5. PRE-INSTALLATION SURVEY The SEM(U) / IT(U) heating system must have gas piping of the correct diameter, length, and arrangement to function properly. For this reason, a layout drawing is necessary. Carefully survey area to be heated, and for best results, whenever possible, place burner and combustion chamber in coldest area. 6. MOUNTING CLEARANCES This heater must be mounted and positioned to maintain the minimum clearance to combustible materials as shown in FIGURE 1 & TABLE 3.

7. SYSTEMS INCORPORATING 90° ELBOWS The 90° elbows are shipped as a kit with one clamp and two end caps to close off the reflector ends each side of the elbow (s). The Reflectors must be secured with four screws to each of the end caps. (see FIG 10) The SEM / IT Series radiant tube heater can be installed in configurations as illustrated in Fig:2 (below) with a maximum of two 90° elbows per heater. The use of radiant elbows reduces the total maximum vent allowable. (See SECTION: 11) Flue Venting.
8. SUSPENSION SYSTEM The system configuration and available support locations must be considered in order to locate the radiant tubes correctly. Labour and material can be reduced by locating (system configuration permitting) directly under structural members such as joists, steel or wood beams, etc. Chain is recommended for hanging the tube system, connecting the hangers to beam support as illustrated in FIGURE 3 (below).

9.2. 175,000 & 200,000 Btuh INPUTS - FIRST TUBE JOINT CONNECTION Models with inputs 175,000 & 200,000 Btuh have alumatherm as the first section with a welded Flange, the second section is unpainted aluminized steel. The second tube has two slots in the un-swaged end, and fastens to the first tube using an Accu-Seal clamp (SEE FIGURE 8). The final position of the Accu-Seal clamp is flush to the end of the second tube with the ‘reaction block’ located in the center of the two slots in the tube.
10. REFLECTOR INSTALLATION SEM / IT: After burner and tubes have been installed, slide the reflectors one at a time into the wire hangers. As each successive reflector is installed on an in-line installation, the ends of the reflectors will overlap to provide continuous coverage over the entire tube system. The overlapping joints MUST BE FASTENED TOGETHER with a sheet metal screw. Note that for both horizontal and angle mounting, the tube must be level.

11. FLUE VENTING THIS SEM(U) / IT(U) SERIES IS APPROVED FOR BOTH DIRECT AND INDIRECT VENTING APPLICATIONS. THE SYSTEM MUST NOT BE OPERATED WITHIN A NEGATIVE AIR CONDITION, UNLESS COMBUSTION AIR IS BROUGHT IN FROM OUTSIDE DIRECTLY TO THE BURNER.
The heater is designed to operate with single wall 4” diameter 26 gauge minimum exhaust vent. When venting horizontally, the flue vent system should slope downwards approximately 1/4" per foot toward the vent terminal, start- ing at the termination of the radiant tube. When vent and combustion air are taken through the roof, the exhaust vent should always terminate higher than the combustion air intake, to prevent recycling the products of combustion back into the heater.
Where the vent pipe passes through areas where the ambient temperature is likely to produce condensation of the flue gases, the vent pipe shall be insulated with a suitable material as approved and specified by the insulation manufacturer. Check with the manufacturers Technical Support as to the maximum vent temperature requirements. The vent system must always be adequately supported to prevent sagging.
Do not install filters on the combustion air intake. For ease of installation, this heater has an optional fresh air intake duct hood. It can be used as an outdoor intake hood to bring combustion air to the heater from outside. If drawing in fresh air from outside, it is recommended as per common Engineering practice, that any single wall pipe exposed to cold air must be insulated to prevent condensation.
DO NOT use pressures greater than 1/2 psig. to pressure check the heater. TEST FOR LEAKS: All gas piping and connections must be tested for leaks after the installation is completed. Apply soap suds solution to all connections and joints and if bubbles appear, leaks have been detected and must be corrected. DO NOT USE A MATCH OR OPEN FLAME OF ANY KIND TO TEST FOR LEAKS. NEVER OPERATE THE HEATER WITH LEAKING CONNECTIONS.
14. HEATER EXPANSION Due to the characteristics of tube heaters, the installer must allow for 1” expansion for every 10’ length of tube. In order to address this characteristic, it is suggested that the gas line, flue vent, and combustion air intake (if used) be installed in such a manner, that normal expansion of the heater will be accommodated.
15. ELECTRICAL AND THERMOSTAT WIRING (SEE WIRING DIAGRAM) Wiring must be done in accordance with local codes. The total load of all heaters must be considered in determining the required contact rating of the controlling thermostat or switch. Each individual tube heater requires 120 Volts 60 Hz electrical power sized for 145VA. The heater can be controlled by a line voltage thermostat or "ON/OFF" switch. WARNING: The heater must be electrically grounded in accordance with the current Electrical Code.
17. SEQUENCE OF OPERATION / FLAME RECOVERY/ SAFETY LOCKOUT Start up - Heat Mode Flame Failure of Established Flame When the thermostat is set above the ambient temperature, 120 VAC is supplied to the L1 terminal. When this occurs the control will power up and perform a self-check routine and begin a pre-purge*, if selected. Following the pre-purge, the gas valve is energized and sparks commence until flame is detected or the Trial For Ignition (TFI) period expires.
18. LIGHTING INSTRUCTIONS LIGHTING SEQUENCE: Refer to the lighting instructions on the outside cover of the burner housing. Again, if the unit goes off on safety, main power to the unit must be manually interrupted for a 30 second reset period before the heater can be restarted. NOTE: On initial installation, the unit may lock out on safety owing to the length of time required to bleed air from the gas piping system. • • • • • • Rotate gas valve knob to ON position. Set Thermostat to the desired setting.
