Before You Begin

INSPECT FOR DAMAGE

NOTE: Inspect for concealed shipping damage. Damage claims MUST be reported within 10 days of receipt.

NO EXCEPTIONS. Call 1-800-698-9690.

INSPECT FOR COMPLETENESS

Unpack the T6 carefully to avoid damage or loss of parts.

The T6 radiator includes:

Wall Brackets (2) for 16” through 63” width radiators, (3) for 70” and 78” width radiators

(2) Adapters for ½” copper compression (standard) or ½” PEX (optional)

The following are factory installed:

(2) Solid Plugs

(1) Air Vent

(1) Valve insert (Thermostatic Control optional)

APPLICATION

Myson T6 radiators must only be used in a pumped, closed loop hydronic heating system. DO NOT

INSTALL ON A STEAM OR GRAVITY HOT WATER SYSTEM. T6 radiators are designed and constructed for a maximum working pressure of 145 PSI and no more than 230 degrees F water temperature.

Please consult national and local codes for specific restrictions that may be imposed on your installation.

Position radiators away from the circulating pump to avoid either excess pressure that could force water out the air vent or suction which cold draw air into the system. The preferred positioning for the T6 radiator is below a window where it can minimize downdrafts from glazed areas.

Panel radiators may be hot to the touch. Generally, the surface temperature is 10 to 12 degrees Fahrenheit below the system water temperature. Care must be taken to consider the room occupant’s ability to sense or understand that radiators may be hot. Should radiator surface or system water temperature be an issue, please contact Myson at 1-800-698-9690 for information on the Myson LST radiators. LST (Low Surface

Temperature) Radiators can be a viable solution where temperature is a safety concern.

CONNECTIONS

There are two very different connection options for the T6 radiators, and the instructions are separated in the booklet.

Bottom Center Connections: These connections must be used for the internal thermostatic valve to work. The inlet must be the left hand connection as you face the front of the radiator. For series connection (maximum 2

GPM), HV-A or HV-S bypass valves may be used.

Side Tappings: The T6 may be connected like a conventional panel radiator. This arrangement negates the effectiveness of the internal thermostatic valve. It will be necessary to cap the bottom center connections with brass caps. The TRV insert should be removed and replaced with one of the plugs furnished with the radiator.

T6 Radiator Series

Center Connections

PIPING CONSIDERATIONS

T6 radiators are to be connected to one of the following piping systems: Home Run, Two Pipe

Reverse Return, or Monoflo. See page 8 for basic illustrations.

A limited number of T6 radiators may be connected in series using “H” Series By-Pass Valves. The circuit must be limited to 2 GPM Maximum. See page 12.

Installation Using Center Connections

Center connections MUST be used in order for the built-in thermostatic valve to function.

The supply MUST be on the left hand side as you face the front of the radiator.

Each pipe center is one inch (1”) either side of the centerline of the radiator and 2 5/8” from the finished wall.

Remove the two plastic paint caps from the center connections and connect either ½” copper pipe using the compression adapters (p/n 101-68-44) or ½” PEX using the optional PEX adapters (p/n

164-68-50).

The thermostatic valve insert is located in the right hand upper tapping of the radiator, and the air vent is located in the left hand upper tapping. Each may be moved to the opposite side if desired.

Thermostatic room control may be achieved by using the optional Herz TS head available from

Myson, or any Danfoss RA series control (by others).

Thermostatic Valve Inserts are color coded according to factory presets, which correspond to radiator size. Presetting helps with system balance by limiting the maximum flow to the radiator according to BTUH output.

Insert settings are based on 158 degree F. inlet water with a 30 degree temperature drop across the radiator, and may be adjusted for less or more flow.

Installation Using Side Connections

Note:

Center connections MUST be used in order for the internal distribution tubing and the built-in thermostatic valve to function.

The T6 IVC Radiator is designed to be connected using the bottom connections. If necessary the radiator may be installed using the side tappings although a better alternative is to use Myson’s

Select Series Radiators. For more information please contact Myson at 800-698-9690.

Preparing the T6 Radiator for side connections.

• Remove the two plastic caps from the bottom center connections and discard.

• Replace with nickel plated brass caps, PN: T6BCC.

T6BCC

• Remove one of the blanking plugs from one of the lower side tappings.

• Remove the thermostatic valve insert.

• Replace with the blanking plug removed from one of the lower side tappings.

• Remove the air vent assembly, separate and discard the black extension piece.

• Replace the modified air vent in the top tapping. (Air vents should always be positioned on the return side of the radiator.)

• Make sure all tappings are clean and free of debris before proceeding with valve installation shown on page 7.

