, fins measuring 2-3/4 by 4 inches and fin spacing of 32, 40 or 48 per foot.

Enclosure sections are available in 15 lengths from 1 through 8 feet in 6 inch increments for a custom fit.

ETO and EXO - Economy

Applications:

For use with one, two, or three vertical rows of wall mounted finned tube.

ETO (top-louvered outlet) and EXO (expanded metal) enclosures slip securely over one, two or three vertical rows of wall-mounted finned tube. The tube is set in place in Zehnder Rittling’s universal, cradle-type expansion brackets and lagged to the wall at the desired height.

Made of sturdy, ribbed galvanneal steel, these economical brackets permit 1-1⁄4 inches of finned tube expansion and are installed at intervals of 36 inches or less.

Featured in ETO and EXO enclosures, they accommodate any Zehnder Rittling finned tube with fins measuring

3-1⁄4" x 3-1⁄4" or 4-1⁄4" x 4-1⁄4".

(See our Finned Tube catalog for more information).

Design data

The effects of water velocity on finned tube output

The Institute of Boiler and Radiator Manufacturers sponsored a test program at the University of Illinois to determine the effect of water velocity on heat output of various sizes of finned tubed element.

The results of this test show that when the water velocity falls below 0.4 f.p.s., the flow changes from turbulent to streamline. With systems designed at water velocities below this point the output cannot be accurately predicted so should always be avoided.

Figure 1 shows rating factors that can be utilized when the water velocity falls below 3 f.p.s.

It is recommended when designing low-load systems that the water velocity be a key factor in element selection.

General information

This installation and startup instructions literature is for Rittling Finned Tube and

Enclosures. Designed for yearround heating, your equipment is initially protected under the

Zehnder Rittling standard one-year warranty provided the steps outlined in this manual for initial inspection, installation, periodic maintenance and normal every day operation of the equipment are followed.

This manual should be thoroughly reviewed prior to the installation, start-up or maintenance of the equipment. If any questions arise, please contact your local Zehnder Rittling sales representative or the factory before proceeding any further.

Receiving

Upon delivery, examine the shipment against the bill of lading to make sure all of the equipment has been received and then check each piece carefully for shipping damage.

Any damage should be reported to the freight carrier and a claim should be filed with them. Ensure the shipping company makes proper notation of any shortages or damage on all copies of the freight bill. Concealed damage not discovered during unloading must be reported to the shipping company within 15 days of receipt of the shipment. After inspection, return each enclosure to its carton until ready for installation.

All pieces are shipped F.O.B. factory.

Therefore, Zehnder Rittling is not responsible for damage during transit. It is the responsibility of the installing contractor to inspect and verify that the pieces shipped were in fact the correct model number, length, height, etc. Any discrepancies should be reported to the local Sales Representative for immediate resolution prior to unpackaging and installation. The factory should be notified of any warranty repairs required in writing before any corrective action is taken.

The factory must be fully informed of the expected costs before the work is begun. Zehnder Rittling is not responsible for any repairs or alterations made by the purchaser without Zehnder Rittling’s written consent and will not accept any back charges associated with these repairs or alterations. The return of damaged equipment will not be accepted without written authorization from Zehnder

Rittling.

An enclosure that has received a written Return Goods

Authorization will be inspected by Zehnder Rittling upon receipt. Any damage, missing parts, reworking or repackaging resulting from prior installation will constitute just cause for

Zehnder Rittling to issue partial credit.

Safety considerations

The installation of Rittling

Finned Tube, Enclosure and all associated components, parts and accessories which make up the installation, shall be in accordance with the regulations of all authorities having jurisdiction and must conform to all applicable codes. Only trained and qualified service personnel using good judgment and safe practices should install, repair and/or service air conditioning equipment.

Untrained personnel can perform basic maintenance functions such as cleaning the heat transfer surfaces or enclosures. When working on air conditioning equipment, observe precautions in the literature, tags and labels attached to the equipment and all other safety precautions that may apply.

Improper installation, adjustment, alteration, service, maintenance or use, can cause hazardous conditions which may cause serious personal injury and/or property damage.

Consult a qualified installer, service agency, or your sales representative for information or assistance.

The equipment must always be properly supported by rigging and lifting equipment. Any temporary supports used during installation or maintenance must be designed to adequately hold the equipment in place until equipment is permanently fastened and set in its final location. All supports must meet applicable local codes and ordinances.

All fastening devices must be designed to mechanically hold the assembly in place without the ability to loosen or break away due to system operation or vibration.

All pieces are carefully inspected at the factory throughout the entire fabrication and assembly processes under Zehnder

Rittling’s stringent quality assurance program. All major components, subassemblies and paint quality are carefully inspected and verified for full compliance with factory standards.

