Installation Instructions

WHAT IS IN THE BOX

• 500 Watt Envi Wall Mounted Heater
• Owners Manual
• 2 x Mounting Clips
• 2 x Drywall Anchors / 2 x Masonry Anchors
• 2 x #8 Mounting Screws
• Locking Bar Screw and 3/32″ Hex Allen Key tool

Economical Safe Simple

WALL MOUNTING

1. Unwrap and flatten the sides of the packaging insert frame (mounting template) and stand the template on the floor. The sides of the template have pre-punched holes to mark the heater mounting height for either 6” or 8” (15 or 20cm)from the bottom of the heater to the floor. Choose either mounting height, and mark two hole locations on the wall. (see Fig. 1).
2. Screw the anchors (Fig. 2) into the wall at the marked locations. The distance from the top screws to the floor should be approx. 19″ to 21″ (48cm to 53cm). If a stud is in the way, do not use the drywall anchor supplied, just drive supplied mounting screw directly into the stud. For masonry walls, use the masonry wall anchors provided and drill a 4.5mm (3/16inch) hole using a masonry drill bit (not supplied) Important Mounting Tips  The right-hand side of the heater must be securely and firmly pushed down on the clip to engage the “wall-sens” power cut-off switch inside the heater.  Align this side of the heater first, to ensure the switch is activated. For uneven walls, a thin washer can be used to widen the gap behind this clip to help seat the heater properly. The heater can be mounted at other heights besides 6″ or 8″. To do this, measure where you want the bottom of the heater to be on the wall and then measure up an additional 13″ (33cm) and mark your screw locations.
3. Screw the two mounting clips (with an arrow pointing upward) into the top two anchor locations and secure them firmly to the wall anchors using the providedscrews. (see Fig. 3). DO NOT overtighten. There should be a gap behind the mounting clip to hang the heater on.
4. Note: make sure you pre-install the Locking bar screw before you mount the heater. (See Fig. 5 below). Install the heater on mounting clips (align the right side first) and make sure to press down firmly on the heater to ensure a secure fit. You will hear it “snap” into place. (Fig. 4 above)

Installing Locking Bar for Permanent Attachment

Envi Wall-Mounted Heaters have an additional method to permanently attach the heater to the wall. A locking bar mechanism is built inside the heater, which is engaged by screwing an external locking screw into the bottom of the heater vent. The locking screw and Hex/Allen Key are both provided in the mounting kit. This locking bar method is an alternate method to the existing bottom screw installation procedure above, however many customers will find that the locking bar attachment method is sufficient by itself.

1. Installing the Locking Bar Screw  BEFORE YOU MOUNT THE HEATER TO THE WALL. Take the locking bar screw out of the mounting kit and while the heater is lying flat, use the Hex/Allen key provided to pre-install the screw in the hole at the left-hand side of the bottom vent (Fig 5). Twist the locking screw in about 3/8 of an inch but make sure you do not screw it in too far as it will obstruct the mounting holes at the back of the  heater and prevent secure mounting.
2. Mount the Heater. Attach the heater to the wall by following the mounting instructions on the previous page.
3. Tighten Locking Screw (Fig 5) Follow the rest of the mounting instructions to ensure the heater is properly seated on the mounting clips and then tighten the locking screw to fix the heater to the wall. DO NOT USE A POWER TOOL! DO NOT OVERTIGHTEN, just turn the screw until the locking bar presses gently up against the left-hand mounting clip inside the heater.

Hardwiring Instructions

The Envi Heater is available in some regions as a hardwired model LE5012D/LE5022D (with built-in thermostat) and LE5012N/LE5022N (with no built-in thermostat, instead a cover plate is in its place). The Envi Heater can be hardwired directly to a mains supply, or branch circuit or it can be hardwired to a line voltage external thermostat of the same voltage as the heater (eg. 120v) or to an external switch or timer. Consult the instructions for each of these control devices for specific wiring instructions.

