5. PRE-INSTALLATION SURVEY The Schwank STSp-WP heating system must have gas piping of the correct diameter, length, and arrangement to function properly. For this reason, a layout drawing is neces- Carefully survey area to be heated. For best results, whenever possible, place burner and combustion chamber in coldest area. 6. MOUNTING CLEARANCES This heater must be mounted with minimum clearances between the reflector surface and combustibles, as shown in FIGURE 1 (page 5), TABLE 3 (page 5).

7. SYSTEMS INCORPORATING 90O ELBOWS AND 180O ELBOWS The STSp-WP Series radiant tube heater can be installed in configurations as illustrated in FIGURE 2. (below) with a maximum of two 90o or one 180o elbow per heater. The use of radiant elbows reduces the total maximum vent allowable. See FLUE VENTING in SECTION 11 (page 14). Both the 90o and 180o elbows are shipped as a kit, with one coupler kit and two end plate hangers to close off the reflector ends around the elbow(s).
8. SUSPENSION SYSTEM End plate hangers are provided to support reflectors and tubes at both ends of heater, that is at burner and at flue, see FIGURE 3 (below), FIGURES 4,5,6 (pages 7, 8). Wire hangers are provided to support reflectors and tubes along the full length between the two end plate hangers, SEE FIGURES 4,5 (pages 7, 8) and FIGURES 7,9 (page 9). The system configuration and available support locations must be considered to locate the radiant tubes correctly.

9. BURNER AND TUBE INSTALLATION With all hangers suspended at the same height, insert first aluminized tube section, through 4" hole in first end plate hanger and onto wire hanger. End plate hanger should butt against the sight glass on the bottom of the tube, SEE FIGURE 5 (PAGE 8). Bolt burner to flange on first tube section, SEE FIGURE 10 (BELOW). Subsequent lengths of tube can then be installed, joining them together one inside the other.

11. FLUE VENTING NOTE: The STSp-Wp series is approved for both direct vented and indirect vented applications. The system must not be operated in a negative air condition, unless combustion air is brought in from outside directly to the burner. If a severe negative pressure is experienced or anticipated, order heater requesting custom Air Switch c/w Air Hose from Schwank. * Ensuring you specify the correct heater model number when ordering.
The total maximum allowable length of vent and combustion air duct is 80' for STSp-WP 200, 175, 155 and 130, and 50' for STSp-WP 110, 80 and 60. The total maximum allowable vent and duct is reduced by ten feet for every 90o vent elbow installed in the vent or duct. Should the system be installed with a 90 or 180 degree elbow in the radiant tube, 10ft or 20ft respectively must be deducted from the length of vent and duct. Neither the flue vent nor the combustion air duct is to exceed 50ft in length.
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. The vent system must be adequately supported to prevent sagging. FIGURE 19 FLUE VENT CONNECTION FLUE VENT END OF TUBE The end of the tube is swaged and will directly accommodate regular “C” vent and fittings for venting to outside. The “C” Vent connection to the radiant tube end must be secured with sheet metal screws.
For ease of installation, this heater has been provided with a fresh air intake duct hood. It is used as an outdoor intake hood to bring combustion air to the heater from outside. Do not use flexible dryer hose for air inlet duct. The corrugated sides of this tubing add too much restriction to the air flow and will result in heater shut down by air switches.
The supply system should be checked first with heater turned "OFF", followed by another check with heater turned "ON". 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. IMPORTANT: The minimum supply-line pressure at the inlet to the heater regulator must not, in any instance, be lower than 5.0 inches of water column pressure for natural gas and 11.
14. HEATER EXPANSION The Btu/hr input and the tube length determine the overall expansion that occurs in a tube system. A typical infrared tube installation will expand toward both the Burner and the vent end. In order to address this issue it is suggested that the gas line, flue vent, and combustion air intake (if used) shall be installed in such a manner, that the normal expansion of the heater will be accommodated.
15. ELECTRICAL AND THERMOSTAT WIRING (SEE WIRING DIAGRAMS PAGES 23, 26) 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 tube heater requires 120V, 60 HZ electrical power sized for 145VA. The heater can be controlled by the Schwank Tru-Temp Thermostat, a line voltage Thermostat or by an “ON/OFF" switch.
17. LIGHTING INSTRUCTIONS NOTE: Refer to the lighting instructions on the inside On initial installation, the unit cover of the burner housing. Again, if the may lock out on safety owing to unit goes off on safety, main power to the the length of time required to unit must be manually interrupted for a 30 bleed air from the gas piping second reset period before the heater can be system. restarted. 18. RECOMMENDED MAINTENANCE 1.
19. CA SERIES SEQUENCE OF OPERATION - GASLITER MICRO 50N CA Series: The STS-p Burner with direct spark ignition, sequence is as follows : 1. Upon a call for heat by the line voltage Thermostat or "ON/OFF" switch, the Blower and the 120/24 volt Transformer are powered simultaneously with 115 volts. 7. Once the flame sensor determines there is a steady flame established, the spark igniter is then de-energized. 1a.

GENERAL INSTALLATION INSTRUCTIONS The following instructions are a guide to installation only, and supplement, but do not replace design instructions given in the Schwank Engineering Manual. Since most installations will differ in many details, these instructions are general. Sound judgment must be exercised and careful supervision is essential to assure that the installation will be made in the best manner possible for trouble-free operation and at the very least cost.
2. Assemble two reflector end plate hangers by attaching 1 of the reflector end plates to the hanger plate using the supplied slotted screws and nuts. If the system is longer than 10 feet, additional reflector plate hangers must be assembled. To assemble a reflector plate hanger, attach 2 of the reflector end plates to opposite sides of the hanger plate and screws using the supplied slotted screws and nuts. The reflector end plate hangers are used on each end of the total system.
3. If any of the sections of reflector need to be angled, this can be accomplished by placing the slotted screw in any of the mounting holes situated in a circular pattern. Each section of reflector can be individually adjusted independent of the previous or next shades orientation. 4. Slide the reflector end plate hangers and reflector plate hangers on the tubes before assembling the tubes. An additional coupling and reflector end plate hanger will be required for each additional tube. 5.
WARNING Installation of the turbulator is imperative to the warranty of the tubes. Install the turbulator in the last section of tubes. If installed in the first section of tube, it will cause tubes to burn out. This will void the warranty. See typical arrangements for turbulator requirements and placement.
