SECTION 3: CLEARANCES TO COMBUSTIBLES 3.1 Required Clearances to Combustibles

Clearances are the required distances that combusti- ble objects must be away from the heater to prevent serious fire hazards. Combustibles are materials, which may catch on fire and include common items such as wood, paper, rubber, fabric, etc. Maintain

clearances to combustibles at all times for safety.

Clearances for all heater models are located on the burner assembly and on Page 6, Figure 3 through Page 8, Figure 10 in this manual. Check the clear- ances on each burner for the model heater being installed to make sure the product is suitable for your application and the clearances are maintained. Read and follow the safety guidelines below:

•Keep gasoline or other combustible materials including flammable objects, liquids, dust or vapors away from this heater or any other appli- ance.

•The stated clearances to combustibles represents a surface temperature of 90° F (32° C) above room temperature. Building materials with a low heat tolerance (such as plastics, vinyl siding, can- vas, tri-ply, etc) may be subject to degradation at lower temperatures. It is the installer’s responsibil- ity to assure that adjacent materials are protected from degradation.

•Maintain clearances from heat sensitive equipment and workstations.

•Maintain clearances from vehicles parked below the heater.

•Maintain clearances from swinging and overhead doors, overhead cranes, vehicle lifts, partitions, storage racks, hoists, building construction, etc.

•In locations used for the storage of combustible materials, signs must be posted to specify the maximum permissible stacking height to maintain required clearances from the heater to the com- bustibles. Signs must be posted adjacent to the heater thermostat. In the absence of a thermo- stat, signs must be posted in a conspicuous loca- tion.

•Consult local Fire Marshal, Fire Insurance Carrier or other authorities for approval of proposed installation when there is a possibility of exposure to combustible airborne materials or vapors.

•Hang heater in accordance to the minimum sus- pension requirements.

•If the radiant tubes must pass through the building structure, be sure that adequate sleeving and fire stop is installed to prevent scorching and/or fire hazard.

WARNING

Fire Hazard

Keep all flammable objects, liquids and vapors the minimum required clearances to combustibles away from heater.

Some objects will catch fire or explode when placed close to heater.

Failure to follow these instructions can result in death, injury or property damage.

CRV-B-4, CRV-B-2, CRV-B-6, CRV-B-8 specifications

Roberts Gorden is renowned for its innovative heating solutions, particularly the CRV series of infrared radiant heaters, which include models CRV-B-2, CRV-B-4, CRV-B-6, and CRV-B-8. These heaters are designed to provide effective and efficient heating, making them ideal for various industrial, commercial, and agricultural applications.

One of the standout features of the Roberts Gorden CRV series is its advanced infrared heating technology. Unlike conventional heating systems that heat the air, infrared heaters warm objects and people directly, allowing for a more energy-efficient and comfortable environment. This makes the CRV series particularly effective in large spaces, such as warehouses, manufacturing facilities, and greenhouses.

The CRV-B models are engineered for versatility and can be mounted in various configurations, including horizontal and vertical placements, providing installation flexibility. Each model is available in different sizes and heating outputs, ensuring that users can select a unit tailored to their specific heating requirements. The CRV-B-2, for instance, is ideal for smaller spaces, while the CRV-B-8 offers higher power for larger areas.

Moreover, these heaters come equipped with advanced control systems that allow for precise temperature regulation. The units can be integrated with building management systems, enabling users to monitor and adjust settings remotely. This feature not only enhances comfort but also contributes to energy savings, as the heaters can be programmed to operate only during necessary hours.

Structural durability is another significant characteristic of the CRV series. Constructed with high-quality materials, the heaters are designed to withstand the rigors of industrial environments while maintaining optimal performance over time. The reflective surfaces enhance heat distribution, ensuring that warmth is evenly distributed throughout the space.

Safety is paramount with Roberts Gorden’s CRV heaters. They are designed with built-in safety mechanisms, including overheat protection and automatic shut-off features to prevent accidents.

Overall, the Roberts Gorden CRV-B-2, CRV-B-4, CRV-B-6, and CRV-B-8 models exemplify cutting-edge infrared heating technology, delivering effective, efficient, and reliable heating solutions tailored to diverse applications. With a combination of flexibility, advanced control capabilities, and safety features, these heaters are an excellent choice for anyone in need of powerful heating solutions.
