ShowerWarm™ elements have been specifically designed for safe installation in showers.
The patented element is double insulated, waterproof and absolutely safe provided the following specific installation instructions be observed:
- Install the shower floor liner in accordance with the manufacturer’s instructions.
- Apply a coat of mortar over it with a slight slope from the edges down to the drain.
- Ensure that the drain barrel is set at the correct height above the mortar to accommodate the thickness of the tile and thinset to be used.
- Allow an additional 3/16th inch for the combined thickness of the Speedheat® ShowerWarm™ heating element, ProtectaMesh, and thinset skim.
- Note: It will be extremely difficult to reset the drain barrel height after the heating has been installed, so it is important to get it right first time.
- 3. DO NOT install the heater until the mortar is completely dry and cured.
- 4. If Heating Shower Seats or Benches…
- They MUST be built-in before heater installation.
- 5. If Installing a Waterproof Liner on the Seat…
- a. The liner MUST be covered with mortar in the same manner as the shower floor.
- b. The mortar MUST be dry and cured before heater installation.
SHOWERWARM™ HEATER INSTALLATION
- The Connector Blocks MUST be installed OUTSIDE the shower enclosure.
- a. These are factory-installed “Connector blocks” that connect the heating element to the electrical supply hookup leads.
NEVER INSTALL THE CONNECTOR BLOCKS INSIDE THE SHOWER.
- Run the Out Hot Tail element wire from the Connector Block…
- 1st. Along the bathroom floor
- 2nd. Up and over the shower threshold
- 3rd. Attach the hot tail to the threshold with duct tape.
- Shower Doorframe Attachments
- Make sure that, when installed at a later stage, the shower doorframe attachments do not cut the element wire where it crosses over the shower threshold.
- Secure the heating element to the shower mortar bed with the factory fitted adhesive tape attached to the element strip.
- DO NOT use staples to secure the element to the shower floor, as these may puncture the shower floor liner.
- Usually, the “freehand” method of element wire installation will have to be used on a shower floor.
- Maintain the correct spacing between freehand runs of element wires.
- Leave an unheated 6-inch gap all the way around the drain.
- Shower Seats and Benches
- When a shower seat is to be heated as well as the shower floor, continue an ‘extended hot tail” from the floor up the wall of the seat to the top of the seat, attaching the element to the seat wall with duct tape.
- Leave an unheated gap of 2 inches around the edges of the seat, cover the rest of the seat with heating element, maintaining the correct spacing between element wire runs.
- After covering the seat with heating element, use duct tape to attach another “extended hot tail” down the seat wall, then along the floor of the shower and up and over the shower threshold back to the bathroom floor.
- Cover the heating element in the shower, on the seat and on the bathroom floor with self-adhesive ProtectaMesh.
- Apply a thinset skim over the ProtectaMesh for added protection during tile setting.
- Attach the continuity monitor to the heater as instructed.
- Extreme care must be exercised by the Tile Setter at all times, but especially so when setting tile in the shower area.
- Any damage to the heating element in the shower area will require replacement of the entire heating element as field splices are not permitted inside the shower.
- Only a GFCI protected thermostat must be attached to the heater and should be located on an interior wall in a safe position, which complies with the National Electrical Code and any local regulations.
