Installing your Myson Towel Warmer

Rough-In Details for all Wall Units:

  • Premier (B24, 26, 29, 30, 31, 34) and Classic (S6, S11, S14, CYG14) Towel Warmers rough-in with 3/4" copper.
  • Multirail (MRR) Towel Warmers rough-in with 1/2" copper.
  • All Towel Warmers (except B29 and MRR models): rough-in on the centerline of the bottom rail.
  • B29: rough-in 2" below bottom of unit on centerline of the vertical rails.
  • MRR: rough-in 1-1/2" below bottom of unit on centerline of the vertical rails.

Caution:

1. Please read this entire instruction manual thoroughly before beginning installation.

2. It's a good idea to follow these instructions accurately to make certain the towel warmer is properly attached to the wall or floor. FAILURE TO FOLLOW THESE STEPS COULD RESULT IN PROBLEMS.

3. You should not ever use an abrasive cleaner on these towel warmers. A mild liquid (non scrub) detergent will clean and restore most units to their original beauty

4. To insure full efficiency of your quality Myson towel warmer, please do follow all instructions carefully, and always observing the "CAUTION" notations for each step.

5. Inlet water temperature should be between 120°F and 150°F. DO NOT exceed this limit. A burn hazard may result.


Step 1: Pre-Installation

A. Select Installation Site: Make certain there is ample clearance on both sides and back of the towel warmer.

Note: This unit is supplied with the proper hardware for installation. Be sure wall construction is appropriate for hanging (See Step 3A).

B. Before beginning the installation of any Myson hydronic towel warmer please note the following:

  1. Maximum operating temperature should be no higher than 150°F or 66°C. Any working water temperature higher than 150°F could create a potential burn hazard.
  2. Myson hydronic towel warmers take 20 to 30 minutes to heat towels properly. For this reason, we do not recommend piping towel warmers through shower valves.
  3. Myson hydronic towel warmers can be safely operated continually year-round without turning them off.
  4. Myson hydronic towel warmers may be controlled by a timer or a thermostat that controls the system pump.

C. Refer to rough-in information on back page


Step 2: Inspect Myson Towel Warmer

A. Unpack the Myson towel warmer carefully to avoid any damage or loss of any part. When opening the box and unwrapping the towel warmer, be sure that parts are not accidentally discarded. (See illustration, fig 1).

B. Myson towel warmers are shipped in specially designed shipping cartons. The entire surface of the towel warmer is hand-wrapped to protect the finish. Check the wrapping for any sign of damage. Carefully remove the protective wrapping and move the towel warmer into position.


Step 3: Installation

A. Mounting:

  1. The Myson towel warmer has been designed with integral fixing flanges. These will facilitate a permanent and secure mounting of the towel warmer to the wall or floor using the screws provided. In addition, some models come with adjustable wall stays, for extra security.

B. Valve Installation:

  1. The valves are composed of a main body, a union connection, and a copper compression ring and nut located at the bottom of the valve (Have the sleeve kit available at this time).
  2. The sleeve kit consists of a small escutcheon plate and matching 3" piece of tubing used to cover the water pipe connections.
  3. After having stubbed the copper tubing, place the sleeve and escutcheon plate over exposed copper tubing.
  4. Place compression nut and ring on to the copper tube (see fig 2).
  5. Next, remove the valves from the towel warmer and check to be sure that the valves are completely OPEN.
  6. Important: There are two valves that will need to be purchased separately for the Myson hydronic towel warmers. One valve is always permanently open, but the other valve can be opened or closed. These valves seal only in the fully OPEN or fully CLOSED position. Using the valve to throttle the water flow will result in a leak at the valve stem.

  7. Remove union and nipple from the valve. Apply either PTFE thread sealing tape or pipe joint compound on the threads of the nipple. Hand tighten nipple to towel warmer. With an allen wrench inserted into the nipple, hand tighten to secure appropriate fit.
  8. (DO NOT USE A PIPE WRENCH OR PLIERS, and DO NOT OVERTIGHTEN. OVERTIGHTENING WILL CAUSE THE UNIT TO LEAK)

    Note: One to three threads may still be visible when tightened.

