Page 5: Gas Supply Lines
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 8: Clearance To Combustibles
Clearance To Combustibles It is important to observe minimum clearance to combustibles at all times to avoid any possibility of property damage or personal injury. Clearances must be maintained from vehicles parked beneath heaters. Signs should be posted identifying any possible violation of the clearance distances from the heater in vehicle areas. -

Page 10: Installation Detail
Installation Detail 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 11 Installation Detail Figure 5 Installation Configuration for 80,000 BTUH Model Series-LA/LX/LXR Page 9 6/15/2010...

Page 13: Installation Sequence
Installation Sequence A general ordered sequence for installation is provided below for reference. • Locate hanging chain at predetermined suspension points in the structure. It is required that the • first hanging point be 2" inches to 8" inches from the burner mounting flange, the second Reflector End Cap Reflector... - Page 14 Installation Sequence Locate Tube and Reflector Hangers every 10' thereafter. 8' - 9' Coupling Should Be Loosely Fitted Install "J" Bolt at first hanger Tube Flange Combustion Tube Reflector Support Tube & Reflector 3" Hangers Figure 8 • Suspension mechanism must allow for lateral tubing expansion. A minimum 12" inch length welded link chain with a working load limit of at least 200 lbs.
- Page 15 Installation Sequence • Install the tube and reflector support hanger on the chain with “S-hooks”. • Place the first (flanged, aluminized) tube in the first two hangers. Be sure the flange is toward the intended burner location. The other end of the tube should have the first coupling already loosely fitted.
- Page 16 Installation Sequence • Locate the burner gasket provided, bolt the burner in place on the tube flange with provided hardware. Burner must never be installed in a tilted position. The sense electrode of the burner cup should be in the 12 o’clock position. •...
- Page 17 Installation Sequence Note: In order to obtain smoothly sealed coupling liners, tighten each of the coupling bands progressively and alternately. Tightening one band completely before the other may result in an undesirable wrinkle in the liner. Note: 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.
- Page 18 Installation Sequence • If required by the heater layout, install 90° elbows or U-tube where indicated. Refer to Figure 16 for details. Note: Elbows or U-bends are typically installed without reflectors. To reduce the above clearance to combustibles distance use mitered reflectors (see figure 15) and refer to Clearance to Combustibles information.
- Page 19 Installation Sequence • If used, install the Mitered reflector as shown below. 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.

Additionally, the gas distribution piping must be designed according to local and national ordinances. Generally (low pressure) systems designed with a maximum ½"... -
Page 27: Electrical Wiring
Electrical Wiring General Requirements Heaters are normally controlled by line voltage or low voltage (24V) thermostats. 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. Heaters may also be controlled with a manual line switch or timer switch in place of the thermostat. -
Page 28: 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. -
