Product ApprovalROBERTS GORDON appliances have been tested and CE certified as complying with the essentialrequirements of the Gas Appliance Directive, The Low Voltage Directive, The ElectromagneticCompatibility Directive and the Machinery Directive for use on natural gas and L.P. gas when installed,commissioned and maintained in accordance with these instructions.These instructions refer to appliances designed to operate in the European Union.Appliances designed for other countries (Non European Union) are available on request.This appliance must be installed in accordance with the local and national codes in force and usedonly in a sufficiently ventilated space, as specified in these instructions.Before installation, check that the local gas distribution systems, nature of gas and pressure, andadjustment of the appliance are compatible.1
COMBAT CTU U NIT H EATERS INSTALLATION OPERATION AND S ERVICE MANUALSECTION 1: HEATER SAFETYYour Safety is Important to Us!This symbol is used throughout themanual to notify you of possible fire,electrical or burn hazards. Please payspecial attention when reading andfollowing the warnings in these sections.Installation, Service and Annual Inspection of heatermust be done by a registered installer/contractorqualified in the installation and service of gas-firedheating equipment.Read this manual carefully before installation,operation, or service of this equipment.This heater is designed for heating non-residentialindoor spaces. Do not install in residential spaces.These instructions, the layout drawing, local codesand ordinances, and applicable standards that applyto gas piping, electrical wiring, venting, etc., must bethoroughly understood before proceeding with theinstallation.SECTION 2: INSTALLER RESPONSIBILITY To install the heater, as well as the gas and electrical supplies, in accordance with applicablespecifications and codes. Roberts-Gordonrecommends the installer contact a localbuilding inspector, Fire Officer or insurancecompany for guidance. To use the information given in the manualtogether with the local and national codes toperform the installation. To install the heater in accordance with theClearances to Combustibles of this heater. To furnish all needed materials not furnishedas standard equipment. To plan location of supports, flues and airintakes. To provide access to burners for servicing. To provide the owner with a copy of thisinstallation, commissioning, operation andservice manual. To never use heater as support for ladder orother access equipment and never hang orsuspend anything from heater. To ensure that there is sufficient ventilation inthe area to comply with the requirements ofall relevant local and national codes.2.1 Clearances to CombustiblesIn all situations, clearances to combustibles must bemaintained. Caution must be used when running theheater near combustible materials such as wood,paper, rubber, etc. A wall tag is on the back cover ofthis manual as a permanent reminder of the safetyinstructions and the importance of the requiredclearances to combustibles. Affix the tag on a wallnear the heater.22.2 Corrosive ChemicalsCAUTIONDo not use heater in an area containing corrosivechemicals.Corrosive chemicals will damage the burner andheat exchanger parts.Failure to follow these instructions can result inproperty damage.Roberts-Gordon cannot be responsible for ensuringthat all appropriate safety measures are undertakenprior to installation; this is entirely the responsibilityof the installer. It is essential that the contractor, thesub-contractor, or the owner identifies the presenceof combustible materials, corrosive chemicals orhalogenated hydrocarbons* anywhere in thepremises.* Halogenated Hydrocarbons are a family of chemicalcompounds characterized by the presence of halogenelements (fluorine, chlorine, bromine, etc.). These compounds are frequently used in refrigerants, cleaningagents, solvents, etc. If these compounds enter the airsupply of the burner, the lifespan of the heater components will be greatly reduced. Warranty will be invalid ifthe heater is exposed to halogenated hydrocarbons.2.3 National Standards and Applicable CodesAll Appliances must be installed in accordance withthe latest revision of applicable standards and localand national codes. This refers also to the electric,gas and venting installation. Note: Additionalstandards for installations in Public Garages, AircraftHangars, etc. may be applicable.
SECTION 3: CRITICAL C ONSIDERATIONSSECTION 3: CRITICAL CONSIDERATIONS3.1 Basic InformationCTU heaters have automatic ignition burners forON/OFF operation only.3.2 Location and SuspensionAll models: Must be installed indoors. Must be installed in a level position. May be mounted on a shelf of non-combustiblematerial. (See Page 5, Section 4 and Page 10,Figure 3 for support points) May be suspended from above (See Page 10,Figure 3) or from wall brackets of sufficientstrength to support the heater as listed in theDimension Data Table on Page 5, Section 4.1.Drop rods must be a minimum of 10 mm diameter mild steel. Four suspension points (M10nuts) are located on top of the heater. Must be installed in a manner which allows thehinged door to be fully opened to provide accessto all serviceable components.individual and correctly sized sealed flue system(See Page 11, Section 6).No other appliance may be connected to the flue.For room sealed installation the air intake must bethe same size sealed system and the flue/air intakemust terminate at an approved concentric wall orroof terminal.3.3 Minimum Required Installation ClearancesClearances around the heater and flue must be asindicated on Page 4, Figure 1, Page 11, Figure 4through Page 12, Figure 7 to ensure access forservicing, and correct operation.3.4 Clearances to CombustiblesClearances must be as indicated on Page 4, Figure1. If no clearances to combustibles are indicatedthen installation clearances apply.3.5 VentilationIt is important to ensure that there is adequate aircirculation around the heater to supply air forcombustion, ventilation and distribution inaccordance with local and national codes.3.6 Gas SupplyIt is important that the gas supply pipe is sizedcorrectly to provide the inlet pressure as stated onthe heater data plate. The gas supply pipe andelectrical connections must not support any of theheater's weight.3.7 Electrical SupplyA permanent 230v 50Hz electrical supply is requiredat the main electrical terminals. The heater alsorequires suitable energy controls in accordance withSection 10.3.8 FlueChoose heater siting to allow for the proper locationof the flue. Each heater must be fitted with an3
