Propane gas and propane tank(s) are to be furnished by the user.

Use this heater only with a propane vapor withdrawal supply system. See Chapter 5 of the Standard for Storage and Handling of Liquefied Petroleum Gas, ANSI/ NFPA 58. Your local library or fire department will have this booklet.

The amount of propane gas ready for use from propane tanks varies. Two factors decide this amount:

1.The amount of propane gas in tank(s)

2.The temperature of tank(s)

The chart below shows the number of 100 pound tanks needed to run this heater. Do not operate this product with any tank smaller than 100 pounds.

Less gas is vaporized at lower temperatures. You may need two or more 100 pound tanks or one larger tank in colder weather. Your local propane gas dealer will help you select the proper supply system. The minimum surrounding air temperature rating for each heater is -20°F (-29°C).

!WARNING

Review and understand the warnings in the Safety Information Section, pages 2 and 3. They are needed to safely operate this heater. Follow all local codes when using this heater.

!WARNING

Test all gas piping and connections for leaks after installing or servicing. Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.

1.Provide propane supply system (see Propane Supply above).

2.Connect POL fitting on hose/regulator assembly to propane tank(s). Turn POL fitting counterclockwise into threads on tank. Tighten firmly using

7/8" wrench. IMPORTANT: Tighten regulator with vent pointing down. Pointing vent down protects regulator from weather damage.

ROPANE CONSTRUCTION HEATERS specifications

Desa Ropane Construction Heaters are renowned for their efficiency and reliability in providing heat in various construction environments. These powerful heaters are specifically designed to meet the demands of the construction industry, where maintaining a suitable temperature is crucial for worker safety and the integrity of materials.

One of the main features of Desa Ropane heaters is their robust construction. Built to withstand the rigors of job sites, these heaters are made from durable materials that can resist wear and tear. This durability ensures that the heaters can operate in harsh conditions without compromising on performance.

Desa Ropane heaters utilize advanced infrared technology to produce heat. This technology allows for efficient heating, as infrared rays directly warm people and objects, rather than the air. This makes them especially effective in large, open spaces where conventional heating methods might struggle to maintain warmth. By focusing on direct heat transfer, these heaters minimize energy waste and reduce heating costs.

Another characteristic of Desa Ropane heaters is their user-friendly design. Many models come equipped with easy-to-use controls that allow operators to adjust the temperature settings quickly. This feature is particularly beneficial for construction workers who may need to respond rapidly to changing weather conditions. Additionally, several models feature built-in safety mechanisms, such as tip-over switches and overheat protection, ensuring safe operation even in the most challenging environments.

Portability is yet another strength of Desa Ropane heaters. Many models are lightweight and fitted with wheels, making it easy to move them around job sites as needed. This flexibility is invaluable in dynamic construction environments where heating requirements may change throughout the day.

Moreover, Desa Ropane heaters operate quietly, which is an essential feature for construction sites that may need to comply with noise regulations or where workers require a more peaceful working atmosphere.

In summary, Desa Ropane Construction Heaters are crafted with durability, efficiency, and user convenience in mind. With their infrared heating technology, built-in safety features, exceptional portability, and quiet operation, they are ideal solutions for meeting the heating needs in construction settings. Their reliable performance makes them a go-to choice for contractors and construction companies looking to ensure a warm and safe working environment during cold months.
