OPERATING PRECAUTIONS | SAFETY PRECAUTIONS |
This is a natural gas,
If natural gas leaks from a connection or fitting, it mixes with the surrounding air, forming a potentially explosive mixture. Obviously, gas leaks should be avoided, so set up the gas supply with utmost care. Read enclosed Odor Fade Sheet for additional information about detecting gas leaks. Leak check new connections or reconnections with a soap and water solution and follow all connections instructions herein.
This heater was designed and certified for use as a construction heater in accordance with ANSI Standard Z83.7/ CGA

So, be sure to follow advice about ventilation in these operating instructions.
Forced Air means that a blower or fan pushes the air through the heater. Proper combustion depends upon this air flow; therefore, the heater must not be revised, modified or operated with parts removed or missing. Likewise, safety systems must not be circumvented or modified in order to operate the heater.
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. (also see "Operating Precautions").
8.If at any time gas odor is detected, IMMEDIATELY DISCONTINUE operation until the source of gas has been located and corrected. Read enclosed Odor Fade Sheet for additional information about detecting gas leaks.
10.Install the heater such that is is not directly exposed to water spray, rain and/or dripping water.
11.Maintain minimum clearance from normal combustible material (like paper). Figure 2.
12.Due to the high surface and exhaust temperatures, adults
and children must observe clearances to avoid burns or clothing ignition.
13.Operate only on a stable, level surface.
14.Do not use with ductwork. Do not restrict inlet or exit.
15.Use only the electrical power specified. The electrical connection and grounding must comply with National Electrical Code - ANSI/NFPA 70.
16.Use only a properly grounded
17.Do not move, handle or service while hot or burning.
18.Use only in accordance with local codes.
