PRODUCT FEATURES This log set has been tested and approved to ANSI Z21.11.2 standard for Unvented Heaters and can be operated with the flue damper closed. State and local codes in some areas prohibit the use of vent-free heaters. SAFETY PILOT THERMOSTAT HEAT CONTROL This heater has a pilot with an Oxygen Depletion Sensing (ODS) safety shutoff system. The ODS/pilot shuts off the heater if there is not enough fresh air.
QUALIFIED INSTALLING AGENCY Only a qualified agency should install and replace gas piping, gas utilization equipment or accessories, and repair and equipment servicing.
AIR FOR COMBUSTION AND VENTILATION WARNING: If the area in which the heater may be operated is smaller than that defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54, the International Fuel Gas Code, or applicable local codes. VENTILATION AIR Ventilation Air From Inside Building This fresh air would come from an adjoining unconfined space.
INSTALLATION NOTICE: This heater is intended for use as supplemental heat. Use this heater along with your primary heating system. Do not install this heater as your primary heat source. If you have a central heating system, you may run system’s circulating blower while using heater. This will help circulate the heat throughout the house. In the event of a power outage, you can use this heater as your primary heat source. WARNING: A qualified service person must install heater. Follow all local codes.
INSTALLATION IMPORTANT: Vent-free heaters add moisture to the air. Although this is beneficial, installing heater in rooms without enough ventilation air may cause mildew to form too much moisture. See Air for Combustion and Ventilation, pages 6 and 7. Before beginning assembly or operation of the product, make sure all parts are present. Compare parts with package contents list. If any part is missing or damaged, do not attempt to assemble, install or operate the product.
INSTALLATION NOTICE: This heater may be used as a vented product. If so, you must always operate log set with chimney flue damper open. If running log set with damper open, noncombustible material above fireplace opening is not needed. Go to Installing Damper Clamp Accessory for Vented Operation, page 11. If Using Mantel You must have noncombustible material(s) above the fireplace opening. Noncombustible materials (such as slate, marble, tile, etc.) must be at least 1/2" thick.
INSTALLATION FLOOR CLEARANCES A. If installing appliance on the floor level, you must maintain the minimum distance of 14" to combustibles (see Figure 8). 14" Min. B. If combustible materials are less than 14" to the fireplace, you must install appliance at least 5" above the combustible flooring (see Figure 9). Combustible Material Hearth 5" Min.
INSTALLATION GAS SELECTION This appliance is factory preset for propane/LP gas. No changes are required for connecting to propane/LP. Only a qualified installer or service technician can perform gas selection and connecting to gas supply. Insert Gas Fitting for Propane/LP Gas Blue Propane/ LP Gas Plunger Underneath Dust Cover CAUTION: Two gas line installations at the same time are prohibited.
INSTALLATION 2. Apply thread sealant to the threads on the connection fitting. While pushing in, rotate the fitting clockwise until the threads engage the regulator. After the fitting has been hand tightened into the regulator use a wrench to complete tightening of the fitting. Install additional fitting to connect to the house supply. Use only the cap supplied on the regulator. Do not use an off the shelf pipe plug. This can damage the plunger.
INSTALLATION BATTERY INSTRUCTIONS CAUTION: Do not dispose of batteries in fire, batteries may explode or leak. • Batteries are included. • Remove batteries when depleted. • Be sure to observe proper polarity (+/-) when installing or replacing the batteries. Damage due to improper battery installation may void the warranty on the product. • For long periods of non-operation, remove batteries from all components for safety. Unscrew ignitor cap and install a AAA battery with the + pointing out. Replace cap.
INSTALLATION CONNECTING TO GAS SUPPLY WARNING: A qualified service technician must connect heater to gas supply. Follow all local codes. WARNING: This appliance requires a 3/8" NPT (National Pipe Thread) inlet connection to the pressure regulator. WARNING: Do not overtighten gas connections. WARNING: For natural gas, Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas. CAUTION: For propane/LP gas, never connect heater directly to the gas supply.
INSTALLATION Typical Inlet Pipe Diameters Use 1/2" black iron pipe or greater. Installation must include an equipment shutoff valve, union, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Figure 16). IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance. For propane/LP installations, apply pipe joint sealant lightly to male threads.
INSTALLATION CHECKING GAS CONNECTIONS WARNING: Test all gas piping and connections, internal and external to unit, for leaks after installing or servicing. Correct all leaks at once. WARNING: Never use an open flame to check for a leak. Apply a noncorrosive leak detection fluid to all joints. If bubbles form, there is a leak. Correct all leaks at once. PRESSURE TESTING GAS SUPPLY PIPING SYSTEM Test Pressures In Excess Of 1/2 PSIG (3.5 kPa) 1.
INSTALLATION INSTALLING LOGS WARNING: Failure to position the parts in accordance with these diagrams or failure to use only parts specifically approved with this heater may result in property damage or personal injury. CAUTION: After installation and periodically thereafter, check to ensure that no yellow flame comes in contact with any log. With the heater set to High, check to see if yellow flames contact any log. If so, reposition logs according to the log installation instructions in this manual.
OPERATION Avoid any drafts that alter burner flame patterns. Do not allow fans to blow directly into the fireplace. Do not place a blower inside the burn area of the firebox. Ceiling fans may create drafts that alter flame patterns. Sooting and improper burning will result. During manufacturing, fabricating and shipping, various components of this appliance are treated with certain oils, films or bonding agents.
OPERATION 5. Push in control knob slightly and turn counterclockwise to the PILOT position. Press in control knob for five (5) seconds. Note: The first time that the heater is operated after connecting the gas supply, the control knob should be pressed for about thirty (30) seconds. This will allow air to bleed from the gas system. If pilot does not stay lit, refer to Troubleshooting, pages 24 though 27. Also contact a qualified service technician or gas supplier for repairs.
OPERATION THERMOSTATIC CONTROL OPERATION Models PCNSD18T and PCNSD24TD Only The thermostatic control used on this model differs from standard thermostats. Standard thermostats simply turn the burner on and off. The thermostat used on this heater senses the room temperature. At times the room may exceed the set temperature. If so, the burner will shut off. The burner will cycle back on when room temperature drops below the set temperature. The control knob can be set to any comfort level.
Approx. 3"-6" Above Top of Logs INSPECTING BURNERS BURNER FLAME PATTERN Figure 28 shows a correct burner flame pattern. Figure 29 shows an incorrect burner flame pattern. If burner flame pattern is incorrect then: • turn heater off (see To Turn Off Gas to Appliance, page 20). • see Troubleshooting pages 24 through 27. More Than 8" Above Top of Logs Approx.
CARE AND MAINTENANCE BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE We recommend that you clean the unit every 2,500 hours of operation or every three months. We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recommend using compressed air no greater than 30 PSl. Your local computer store, hardware store, or home center may carry compressed air in a can. You can use a vacuum cleaner in the blow position.
