Introduction – 5IntroductionPlease read our instructions before you install and use your heater. This will help you obtain the full value from this heater. It couldhelp you avoid needless service costs, if the answer to the problem is found within this instruction manual. If the answer is not found,call our Customer Service Department at (909) 825-0993 before returning the heater to your supplier.Today's homes are built more energy efficient than ever. New materials, increased insulation and new construction methods helpreduce heat loss in homes. Homeowners weather strip and caulk around windows and doors to keep the cold air out and the warm airin. During heating months, homeowners want their homes as airtight as possible. While it is good to make your home energy efficient,your home needs to breathe. Fresh air must enter your home. All fuel-burning appliances need fresh air for proper combustion andventilation.Basic DescriptionUnvented heaters are shipped ready to install. No electric poweris needed for the heater except when the optional accessoryblower is used. Then, a standard three prong receptacle(electrical outlet) is needed near the heater.Always consult your local heating or plumbing inspector, buildingdepartment or gas utility company regarding regulations, codes orordinances which apply to the installation of an unvented heater.The heater contains a single, multi-slot gas burner.Combustion air is drawn to the heater from the room in which it isinstalled. It must receive enough air to enable it to operateproperly. See page 7 of this instruction manual for moreinformation.Convection causes room air to circulate from the floor upwardalong the front, back and sides of the heater, and then back to theroom.The heater cabinet is built of heavy-gauge steel treated forcorrosion resistance and has an enamel paint finish. The heatercontrols are located on the top of the cabinet. All models areequipped with AGA/CGA listed gas valves and pilots.Piezo Ignition SystemThis unit has a piezo igniter. This system requires no matches,batteries, or other sources to light the heater.Thermostatic Heat ControlThermostat models have a thermostat sensing bulb and a controlvalve. This results in the greatest heat comfort. This can alsoresult in lower gas bills.Safety DeviceThis unit has a pilot with an Oxygen Depletion Sensor shutoffsystem (ODS). The ODS/pilot is a required feature for unventedroom heaters. The ODS/pilot shuts off the heater if there is notenough fresh air. When the normal oxygen content(approximately 21 %) is reduced to 18%, the pilot and mainburner will turn off and cannot be relighted. When the pilot flameis extinguished by wind or interruption of gas supply, it will alsoturn off. Relighting is possible in this condition.Basic Materials NeededPipe and fittings to make connections to heater.Black iron gas pipe and fittings - 1/2".Pipe Joint Compound resistant to L.P. gases.Electrical supplies only required if accessory blower is beinginstalled.Electrical wiring supplies as needed.Minimum wire size is #14 gauge copper.Basic Tools NeededPipe WrenchesScrewdriver6 ft. folding rule or tapeLevelPipe cutting and threading toolsGloves and safety glassesHelpful Installation InformationThe following booklets will help you in making the installation:ANSI/NFPA 70, or current edition “National Electrical Code”.