Each enclosure is carefully packaged in a cardboard container and filled with kraft paper padding for shipment to avoid damage during normal handling in the shipment process. It is the sole responsibility of the customer to provide the protection necessary to prevent vandalism and weather deterioration of the equipment. Under no condition should the finned tube and enclosure be left unprotected from the elements.

If the equipment is not needed immediately at the job site, it should be left in its shipping carton and stored in a clean, dry area of the building or in a warehouse. Do not remove any equipment from its shipping package until it is needed for installation. The equipment is NOT suitable for outdoor installations.

After determining the condition of the cardboard container exterior, carefully remove each unit from the container and inspect for hidden damage. Any hidden damage should be recorded and immediately reported to the carrier and a claim should be filed. In the event a claim for shipping damage is filed, the unit, cardboard container, and all packing must be kept for physical inspection by the freight carrier.

Once the equipment is properly positioned on the job site, cover the enclosure with either a shipping carton, vinyl film, or an equivalent protective covering. Cap open ends of piping that are stored on a job site. Take special care to prevent foreign materials from entering the finned tube in areas where painting, dry walling, or spraying of fireproof material, etc. has not yet been completed as these materials may accumulate on the heat transfer surface. Foreign material that accumulates within the enclosure can limit the heating output of the equipment.

Before installing any of the system components, be sure to examine each pipe, fitting and valve, and remove any dirt or foreign material found in or on these components. Some job conditions may require some form of temporary unit covering during construction.

DO NOT store or install finned tube and enclosures in corrosive environments or in locations subject to temperature or humidity extremes (e.g., attics, garages, rooftops, etc.).

Corrosive conditions and high temperature or humidity can significantly reduce system performance, reliability and overall service life.

30

Handling and installation

While all equipment is designed for durability and fabricated with heavy gauge materials and may present a robust appearance, great care must be taken to assure that no undue force is applied to the enclosure or other delicate components such as finned tube during handling.

Gloves should be worn when handling finished, painted enclosures and should never be set down on unclean, hard surfaces.

Failure to follow these instructions may lead to scratching or gouging of the finished surface.

Anchoring the equipment in place is accomplished by using the mounting points provided, and positioning the unit on a LEVEL plane.

After mounting the finned tube, it is then ready for the water connection.

The proper line size and water temperature should be available to the unit.

On finned tube with steam heating, the proper line sizing and routing should be verified.

The maximum steam pressure should never exceed 15 psig.

The drain piping and steam trap, supplied by others, should be sized and routed to allow for proper condensate flow.

All installations should be made in compliance with all governing codes and ordinances.

Compliance with all codes is the responsibility of the installing contractor.

Hot water connections

Submittals and product literature detailing finned tube operation and connection should be thoroughly reviewed before beginning the connection of the heating medium to the unit.

All finned tube connections are to be made with a sweat or solder joint.

After the connections are completed, the system should be tested for leaks. Since some components are not designed to hold pressure with a gas, hydronic systems should be tested with water. Test pressure must not exceed 250 psig. Pressure testing should be completed prior to sheet rocking, finished floors, painting, caulking, etc.

In the event that leaking is occuring somewhere other than a field installed joint, the Zehnder

Rittling Sales Representative must be notified before any repairs are attempted. All leaks should be repaired before proceeding with the installation.

All finned tube must be protected from freezing after initial filling with water. Even if the system is drained, finned tube may still hold enough water to cause damage when exposed to temperatures below freezing.

Enclosure touch-up and repainting

Enclosure will be furnished with an epoxy powder coated paint finish. Small scratches in the finish may be repaired with touch-up spray paint available from the factory.

Proper safety procedures should be followed regarding ventilation and personal safety equipment when using spray paint. Follow the manufacturer's directions for the products being used.

To repaint the factory powder coat finish, prepare the surface by lightly sanding with #280 grit sand paper or

#000 or #0000 fine steel wool. The surface may also be wiped with a liquid surface etch cleaning product.

These items should be available at most paint product stores. It should be noted that the more care taken during the process, the more effective it will be.

After this preparation is finished, the factory finish should provide excellent adhesion for a variety of air dried top coats. Enamel will give a more durable, higher gloss finish, while latex will not adhere as well and will give a dull, softer finish.

Top coats involving an exothermic chemical process between two components such as epoxies and urethanes should be avoided.

All standard colors including primer can be painted over. If the installing contractor chooses not to paint over the primer color, the factory cannot match primer color on future orders, potentially causing color match issues in the field.

Factory touch-up spray paint may require a number of light coats to isolate the factory finish from the quick drying touch-up paint.

Start-up general

Before beginning any start-up, the start-up personnel should take the time to familiarize themselves with the finned tube and enclosure to fully understand how it should operate properly under normal conditions. All personnel should have a good working knowledge of general start-up procedures.

