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 (0.3 Kw) of gas input per hour. An unvented room heater is intended as a supplemental heater rather than a primary heat source. In most supplemental heat applications, the water vapor does not create a problem. In most applications, the water vapor enhances the low humidity atmosphere experienced during cold weather. The following steps will help ensure that water vapor does not become a problem: 1. Be sure the heater is the proper size for the application, including adequate combustion air and
circulation air. 2. If there is high humidity, a dehumidifier may be used to help lower the water vapor content
of the air. 3. Do not use an unvented room heater as the primary heat source.

PREPARING FOR INSTALLATION
AIR FOR COMBUSTION AND VENTILATION
CAUTION: This heater shall not be installed in a room or space unless the required volume of indoor combustion air is provided by the method described in the National Fuel Gas Code, ANS Z223.1/NFPA54, the International Fuel Gas Code, or applicable local codes.
PRODUCING ADEQUATE VENTILATION All spaces in homes fall into one of the three following ventilation classifications: 1. Unusually Tight Construction 2. Unconfined Space 3. Confined Space The information on pages 7 through 9 will help you classify your space and provide adequate ventilation.
Confined and Unconfined Space A confined space as a space whose volume is less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate input rating of all appliances installed in that space and an unconfining space as a space whose volume is not less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms connecting directly with the space in which the appliances are installed*, through openings not furnished with doors, are considered a part of the unconfined space. This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air.

• Adjoining rooms are connecting only if there are doorless passageways or ventilation grills between them.
  Unusually Tight Construction The air that leaks around doors and windows may provide enough fresh air for combustion and ventilation. However, in buildings of unusually tight construction, you must provide additional fresh air. Unusually tight construction is defined as construction where: a) walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder
  with a rating of one perm (6×10-11kg per pa-sec-m2) or less with openings gasketed or sealed and b) weather stripping has been added on windows that can be opened and on doors and c) caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.
  If your home meets all of the three criteria above, you must provide additional fresh air. See “Ventilation Air From Outdoors” (page 9). If your home does not meet all of the three criteria above, proceed to “Determining Fresh-Air Flow For Heater Location”.
  7

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. (ceiling height) = 2560 cu. ft. (volume of space)
If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of the space. 2. Divide the space volume by 50 cu. ft. to determine the maximum BTU/hr the space can support.
_ (volume of space) ÷ 50 cu. ft.= (Maximum BTU/hr the space can support) Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum BTU/hr the space can support) 3. Add the BTU/hr of all fuel burning appliances in the space. Vent-free heater ___ BTU/hr Gas water heater ____BTU/hr Gas furnace _____BTU/hr Vented gas heater ____BTU/hr Example: Gas heater logs __BTU/hr Gas water heater 30,000 BTU/hr Other gas appliances+ BTU/hr Vent-free heater + 26,000 BTU/hr Total = BTU/hr Total = 56,000 BTU/hr *Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors. 4. Compare the maximum BTU/hr the space can support with the actual amount of BTU/hr used. BTU/hr (maximum the space can support) BTU/hr (actual amount of BTU/hr used). Example : 51,200 BTU/hr (maximum the space can support) 56,000 BTU/hr (actual amount of BTU/hr used) The space in the above example is a confined space because the actual BTU/hr used is more than the maximum BTU/hr the space can support. You must provide additional fresh air. Your options are as follows:
a) Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoining room or add ventilation grills between rooms. See “Ventilation Air From Inside Building,” page 9. b) Vent room directly to the outdoors. See “Ventilation Air From Outdoors”, page 9. c) Install a lower BTU/hr heater if lower BTU/hr size makes room unconfined. If the actual BTU/hr used is less than the maximum BTU/hr the space can support, the space is an unconfined space. You will need no additional fresh air ventilation.
8

PREPARING FOR INSTALLATION
Ventilation Air From Inside Building
This fresh air would come from adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12 in. of the wall connecting the two spaces (see options 1 and 2, Fig. 1). You can also remove door into adjoining room (see option 3, Fig. 1). Follow the National Fuel Gas Code NFPA 54/ANS Z223.1. Air for Combustion and Ventilation for required size of ventilation grills or ducts.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or duct. You must provide two permanent openings: one within 12 in. of the ceiling and one within 12 in. of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Follow the National Fuel Gas Code NFPA 54/ANS Z223.1. Air for Combustion and Ventilation for required size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a thermostat-controlled power vent. Heated air entering the attic will activate the power vent. Rework worksheet, adding the space of the adjoining unconfined space. The combined spaces must have enough fresh air to supply all appliances in both spaces.

INSTALLATION Methods For Attaching Mounting Bracket To Wall

Use only the last hole on each end of mounting bracket to attach bracket to wall. Attach mounting bracket to a wall only in one of two ways:

1. Attaching to wall stud: This method provides the strongest hold. Insert wood screws (ST.8*45-16) through mounting bracket and into wall studs.

2. Attaching to expansion bracket: This method allows you to attach mounting bracket to hollow walls (wall areas between studs) or to solid walls (concrete or masonry).

Decide which method better suits your needs. Either method will provide a secure hold for the mounting bracket.

Marking Screw Locations 1. Tape mounting bracket to wall where heater
will be located. Make sure mounting bracket is level.
2. Mark screw locations on wall (See Fig. 16). Note: Mark only last hole on each end of mounting bracket. Insert (2) wood screws (ST.8*45-16) total through these holes only.

INSTALLATION
CONNECTING TO GAS SUPPLY
WARNING: A qualified service technician must connect heater to gas supply. Follow all local codes.
IMPORTANT: This appliance requires a 3/8-inch NPT (National Pipe Thread) inlet connection to the pressure regulator. Never connect the heater to private (non-utility) gas wells, commonly known as wellhead gas.
WARNING: Do not overtighten gas connections.
CAUTION: Use only new, black iron or steel pipe. Internally tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2-in. diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.
CAUTION: Two gas line installations at the same time are prohibited. The access plate to the switching means shall not be opened while the heater is in operation.
CAUTION: Check your gas line pressure before connecting heater to gas line. Gas line pressure must be a minimum 6” WC for NG & 11″ WC for LP with a max pressure of 14” WC for NG & 14″ WC for LP. If gas line pressure is higher, regulator damage could occur.
CAUTION: Never connect heater directly to an LP supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and gas supply.
CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting into gas piping and/or fittings.
CAUTION: Use pipe joint sealant that is resistant to gas (Propane or Natural Gas).
Typical Inlet Pipe Diameters Use 3/8-inch black iron pipe or greater. Installation must include an equipment shutoff valve, union, and plugged 1/8-inch NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Fig. 20).
IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance.
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.
16

INSTALLATION
Install sediment trap in supply line as shown (See Fig. 20). Place sediment trap where it is within reach for cleaning. Place sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is installed wrong, heater may not run properly.

Fig. 20 – Gas Connection

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 50/50 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 )
The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of ½ psi (3.5 kPa).