  9. Set valve into position and seat copper tubing into the base of the valve. Seat the union nipple into the valve and loosely tighten the union nut. Hand tighten the compression nut.
  10. Caution: DO NOT TURN THE VALVE BODY, TURN THE NUT ONLY. Turning the valve body will split the compression ring, making a good seal unlikely. DO NOT OVERTIGHTEN!

  11. Turn the compression nut 1/4 turn more to securely seal. Tighten union connection to valve. Repeat for second valve. Water is ready to be circulated through your Myson towel warmer at this time.
  12. Connect towel warmer to hot water system using one of the options shown below. When all connections are complete, add water and vent unit using the bleed valve located on the top rail at the back or side of the unit, depending on the style of the unit.

Note: The key for the bleed valve is provided with the unit.


Step 4: Operation & Maintenance

Your Myson towel warmer can be left on continuously without detrimental effect either to the towel warmer or to the articles on it.

Cleaning:

The finish of your Myson towel warmer can be protected and maintained by an occasional wiping with a damp cloth and lightly polished thereafter with a soft dry cloth. Under no circumstances should abrasive cleaning powders or metal polish be used on any part of a chrome or gold plated towel warmer.

Two Gallon Electric Water Heater Connection

General: Myson towel warmers require a hot water supply at a temperature between 120°F and 150°F. This connection scheme uses a stand alone hot water heater as the heat source. A small two gallon heater is all that is required.

  1. Connect the towel warmer to the heater as shown in figure 4. The circulator pump should be installed on the hot water discharge of the mini heater. The return is connected to a return port on the mini heater or it may be joined with the cold water supply. A shutoff valve should be installed on the cold water supply. Install a pressure relief valve on the mini heater.
  2. Use a 3-way mixing valve to reduce the water temperature going to the towel warmer to not exceed 150°F.
  3. Fill and vent the towel warmer. Open the towel warmer air vent using the vent key provided. Close the air vant and allow the water to circulate. Venting may be required several times after heating in order to remove all of the entrained air.
  4. Control circulator pump using a thermostat, timer, or manual switch.

Steam Boiler (using condensate) Connection

  1. Install a 3/4" bypass loop with full port ball valve from the condensate return to the hot water draw off. DO NOT connect to a steam line. Myson towel warmers require water at a temperature not to exceed 150°F.
  2. Connect towel warmer on a separate zone with the circulator pump on the feed line to the towel warmer as shown in figure 5.
  3. Install a 3-way mixing valve connecting the towel warmer return and the feed from the boiler as shown.
  4. Fill and vent the towel warmer. Open the towel warmer air vent using the vent key provided. Close the air vent and allow the water to circulate. Venting may be required several times after heating in order to remove all of the entrained air.
  5. Adjust full port ball valve on the boiler bypass line to divert a portion of the return through the boiler to add heat to the zone.
  6. Balance system to attain a 150°F water temperature going to the towel warmer

Domestic Hot Water Heater Connection

  1. Myson towel warmers are brazed with drinking water safe materials, and are compatible with domestic hot water systems, See figure 6. Hot water temperature must be set to a maximum of 150°F.
  2. Install a circulator pump on the feed line to the towel warmer. Connect towel warmer return with the cold water supply to the hot water heater. Provide a check valve on the cold supply as required by local codes.
  3. Fill and vent the towel warmer. Open the towel warmer air vent using the vent key provided. Close the air vent and allow the water to circulate. Venting may be required several times after heating in order to remove all of the entrained air.
  4. Control circulator pump using a thermostat, timer or a manual switch.

Radiant Heat Systems Connection

  1. For radiant heat systems which have available water temperatures greater than 150°F, follow the instructions for connection to hydronic (hot water) heating systems in figure 4.
  2. For radiant heat systems operating at about 120°F, follow the instructions for connection to domestic hot water heaters in figure 6.
  3. For low temperatures radiant heat systems operating at less than 120°F, a separate heater is required. Follow the instructions for installation using an electric water heater in figure 4.
