    Introduction Gas Supply Lines Gas supply pipe sizing must be in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 in the US and CAN/CGA B149.1 and B149.2 Installation Codes in Canada. A 1/8" inch NPT plugged tap must be installed in the gas line connection immediately upstream of the burner farthest from the gas supply meter to allow checking of system gas pressure.

  • Page 10: Clearance To Combustibles

    Clearance to Combustibles A general clearance of 18” (0.5 m) in every direction is recommended for servicing only around each Burner, Vacuum Pump, and End Vent Cap air supply (at the far end of each Radiant Branch) also to ensure adequate air flow in and around the Heating System. In addition to this it is very important to observe the minimum clearance to combustibles at all times to avoid any possibility of property damage or personal injury.

  • Page 12: Installation

    Installation Installation Sequence Generally, there is no unique sequence for installation of the burner or heat exchanger. A review of the job site will usually indicate a logical installation order. However, time and expense can be saved if installation is begun at the most critical dimension, watching for interference from overhead doors, cranes, auto lifts etc.

  • Page 17 Installation NSTALLATION  Always use all the hangers supplied. As a rule the combustion tube (first tube) utilizes 2 hangers and thereafter 1 hanger per 10' section. It is required that the first hanging point be 2" to 8" from the burner mounting flange, and tube weld seam must face down, refer to Figure 10for more details.
  • Page 18 Installation  Tighten the cradle loops of the first hanger with the “J-Bolt” found in the burner box, to snugly hold the combustion tube from rotating see Figure 12. Note: For all coupling joints, ensure that the tube joint is in the center of the coupling length, and that the overlap joint of the coupling is above the centerline of the tube.
  • Page 19 Installation EATER AND AFFLE NSTALLATION  Locate the burner gasket provided, bolt the burner in place on the tube flange with provided hardware.

  • Page 22 Installation Note:Reflectors should overlap adjacent reflectors 4" to 6". Be sure not to tile reflector sections; that is, reflector sections must be either above both adjacent reflector sections, or below both adjacent reflector sections. Refer toFigure 18.

  • Page 23 Installation  Secure every second reflector overlap together with a minimum of 2 - #8 x 3/8" long screws (not supplied), and secure reflector to the reflector bracket at this point by tightening down #8 x 1¼" screws supplied with reflector brackets (Figure 19). The remaining reflector overlapjoints and reflector brackets are left loose to accommodate system movement.
  • Page 24 Installation “U-T ” I LBOW AND NSTALLATION  If required by the heater layout, install 90° elbows or U-tube where indicated. Refer to Figure 21 for details. Note: Elbows or U-tubesare typically installed without reflectors. To reduce the above clearance to combustibles distance use miter reflectors (see Figure 22) and refer to Clearance to Combustibles information.
  • Page 25 Installation ITERED EFLECTOR NSTALLATION  If used, install the Mitered Reflector as shown below (Figure 22). Assemble Corner Bracket to Mitered Reflectors as shown Fasten Mitered Reflectors with 4 - #8 x 3/8" Screws Mitered Reflector Sections should overlap standard Reflectors.

  • Page 32: Combustion Air Supply (Optional)

    Venting / Combustion Air Ducting Combustion Air Supply (Optional)  An outside combustion air supply is strongly recommended if the building space encloses a negative pressure due to exhaust etc. or if the building contains materials which would expose the heater to halogenated hydrocarbon atmospheres.

  • Page 33: Outdoor Installation

    Outdoor Installation (LXR M UTDOOR NSTALLATION ODELS When a heater is to be mounted outdoors it must be installed in such a way that wind will have minimum effect on its movement. This consideration is intended to eliminate undue stress on the gas flex connector. In all cases a fresh air hood must be used in conjunction with a vent terminal of the approved type, and all connections must be sealed with a high temperature sealant that can withstand 400°F.

  • Page 34: Gas Piping

    Gas Piping General Requirements  The gas meter and service must be sufficiently large to supply gas to the connected building gas load including the heating equipment and any other gas fired equipment. Additionally, the gas distribution piping must be designed according to local and national ordinances. Generally (low pressure) systems designed with a maximum ½"W.C.

  • Page 35: Electrical Wiring

    Electrical Wiring General Requirements Heaters are normally controlled by line voltage (120V) or low voltage (24V) thermostats. Line voltage thermostats are wired directly while low voltage thermostats use a relay. In all cases, heaters must be grounded in accordance with the National Electric Code, ANSI/NFPA 70 in the US, and the Canadian Electric Code, CSA C22.1 in Canada, and must comply with all local requirements.

  • Page 37: Burner Operation

    Burner Operation Starting Sequence of Operation  Turn the thermostat up. When the thermostat calls for heat, the blower motor will energize.  When the motor approaches nominal running RPM, the air-proving switch closes and activates the ignition module.  The ignition module, after a pre-purge period of approximately 30 seconds, energizes the igniter. Additionally, the gas valve is energized for this ignition trial period of 15 seconds.
