Figure 3.2 • Heater Packaging • 2 Pieces Burner Control Box Emitter Assembly and Reflector Box ! WARNING Improper suspension of the tube heater may result in collapse and being crushed.
QTS Series 3.0 Installation • Heater Assembly Heater Assembly Assembly prior to hanging: With this method, the use of two saw horses or a raised table or bench surface is beneficial (the emitter assembly and reflector box may also be used). 1 Lay the emitter assembly (TP-6082) across the horses or bench with the exchanger connection hanging bracket extended out over the edge (See Detail ‘A’) NOTE: Use of the foam shipping blocks will help protect the emitter coating and reflectors.
3.0 Installation • Heater Assembly • Preparing Points for Hanging QTS Series Installing the Reflector Assembly NOTE: Prior to installing the reflector, relocate the saw horses to support the burner control box and the tubes beneath the u-end reflector. 1 Align the reflector end cap holes (2) with the corresponding burner control box studs (see Detail 2. 3 4 5 ‘C’-Step 1). NOTE: Do not remove the existing nuts on studs.
QTS Series 3.0 Installation • Preparing Points for Hanging • Hanging Types Preparing Points for Hanging 1 Transfer the heater’s three hanging locations to the ceiling where the unit is to be installed and mark hanging points. 2 Prepare mounting surface. If necessary attach additional support blocks and drill holes (Figure 3.5). 3 Fasten beam clamp, screw hook or other type of suspension anchor to hanging point. 4 Attach and close S-hook (P/N: S-HOOK) and #1 double-loop chain (P/N: THCS) to anchor.
QTS Series 3.0 Installation • Hanging Pre-Assembled Unit Hanging Pre-Assembled Unit 1 Raise the assembled unit from assembly station to prepared hanging location.

QTS Series 3.0 Installation • Venting Venting ! WARNING Insufficient ventilation and/or improperly sealed vents may release gas into the building which could result in health problems, carbon monoxide poisoning or death. Improper venting may result in fire, explosion, injury or death. Seal vent pipes with high temperature sealant and three (3) #8 sheet metal screws. Vent enclosed spaces and buildings according to the guidelines in this manual and applicable national, state, provincial and local codes.
QTS Series 3.0 Installation • Venting • Unvented Operation Unvented Operation ! WARNING Not for residential use. The use of unvented radiant tube heaters in residential indoor spaces may result in property damage, serious injury or death. Use unvented operation in commercial and industrial installations with proper ventilation rates only. When using an unvented configuration (commercial & industrial use only), consider the following: • A factory supplied vent cap/diffuser (P/N: WVE-GALV) must be used.
QTS Series 3.0 Installation • Venting • Sidewall Venting Sidewall Venting Guidelines: Vent Pipe Angle • To prevent moisture from entering the heater system, slope the vent pipe downward toward the outlet 1/4 in. per foot of length. Do not pitch the heater. • **Vent must extend beyond any combustible overhang if the vent is less than 36 in. below the combustible overhang. Figure 3.11 • Sidewall Venting Requirements Building Overhang** Sidewall Heater B to C Adapter 6 in. min.** 36 in. min.
QTS Series 3.0 Installation • Venting • Sidewall Operation Vent Termination United States: • Vent must terminate a minimum of 4 ft. (1.2 m) below, 4 ft. (1.2 m) horizontally from, or 1 ft. (30 cm) above any window or door that may be opened or gravity air inlet into the building. • Vent must terminate a minimum of 3 ft. (.9 m) above any forced air inlet that is located within 10 ft. (3.1 m). • The bottom of the vent terminal must be located a minimum of 12 in.
QTS Series 3.0 Installation • Venting • Rooftop Venting Rooftop Venting Guidelines: Vent Locations and Clearances • Separate air intake duct from vent pipe a minimum of 4 ft. (1.2 m) by placing vent pipes higher than adjacent air intake duct. • Venting may utilize standard B-vent cap. • The vent terminal must extend a minimum of 2 ft. (.6 m) above the roof. Figure 3.12 • Rooftop Venting - Side View Vent Cap 24 in. Min.* Roof* Storm Collar Adjustable Roof Flashing 1 in. Minimum Clearance 1 in.
QTS Series 3.0 Installation • Venting • Common Venting Common Venting • When joining two heaters to a common vent, a staggered arrangement or a dual exhaust assembly (P/N: YSM) must be used so by-products of one heater do not flow into the adjoining vent of the other heater. • 6 in. diameter double-wall Type B-vent and 6 in. vent cap must be used. • Common vented heaters must be controlled with the same thermostat. Do not operate individually. Figure 3.
QTS Series 3.0 Installation • Combustion Air Requirements Combustion Air Requirements Combustion air may be supplied to the heater by indoor or outdoor means. If using combustion air intake from indoors, the required volume of the space must be a minimum of 50 ft3 per 1000 BTU/h (4.8 m3 /kW) unless the building is of unusually tight construction. If the building is of unusually tight construction with air infiltration rates of less than 0.
