SECTION 8: VENTING

8.3 Horizontal Venting

FIGURE 22: Tube Termination

In noncombustible walls only, vent terminal (P/N 02537801-1P) may be used.

For 4'' (10 cm) vents in either combustible or noncombustible walls, use Tjernlund VH1-4 (P/N 90502100) or equivalent insulated vent terminal. Follow the manufacturer's instructions for proper installation.

For 6'' (15 cm) common vents in either combustible or noncombustible walls, use Tjernlund VH1-6 (P/N 90502101) or equivalent insulated vent terminal.

Follow the manufacturer's instructions for proper installation.

8.4 Vertical Venting

For 4'' (10 cm), an approved vent cap (P/N 90502300) must be used.

For 6'' (15 cm) common vent, an approved vent cap (P/N 90502302) must be used.

For common vertical venting of more than two heaters, See Page 37, Section 8.10.

A vent shall not extend less than 2' (.6m) above the highest point where it passes through a flat roof of a building.

8.5 Unvented Operation Tube Termination

Turndown type vent terminal with a screen must be installed at the exhaust end of the tube. Vent terminal design shall not incorporate backdraft flap.

8.6 Length Requirements

The maximum vent length allowed is 45' (13.7 m). The maximum outside air supply duct length allowed is 45' (13.7 m).

The total vent length, plus outside air duct length, plus any extensions to minimum heat exchanger lengths, cannot exceed 65' (19.8 m).

Vent length should be limited to less than 20' (6 m). If using vent lengths greater than 20' (6 m), condensation will form in the vent pipe. Insulation and additional sealing measures (high temperature silicone at all seams) are required. Optional heat exchanger beyond minimum lengths is considered as vent length for length determination.

Subtract 15' (4.6 m) of maximum allowed vent or duct length per vent elbow if more than two are used.

CTH2-40 CTH2-60, CTH2-175, CTH2-150, CTH2-100, CTH2-80 specifications

Roberts Gorden is a reputable name in the field of heating and energy efficiency, and its CTH2 series of infrared radiant heaters—including the CTH2-150, CTH2-80, CTH2-125, CTH2-100, and CTH2-175—are a testament to innovation and quality. Designed for commercial and industrial spaces, these heaters provide effective and efficient heating solutions tailored to various needs.

The CTH2 series employs advanced infrared heating technology, which radiates warmth directly to objects and individuals in the space rather than heating the air. This method ensures rapid heat-up times and energy conservation, making the heaters ideal for workshops, warehouses, and other large areas where traditional heating systems may be inefficient.

One of the main features of the CTH2 series is its high thermal efficiency. The heaters convert a significant portion of the energy consumed into usable heat, resulting in lower operational costs and a reduced carbon footprint. The CTH2 models utilize durable components designed to withstand the rigors of industrial environments, ensuring longevity and reliable performance.

The CTH2-150, CTH2-80, CTH2-125, CTH2-100, and CTH2-175 models vary in output capacity and design, providing flexibility for different heating requirements. The maximum heat output ranges significantly among the models, with the CTH2-175 offering the highest thermal output, making it suitable for larger spaces or areas requiring immediate and intense heating. Conversely, the CTH2-80 is ideal for smaller areas or those that require less heat.

Installation versatility is another key characteristic of the CTH2 series. These heaters can be mounted from the ceiling or installed horizontally or vertically, accommodating different building layouts and operational needs. The heaters are also designed for easy maintenance, featuring accessible components to facilitate routine checks and repairs.

The CTH2 series incorporates safety features such as overheat protection and flame safeguard systems, ensuring safe operation even in busy industrial settings. Additionally, their sleek and modern design allows them to integrate seamlessly with existing infrastructure without detracting from the overall aesthetic of the space.

In conclusion, Roberts Gorden’s CTH2 series—including the CTH2-150, CTH2-80, CTH2-125, CTH2-100, and CTH2-175—represents a pinnacle of infrared heating technology.
