Venting Codes, Balanced Flue Construction

SECTION 3: PLANNING

3.4Venting Requirements 3.4.1 System Requirements

The CGTH-Series heater must be installed with the venting system supplied or with the optional venting kit available from Roberts-Gordon. DO NOT connect this heater to a separate chimney and do not com- mon vent with any other fuel burning appliance.

The CGTH-Series heater employs a balanced flue/air venting duct system and must conform to the follow- ing length requirements:

Maximum Length:10' (3048 mm) Minimum Length:2' - 6" (760 mm)

Maximum Elbows:Two (2) with natural gas units, one (1) with propane gas units

3.4.2 Venting Codes

WARNING

Carbon Monoxide Hazard

Heater must be exhausted outside. Use materials supplied.

This heater needs fresh air for safe operation and must be installed so there are provisions for adequate combustion and ventilation air.

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

The location, size, installation and termination of vents, as well as the required safe distances from combustibles when penetrating combustible walls, must comply with local codes and recommendations of the local gas company. United States: Refer to National Fuel Gas Code, ANSI Z223.1 - latest revi- sion (same as NFPA Bulletin 54). Canada: Refer to CSA B149.1 and B149.2: Installation Codes for Gas Burning Appliances.

3.4.3 Balanced Flue Construction

The balanced flue consists of a 3" (80 mm) diameter flue which is concentrically positioned inside a 5" (125 mm) diameter vent pipe (See Figure 3). The 5" (125 mm) diameter vent supplies outside air for com- bustion while the 3" (80 mm) diameter flue carries the products of combustion from the heater.

The balanced flue is applicable for both horizontal and vertical venting arrangements. Vertical venting will require the optional roof venting kit available from Roberts-Gordon.

3.5Non-Residential Installations 3.5.1 Aircraft Hangars

The CGTH-Series heater may be used in certain areas of aircraft hangars. Installation in aircraft hangars must be in accordance with the following codes: United States: Refer to Standard for Aircraft Hangars, ANSI/ NFPA-409 - latest revision. Canada: Refer to Standard CSA B149.1 and B149.2.

•Heaters in aircraft storage or service areas must be installed a minimum of 10' (3048 mm) above the upper surface of wings or engine enclosures of the highest aircraft which may be housed in the hangar. (This should be measured from the bottom of the heater to the top of the wing, or engine enclosure, whichever is highest from the floor).

•In other sections of aircraft hangars, such as shops or offices, heaters must be installed a minimum of 8' (2438 mm) above the floor.

•Heaters installed in aircraft hangars shall be located so as not to be subject to damage by aircraft, cranes, movable scaffolding or other objects.

•When installed over hoists, the required safe dis- tances from combustibles must be maintained from the uppermost point of the combustible materials placed on the hoist.

3.5.2 Public Garages

The CGTH-Series heater may be used in public garages. Installation in public garages must be in accor- dance with the following codes: United States: Standard for Parking Structures NFPA-88A - latest revision or the Code for Fuel Dispensing Facilities and Repair Garages, NFPA-30A - latest revision. Canada: Refer to CSA B149.1 and B149.2: Installation Codes for Gas Burning Appliances.

•Heaters must be installed a minimum of 8' (2438

mm)above the floor. Required safe distances to

CGTH-40, CGTH-50, CGTH-30 specifications

Roberts Gordon is a renowned manufacturer known for its innovative heating solutions, particularly in the realm of infrared heaters. Among their product lineup, the CGTH series, which includes the CGTH-50, CGTH-40, and CGTH-30 models, exemplifies high-performance technology tailored specifically for industrial and commercial applications.

The CGTH series is designed for versatility and efficiency, offering advanced features that enhance the heating experience in various environments. One of the standout features of these heaters is their infrared technology, which provides targeted warmth, making them ideal for large, open spaces such as warehouses, factories, and sporting facilities. Infrared heaters work by directly heating objects and people in their path rather than the air, ensuring quicker warmth and greater energy efficiency.

Each model offers different heating capacities, with the CGTH-50 boasting a maximum output of 50,000 BTUs, the CGTH-40 providing up to 40,000 BTUs, and the CGTH-30 generating 30,000 BTUs. This variety allows users to choose a model that best fits their heating needs based on the size and requirements of their space.

The units are designed for easy installation, featuring a modular design that allows for both indoor and outdoor applications. Moreover, the heaters can be integrated with various control systems, including programmable thermostats and remote management, enhancing user convenience and optimizing energy usage.

A critical aspect of the CGTH series is its emphasis on durability and safety. Each model is crafted using high-quality materials that can withstand harsh conditions typically found in industrial settings. Additionally, they incorporate safety features such as over-temperature protection and robust mounting brackets, ensuring peace of mind during operation.

Another important characteristic of the CGTH series is their efficiency. By minimizing energy waste and targeting heat output precisely, these heaters can significantly lower energy costs, making them not only environmentally friendly but also economically advantageous for businesses.

In summary, the Roberts Gordon CGTH-50, CGTH-40, and CGTH-30 infrared heaters stand out for their innovative technology, energy efficiency, and reliability. Whether for large commercial spaces or industrial environments, these heating solutions are designed to provide the comfort and performance required for any operation. With their robust features and customizable options, they remain a top choice for effective heating solutions in diverse settings.