The Envi Heater can also be wired as multiple heaters on the same circuit or controller. The Envi Heater can also be hardwired to a low voltage thermostat, for these and Multi-Heater Hardwiring instructions please visit the installation page of the website www.eheat.com. Please consult a certified electrician and ensure that all electrical work is done according to applicable electrical and building codes.

CAUTION

To prevent short circuits and electrical shocks turn the power off at the main electrical panel before attempting the hardwiring installation or any repairs. If the internal power cable (cordset) is damaged it must be replaced by the manufacturer.

NOTE

This hardwired heater must be connected to the correct voltage circuit according to its model designation, ie. (LE5012 = 120 volts, LE5022 = 220 volts). Disconnect the power supply before making wiring connections to prevent electrical shock and equipment damage.

WIRING SCHEMATIC

NOTE: The following wiring schematic is for a single Envi Heater installation to the applicable AC mains supply circuit and assumes that no external controls are being to the heater. For wiring of external controls(thermostat/switches or timers) please consult the website  www.eheat.com for examples of external control wiring instructions.

1. Determine the best wall mounting location of the Envi Heater in a room. If the proper electrical wiring and wall box already exist at a suitable height on the wall, then choose a suitable knock-out hole on the back of the heater (5 holes to choose from) and position the heater on the wall so that the knockout hole lines up with the electrical wall box. Refer to Fig. 8 for more details. If new heater circuit wiring and wall box are to be installed, then it is best to mount the heater first and then determine the corresponding location on the wall for the new electrical wiring wall box. When installing a new wall box, ensure it is at a proper location on the wall to allow the heater to remain 6” to 8” (15cm to 20 cm) or so above the finished floor level. Turn the power OFF at the main electrical panel to the heater circuit. Run the electrical wiring and secure it properly to the electrical box per applicable electrical and building codes.
   NOTE: Although the Envi Heater has a low amperage draw (eg. 4amps@120v), the electrical code requires a minimum supply wire gauge to be used usually 12g, so make sure you check first.)
2. Mount the Envi Heater using the two mounting clips per the “Wall Mounting Instructions” (see page 4)contained herein to ensure that the heater is at the proper location on the wall and that the knockout hole is aligned with the supply wiring.
3. Remove the Envi Heater from the wall to prep for the hardwiring steps. Pull the cords through the knockout hole using pliers and install the supplied protection grommet. Strip wires to expose 5/8″ of copper on all 3 of the cord set wires (see Fig. 8)
   Install the bottom door supplied in the mounting kit. Rotate and lay the heater on the ground so that the bottom right corner is facing up and the back of the heater is facing the wall (see Fig. 9).
4. Push as much of the connected wiring/nuts deep inside the wall box opening and the heater will sit flush with no wiring trapped between the heater and the wall. Carefully lift the heater back onto the wall mounting clips that were installed earlier. Re-mount the Envi Heater to the wall, ensuring all three mounting screws are used and the   Locking screw is tightened.
5. Turn the power ON at the main electrical panel to the heater circuit. Check that there are no obvious problems with the hardwiring to the heater (such as crackling noises, sparks, or smoke) and if everything is okay, turn on the power to the heater by pressing the on/off button. If the wiring has been performed correctly, then the power indicator light will glow red.

220V (4 WIRE) BASIC HARDWIRING GUIDE FOR USA MODELS LE5022D & LE5022N

Please note that this is a very basic and “rough guide” and may not apply to every situation. The terms “110 volts” and “220 volts” are synonymous with 120 volts and 240 volts respectively. When a customer encounters existing 220-volt, four-wire, supply wiring, there could be more than one way these wires might be configured, however, the usual 220-volt arrangement is as follows. Typically 220 volt, 4 Wire supply wiring has a Black Wire and a Red wire, each of which is 110-volt live legs. Sometimes these are two Black wires. There will sometimes be a White Wire which is usually a neutral wire used to power a 110-volt device(do not assume this though, because it could be a thermostat leg or another ground wire). Lastly, there should be a Green or bare copper wire is usually the ground wire. Did you catch how many times we use the words “usually” and “sometimes”? Be very careful and never assume!

