! General Safety Precautions Be sure to read and understand the entire Installation & operation manual before attempting to install or to operate this water heater. Pay particular attention to the following General Safety Precautions. Failure to follow these warnings could cause property damage, bodily injury or death.
Section 3: INSTALLATION The manufacturer’s warranty does not cover any damage or defect caused by installation, or attachment, or use of any special attachment other than those authorized by the manufacturer into, onto, or in conjunction with the water heater. The use of such unauthorized devices may shorten the life of the boiler and may endanger life and property. The manufacturer disclaims any responsibility for such loss or injury resulting from the use of such unauthorized devices 3.
3.4 PIPING INSTALLATION The inlet and outlet piping of the boiler must be in conformity with the different configurations shown below. Make sure that the fluid flows is in the proper direction. Figure 3 : Mounting positions 3.4.1 Type of installation You will find below on figures 4 to 8 the typical piping arrangement for the two main types of installation. The first being as a self-operating unit and the others being connected to an auxiliary boiler in dualenergy.

3.4.2 Boiler piping connection Make sure you connect the accessories and the piping to the proper connection fittings as indicated at figure 2 above and according to the selected mounting position. The outlet and inlet boiler connections are located on each sides. They consist of 4 steel couplings (1”NPTF on 12 to 24kW models and 1-1/4”NPTF on 27 to 36kW) where the piping connection will be made. Local codes may dictate the type of pipe to be used for the connections.
3.4.10 Dual Energy piping Piping connections between the two boilers can be made in parallel or in series as illustrated in fig. 7&8. When installed in parallel, a three way motorized valve (1”NPTF) is used to guide the heating system return water toward the auxiliary boiler or the BTH ULTRA electric boiler according to the operating mode in demand. This way, the oil or gas boiler is not maintained hot by the return water when the operation is in Electricity. N.B.
Both circuits will need to be protected with appropriate breakers or fuse (see table below giving the amperage drawn by the boiler on each breaker) in conformity with local electrical codes. Connections are made directly on the two breakers inside the boiler. These breakers can receive copper or aluminum cable up to #1AWG..
Zoning applications with motorized valves Connect the end switch contact of all motorized valve to terminals R & W on the boiler. Connect the circulator to terminals “P” and “P”- in the boiler. The connection of the thermostats to their corresponding zone valve shall be done according to the zone valve manufacturer’s instructions. See on fig.5 below a typical example. The R & C terminals on the boiler can be used to supply 24Vac to the zone valves if the corresponding load does not exceed 15VA.

Section 4: ADJUSTMENT OF THE CONTROLLER 4.1 INTRODUCTION 4.
4.3 OPERATION OF THE INTERFACE The controller uses four push buttons at the bottom of the display to select and adjust the parameters. The button is used to access the configuration menu and confirm a selection. The buttons are used to select an item or adjust a value. The button enables the illumination of the display under two different modes. The default mode will enable the illumination of the display for a period of 10 sec. each time a button is pressed.
The following tables show the values of the target temperature that will be obtained in relation to the outdoor temperature.

This being done, the installer will have to access the configuration menu by pressing the button for 2 sec. until the first menu appears. The selection of the item or value is made by pressing the button and by pressing the button to get to the next menu. See table 1 below to visualize the menu list that will gradually be displayed. If the buttons remain untouched for a period of 10 sec., the controller will register the value of the selection made and return to the regular display position.
Select the outdoor temperature at which no heating of the building is required (the outdoor sensor has to be installed) 0°F à 105°F 75°F Note 1: Once the operating parameters have been set, the controller will automatically come back to normal display screen. If the user needs to increase or decrease the target temperature, he can do it without having to enter in the configuration menu (see the following section). the selected item and will return to normal operation after 5 sec.
the + button or by re-setting the operating parameters using the tool menus . The Boost menu can be cancelled by selecting “OFF” in the Boost menu. 4.11 OPERATION IN DUAL-ENERGY: In Dual-energy mode, the display will indicate that this mode is active in showing the icon If it is not shown, check the position of the switch located at the back of the controller. It must be set to “Bi-Energ” position. N.B. The controller will have to be reset to register the new mode of operation.
Section 5: START UP OPERATION SAFETY PRECAUTIONS ! Before operating this boiler, be sure to read and follow these instructions, as well as the warnings printed in this manual. Failure to do so can result in unsafe operation of the boiler resulting in property damage, bodily injury, or death.
