PRODUCT FEATURES This log set has been tested and approved to ANSI Z21.11.2-2013 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. DUAL FUEL CAPABILITY Your heater is equipped to operate on either propane or natural gas. The heater is shipped from the factory ready for connecting to propane.
PREPARING FOR INSTALLATION WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS Water vapor is a by-product of gas combustion. An unvented room heater produces approximately one (1) ounce (30 mL) of water for every 1,000 BTUs (.3 kw) of gas input per hour. An unvented room heater is recommended as a supplemental heater (a room) rather than a primary heat source (an entire house). In most supplemental heat applications, the water vapor does not create a problem.
PREPARING FOR INSTALLATION DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION Determining if You Have a Confined or Unconfined Space Use this worksheet 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 × Width × Height = cu. ft. (volume of space) Example: Space size 20 ft. (length) × 16 ft.(width) × 8 ft.
PREPARING FOR INSTALLATION WARNING: If the area in which the heater may be operated does not meet the required volume for indoor combustion air, combustion and ventilation air shall be provided 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 From Inside Building Fig 1 - Ventilation Air from Inside Building This fresh air would come from adjoining unconfined space.
INSTALLATION WARNING: Do not attempt to access or change the setting of the fuel selection means. Access to and adjustment of the fuel selection means must only be a performed by a qualified service person when connecting this appliance to a specified fuel supply at the time of installation. Change of the selector setting to other than the fuel type specified at the time of installation could damage this appliance and render it inoperable.

INSTALLATION 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. 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. Contact customer service for replacement parts.
INSTALLATION GAS SELECTION INSTRUCTIONS WARNING: This appliance can be used with propane or natural gas. It is shipped from the factory adjusted for use with propane. CAUTION: The knob to the gas selection means shall not be accessed or adjusted while the appliance is in operation. CAUTION: Two gas line installations at the same time are prohibited. The access plate to simple switching means shall not be opened while heater is in operation.
INSTALLATION CONNECTING TO GAS SUPPLY WARNING: A qualified service technician must connect heater to gas supply. Follow all local codes. CAUTION: Never connect heater directly to the gas supply. This heater requires an external regulator (not supplied). The external regulator between the gas supply and heater must be installed. Gas supplier provides external regulator for natural gas. WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas.
INSTALLATION CAUTION: Use pipe joint sealant that is resistant to gas (PROPANE or NG). We recommend that you install a sediment trap in a supply line. Locate sediment trap where it is within reach for cleaning and not likely to freeze. Install in the piping system between fuel supply and heater. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is installed incorrectly, heater may not run properly.
INSTALLATION CHECKING GAS CONNECTIONS WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all leaks immediately. WARNING: Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. If bubbles form, there may be a leak. Correct all leaks immediately. Pressure Testing Gas Supply Piping System Test Pressures In Excess Of 1/2 PSIG ( 3.5kPa ) 1.
INSTALLATION In compliance with ANSI Z21.60•CGA2.26 and National Fuel Gas Code, Section 6.
