SAFETY PRECAUTIONS
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 propane gas.
4.Use only VAPOR WITHDRAWAL propane supply. If there is any question about vapor withdrawal, ask your propane dealer.
5.Mount the propane cylinders vertically (shutoff valve up). Secure them from falling or being knocked over and protect them from damage.
6.Locate propane containers at least (USA) 7 ft. (2.13m), (Canada) 10 ft. (3m) from the heater and do not direct exhaust toward containers.
7.IMPORTANT Use only the hose and regulator assembly provided with the heater. Match the color stripe on the hangtag attached to the hose assembly with the color on the label located near the propane inlet fitting on the heater. Inspect hose assembly before each use of the heater. If there is excessive abrasion or wear, or hose is cut, replace with hose assembly listed on parts list before using heater.
8.For indoor use only. Area must be well ventilated. Figure 1. (also see "Operating Precautions").
9.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 and Propane Sheet for additional information about detecting propane 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 (USA) and CSA C22.1 Canadian Electrical Code, Part 1 (Canada).
