PRODUCT FEATURES OPERATION This heater is clean burning. It requires no outside venting. There is no heat loss out a vent or up a chimney. Heat is generated by realistic, dancing yellow flames. This heater is designed for vent-free operation. State and local codes in some areas prohibit the use of vent-free heaters. SAFETY PILOT This heater has a pilot with an Oxygen Depletion Sensing (ODS) safety shutoff system. The ODS/pilot is a required feature for vent-free room heaters.
AIR FOR COMBUSTION AND VENTILATION Continued 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 a confined or unconfined space. Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways or ventilation grills between the rooms. 1. Determine the volume of the space (length x width x height). Length x Width x Height = ________cu. ft.
AIR FOR COMBUSTION AND VENTILATION Continued 12" Ventilation Grills Into Adjoining Room, Option 1 Ventilation Grills Into Adjoining Room, Option 2 Or Remove Door into Adjoining Room, Option 3 12" Figure 2 - Ventilation Air from Inside Building Ventilation Air From Outdoors Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor.
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 CONNECTING TO GAS SUPPLY Continued WARNING: This appliance requires a 1/2" NPT (National Pipe Thread) inlet connection to the pressure regulator. Ceiling 48" Minimum Side Wall 12" Minimum 12" Minimum Side Wall Front View Back Wall 6" Minimum 12 " Minimum 12 " Minimum Side Wall Side Wall WARNING: A qualified service person must connect heater to gas supply. Follow all local codes. CAUTION: Never connect propane/LP heater directly to the propane/LP supply.
INSTALLATION Continued For propane/LP units, 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 inches of water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 7. Pointing the vent down protects it from freezing rain or sleet.
INSTALLATION Continued 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. Bubbles forming show a leak. Correct all leaks at once. CAUTION: Make sure external regulator has been installed between propane/LP supply and propane/LP heater.
INSTALLATION INSTALLING LOG SET Continued Equipment Shutoff Valve Gas Meter Control Valve Location Figure 11 - Checking Gas Joints on Natural Gas Unit INSTALLING ROD AND SCREEN 1. Insert rod through small rings located at top of screen (see Figure 12). 2. From back of stove, insert rod into hole located inside right front of stove as shown in Figure 13. 3. Slip left side of rod down into slot on inside left front of stove (see Figure 13). 1. Set one-piece log on heater base as shown in Figure 14.
OPERATING HEATER FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance has a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly. B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
OPERATING HEATER Continued TO TURN OFF GAS TO APPLIANCE Note: The correct pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color. Thermocouple Shutting Off Heater Turn control knob clockwise OFF position. Pilot Burner to the Shutting Off Burners Only (pilot stays lit) Turn control knob clockwise to the PILOT position.
CLEANING AND MAINTENANCE Burner Tube Continued BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE The primary air inlet holes allow the proper amount of air to mix with the gas. This provides a clean burning flame. Keep these holes clear of dust, dirt, lint and pet hair. Clean these air inlet holes prior to each heating season. Blocked air holes will create soot. We recommend that you clean the unit every three months during operation and have heater inspected yearly by a qualified service person.
TROUBLESHOOTING WARNING: Turn off heater and let cool before servicing. Only a qualified service person should service and repair heater. CAUTION: Never use a wire, needle or similar object to clean ODS/pilot. This can damage ODS/pilot unit. Note: All troubleshooting items are listed in order of operation. OBSERVED PROBLEM POSSIBLE CAUSE When ignitor button is pressed, 1. Ignitor electrode not conthere is no spark at ODS/pilot nected to ignitor cable 2. Ignitor cable pinched or wet 3. 4. 5. 6.
TROUBLESHOOTING Continued OBSERVED PROBLEM POSSIBLE CAUSE Burner does not light after ODS/ 1. Burner orifice clogged pilot is lit 2. Inlet gas pressure is too low Delayed ignition burner 1. Manifold pressure is too low 2. Burner orifice clogged REMEDY 1. Clean burner (see Cleaning and Maintenance, page 14) or replace burner orifice 2. Contact local natural or propane/LP gas company 1. Contact local natural or propane/LP gas company 2.
TROUBLESHOOTING Continued WARNING: If you smell gas • Shut off gas supply. • Do not try to light any appliance. • Do not touch any electrical switch; do not use any phone in your building. • Immediately call your gas supplier from a neighbor’s phone.
