OPERATION

WARNING: Follow the mini- mum fresh, outside air ventila- tion requirements. If proper fresh, outside air ventilation is not pro- vided, carbon monoxide poison- ing can occur. Provide proper fresh, outside air ventilation be- fore running heater.

WARNING: Review and under- stand the warnings in the Safety Information section, page 2. They are needed to safely operate this heater. Follow all local codes when using this heater.

TO START HEATER

1.Follow all installation, ventilation and safety information.

2.Locate heater on stable and level surface. Make sure strong drafts do not blow into front or rear of heater.

3.Make sure the control knob is in the OFF position.

4.Plug power cord of heater into a three-prong, grounded extension cord. Extension cord must be at least six feet long, UL/CSA listed, and of a proper size.

Extension Cord Size Requirement

Up to 100 feet long, use 16 AWG rated cord.

101 to 200 feet long, use 14 AWG rated cord.

5.Plug extension cord into a 120 volt/60 hertz, 3-hole, grounded outlet. Motor will start. Fan will turn, forcing air out front of heater.

6.Open propane supply valve on propane tank(s) slowly. Note: If not opened slowly, excess-flow check valve on propane tank will stop gas flow. You may hear a click from the excess-flow check valve closing. If this happens, reset the excess-flow check valve by closing propane supply valve and open again slowly.

7.Press and hold in control knob. Turn counterclockwise to the LOW position. Heater should ignite within a few seconds.

Note: If heater fails to ignite, hose may have air in it. If so, keep control knob pressed and wait 20 seconds. Release automatic control valve button and wait 20 seconds for unburned fuel to exit heater. Repeat step 7.

8.After heater ignites, wait 30 seconds. This activates the automatic control system. Release the control knob.

9.When burner remains lit, set heater at the desired heat level by turning the control valve counterclockwise. If burner goes out, turn off gas. Turn control knob fully clockwise to the lowest position. Check fuel supply. If adequate fuel is available, restart heater beginning at step 1.

TO STOP HEATER

1.Tightly close propane supply valve on propane tank(s).

2.Wait a few seconds. Heater will burn gas left in supply hoses.

3.Turn control knob to the OFF position.

4.Unplug heater.

STORAGE

CAUTION: Disconnect heater from propane supply tank(s).

1.Store propane tank(s) in safe manner. See Chapter 5 of Standard for Storage and Handling of Liquefied Petroleum Gases, ANSI/NFPA 58 and the Propane Installation Code CAN/CGA B149.2. Follow all local codes. Always store propane tanks outdoors.

2.Place plastic cover caps over brass fittings on inlet connector and hose/ regulator assembly.

3.Store in dry, clean, and safe place. Do not store hose/regulator assembly inside heater combustion chamber.

4.When taking heater out of storage, always check inside of heater. Insects and small animals may place foreign objects in heater. Keep inside of heater free from combustible and foreign objects.

MAINTENANCE

WARNINGS

Never service heater while it is plugged in, connected to pro- pane supply, operating, or hot. Severe burns and electrical shock can occur.

Keep heater clear and free from combustible materials, gaso- line, and other flammable va- pors and liquids.

The construction of Desa propane heaters is designed for durability. Made from high-quality materials, these heaters can withstand the rigors of outdoor use and resist corrosion and impacts. The stainless steel burners are designed for longevity and optimal performance, providing consistent heat generation over extended periods.

In terms of technology, most Desa propane heaters include features such as a thermostat for temperature regulation and a fan-forced design that distributes heat evenly across larger areas. This ensures that workers are kept comfortable, which can boost productivity and morale on the job site.

By choosing Desa propane construction heaters, contractors invest in a versatile and efficient heating solution that meets the demanding needs of construction projects. With their combination of portability, safety features, and durable design, Desa heaters stand out as a reliable choice for anyone looking to maintain a productive work environment in challenging weather conditions.
