General Preparation LOCAL CODES Install and use the heater with care. Follow all local codes. The installation must conform with local codes or, In the absence of local codes, with the latest edition of The National Fuel Gas Code, ANS Z223.1/NFPA 54*. *Available from: American National Standard Institute, Inc. 1430 Broadway New York, NY 10018 National Fire Protection Association, Inc. 1 Batterymarch Park Quincy, MA 02269-9101 This heater is designed for vent-free operation.
Preparing for Installation WATER VAPOR IS A BY-PRODUCT OF UNVENTED ROOM HEATERS Gas combustion creates water vapor as a by-product. Unvented room heaters create about one (1) ounce (30 ml) of water for every 1,000 BTUs (0.3 kW) of gas input per hour. An unvented room heater is recommended as a supplemental heat source for a single room rather than as a primary heat source for an entire house. The water vapor does not typically create a problem.
Preparing for Installation (cont.) DETERMINING FRESH-AIR FLOW FOR THE HEATER LOCATION Determining if You Have a Confined or Unconfined Space: Use the below information to determine if you have a confined or unconfined space. Your space includes the room in which you will install the heater plus any other rooms that are directly connected and have doorless passageways or ventilation grills between the rooms. 1. Determine the volume of the space. Length × Width × Height = cu. ft.
Preparing for Installation (cont.) If the area in where the heater operates does not meet the required volume for indoor combustion air, you must provide combustion and ventilation air by one of the methods described in the NATIONAL FUEL GAS CODE, ANS Z223.1/NFPA 54, the INTERNATIONAL FUEL GAS CODE, or applicable local codes. WARNING VENTILATION AIR FROM INSIDE A BUILDING Fresh air comes from a connected unconfined space.
Installation NOTICE: This heater is intended to be used as a supplemental heating source. Use this heater along with your primary heating system. This heater must not be used as a primary heat source. If you have a central heating system, you may run that system’s circulating blower while using this heater. This helps to circulate the heat around your house. WARNING A qualified technician must install the heater. Follow all local codes.

HEATER CLEARANCES For convenience and efficiency, install the heater with these points in mind: • Provide easy access for operation, inspection and service. • Install the heater in the coldest part of the room. If this heater is installed directly on carpeting, tile, or other combustible material, other than wood flooring, the heater must be installed on a metal or wood panel that extends the heater’s full width and depth. If you install the heater in a home garage, a.
Installation (cont.) INSTALLING THE FAN (OPTIONAL) Electrical grounding instructions: This appliance is equipped with a three-prong (grounding) plug for your protection against shock hazard and should be plugged directly into a properly grounded threeprong receptacle (See Fig. 4). WARNING 1. Disconnect the wall mounted heater from the gas supply and remove it from the wall before installing the fan accessory. Contact a qualified service person to do this. 2.
Installation (cont.) POSITIONING THE HEATER This heater can be mounted on a wall or on a floor by using the Support Legs included with select models. For convenience and efficiency, install the heater as follows: • In a location with easy access for operation, inspection, and service. • In the coldest part of the room. • A minimum of 3' (36") away from furniture and draperies. Fig.
Installation (cont.) WALL MOUNTING WARNING ELECTRICAL, PLUMBING, OR GAS LINES MAY BE IN WALL. Before cutting, drilling, or hammering, verify their location. If needed, contact your electrician, plumber, or service person. 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.
Installation (cont.) Attaching to Expansion Bracket Method: NOTE: This method is for attaching the mounting bracket to solid walls (concrete or masonry) or to hollow walls (wall areas between studs). 1. Drill holes at the marked locations using a 5/16" drill bit. For solid walls (concrete or masonry), drill at least 1" deep. 2. Insert the wall expansion pipes into each hole as shown in Fig. 12 and 13. Tap the expansion pipes flush to the wall. 3. Place the mounting bracket onto the wall.
Installation (cont.) CONNECTING TO A GAS SUPPLY WARNING A qualified service technician must connect heater to gas supply. Follow all local codes. WARNING Never connect the heater to private/non-utility gas wells (commonly known as wellhead gas). CAUTION Never connect the 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.
Installation (cont.) 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, which traps moisture and contaminants. The sediment trap should be located within reach for cleaning and where it is not likely to freeze. Install it in the piping system between the fuel supply and heater. This keeps contaminants from getting into the heater controls.
Installation (cont.) CHECKING GAS CONNECTIONS WARNING After installing or servicing the heater, test all gas piping and connections for leaks. Immediately correct all leaks. WARNING Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints—bubbles may indicate a leak. Immediately correct all leaks. Pressure Testing Gas Supply Piping System Test Pressures in Excess Of 1/2 PSIG (3.5 kPa): 1.
