4 SETION 1: HETER SFETY SETION 1: HETER SFETY Your Safety is Important to Us! This symbol is used throughout the manual to notify you of possible fire, electrical or burn hazards. Please pay special attention when reading and following the warnings in these sections. WRNING Installation, Service and nnual Inspection of heater must be done by a contractor qualified in the installation and service of gas-fired heating equipment. Read this manual carefully before installation, operation, or service of this equipment. Failure to follow these instructions can result in death, injury or property damage. wall tag is supplied with the LKHET heater as a permanent reminder of the safety instructions and the importance of the minimum required clearances to combustibles. copy of the wall tag is illustrated on Page 2, Figure 1. Peel off the backing of the adhesive strips on the rear surface of the tag and position the tag on a wall near the LKHET heater (e.g. thermostat or ROERTS GORON Z Microprocessor ontroller). 2.2 Halogenated Hydrocarbons UTION o not use heater in an area containing corrosive chemicals. void the use of corrosive chemicals to ensure a longer life of the burner, tubing and other parts. Failure to follow these instructions can result in property damage. This heater is designed for heating non-residential indoor spaces. o not install in residential spaces. These instructions, layouts, S5601/G 601,local codes and ordinances, and applicable standards that apply to gas piping, electrical wiring, venting, etc., must be thoroughly understood before proceeding with the installation. SETION 2: INSTLLER RESPONSIILITY To install the heater, as well as the gas and electrical supplies, in accordance with applicable specifications and codes. Roberts-Gordon recommends the installer contact a local building inspector or Fire Marshal for guidance. To use the information given in a layout drawing and in the manual together with the cited codes and regulations to perform the installation. To install the heater in accordance with the learances to ombustibles. To furnish all needed materials not furnished as standard equipment. To plan location of supports. To provide access to burners for servicing on all sides, for burner removal. To provide the owner with a copy of this installation, operation and service manual. To never use heater as support for ladder or other access equipment and never hang or suspend anything from heater. 2.1 Low Level User Instructions In all situations, clearances to combustibles must be maintained. Failure to observe clearances to combustibles can result in death, severe injury or property damage. Signs should be posted in storage areas to specify the maximum stacking height of items placed below heater to maintain required clearances to combustibles. Minimum clearances must be maintained from vehicles parked below the heater. aution should be used when running the system near combustible materials such as wood, paper, rubber, etc. onsideration should be given to partitions, storage racks, hoists, building construction,etc. Roberts-Gordon cannot be responsible for ensuring that all appropriate safety measures are undertaken prior to installation; this is entirely the responsibility of the installer. It is essential that the contractor, the subcontractor, or the owner identifies the presence of combustible materials or halogenated hydrocarbons* anywhere in the premises. * Halogenated Hydrocarbons are a family of chemical compounds characterized by the presence of halogen elements (flourine, chlorine, bromine, etc.). These compounds are frequently used in refrigerants, cleaning agents, solvents, etc. If these compounds enter the air supply of the burner, the lifespan of the heater components will be greatly reduced. n outside air supply must be provided to the burners whenever the presence of these compounds is suspected. Warranty will be invalid if the heater is exposed to halogenated hydrocarbons. 2.3 National Standards and pplicable odes ll ppliances must be installed in accordance with the latest revision of S5601/G 601 and other relevant codes. This refers also to the electric, gas and venting installation. Note: dditional standards for installations in Public Garages, ircraft Hangars, etc. may be applicable. 1

5 SETION 3: RITIL ONSIERTIONS SETION 3: RITIL ONSIERTIONS WRNING Fire Hazard Some objects will catch fire or explode when placed close to heater. Keep all flammable objects, liquids and vapors the minimum required clearances to combustibles away from heater. Failure to follow these instructions can result in death or injury. urn Hazard Keep all persons, especially children, away from heater. o not touch any part of the heater. Heater is very hot. Failure to follow these instructions can result in severe injury. 3.1 Minimum Required learances to ombustibles learances are the required distances that combustible objects must be kept away from the heater to prevent serious fire hazards. ombustibles are materials, which may catch on fire and include common items such as wood, paper, rubber, fabric, etc. Maintain clearances to combustibles at all times for your safety. learances for all heater models are located on Page 4, Figure 2 through Page 7, Figure 15 in this manual. heck the clearances on each burner for the model heater being installed to make sure the product is suitable for your application and the clearances are maintained. Read and follow the safety guidelines below: Keep petrol or other combustible materials including flammable objects, liquids, dust or vapours away from this heater or any other appliance. Maintain clearances from heat sensitive material, equipment and workstations. Maintain clearances from vehicles parked below the heater. Maintain clearances from swinging doors, overhead cranes, vehicle lifts, partitions, storage racks, hoists, etc. In locations used for the storage of combustible materials, signs must be posted to specify the maximum permissible stacking height to maintain required clearances from the heater to the combustibles. Signs must be posted adjacent to the heater thermostat. In the absence of a thermostat, signs must be posted in a conspicuous location. onsult local uilding Inspector, Fire Insurance arrier or other authorities for approval of proposed installation when there is a possibility of exposure to combustible airborne materials or vapours. Hang heater in accordance to the minimum suspension requirements on Page 9, Section 4.6 through Page 9, Section 4.8. If the radiant tubes must pass through the building structure, be sure that adequate sleeving and fire stop is installed to prevent scorching and/or fire hazard. 3
