manual abstract


• To install the heater in accordance with the clearances to combustibles. • To furnish all needed materials not furnished as standard equipment. • To plan location of supports, vents and air intakes. • To provide access for servicing. • To provide the owner with a copy of this Installation, Operation and Service Manual. • To never use heater as support for a ladder or other access equipment and never hang or suspend anything from heater. • To ensure there is adequate air circulation around the heater and to supply air for combustion, ventilation and distribution in accordance with local codes. • To provide a method that ensures that the air flow through the heat exchanger is within the acceptable range indicated on the rating plate prior to energizing the heater, and that such air flow continues at least 90 seconds after the heater is de-energized. 2.1 Wall Tag A laminated wall tag is included with the heater as a permanent reminder of the safety instructions and the importance of the required clearances to combustibles. Affix the tag by peeling off the backing of the adhesive strips on the rear surface and position the tag on a wall near the heater. A copy of the wall tag (P/N 91039831) is illustrated on the back cover. Know your model number. Model number is found on the heater and throughout the Installation, Operation and Service Manual. 2.2 Corrosive Chemicals Caution: Do not use heater in an area containing corrosive chemicals. Avoid the use of corrosive chemicals to ensure a longer life of the burner, heat exchanger and other parts. 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 sub-contractor, or the owner identifies the presence of combustible materials, corrosive chemicals or halogenated hydrocarbons* anywhere in the premises. * Halogenated Hydrocarbons are a family of chemical compounds characterized by the presence of halogen elements (fluorine, 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 life span of the heater components will be greatly reduced. An 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 Applicable Codes All appliances must be installed in accordance with the latest revision of the applicable standards and national codes. This refers also to the electric, gas and venting installation. Note: Additional standards for installations in public garages, aircraft hangars, etc. may be applicable. SECTION 3: CRITICAL CONSIDERATIONS SECTION 3: CRITICAL CONSIDERATIONS 3.1 Basic Information UHD[X][S][R] heaters have automatic ignition burners for ON/OFF operation only. 3.2 Manufactured Units Gas-fired, power-vented duct furnace with tubular heat exchanger. Units shall have a minimum of 82% thermal efficiency. The standard unit shall consist of a non-separated combustion design with an aluminized heat exchanger. Design and heat exchanger alternatives shall be offered as follows: • Separated Combustion: A separated combustion unit shall feature an enclosed, sealed burner box. A piece of flexible air duct connects this burner box to a flange on the cabinet. Combustion air should be ducted from outside the heated space, with the ductwork connecting to the unit with the use of the flange. • Stainless Steel Heat Exchanger: A stainless steel heat exchanger unit shall consist of heat exchanger tubes, heat exchanger tube supports, heat exchanger tube plates and vent box produced of 409 stainless steel. 3.3 Location and Suspension All models: • Must be installed indoors. • Must be installed on the positive pressure side of the air circulation blower. • Must be installed in a level position with horizontal discharge. • May be mounted on a shelf of non-combustible material. • May be suspended from above (See Page 8, Figure 3) or from wall brackets of sufficient strength to support the heater as listed in the Dimension Data Table on Page 37, Section 15.1. • Must be installed in a manner which allows access to all serviceable components. See Page 3, Figure 1 for details. 3.4 Minimum Required Installation Clearances Clearances around the heater and vent must be as indicated on Page 3, Figure 1 and Page 11, Figure 4 through Page 14, Figure 9 to ensure access for servicing, and correct operation. 3.5 Clearances to Combustibles WARNING Fire Hazard Some objects can catch fire or explode when placed close to heater. Keep all flammable objects, liquids and vapors the required clearances to combustibles away from heater. Failure to follow these instructions can result in death, injury or property damage. Clearances must be as indicated on Page 3, Figure 1. If clea...
