Compliance to the standard is mandatory. The calculation for seasonal efficiency takes into account air flow, temperature rise across the heat exchanger, electrical power consumption as well as the usual thermal efficiencies. HEM gas fired heat exchange modules placed on the market after 1st January 2018 when operated at the stated design parameters comply with the thermal efficiency element of the standard. Air handling unit manufacturers will need to have due regard for other requirements of the standard including, but not limited to, power consumption. Customers will note that in pursuit of the increased efficiency HEM heaters which are to be used to provide a heat source for comfort purposes are no longer available in on/off configuration, high/low heat output will be standard with modulation as an option.

Temperature HEM modules are rated at a maximum temperature rise of 35 C for the HEM-NVx and 25 C for the HEM-SL and both with a maximum air off temperature of 70 C. Controls Heat Exchanger As standard all HERM units are supplied with approved safety controls including high limit protection, flame monitoring and multi try ignition. A four pass (HEM-NVx) tubular heat exchanger and a two pass (HEM-SL) heat exchanger assembly manufactured from aluminised steel formed, swaged and expanded without recourse to stress inducing welding. (AISI 409 grade stainless steel option available) Heat enable and fan over-run protection are the responsibility of the installer/user. On/off and high/low units require a 230v signal whilst modulating modules are supplied with an interface board and require a 0 10v DC signal to effect modulation. Burners Multi in-shot burners matched to each tube assembly and manifolded to a common gas valve and ignition system, itself complete with flame monitoring and safety controls and supplied ready for use with natural gas (G20). Alternative LPG propane (G31) firing available to order. Burner Enclosures are available for weatherproofed external ( see page 10 ) and internal plant room applications. Fully galvanized steel construction in either self finish or durable epoxy powder coated paint finish to BS 10-A-05 as standard Other colours are available priced upon application. Flue Both the HEM-NVx and HEM-SL modules have the benefit of fan-assisted flues. Onward flue systems can be the addition of close-coupled flue terminals or, if application requires, an extended system flue. In the event that an extended flue is required then please consult Powrmatic. Approvals HEM units are type tested and CE approved. In addition heaters placed on the market subsequent to 1st January 2018 meet the seasonal efficiency requirements of ErP Lot 21 Tier 1. Airflow To assist designers the attached duty tables confirm the minimum airflow necessary for safe and efficient operation as well as providing guidance on maximum airflows and pressure loss.

11 Your Installer Guide General The following notes are provided as a guide, however installers and operators should fully acquaint themselves with the more detailed guidance provided in the relevant installation manual. For copies of such manuals please consult our technical department or visit our website - Standards All Powrmatic HEM modules should be installed, commissioned and operated with due regard to appropriate regulations including but not limited to BS6230:2011, Gas Safety (Installation and Use Regulation) 1998, other relevant Codes of Practice, the possible requirements of Local Authorities, Fire Officers and insurers. Application HEM modules are typically applied in four distinct configurations and due regard is required for each to ensure safe and reliable operation as well as compliance to necessary regulations. Typical application types are as follows External Internal Plant room Dedicated compartment within an air handling unit or process heater which itself may be externally located, internally located or within a plant room Location and Position Modules should be firmly fixed within their environment, free from vibration and protected from the effects of rain, spray or water ingress. External modules should be fitted with a dedicated Powrmatic burner enclosure. Consideration should also be given to flue routes and points of exit, gas, electrical and where applicable control connections. Modules should not be installed in hazardous areas or areas where there is a foreseeable risk of flammable or corrosion inducing particles, gases or vapours being drawn into the combustion air or main fan circuits. Areas where special consideration or advice may be required could include but is not limited to - where de-greasing solvents are present, even in minute concentrations where paint spraying is carried out where styrenes or other laminating products are used where airborne silicone is present where petrol engined vehicles are stored or maintained where dust is present (ie wood working or joinery shops) where high levels of extract persist Installation in such areas may be possible under specific conditions. Please consult our technical department for further information. Plant Room or Enclosure Locations Specific requirements exist where modules are installed within plant rooms or enclosures, including within dedicated compartments of air handling units or process heaters. Such requirements cover the provision of positive ductwork connections as well as ventilation for combustion air and general plant room or enclosure ventilation. It is recommended that you consult with the installation manual prior to installation. Combustion Air & General Ventilation Within the United Kingdom mandatory regulations apply concerning the provision of combustion air and general heater ventilation. Please consult the installation manual for further details. Ductwork Duct connections to and from the module should be such that the airflow across the entirety of the heat exchanger is uniform. Sharp turns and/or restrictions close to the module should be avoided. Condensing Mode Care should be taken to ensure that when modules are operated with airflows or heat output rates which will generate the production of condensate then provision should be made with respect to the specification of heat exchanger material and for the removal of condensate. If in doubt then please consult our technical department. Fan Over-Run All HEM modules require the provision of a fan over-run facility, by others, to ensure that the heat exchanger is correctly cooled at the end of each firing cycle. If in doubt then please consult our technical department. Gas Connections Care should be taken when sizing pipework to ensure that minimum gas inlet pressures are not compromised under dynamic load conditions. Isolating valves and service unions should be provided for each module and pipework installed with due regard for relevant standards and Codes of Practice. Fuel consumption and output figures contained within this brochure are at maximum firing rate and based upon nett calorific values as - Natural gas (G20) nett CV MJ/m3 - LPG Propane (G31)nett CV 88.0 MJ/m3 Flue Powrmatic HEM modules requires a separate flue of the appropriate size and type. Systems may be installed in either the horizontal or vertical plane and maximum lengths apply and should be strictly observed. The inclusions of bends and/or provision of combustion air intake ductwork will reduce the permissible length. For further information please consult the Installation, Operation and Maintenance manual or Powrmatic Technical. Flues must be adequately supported and terminated with the approved terminal assembly, with due regard to the point of exit and its proximity to any windows, doors or ventilation intakes etc. Guarantee Powrmatic HEM Heat Modules are provided with a comprehensive guarantee. For United Kingdom sales the heater has the benefit of a two year parts and one year labour guarantee. All guarantees are subject to terms and conditions. 2 YEAR PARTS WARRANTY Installation Clearances Particular clearances may be necessary for the correct and safe function of the module as well as for maintenance purposes. Such clearances are confirmed in the relevant installation manual YEAR 10 YEAR LABOUR WARRANTY TIME RELATED HEAT EXCHANGER WARRANTY
