1 Introduction This manual is intended for the gas, electrical and mechanical installer. This document gives instructions on how to use and maintain the air heater. It is most important to follow the instructions in this document for safe operation of this air heater. It is important to read this document before starting the installation process. Store this document close to the air heater for quick reference. 1.1 Symbols used in this manual DANGER! Indicates a dangerous situation that would lead to death or severe injury. WARNING! Indicates a potentially dangerous situation that could lead...

2 Safety instructions Always follow the safety instructions in this chapter when installing, using or performing maintenance on this air heater: CAUTION! Always close the doors and inspection hatches of the air heater, except when adjusting and checking the appliance. CAUTION! This air heater must be installed and maintained by an authorized, qualified and competent installer, using calibrated equipment. Frequent maintenance and cleaning of the air heater is necessary to ensure safe and proper operation. Failure to do so could lead to damage to the heater or its surroundings and void the...

4 Installation 4.1 Preparation Before installation, please use the data badge to check: • if the heater is in accordance with the order; • if the heater is suitable for the local present provisions (gas type, gas pressure, electrical supply etc.) • Make sure enough space remains to open the door of the air heater. • Make sure the wall can support the air heater. • Ensure sufficient clearance distance for the flue system. Before leaving the factory, the air heater has been tested for safety and has been set to the operating settings. It has been configured for the type of gas that is stated...

NOTICE All gas supply lines must be mounted without any mechanical tension. NOTICE Always clean the inside of a gas supply line before connecting it to the air heater. Place a gas filter in the supply line when needed. • When replacing this fuse, always use one of the same type (5AT). 4.5 Room thermostat The air heater can be controlled in two ways: CAUTION! When using pressures above 60 mbar to test the supply lines, always close the manual isolation valve of the air heater. • by an ON/OFF signal; • through a bus communication system with an external interface. For United Kingdom only: The...

To connect the air heater to a bus communication system, do the following: 1. Connect the two control wires to terminals 4 and 5 (see figure 5 or the electrical wiring diagram in §11). 2. Set the S1 and J14 switches on the control unit as follows (figure 6/7): ||The air heater must be switched off when setting the switches. Otherwise the settings will have no effect. An MTC or MTS room thermostat, or interface module can control up to 8 air heaters. To connect the air heaters, do the following (figure 8): ||This functionality does not apply to an ON/OFF thermostat. 1. Connect the two wires...

Figure 9 - Positions of the S1 and J14 switches for the first three air heaters in a system NOTICE If the J14 switch of more than one air heater is set to the same number, the system will not work. NOTICE The air heater must be switched off when setting the switches. Otherwise the settings will have no effect. ON/OFF thermostat installation To connect the air heater to an ON/OFF room thermostat, do the following: • Connect the two thermostat wires to terminal 6 and 7 (see figure 10 or the electrical wiring diagram in §11). This is a 24 V connection for the thermostat signal. Figure 10 -...

To ensure safe and proper use, this air heater must be connected to a flue system. This flue system must be installed according to this manual as well as national and local regulations. A flue system consists of a flue terminal, piping and an optional condensate discharge system. Do not use flue terminals for condensing appliances on non-condensing heaters. This can lead to water inside the flue system. NOTICE [lOnly use the prescribed flue material for the roof terminal, wall terminal and for the piping between the heater and the terminal. This is the only way the installation will be...

5.1.1 Flue material Only use CE marked flue material from the manufacturers Muelink & Grol (M&G) and Burgerhout. Use type Alu-fix with a minimum temperature class of T200 P1. or M&G's Stainless Steel SP Isoflex 0.10 flue material T200 P1. Use flue pipes with the same diameter as the flue spigots on the heater. 5.3.2 Air heater location When an air heater burns frequently and is placed in a normally heated room (temperature above 15 °C), condensate is unlikely to form. Air heaters placed in a room that needs to be just above 5 degrees will only burn for short periods at the time. Formed...

Figure 14 - Condensate drain 5.4 Installation of the flue terminal NOTICE There are flue terminals available for installation through a roof or through a wall. ||The flue terminal must be installed according to local and national regulations. Do not combine components or materials from different manufacturers. 4. Put the flue terminal into a vertical position. Use a level. 5. OPTIONAL - If desired, fit cover plates. These are supplied separately. 6. Place the supplied wall clamp around the flue terminal and fit it to the roof construction. Do not tighten the clamp yet. 7. Connect the gasket...

Installation - Wall terminal To install the flue terminal in a wall, do the following: 5.4.3.2 Elements system ALU FIX thick wall An ALU FIX flue system is created with four elements (figure 15). 5.4.2.1 Preparation 1. Check all components for possible damage. 2. Determine where the flue terminal will be positioned. 5.4.2.2 Installation 1. Create a hole through the wall. CAUTION! Make sure no debris or dust gets into the air heater. 2. Carefully insert the flue terminal from the outside. CAUTION! Do not rotate the cap. 3. Put the flue terminal in a horizontal position. Use a level. 4. Mark...