Did you know? 220 volt supply (now known as 240 volts in the USA) comes into a home from an outside transformer on two separate wires (legs) which have opposite phases or polarity. The electrical current alternates on one leg from +110 volts to 0 volts and alternates from -110 volts to 0 volts on the other leg (wire). The overall difference between the two legs when connected is 220 volts. So, now you know where 220/240 volts comes from!

Operating Instructions

HOW IT WORKS

The Envi Heater is designed with innovative “Stack Convection Technology” that effectively heats a room with minimal energy. The Envi’s inner chamber simulates “stacks” of varying heights, which boost airflow through the heater to achieve maximum efficiency. The result is enhanced airflow at safe air temperatures, all without the use of a fan. The Envi heater will provide consistent, comfortable, silent heat without drying out the air or leaving cold spots in the room.

WALL-SENSTM SAFETY FEATURE

n addition to the overheat safety cut-off, the Envi Heater is equipped with an additional layer of safety to give you greater peace of mind. Wall-SensTM technology means that if the Envi heater is ever removed from the wall, power will be immediately cut to the heater. This of course means that the heater will not work if it is simply removed from its packaging and plugged into a wall outlet. It must be mounted properly (safely) and then plugged in (or hardwired) for it to begin to heat.

ELECTRICAL GROUNDING

Plug-in models of the Envi Heater are for use on standard electrical circuits (eg. 120v for USA/Canada). The cord has a three-blade grounding plug. An adapter can be obtained at most hardware or electrical stores for connecting three-blade grounding-type plugs to two-slot receptacles. The grounding lug extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box. The adapter should not be used if a  three-slot grounded receptacle is available.

OVERHEAT SAFETY FEATURE

This heater is equipped with an overheat safety feature. When the heater’s internal components reach a certain temperature that could cause overheating and a possible fire, the heater will automatically shut off. To reset the heater, unplug the power cord from the electrical outlet for 10 minutes. After 10 minutes, plug the heater into the electrical outlet and turn it on using the heater’s on/off switch located on the front of the unit.

OPERATING INSTRUCTIONS

1. Install the heater on a firm, level wall and plug the power cord into a grounded power outlet (or hardwire if applicable). The heater will only operate when it is properly attached to the mounting clips. Be sure to mount it in an upright position with the thermostat dial and power button at the top of the heater.
2. Once the heater is connected, press the front on/off power button and the POWER INDICATION LIGHT will glow red. (Fig. 10)
3. The Envi Heater is equipped with a built-in thermostat which is adjusted with a dial at the top of the heater. Adjust the room temperature by turning the thermostat dial CLOCKWISE to increase the room temperature. If the area becomes too warm, rotate the thermostat dial COUNTER-CLOCKWISE until the temperature is more comfortable.
4. Once you have chosen the desired setting, the thermostat will maintain a constant temperature.
   NOTE: Models with no thermostat have no temperature control and will stay on until the heater is powered off by either an external switch or an external thermostat.
   NOTE: For models hardwired to an external thermostat, the built-in heater thermostat should be left on the hottest setting.
5. The heater is equipped with an innovative auto-dimming feature that dims the power light in a darkened room to help light sleepers. The heater automatically detects when the light level in a room drops and then dims the power light.
6. The plug-in cord set of the Envi heater can be stored inside the bottom access door. Determine how much or set you require to extend out of the heater. Remove the heater from the wall, and remove the bottom access door. Carefully push the excess cords Care & Maintenance Instructions page 9 inside the heater (use a wooden ruler or similar) and replace the bottom access door. Re-install the heater to the wall and plug in the cord set to continue using your heater. For more information please visit the installation web page of www.eheat.com

