Page 5: Heater Location
2.5 HEATER LOCATION Attention Flue requirements may affect location. Consult section 7 before making a final determination. Use the minimum clearances as illustrated in figure 2 and the throw data mentioned in table 1 (Technical Data) to define where to locate the heater. Also respect the recommended minimum height as given in table 1. For best results, the heater should be placed with certain rules in mind. Always ensure that minimum clearances are maintained. Locating a unit heater above the maximum recommended height can result in significant air stratification. When possible, heaters should be arranged to blow toward or along exposed wall surfaces. Suspended heaters are most effective when located as close to the working zone as possible, but care should be exercised to avoid directing the discharged air directly on to the room occupants. Partitions, columns, counters or other obstructions should be taken into consideration when locating the unit heater so that a minimum quantity of airflow will be deflected by such obstacles. When units are located in the centre of the space to be heated, the air should be discharged toward the exposed walls. In large areas, units should be located to discharge air along exposed walls with extra units provided to discharge air towards the centre of the area. For optimum results heaters are best used in conjunction with recirculating air fans suspended at high level. At those points where infiltration of cold air is excessive, such as entrance doors ... it is desirable to locate the unit so that it will discharge directly towards the source of cold air, typically from a distance of 4.5m to 6m or install a downflown unit over the door opening. If touched, the vent pipe and Do not locate the internal heater surfaces that are heater where it may accessible from outside the heater ... -

7 AIR SUPPLY & FLUE SYSTEM 7.1 GENERAL The flue must be in accordance with all international and national rules and regulations in force. Local requirements may apply in addition to national requirements. WARNING Failure to provide proper flueing could result in death, serious injury and/or property damage. The products of combustion must be flued to outside atmosphere. Common flues (for more than one appliance) must not be used. Single wall flue pipe exposed to cold air or run through unheated areas should be insulated to avoid condensation. If the flue passes through a combustible element of the building it must be enclosed by a sleeve of non‐combustible material and separated from the sleeve by at least a 25mm air break. The temperature of any combustible material near to the flue must not exceed 65°C when the heater is in operation. The flue must be at least 50mm away from any combustible material. Provision must be made for condensation to flow freely to a point to which it can be released, i.e. drain. Model ULSA/ULSA EC heaters may be installed as type B or type C installations. The unit heaters are designed to operate safely and efficiently with either a horizontal or vertical flue system when installed according to the specific requirements and instructions. If this heater is replacing an existing heater, be sure that the flue is of the correct size and that the existing flue is in good condition. A correctly sized flue system is required for safe operation of the heater. An improper sized flue system can cause unsafe conditions and/or create condensation. The units may be installed as a balanced flue type C heater requiring both a combustion air inlet pipe and a flue pipe or as a power vented heater type B where the combustion air is taken from the space where heater is installed and which requires only a flue pipe exhausting to outdoors. All products of combustion must be flued to outdoor atmosphere. Each heater installed as a type B appliance must be fitted with an individual flue pipe and the combustion air inlet opening must be provided with a protection grill. Each heater installed as a type C appliance must be fitted with an individual combustion air/flue pipe system. Type ... - Page 13 Condense drain A condensation drain must be fitted to both the unit and the flue outlet to properly drain all Attention condensation. The condensation drain from the flue must be constructed from non‐corrodible material not less than 20mm diameter. Copper or copper based alloys must not be used for condensation drain. Consult section 8 : Condensation drain pipe connections 7.2 POWER VENTED INSTALLATIONS (type B appliances) If the air heater is to be installed as a type B Figure 6 : appliance, air for combustion will be taken from Approved appliances type B within the space where the heater is installed.
