Precautions for installation To use the APP together with the Wi-Fi remote controller a wireless router must be available. If there is no wireless router, it must be installed. If connection between Wi-Fi remote controller and server is lost because of problems caused by the internet connection, router or natural disaster, Rinnai Wi-Fi boiler application may not function properly. Checking wireless routers 1. This product only supports DHCP (Dynamic Host Configuration Protocol). If the user wishes to use an existing wireless router, DHCP server option must be enabled. 2. Channels 1~13 are available for wireless routers. 3. Encryption of wireless router supports WPA and WPA2, but it does not support WEP and non-standard authentication methods. 4. Quality of wireless network connection can be affected by surrounding wireless environment. 5. Some wireless routers can send abnormal DNS address even if they are not connected to the internet, which causes Wi-Fi icon on the LCD window of indoor temperature controller to be turned on. In this case, please contact the manufacturer of corresponding wireless router and internet service provider. 6. Rinnai Wi-Fi boiler only supports wireless routers with Wi-Fi 2.4Ghz. 7. Rinnai Wi-Fi boiler supports IEEE802.11.b communication protocol. Make sure to check whether the router supports IEEE802.11.b before installation. 8. Only use letters and numbers for the name of Wi-Fi connection (characters like &,%,+,é... may not be supported). This device is appropriate for electromagnetic waves at home (class B) and is intended for use at home. It can be used in all regions. 6

Installation
Remote Controller Installation 1. Requirements for an Installation Location. 1) Install a remote controller on the wall at the height of 1.2~1.5m from the floor. Also, the location provides a sufficient clearance for allowing of each access. A living room or a main bed room could be suitable. 2) Improper installation location. Place where the temperature would elevate to 40 or above (Adjacent to a gas boiler and others) Place with direct sunrays Place with a high level of moist (A gas stove, a rice cooker and others) Place with the risk of water spattering Greasy area Place where special chemicals (benzene, oil-based detergent and others) 2. Power Connection of the Remote Controller. Caution Power lines of the remote controller must be a two-wire two-layer vinyl chloride sheath copper wire and the aged power lines should be exchanged. When the sheath is peeled off, it could lead to a short circuit or current leakage, in turn deteriorating the boiler. Do not tie up the power lines of the remote controller with other 230V AC power lines, or place them together in the underground wire piping. Electric noise could arise. When the remote controller is connected, Cover the power lines with the insulating tape to prevent a short circuit or current leakage. When the remote controller malfunctions due to the electromagnetic wave noise, change the power lines of the remote controller to the shield cable, which could shield the noise. 1) Connection of the Remote controller Do not plug the boiler until a power line of the remote controller is connected to the boiler. Do not plug the boiler into the outlet until the installation of the remote controller is completed. Do not disassemble the remote controller. It could cause abnormal operation of the boiler. Power lines of the remote controller should be wired not to be influenced by direct heat. The remote controller does not have the polarity. 51
3. Mounting the Remote Controller. 1) Mounting the Remote Controller to the Wall Make a hole for the hole plug (ø6.0x depth 35~40mm) on the wall and then, insert the hole plug. Drill a hole to be vertical to the wall. Do not exert too much force. Otherwise, it could damage the remote controller. Do not excessively fasten the screw. Otherwise, it could deform the bracket, which would make the installation hard. When the power line of the remote controller is taken out through the bottom of the remote controller, it should be taken out in between the bottom of the bracket and the furrow on the remote controller. 2) Mounting the Remote Controller to the Switch Box After separating the bracket from the remote controller and then, affix the bracket with the flat headed screw, comes with the boiler. Connect the power line of the remote controller and then, put the remote controller into the bracket. Affix the bracket securely to the wall with the flat headed screw. If screws other than the flat headed screw are used, it might not be possible to mount the remote controller.
