OPERATING PRECAUTIONS SAFETY PRECAUTIONS

This is a natural gas, direct-fired, radiant heater. It's intended use is primarily temporary heating of buildings under construction, alteration or repair.

When the heater is to be operated in the presence of other people the user is responsible for properly acquainting those present with the safety precautions and instructions, and of the hazards involved.

1.Check the heater thoroughly for damage. DO NOT operate a damaged heater.

2.DO NOT modify the heater or operate a heater which has been modified from its original condition.

3.Use only natural gas.

4.Provide at least 5" W.C. but not over 1/2 psig to the heater inlet (regulator inlet).

5.Use an appropriate hose or flexible connector not over 10 ft. (3.05m) in length.

6.Operate the heater only with the 4" W.C.regulator provided by the factory.

7.For indoor use only. Area must be well ventilated. (Figure 1).

8.If at any time gas odor is detected, IMMEDIATELY DISCONTINUE operation until the source of gas has been located and corrected. (See Odor Fade Warnings on page 4.)

9.Install the heater such that is is not directly exposed to water spray, rain and/or dripping water.

10.Maintain minimum clearance from normal combustible material (like paper). (Figure 2). Locate 10 ft. from canvas tarpaulins or similar coverings and secure them to prevent flapping or movement due to wind action.

11.Due to the high surface and exhaust temperatures, adults and children must observe clearances to avoid burns or clothing ignition.

12.Operate only on a stable, level surface.

13.Do not move, handle or service while hot or burning.

14.Use only in accordance with local codes or, in the absence of local codes, with the Standard for the Storage and Handling of Liquefied Petroleum Gases ANSI/NFPA 58.
