The heaters are typically installed directly into the space to be heated with ducted applications satisfied using the centrifugal fan option. Suitable for either natural or LP gases, heaters can be specified/arranged for on/off, high/low or modulated heat outputs. fficiencies avourable levels of fuel usage and reduced emissions are a key element of NVx heater design. dditionally, all heaters have efficiencies which meet or exceed the requirements of current uilding Regulations. fficiencies can be further enhanced with the selection of the modulating burner option. abinet The heater unit is of unitary construction and provided with a separate compartment with a full width hinged and lift-off door giving easy access to heater function controls, gas valve and burner. The cabinet is finished with durable epoxy powder coat stove baked paint. Heat xchanger our pass tubular assembly manufactured from aluminised steel formed, swaged and expanded without recourse to stress inducing welding. 409 and 316 grade stainless steel options available. ontrols s standard, Powrmatic heaters are supplied with high temperature limit protection as well as connections for heat and, where applicable, fan-only operation. or enhanced control the heaters may be connected to one of our compatible environmental control stations. These are available in three options: 200L (control of single units) Tamper-proof digital control featuring optimised start/stop, digital time switch, electronic and frost protection thermostats. Remote temperature sensor option available. 300 ulti (control of multiple units) The 300 multi is functionally identical to the 200L with the added ability to control up to five heaters from a master 300 control. or ease of installation and to reduce installation time and cost slave pcbs are factory fitted with connections between master and slave enabled with low voltage control cable. Powrtrol (control of single units) s an alternative to the control units, Powrtrol control stations provide a digital time switch with mechanical day and frost protection thermostats and a switched fan-only option for summer operation. Heaters controlled using Powrtrol do not qualify for nhanced apital llowances. Note: Interconnecting wiring for all controls is the responsibility of the installer.

12 Your Installer uide eneral 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. or copies of such manuals please consult our technical department or visit our website - Standards ll Powrmatic NVx heaters must be installed, commissioned and operated with due regard to appropriate regulations including but not limited to S 6230, relevant odes of Practice, the possible requirements of Local uthorities, ire Officers and insurers as well as Powrmatic s installation manual. Position & Location Powrmatic NVx heaters can be drop rod suspended via purpose designed 10 suspension fixing points, attached to our optional wall support brackets or positioned on a level non-combustible base. In all cases it is important that all supporting structures have due regard to the relevant weight loadings. onsideration should also be given to flue routes and points of exit, gas, electrical and control connections, the throw characteristics of the heater, issues of public access and the siting of environmental control stations and/or remote temperature sensors where the position needs to be representative of the zone temperature to which they refer. Heaters 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. reas 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 (i.e. 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 nclosure Locations It is recommended that you consult with our technical department.

Where a heater is installed in room sealed mode (i.e. where both the flue exit and combustion air and positively connected to atmosphere) then there is no specific requirement for combustion air ventilation. However, depending upon location, provision for general ventilation may still be a necessity. If the heater is installed in flue only mode and directly within the heated space and where that heated space has a natural ventilation rate greater than 0.5 air changes per hour then combustion air and general heater ventilation is probably not required. If the heated space has a natural ventilation rate of less than 0.5 air changes per hour then either natural ventilator openings or mechanical ventilation will be required. Please consult the installation manual for further details. Installation learances Particular clearances may be necessary for the correct and safe function of the heater as well as for maintenance purposes. Such clearances are confirmed in the relevant installation manual. lue Powrmatic NVx heaters can be installed in either room sealed or flue only mode. ach heater requires a separate flue and/or combustion air intake system of the appropriate size and type. Installers are reminded that type approval has been granted for these appliances on the basis that they are fitted with Powrmatic NVx flue systems. aximum lengths apply and should be strictly observed. Systems may be installed in either the horizontal or vertical plane. In either case the number of bends kept to a minimum and regard must be given to the reduction in permissible length with the addition of each bend. The flue must be adequately supported and terminated with the approved terminal assembly, with due regard to the point of exit and it s proximity to any windows, doors or ventilation intakes etc. Pipework are should be taken when sizing pipe work to ensure that minimum gas inlet pressures are not compromised under dynamic load conditions. Isolating valves and service unions should be provided for each heater and pipe work installed with due regard for relevant standards and odes of Practice. uarantee Powrmatic NVx heaters are provided with a comprehensive guarantee covering both the heater and the heat exchanger. or United Kingdom sales the heater has the benefit of a two year parts and one year labour guarantee whilst the heat exchanger assembly has a ten year time related sliding scale warranty. ll guarantees are subject to terms and conditions.
