SECTION 9: GAS PIPING

WARNING

Fire Hazard

Tighten gas hose fittings to connect gas supply according to Figure 23.

Gas hose can crack when twisted.

Gas hose moves during normal operation.

Use only 36" (91 cm) long connector of 1/2" or 3/4" nominal ID.

Connector supplied with heater for U.S. models (not with Canadian models).

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

WARNING

Explosion Hazard

Leak test all components of gas piping before operation.

Gas can leak if piping is not installed properly.

Do not high pressure test gas piping with heater connected.

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

There is an expansion of the tube with each firing cycle, this will cause the burner to move with respect to the gas line. This can cause a gas leak resulting in an unsafe condition if the gas connection is not made strictly in accordance with Figure 23.

Meter and service must be large enough to handle all the burners being installed plus any other connected load. The gas line which feeds the system must be large enough to supply the required gas with a maxi- mum pressure drop of 1/2" wc. When gas piping is not included in the layout drawing, the local gas sup- plier will usually help in planning the gas piping.

Gas lines must meet applicable codes:

United States: The Flexible Stainless Steel Gas Hose (US models) supplied with the heater is certi- fied per the Standard for Connectors for Gas Appli- ances, ANSI Z21.24/CSA 6.10 - latest revision. Canada: The Rubber Type 1 Gas Hose (Canadian models) optional with the heater is certified as being in compliance with the Standard for Elastomeric Composite Hose and Hose Couplings for Conducting Propane and Natural Gas, CAN/CGA 8.1 - Latest revision.

•Check the pipe and tubing ends for leaks before placing heating equipment into ser- vice. When checking for gas leaks, use a soap and water solution; never use an open flame.

Install the gas hose as shown in Figure 23. The gas hose accommodates expansion of the heating sys- tem and allows for easy installation and service of the burner. Before connecting the burners to the sup- ply system, verify that all high pressure testing of the gas piping has been completed.

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.
