GAS INFRA-RED TUBE HEATER STW-JZ / IW SERIES INSTALLATION INSTRUCTIONS 1. GENERAL Installation of the STW-JZ / IW Series gas-fired tube heaters must conform to all manufacturers heating installation design procedures including ventilation. All installations in Canada must conform to local and national code requirements including the current CSA-B149.1-00 installation code for gas burning appliances and equipment, and Canadian Electrical Code part 1 CSA C22.1 latest edition must be observed.
The following tube lengths and corresponding BTU/hr input ratings are available: CAUTION ! TABLE 1 MODELS AVAILABLE RECOMMENDED SIZES FOR STANDARD PATIO APPLICATIONS BTU/HR INPUT O’ TO 45OO’ ABOVE SEA LEVEL OVERALL HEATER LENGTH* (FT) APPROX.
4. BURNER & TUBE KIT ASSEMBLY CHARTS NOTE: STW-JZ / IW Series Burners require 120V supply—Now available with a 24V option Stand-Alone Tube Kits require no additional Tube Kits Primary Tube Kits require at least one additional Secondary Tube Kit Secondary Tube Kits require a Primary Tube Kit Secondary Tube Kit TW-1010-JZ can also be used as a 10ft extension kit. The installer may need to remove the turbulator (refer to Turbulator Chart in the I & O Manual.
5. PRE-INSTALLATION SURVEY The STW-JZ / IW 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. For best results, whenever possible, place burner and combustion chamber in coldest area. One side panel of the burner accommodates the gas and electrical connections into the burner making it much more difficult to remove.

7. SYSTEMS INCORPORATING 90O ELBOWS AND 180O ELBOWS The 90o elbows are shipped as a kit with one coupler, one reflector and one plate hanger, for 1800 elbows you must order 2 x 900 kits. An optional angle mounting elbow kit is also available and must be ordered with elbow kits. The Reflectors must be secured to each of the plate hangers, See FIG: 6 (PAGE 8). The STW-JZ / IW Series radiant tube heater can be installed in configurations as illustrated in FIGURE 2.
8. SUSPENSION SYSTEM 1) Survey the available structural supports, considering the system configuration and heat requirements of the area to establish the optimum heater location.

FIGURE 15 HANGER ARRANGEMENTS NOTE: Except for the vent end plate hanger, all hangers must be installed with the cavity side facing the burner end of the system - the cavity side of the vent end hanger must face the vent 1 1 Page Page 13 14 GP-MSJW-CX-07B STW-JZ / IW Manual RD: Sept, 2005 RL: 7B KH

11. FLUE VENTING THIS STW-JZ / IW 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 (COMBUSTION AIR IS A REQUIREMENT FOR CAR WASH INSTALLATIONS).
The heater is designed to operate with single wall 4” diameter 26 gauge minimum exhaust vent. 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. FIGURE 17 The total maximum allowable combined length of vent and combustion air duct is 80' for STW-JZ / IW 200, 175, 155 and 130, and 50' for STW-JZ / IW 110, 80, 60 and 45.
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 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 TruTemp Thermostat, a line voltage Thermostat or by an “ON/OFF" switch.
17. LIGHTING INSTRUCTIONS Refer to the lighting instructions on the outside cover of the burner housing. Again, if the unit locks out 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. 18. RECOMMENDED MAINTENANCE 1.
19. SEQUENCE OF OPERATION - GASLITER MICRO 50N The STW-JZ / IW 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.
