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 ensure proper fresh air for this and other fuel-burning appliances in your home.
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. (ceiling height) =2560 cu. ft.
WARNING: If the area in which the heater may be operated is smaller than that defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54. Air for Combustion and Ventilation, or applicable local codes.
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.
FASTENING HEATER TO WALL Mounting Bracket The mounting bracket is located on back panel of heater (see Figure 5). It has been taped there for shipping. Remove mounting bracket from back panel. Removing Front Panel of Heater 1. Remove two screws near bottom corners of lower front panel . 2. Pull bottom of lower front panel forward, then down (see Figure 6). Methods For Attaching Mounting Bracket To Wall Use only the last hole on each end of mounting bracket to attach bracket to wall.
Attaching to Wall Anchor Method For attaching mounting bracket to hollow walls (wall areas between studs) or solid walls (concrete or masonry): 1. Drill holes at marked locations using 5/16-inch drill bit. For solid walls (concrete or masonry), drill at least 1 inch deep. 2. Fold wall anchor as shown in Figure 8. 3. Insert wall anchor (wings first) into hole. Tap anchor flush to wall. 4. Figure 8 - Folding Anchor For thin walls (1/2 inch or less), insert red key into wall anchor.
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-inch NPT (National Pipe Thread) inlet connection to the pressure regulator. WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas. WARNING: Do not over-tighten gas connections. CAUTION: Use only new, black iron or steel pipe. Internally tinned copper tubing may be used in certain areas.
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 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 13.
Figure 14 Figure 15 Figure 16 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 mixture of liquid soap and water to all joints. If bubbles form, there is a leak. Correct all leaks at once. Pressure Testing Gas Supply Piping System Test Pressures In Excess Of 1/2 PSIG (3.5kPa) 1.
