AIR FOR COMBUSTION AND VENTILATION WARNING: This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air. Read the following instructions to insure proper fresh air for this and other fuel-burning appliances in your home. Today’s homes are built more energy efficient than ever. New materials, increased insulation and new construction methods help reduce heat loss in homes.
AIR FOR COMBUSTION AND VENTILATION VENTILATION AIR Ventilation Air From Inside Building This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 2). You can also remove door into adjoining room (see option 3, Figure 2). Follow the National Fuel Gas Code, ANSI Z223.
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 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. CAUTION: Two gas line installations at the same time are prohibited. Back of Stove LP Gas Inlet Gas esté NG INLET GAS PRESSURE MAX 1/2 PSIG (3.
INSTALLATION 2. Apply thread sealant to the threads on a 3/8" NPT brass 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. Fitting supplied by installer, may vary. Use only the cap supplied on the regulator. Do not use an off the shelf pipe plug. This can damage the plunger.
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: 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. This heater requires an external regulator (not supplied).
INSTALLATION For propane/LP installations, apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves. The installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11" and 14" of w.c. If you do not reduce incoming gas pressure, heater regulator damage could occur.
INSTALLATION CHECKING GAS CONNECTIONS WARNING: Test all gas piping and connections 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.

OPERATION MODEL PCNSD25TA LIGHTING INSTRUCTIONS WARNING: You must operate this heater with the door closed and in the locked position. Make sure screen is installed before running heater. NOTICE: During initial operation of new heater, burning logs will give off a paper-burning smell. Orange flame will also be present. Open damper or window to vent smell. This will only last a few hours. 1. STOP! Read the safety information on page 17. 2. Make sure equipment shutoff valve is fully open. 3.
OPERATION THERMOSTAT CONTROL OPERATION 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 between Low (1) and HIGH (5).
OPERATION • If control knob does not pop up when released, contact a qualified service technician or gas supplier for repairs. 6. With control knob pressed in, push down and release ignitor button. This will light pilot. The pilot is attached to the rear of the burner. If needed, keep pressing ignitor button until pilot lights. Note: If pilot does not stay lit, refer to Troubleshooting, page 25. Also contact a qualified service technician or gas supplier for repairs.
OPERATION REMOTE CONTROL SYSTEM Programming the Remote and Receiver The remote and receiver must be “learned” to one another. To prepare the receiver box for learning, use a pen or small screwdriver to gently press and hold the learn button until you hear 3 series of beeps. 1. Place the slide switch on the receiver in the remote position (see Figure 20). 2. Turn control knob on the heater to the ON position. 3.
OPERATION Setting°F/°C Scale The factory setting for temperature is °F. To change this setting to°C, press the ON key and the OFF key on the remote control at the same time (see Figure 22, page 21). This will change from°F to °C. Follow this same procedure to change from°C back to°F. Manual Function To operate the system in the manual “MODE” do the following. ON OPERATION Press the ON key and the appliance flame will come on. During this time the LCD screen will show ON (see Figure 24).
INSPECTING BURNERS IMPORTANT: Owner’s should check pilot flame pattern and burner flame pattern often. Incorrect flame patterns indicate the need for cleaning (see Care and Maintenance, page 24 or service. WARNING: Only a qualified service person should service and repair heater. This includes maintenance requiring replacement or alteration of components. PILOT FLAME PATTERN Figure 26 shows a correct pilot flame pattern. Figure 27 shows an incorrect pilot flame pattern.
CARE AND MAINTENANCE WARNING: Turn off heater and let cool before servicing. CAUTION: You must keep control areas, burner, and circulating air passageways of heater clean. Inspect these areas of heater before each use. Have heater inspected yearly by a qualified service technician. Heater may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc. WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage.
CARE AND MAINTENANCE ODS/PILOT Use a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean. A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about 2" from where the pilot flame comes out of the pilot assembly (see Figure 31). With the unit off, lightly blow air through the air inlet hole. You may blow through a drinking straw if compressed air is not available.
TROUBLESHOOTING Problem Possible Cause Corrective Action Using natural gas and pilot will not light. Inlet pressure exceeds 9.5" WC. Bypass pressure switch. See instructions below.