Optional Side Valve Installation

MYSON

Applies to installation using side tappings.

Myson products are designed to be installed by professional trades people. Myson instructions are meant to be thorough; however it is assumed that the installer has the appropriate technical knowledge related to building codes, standard trade practices, and proper use of the tools of the trade. Should a homeowner without such knowledge or skill take it upon him/herself to attempt the installation, Myson will not be responsible for any damages, injuries or unsatisfactory performance of the Myson product used.

NOTE: MYSON products have BSP male and female threads. BSP threads are a straight

running thread NOT tapered like NPT. Myson Radiator Valves are designed with BSP threads at radiator side and NPT or compression connections to system piping.

Step 1 Clean all threaded surfaces (both external and internal).

Step 2 Apply teflon tape or pipe dope to the male threads, leaving the first thread exposed.

If using pipe dope, also apply to the female threads of the radiator. Common practice

to seal BSP threads is to use heavy duty teflon tape, such as is used to seal gas pipe

fittings, or anaerobic pipe dope.

Step 3 Using accepted trade practices assemble and wrench tighten fittings until proper alignment is obtained.

Valve body stop

Copper pipe must extend all the way to stop. This is critical.

T6 Radiator Series

Optional Piping Arrangements

General information on the use of Monoflo tees:

• Scoop type is placed on the supply feet horizontally from the main, use two monoflo tees facing each other

The T6 radiator is designed to be connected  using the 2”cc bottom center connections. 

These connections utilize the efficient use of  special internal piping and the included  internal Thermostatic Radiator Valve. The 

“Home Run System” piping with a modulating  circulator is the most efficient installation  method. The bottom center connections also  work well with the “Monoflo (1 Pipe) System”. 

If connected in series (“Series Loop”) an “H”  style by‐pass valve must be used and the circuit  must be limited to 2 gpm.  This method is not  recommended. 

The T6 radiator may also be installed using the  alternate end panel tappings, however this will  render the internal piping and TRV non‐ operational and is not recommended.

Conventional Wall Installation Usi ng Optional EZ-Brackets

)

Step 1 Locate studs in wall where the radiator is to be mounted.

Step 2 Mount the brackets so the radiator is a minimum of 4 inches off the floor.

• Failure to allow 4” minimum clearance below radiator can significantly reduce

• Attach brackets firmly to the studs using appropriate hardware making sure the spring loaded connection on brackets is on top.

• All Select Radiators use 2 brackets except as noted on page 9.

• Use a level to assure bracket is plumb.

Step 3 Position radiator to line up with the supply and return pipes.

Step 4 To install the radiator on the brackets, set the bottom edge of the rear panel on the bottom part of the bracket then gently lift and snap the top clip into the grille of the radiator.

NOTE: For mounting instructions of the T6 radiator using the new style EZ brackets please refer to the instructions included with the brackets.

Many MYSON products are in excess of 70 pounds. Care should be taken to have help to lift

larger radiators into place to avoid lifting injuries.

System Start-Up & Maintenance

Failure to flush system of debris and flux may cause premature radiator failure, which can result in leaks and property damage NOT covered under the Myson

Warranty.

SYSTEM START-UP

Step 1 Fill and vent the system.

Step 2 Run the system for two (2) hours at full temperature with all radiator valves in the

open position.

Step 3 Shut off and drain the system while the water is still hot.

Step 4 Refill the system.

Step 5 Reheat, vent, and balance the system.

Step 6 Once the Radiator is filled with water the system should be left filled.

Step 7 System should be checked for leaks on seasonal start-ups. Leaks must be

repaired as automatic system fill valves allow fresh water/oxygen into

the system attacking radiators internally.

MAINTENANCE & CLEANING

1 Once operating, avoid the introduction of fresh water and oxygen to the system to

prevent corrosion.

2 An occasional wiping with a damp cloth using a non abrasive detergent can protect

the finish of your Myson Panel Radiator.

3 The use of abrasive cleaners will damage the surface of your radiator, and void the manufacturer’s warranty.

ADDITIVES

Treatment of the primary water is not usually required in a properly designed system.

Treatment may be necessary if either:

1 Local waters are known for their content of corrosive material or if high bacterial levels

are present.

2 If there is a possibility that the system may be idle during a prolonged period of freezing temperatures, system should be either drained or protected with antifreeze. If either

corrosion inhibitors or anti-freeze is to be used, it should be added AFTER the system has been flushed in the final stages. Use only anti-freeze suitable for potable water.

Do not put heating system into operation without checking for leaks with the system up to full operating temperature. Leaks can appear in a heated system that were not noticeable with a cold system or air pressure check.
