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 DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION Determining if You Have a Confined or Unconfined Space Use this work sheet to determine if you have 4. Compare the maximum Btu/Hr the space a confined or unconfined space. can support with the actual amount of Btu/ Hr used.
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. The access plate to the simple switching means shall not be opened while the heater is in operation.
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 PCSD25T 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 above. 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 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 26 though 28. Also contact a qualified service technician or gas supplier for repairs. Until repairs are made, light pilot with match.
OPERATION REMOTE CONTROL SYSTEM AA AA AA AA Install Batteries Batteries are required in both the Remote Control (Transmitter) (2 AAA size) and Receiver (4 AA size) (see Figure 20). Note: Be sure batteries are placed correctly. Reversing the batteries can cause damage to the receiver and remote. Replace all batteries on a yearly basis or sooner. F N AR LE TE OF MO ON RE A AA Programming the Remote and Receiver The remote and receiver must be “learned” to one another. 1.
OPERATION LCD Liquid Crystal Display 1. DISPLAY Indicates CURRENT room temperature. 2. °F or °C Indicates degrees Fahrenheit or Celsius. 3. FLAME Indicates burner/valve in operation. 4.

OFF OPERATION Press the OFF key and the appliance flame will shut off. During this time the LCD screen will show OF (see Figure 25).
OPERATION REMOTE CONTROL The Thermo Feature on the transmitter operates the appliance whenever the ROOM TEMPERATURE varies a certain number of degrees from the SET TEMPERATURE. This variation is called the “swing” or temperature differential. The normal operating cycle of an appliance may be 4 times per hour depending on how well the room or home is insulated from the cold or drafts. The factory setting for the “swing number” is 2.
