5. PRE-INSTALLATION SURVEY The Schwank STS-p 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 with at least minimum clearances between the reflector surface and combustibles as shown in FIGURE 1, TABLE 3, ON PAGE 5.

7. SYSTEMS INCORPORATING 90O ELBOWS AND 180O ELBOWS The STS-p 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 SECTION 11 (PAGE 15): Re: Flue venting. Both the 90o and 180o elbows are shipped as a kit with one coupler and two end plate hangers to close off the reflector ends each side of 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 (PAGE 8). Wire hangers are provided to support reflectors and tubes along the full length between the two end plate hangers, SEE FIGURES 4,5 (PAGE 8) and FIGURES 7,9 (PAGE 9). (The STS-p 45-10 DOES NOT require wire hangers, as the reflector is supported at both ends by the end plate hangers).

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 4 (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 series is approved for both direct 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.
When venting horizontally, the flue vent system should slope downwards approximately 1/4" per foot toward the vent terminal, starting at the termination of the radiant tube. For horizontal through the wall venting, the approved Schwank 4" or 6" vent terminal should be used. Install the flue vent terminal 18" from the outside wall to the inside end of terminal opening. The flue vent terminal used must be of the approved types supplied by Schwank or supplied by an approved "B" vent manufacturer.
Where the vent pipe passes through areas where the ambient temperature is likely to produce condensation of the flue gases, t h e vent pipe shall be insulated with a suitable material as approved and specified by the insulation manufacturer. Check with Schwank Tech. Support as to the maximum vent temperature requirements. The vent system must always be adequately supported to prevent sagging.
For ease of installation, this heater has been provided with a fresh air intake duct hood. It can be used as an outdoor intake hood to bring combustion air to the heater from outside. Or to use air directly from the room, it must be installed over the intake flange on top of the burner. If drawing in fresh air from outside, it is recommended as per common Engineering practice, that the combustion air intake duct be insulated. Do not use flexible dryer hose for air inlet duct.
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) 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, 31) 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 - HONEYWELL S87J-1034 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. 5. After completing the 30 second pre-purge cycle the DSI control generates high voltage to the Spark Igniter, and 24 volts to energize the Gas Valve. 1a.
