Fuels

WARNING: Use only kero- sene, #1#2 diesel/fuel oil, JET A or JP-8 fuels to avoid risk of ﬁre or explosion. Never use gasoline, naphtha, paint thin- ners, alcohol or other highly ﬂammable fuels.

Do not use heavy fuels such as No. 2 fuel oil or No.

2 diesel. Using heavy fuels will result in:

•clogged fuel ﬁlter and nozzle

•carbon build-up on spark plug

•the need of non-toxic anti-icer in fuel during very cold weather

IMPORTANT: Use a KEROSENE ONLY storage container. Be sure storage container is clean. Foreign matter such as rust, dirt or water will cause ﬂame-out control to shut down heater. Foreign matter may also require you to clean fuel system often.

VENTILATION

WARNING: Follow the mini- mum fresh, outside air ventila- tion requirements. If proper fresh, outside air ventilation is not provided, carbon monoxide poisoning can occur. Provide proper fresh, outside air ventila- tion before running heater.

Fresh Air Opening Requirements

Heater Size	Square Feet Opening
350,000 Btu/Hr	10.5
600,000 Btu/Hr	18.0

Note: If you use more than one heater, provide extra fresh air. Provide a fresh air opening of at least three square feet for each 100,000 Btu/Hr rating.

OPERATION

WARNING:Reviewandunder- stand the warnings in the Safety Information section, page 2. They are needed to safely operate this heater.

TO START HEATER

1.Follow all ventilation and safety information.

2.Locate heater to provide maximum circulation of the heated air. Follow all location require- ments noted in Safety Information, page 2.

3.Fill fuel tank with kerosene, #1#2 diesel/fuel oil, JET A or JP-8 fuels.

4.Attach fuel cap.

5.Set thermostat dial to desired temperature. Note: Thermostat setting must be higher than surrounding air temperature.

6.Plug power cord of heater into three-prong, grounded extension cord. Extension cord must be at least six feet long.

WARNING: Use only a three- prong, grounded extension cord. Use cord with proper wire size to assure 120 volt operation. See Extension Cord Wire Size Requirements below.

Extension Cord Wire Size Requirements 6 to 100 feet long, use 14 AWG rated cord

101 to 200 feet long, use 12 AWG rated cord 201 to 300 feet long, use 10 AWG rated cord 301 to 400 feet long, use 8 AWG rated cord 401 to 500 feet long, use 6 AWG rated cord

7.Plug extension cord into standard 120 volt/60 hertz, three-hole, grounded outlet.

8.The motor will start when extension cord is plugged into outlet. The heater should ignite at once. If heater does not ignite, restart heater. To restart heater, wait 60 seconds, then push in ﬂame-out control reset button. Flame-out control reset button is at rear of heater near power cord (see Figure 4, page 5).

Note:Acold heater may affect the thermostat setting. This thermostat is a general-heating control. It is not intended for precise temperature control.Adjust ther- mostat until heater cycles at the desired setting.

Note: If starting heater for ﬁrst time, you may need to prime the pump. If equipped, slightly open bleed- er valve of pump to allow air to escape. Quickly close valve once fuel is seen. Wipe up any excess fuel. If equipped with canister fuel ﬁlter, remove the canister bottom and ﬁll with fuel. Reassemble ﬁlter. Wipe up any excess fuel. You may also have to do this after taking heater out of storage.

KEROSENE HIGH PRESSURE PORTABLE FORCED AIR HEATERS specifications

Desa Kerosene High Pressure Portable Forced Air Heaters are engineered to deliver efficient and effective heating solutions for a variety of applications. These heaters stand out for their portability, high heating capacity, and adaptability to different environments, making them ideal for construction sites, warehouses, livestock facilities, and other outdoor settings.

One of the standout features of Desa heaters is their high-pressure design. This technology allows for rapid heating by forcing hot air into the surrounding area at a higher velocity compared to traditional heaters. This means that larger spaces can be heated more quickly and efficiently. With adjustable outlets, users can direct heat where it is needed most, further optimizing energy use and comfort.

These heaters utilize high-quality kerosene fuel, which offers a robust heating output while maintaining a clean burn. Kerosene is widely available and often more cost-effective than other heating fuels. The heaters are designed to efficiently burn kerosene, ensuring minimal emissions and environmental impact. This makes them suitable for both indoor and outdoor use when proper ventilation is provided.

Safety is a primary focus in the design of Desa high-pressure heaters. They are equipped with multiple safety features, including automatic shut-off mechanisms, which activate in the event of overheating or abnormal operation conditions. Additionally, robust construction ensures durability, allowing these heaters to withstand tough working conditions while providing reliable performance over time.

Ease of operation is another key characteristic of Desa heaters. Many models come with user-friendly controls that allow for straightforward adjustments of temperature settings and fan speeds. Portability is enhanced through built-in handles and lightweight designs, allowing users to transport the heaters with ease.

In conclusion, Desa Kerosene High Pressure Portable Forced Air Heaters offer effective heating solutions that combine high performance, safety, and convenience. With their advanced features, durability, and efficiency, they stand as a reliable choice for anyone needing substantial heat output in challenging environments. Whether for commercial, industrial, or agricultural use, these heaters provide an essential service by delivering warmth whenever and wherever it is most required.
