SECTION 8: VENTING

WARNING

Carbon Monoxide Hazard

Heaters installed unvented must be interlocked with sufficient building exhaust.

Heaters must be installed according to the installation manual.

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

WARNING

Cut/Pinch Hazard

Wear protective gear during installation, operation and service.

Edges are sharp.

Failure to follow these instructions can result in injury.

8.1 General Venting Requirements

This heater must be vented in accordance with the rules contained in this manual and with the following national codes and any state, provincial or local codes which may apply:

United States: Refer to National Fuel Gas Code NFPA 54/ANSI Z223.1 - latest revision.

Canada: Refer to Natural Gas and Propane Installation Code CSA B149.1 - latest revision.

Exhaust end of heater will accept a 4'' (10 cm) vent pipe using the vent adapter (P/N 90502700). To prevent leakage of condensation, install the vent adapter with the seam on top and seal the joint using a high temperature silicone sealant.

All vent joints should be sealed using suitable product such as General Electric RTV106 or Permatex Form-a-Gasket red high temperature silicone adhesive sealant.

For outdoor installations, vent caps must be installed at inlet and flue end. (See Page 37, Section 8.7).

Any portion of vent pipe passing through a combustible wall must have an approved thimble to conform with the above listed codes.

Vent pipe must be sloped downward away from the burner 1/2'' (1 cm) for every 20' (6 m).

The heater may be individually vented or common vented. When venting horizontally, a maximum of two heaters can be commonly vented. See Page 39, Section 8.10. When venting vertically, a maximum of four heaters can be commonly vented. See Page 40, Section 8.11.

The heater may also be installed unvented in certain circumstances according to building ventilation codes. Refer to the above codes and Page 36, Section 8.2 for further information. Unvented operation also requires compliance with the clearances to combustibles given on Page 10, Figure 12.

The bottom of the vent or air intake terminal shall not be located less than 1' (.3 m) above grade level.

The vent shall not terminate less than 7' (2.1 m) above grade where located adjacent to public walkways.

Vent terminal must be installed at a height sufficient to prevent blockage by snow, and building materials protected from degradation by flue gases.

Secure all joints with #8 x 3/8 sheet metal screws. Seal all joints with high temperature silicone sealant.

Vent terminal must be beyond any combustible overhang.

HE-125, HE-150, HE-100, HE-40, HE-175 specifications

Roberts Gordon is renowned for its innovative heating solutions, and among its standout offerings are the HE-125, HE-175, HE-100, HE-150, and HE-40 heaters. These products exemplify cutting-edge technology and efficiency designed for commercial and industrial applications.

The HE-125 and HE-175 variants are among the top-rated infrared heaters available. They utilize advanced infrared technology to provide direct heating to objects, reducing the need to heat the entire ambient air volume. This method results in energy savings while delivering consistent warmth where it's needed most. The HE-125 model has a heating capacity of 125,000 BTU, while the HE-175 pushes this to 175,000 BTU, making them suitable for larger spaces like warehouses and manufacturing facilities.

The HE-100 and HE-150 heaters are designed for flexibility and efficiency in a range of operational environments. These models support a wide range of input fuels including natural gas and propane, making them an adaptable choice for various setups. The HE-100 has an output of 100,000 BTU, and the HE-150 follows with 150,000 BTU. Both units are engineered with robust construction materials, ensuring durability and longevity, while also featuring advanced safety systems to prevent overheating and other hazards.

In contrast, the HE-40 heater stands out for smaller spaces, making it an ideal option for garages, workshops, or smaller commercial environments. With a capacity of 40,000 BTU, it effectively delivers consistent warmth without the excessive energy consumption associated with larger units.

All Roberts Gordon models prioritize energy efficiency, often meeting or exceeding current energy codes. They incorporate advanced control systems that allow precise temperature regulation, further optimizing energy use. Additionally, the heaters are designed with minimal maintenance needs, featuring durable components that ensure long-term reliability and performance.

With a legacy of quality and innovation, Roberts Gordon continues to set the standard in infrared heating technology. The HE series exemplifies a commitment to efficiency, safety, and versatility, making them suitable for a wide range of commercial and industrial applications. Whether heating a vast warehouse or a small workshop, these heaters provide reliable performance tailored to user needs.
