BB / D . B . . . IMPORTANT BEFORE CONNECTING THE GAS TO THE HEATER 1. Connect to the supply tank or manifold in accordance with the latest edition of National Fuel Gas Code (ANSI Z223.1), and local building codes. Authorities having jurisdiction should be consulted before the installation is made. (In Canada, refer to the latest edition of CAN Standard B.149-1 & -2, Installation Codes for Gas Burning Appliances and Equipment.) 2. Check that the gas fuel on the burner rating

The distance from one end of the elbow to the centerline of the opposite leg is 13" as shown. 3. Join the tube ends of the body sections and the elbow together and secure with tube couplings as described in Section 11. (Optional) 13) ADDING OPTIONAL CORNER REFLECTOR (LTS ONLY) 1. Place the corner reflector over the reflectors of both body sections. 2. Secure by sliding speed clips on the reflector edges. One speed clip is required for each side of reflector. 3. The corner reflector can be

Secure by sliding the speed clips onto the reflector edges. Evenly space the speed clips on the sides and top of the reflector to provide a snug fit. Place the foot end reflector (not shown) on the opposite end of the body reflector and secure as described above. DO NOT relocate the tube support/hanger brackets, especially at the control end of the heater. Slide the reflector toward the U-bend and leave a 3” space between the control end reflector and the control box. 2. Attach the control box

Other venting references are in the equipment volume of the ASHRAE Handbook. Form #43155010 Feb-04 -13- SINGLE HEATER VENTING (VERTICAL THROUGH THE ROOF) 1. When venting the heater to outside of building through a roof, use single-wail metal pipe. This is to be constructed of galvanized sheet metal or other approved noncombustible corrosion-resistant material as allowed by state or local codes. 2. A vent passing through a combustible roof shall extend through a 2-inch clearance roof thimble

Maximum heating efficiency and clean combustion will be maintained by keeping the heater clean. To clean the heater, follow these instructions: 1) Turn off all electrical and gas supply to the heater. 2) Open the control box access panel. 3) Clean the access panel, the inside of the control box, the emitter tube and the reflector panels. (Dirty reflectors will reduce output.) 4) Visually inspect the spark electrode. Remove any foreign objects from electrode tip. Set the spark gap to the proper v
