SECTION 3: CLEARANCES TO COMBUSTIBLES

WARNING

Fire Hazard

Keep all flammable objects, liquids and vapours 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.

3.1 Required Clearances to Combustibles

Clearances are the required distances that

combustible objects must be away from the heater to prevent fire hazards. Caution should be used when running the system near combustibles. 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 around the heater and flue must be as indicated on Page 6, Figure 3, to ensure access for servicing, and correct operation. If clearances to combustibles are not indicated, then installation clearances apply.

Check the clearances 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 petrol or other combustible materials including flammable objects, liquids, dust or vapours away from this heater or any other appli- ance.

•The stated clearances to combustibles repre- sents a surface temperature of 32°C (90° F) above room temperature. Building materials with a low heat tolerance (such as plastics, vinyl sid- ing, canvas, tri-ply, etc) may be subject to degra- dation at lower temperatures. It is the installer’s responsibility to assure that adjacent materials are protected from degradation.

•Maintain clearances from heat sensitive equip- ment and workstations.

•Maintain clearances from vehicles parked below the heater.

•Maintain clearances from swinging and over- head doors, overhead cranes, vehicle lifts, parti-

tions, 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 main- tain required clearances from the heater to the combustibles. Signs must be posted adjacent to the heater thermostat. In the absence of a ther- mostat, signs must be posted in a conspicuous location.

•Consult local Building Inspector, Fire Insurance Carrier or other authorities for approval of pro- posed installation when there is a possibility of exposure to combustible airborne materials or vapours.

•Hang heater in accordance to the minimum

suspension requirements on Page 10, Section 6 and Page 11, Figure 4 through Page 12, Figure 5.

•Affix the tag on a wall near the heater.

With an integrated control system, it can easily adapt to changing operational demands, making it a preferred choice for businesses that experience variable occupancy levels. Its quiet operation minimizes workplace noise, and its energy-efficient design significantly cuts operational costs.

CTCU 7 is specifically engineered for smaller spaces without compromising performance. This unit features compact dimensions while still delivering adequate air flow for localized heating and ventilation needs. The advanced temperature control algorithms allow for precise adjustments, ensuring a comfortable environment even in tight areas.

CTCU 27 stands out with its advanced technology that includes integrated smart controls. This model offers real-time monitoring and data analytics to optimize performance and enhance energy efficiency. Its ability to connect with existing building management systems makes it an appealing choice for modern facilities aiming to improve sustainability initiatives.

The CTCU 11 is characterized by its user-friendly interface and maintenance accessibility. It is built with durable materials that extend its lifespan, ensuring long-term reliability. This unit is ideal for applications where regular maintenance is challenging, as its design allows for easy access to all critical components.

In summary, Roberts Gorden's CTCU series encompasses a range of units catered to various industrial needs. With features focusing on efficiency, flexibility, and user-friendliness, these models deliver high-quality air management solutions to improve indoor environments while reducing energy consumption.
