www.camplux.com 1 5 WARNING Gasoline, as well as other flammable materials and liquids (adhesives, solvents, paint thinners etc.), and the vapors they produce are extremely dangerous. DO NOT handle, use or store gasoline or other flammable or combustible materials anywhere near or in the vicinity of a water heater or any other appliance. Be sure to read and follow the labels on the water heater, as well as the warnings printed in this manual.
www.camplux.com 6 DANGER Water temperature setting Safety and energy conservation are factors to be considered when selecting the water temperature setting. Water temperatures above 125°F can cause severe burns or death from scalding. The thermostat is adjusted to its lowest temperature position when shipped from the factory. Be sure to read and follow the warnings outlined on the label pictured below.
www.camplux.com 1 7 The temperature of the water at the outlet of the water heater can be regulated by setting the temperature on Remote Control . The remote control was set at 110°F before it was shipped from the factory. The illustration to the bottom left illustrates the Remote Control and how to adjust the water temperature.
www.camplux.com ● Propane or LP gas must be used with great caution. It is heavier than air and will collect first in lower areas making it hard to detect at nose level. ● Before attempting to light the water heater, make sure to look and smell for gas leaks. Use a soapy solution to check all gas fittings and connections. Bubbling at a connection indicates a leak that must be corrected. When smelling to detect a gas leak, be sure to sniff near the floor also.
www.camplux.com 1 9 Safety precautions Have the installer show you the location of the gas shut-off valve and how to shut it off if necessary. Turn off the manual shut-off valve if the water heater has been subjected to overheating, fire, flood, physical damage or if the gas supply fails to shut off. ● Read this manual entirely before installing or operating the water heater. ● Use this water heater only for its intended purpose as described in this Use and Care Manual.
www.camplux.com 10 Installing The Water Heater This water heater is for OUTDOOR installation ONLY! Make sure before installation that the gas type you will use is the same type on the data plate on the side of your water heater. The water heater should be installed by professionals from your local gas company. Please, don’t attempt installation by yourself. Improper installation may cause failure or dangerous conditions such as gas leaks or explosion.
www.camplux.com 11 1 Failure to properly install the water heater outdoors as outlined in this manual can result in unsafe operation. Hot and cold water lines should be insulated to conserve water and energy. DO NOT install water heater where subject to vibrations. DO NOT install the water heater in Recreational Vehicles, Mobile Homes, Boats and other Watercraft. DO NOT install the water heater near vents for heating or cooling. A minimum of 4 feet should be maintained.
www.camplux.com 12 Corrosive atmospheres The air in beauty shops, dry cleaning establishments, photo processing labs, and storage areas for liquid and powdered bleaches or swimming pool chemicals often contain such halogenated hydrocarbons. An air supply containing halogenated hydrocarbons may be safe to breathe, but when it passes through a gas flame corrosive elements are released that will shorten the life of any gas burning appliance.
www.camplux.
www.camplux.com 14 Water supply connections If a water heater is installed in a closed water supply system, such as one having a backflow preventer in the cold water supply line, means shall be provided to control thermal expansion. Contact the water supplier or local plumbing inspector on how to control this situation. Install a shutoff valve near the inlet of the water heater for service and draining purposes.
www.camplux.com 15 1 Hot Water Tap Drain Valve NOTICE: The pipes MUST be completely drainable. If the hot water faucets are located at a point higher than the water heater, place a drain valve at the lowest point (see illustration to the top). Gas supply WARNING: Do not attempt to convert this water heater for use with a different type of gas other than the type shown on the rating plate. Such conversion could result in hazardous operating conditions. Please have a professional connect the gas pipe.
www.camplux.com A sediment trap should be installed at the bottom of the gas line. Do not use excessive force (over 31.5 ft lbs.) in tightening the pipe, particularly if pipe-tape compound is used, as the unit may be damaged. The inlet gas pressure to the water heater must not exceed 10.5 “ w.c. for natural or 14” w.c. for LP gas. For purposes of input adjustment, the minimum inlet gas pressure (with main burner on) is shown on the water heater rating plate.
www.camplux.com 17 1 NOTICE: Manual operation of relief valves should be performed at least once a the relief valve and check the manual operation of the relief valve. You should take precaution to avoid contact with the hot water coming out of the relief valve and to prevent water damage. NOTICE: If the relief valve on the system discharges periodically, this may be due to thermal expansion in a closed water supply system.
www.camplux.com 18 Leak testing WARNING: Never use an open flame to test for gas leaks, as property damage, personal injury, or death could result. The water heater and its gas connections must be leak tested at normal operating pressures before it is placed in operation. ● Turn on the gas shut-off valve(s) to the water heater. ● Use a commercial leak detector or soapy water solution to test for leaks at all connections and fittings. Bubbles indicate a gas leak that must be corrected.
www.camplux.com 19 1 WARNING: Moisture in the flue gas will condense as it leaves the vent terminal. In cold weather this condensate can freeze on the exterior wall, under the eaves and on surrounding objects. Some discoloration to the exterior of the building is to be expected. However, improper location or installation can result in severe damage to the structure or exterior finish of the building. Code requirements are subject to change and may vary by location.
www.camplux.com 20 Remote Control Installation The following are considerations for determining the location of the remote control(s): ● DO NOT install any remote control outdoors. ● Place remote control(s) out of children’s reach. ● The remote control(s) can be installed in convenient locations such as the kitchen, laundry room, or utility room. ● The included remote control can be placed in a convenient location in a bathroom, however, AVOID areas where water may come into contact with the control(s).