OPTIMAL OPERATING CONDITIONS

To get the most out of your Envi Heater, please follow these helpful hints:

1. VERY IMPORTANT!!! For optimal performance in a room, close all windows and doors and for first-time use, leave on for 48 – 72 hrs. This will allow the room to reach an equilibrium temperature while the heat is gradually building up.
2. For optimal performance, mount the heater on an interior wall with the bottom of the heater 6” to 8” (15 to 20cm)from the floor. For smaller rooms this can be increased with little detriment, however, try to keep the bottom of the heater a maximum of 18” (46cm) from the floor.
3. The 500-watt Envi heater is designed to heat rooms 130 to 150 ft2 feet in size (12 m2 to 14 m2). This equates to a 10ft x 14ft room size (3 x 4 meters). Of course, this will vary depending on several factors, including outdoor temperature, room insulation, room draftiness, room objects, etc.
4. To save energy and reduce your heating bills, place the heater in a room or area that needs extra heat instead of raising the thermostat on your central heating system. This heater will function very well as both a sole source of heat and as an additional heating source that can easily maintain the temperature in most rooms and attached bathrooms if the correct number of Envi heaters is installed. There is no need to increase the heat in the entire house when you only need comfort in the room in which you are currently located.
5. We highly recommend that our customers weatherize their homes or offices to further reduce their heating bills. Simple tasks such as replacing weather stripping around doors and windows, caulking doors and window seams, sealing attics and basements properly, and adding more insulation to your walls and ceiling will help further reduce heating costs.

Care & Maintenance Instructions

CLEANING

1. Unplug the unit and let it cool completely.
2. To remove dust from the Envi heater, use a soft cloth on the exterior, and compressed air can blow dust through the top vent of the heater out the bottom.
3. To remove marks or stains from the heater, the front outer shell can be cleaned with a soft, damp cloth. You may use a mild detergent if necessary. After cleaning, dry the unit with a soft cloth.
   CAUTION: Do not let liquid enter the heater.
4. Do not use alcohol, acetone-based cleaners, gasoline, abrasive powders, furniture polish, or abrasive or rough cloths or brushes to clean the front of the heater. This may cause damage or deterioration to the surface.
5. Do not immerse the heater in water.
6. Wait until the unit is completely dry before using it again.
7.  Some customers, over a long period, may experience “dirty marks” on the wall above the heater. This is caused by smoke from tobacco products or candles being drawn into the heater and passed out the top. Over time this may leave dirty marks above the heater. The wall is not damaged and can easily be washed using appropriate cleaning products such as a magic eraser sponge.

STORAGE

Store the heater in a cool, dry location when not in use. However, the Envi Heater is a slim, attractive wall-mounted heater that can be left mounted on the wall – all year round!

Trouble Shooting

If the heater will not operate, please check the following before calling for help with technical questions:

1. The number one troubleshooting tip is to check that the internal, electrical safety switch (Wall-SensTM) is being engaged. The heater WILL NOT OPERATE AT ALL if this switch is not engaged. This problem occurs when the right-hand side of the heater is not pushed down far enough between the gap between the wall and the mounting clip. The mounting clip can become squished if it is screwed in too hard. Uneven walls can also cause the same mounting/wall switch problems.
2. Check if the power cord is plugged into an electrical outlet and the heater is set to ON by confirming the light on the front of the panel is lit. If not, plug in the heater and press the on/off power switch.
3. If the heater has been hardwired, consult an electrician to check that all connections have been made correctly. Make sure that you hardwire the correct voltage. Many people do not understand how to work with 220-volt wiring. Always triple-check the voltage and the model heater that was purchased as this is a common mistake and can lead to heater malfunction and pose a serious safety risk.
4. Check if there is electricity in the circuit by checking to make sure the breaker in the breaker box is in the “on” position.