The building must be completely finished before attempting to start-up equipment, including doors, windows and insulation. All internal doors and walls should be in place. In some cases, the internal decorations and furniture may influence overall system performance. The entire building should be as complete as possible before beginning any system balancing.

The initial step is to visually inspect all of the equipment and piping. Ensure that all systems are properly installed and supported and that all construction debris or foreign objects have been removed from the equipment.

Heating system

Prior to the water system start-up and balancing, the hot water system should be thoroughly flushed to clean out dirt and debris which may have accumulated in the piping during construction.

Strainers should be installed in the piping mains to prevent any foreign material from entering the finned tube during normal operation.

During system filling, air venting from the unit is accomplished by the use of a manual air vent, provided by others.

The air vents provided are not intended to replace the main system air vents and may not release air trapped in other parts of the system. Inspect the entire system for potential air traps and independently vent those areas as required. In addition, some systems may require repeated venting over time to fully eliminate air in the system.

Water system balancing

A complete knowledge of the hydronic system, including its components and controls, is essential to proper water system balancing and should only be completed by a qualified expert.

The system must be complete, and all components must be in operating condition before beginning the water system balancing procedures.

Each hydronic system has different operating conditions depending on the devices and controls installed for the particular application. The actual balancing technique may vary from one system to another.

After the proper system operation is established, the appropriate operating conditions such as water temperatures, flow rates and pressure drops should be recorded for future reference.

Before and during water system balancing, conditions may exist due to incorrect system pressures which may result in noticeable water noise or undesired valve operation. After the entire system is balanced, these conditions will not exist on properly designed systems. If any of these conditions persist, recheck the system for air that may not have been properly vented during start-up.

Water treatment

Proper water treatment is a specialized industry and therefore it is recommended to consult an expert in this field to analyze the water for compliance with the water quality parameters listed below and to specify the appropriate water treatment program. The expert may recommend rust inhibitors, scaling preventative, antimicrobial growth agents or algae preventatives. Anti-freeze solutions, glycols, may also be used to lower the freezing point.

All Zehnder Rittling finned tube is constructed of copper or steel tubes.

It is the end user’s responsibility to ensure that any of the water delivery components are compatible with the treated water.

Finned tube maintenance

Regular maintenance of the fin-tube radiation units will help keep the unit running at optimum capacity. A regularly scheduled inspection and maintenance program should be implemented and followed.

Cover

Use a soft non-abrasive cloth with a standard household cleaner. Under no circumstances should an abrasive cleaner be used.

Heating Element

The heating element should be cleaned at least once every year.

More frequent cleanings should occur if the heating element appears to have a build-up of contaminants. Remove any dirt by brushing or vacuuming the heating element. High-pressure air may be blown through the heating element to dislodge any built-up contaminants.

For a deeper cleaning, spray the finned surface with a neutral cleaning solution and rinse thoroughly.

Zehnder Rittling recommends using neutral pH cleaners. Avoid the use of strong acids and strong base cleaners. Thus, cleaners with pH range from 5 to 11 are suitable for coil cleaning. This range includes such over-the-counter cleaners as

Simple Green

®

All Purpose Cleaner, or HVAC coil cleaners like Nu-

Calgon Evap Pow'r

®.

Strong acidic cleaners (pH of 5 or less) that contain hydrochloric, sulfuric, nitric or acetic acid are not recommended for use on copper-tube, aluminum fin elements.

Presence of these acids will result in rapid corrosion of the metals.

Strong alkali (base) cleaners (pH of 11 or more) containing sodium, potassium or ammonium hydroxide are not recommended as they will aggressively corrode aluminum tubes and fins. Strong ammonium hydroxide cleaners will also cause stress corrosion cracking of copper tubes. Zehnder

Rittling recommends completely rinsing all cleaners from the coil, including cleaners identified as no-rinse cleaners. Residual cleaners may decompose over time producing low molecular weight, organic acids that lead to formicary corrosion.

Replacement parts

Factory replacement parts should be used wherever possible to maintain unit performance and its normal operating characteristics.

Replacement parts may be purchased through the local Zehnder Rittling Sales

Representative.

Contact the local Sales

Representative or factory before attempting any unit modifications.

Any modifications not authorized by the factory could result in personnel injury, damage to the equipment and will void the manufacturer’s warranty.

When ordering parts, the following information should be supplied to ensure proper part identification:

Complete unit model number

Complete part description including any identifying numbers on the part

On warranty replacements, it is often necessary to return the faulty component to receive credit. Contact the local Sales

Representative who will get authorization from the factory including an RGA (Returned

Goods Authorization) to be used when sending components back for inspection. Any returned components sent back to the factory without the proper

RGA attached will cancel any outstanding credit.
