UNPACKING

1. Remove heater from carton.

2. Remove all protective packaging applied to heater for shipping

3. Check heater for any shipping damage. If heater is damaged, promptly inform dealer where you bought heater.

4. 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 KWs) of gas input per hour. Unvented room heaters are recommended as supplemental heat (a room) rather than a primary heat source (an entire house). 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 sized properly for the application, including ample combustion air and circulation air.

2. If high humidity is experienced, 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.

5. 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.

Providing Adequate Ventilation

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, ANSI Z223.1/NFPA 54, the INTERNATIONAL FUEL GAS CODE, or applicable local codes.The following are excerpts from National Fuel Gas Code, ANSI Z223.1/ NFPA 54. Air for Combustion and Ventilation. All spaces in homes fall into one of the three following ventilation classifications:

1. Unusually Tight Construction

Igniter button Igniter button

2. Unconfined Space

3. Confined Space The information on the followed pages will help you classify your space and provide adequate ventilation.

Confined and Unconfined Space

The National Fuel Gas Code, ANSI Z223 .1/NFPA 54 defines a confined space as a space whose volume is less than 50 cu. ft. per 1,000 BTU/hr (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space and an unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 BTU/hr (4.8 m3 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 odorless 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 gasket or sealed and

b) Weather stripping has been added on openable windows 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”. If your home does not meet all of the three criteria above, proceed to “Determining Fresh-Air Flow For Heater Location”.

6. DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Using 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 cubic feet to determine the maximum BTU/hr the space can support. (volume of space) ÷ 50 cu. ft. =(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 Gas heater logs BTU/hr Other gas appliances* + BTU/hr Total = BTU/hr

Example: Gas water heater 30,000 BTU/hr Vent-free heater + 26,000 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: Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined

space, a) remove door to adjoining room or add ventilation grills between rooms. See “Ventilation Air From

Inside Building ” on next page. b)Vent room directly to the outdoors. See “Ventilation Air From Outdoors ” on next page. 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.

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.

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 lnside Building

This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12 inches of the ceiling and one within 12 inches of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 2). You can also remove the door into adjoining room (see option 3, Figure 2). Follow the National Fuel Gas Code. ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation for required size of ventilation grills or ducts.

Figure 2 - Ventilation Air from Inside Building

NOTE: Base not included. Not for use in bedrooms or bathrooms.

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent openings: one within 12 inches of the ceiling and one within 12 inches 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, ANSI Z223.1/ NFPA 54, Air for Combustion and Ventilation for required size of ventilation grills or ducts.

Figure 3 - Ventilation Air from Outdoors

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.

7. 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.

Caution: If you install the heater in a home garage:

Heater pilot and burner must be at least 18 inches above the floor. Place heater where moving vehicle will not hit it.

WARNING: A qualified service person must install heater. Follow all local codes.

WARNING: Never install the heater

 in a recreational vehicle  where curtains, furniture, clothing, or other flammable objects are less than 36 inches from the

front, top, or sides of the heater

 in high traffic areas  in windy or drafty areas

CAUTION: This heater creates warm air currents. These

currents move heat to wall surfaces next to heater. Installing heater next to vinyl or cloth wall coverings or operating heater where impurities (such as tobacco smoke, aromatic candles, cleaning fluids, oil or kerosene lamps, etc.) in the air exist, may cause walls to discolor.

IMPORTANT: Vent-free heaters add moisture to the air. Although this is beneficial, installing heater in rooms without enough ventilation air may cause mildew to form too much moisture. See Air for Combustion and Ventilation.

8. 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. 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.

NATURAL GAS MODELS:

CAUTION: Check your gas line pressure before connecting heater to gas line. Gas line pressure

must be no greater than 11 inches of water. If gas line pressure is higher, damage on appliance

regulator could occur.

PROPANE MODELS:

CAUTION: Never connect heater directly to the gas 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).

IMPORTANT: Install an equipment shutoff valve in an accessible location where the gas pipe goes

indoors. 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. 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, appliance regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 8. Pointing the vent down protects it from freezing rain or sleet.

Check pilot flame pattern and burner flame pattern often.

PILOT FLAME PATTERN

Figure 12 shows a correct pilot flame pattern.

Figure 12

WARNING: If yellow tipping occurs, your heater could produce increased levels of carbon monoxide. If burner flame pattern shows yellow tipping, follow instructions at bottom of this page. Notice: Do not confuse orange flames with yellow tipping. Dirt or other fine particles enter the heater and burn causing brief patches of orange flame

10. CARE AND MAINTENANCE

WARNING: Turn off heater and let cool before servicing CAUTION: You must keep control areas, burner, and circulating air passageways of the heater clean.

Inspect these areas of heater before each use. Have heater inspected yearly by a qualified service technician. Heater may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.

ODS/PILOT AND BURNER

Use a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean.

CLEANING BURNER PILOT AIR INLET HOLE

We recommend that you clean the unit every 2,500 hours of operation or every three months. We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recommend using compressed air no greater than 30 PSl. Your local computer store, hardware store, or home center may carry compressed air in a can. You can use a vacuum cleaner in the blow position. If using compressed air in a can, please follow the directions on the can. If you don’t follow directions

Figure13

on the can, you could damage the pilot assembly.

1. Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes.

2. Inspect burner and pilot for dust and dirt.

3. Blow air through the ports/slots and holes in the burner. Also clean the pilot assembly. A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from where the pilot flame comes out of the pilot assembly (see Figure13. With the unit off, lightly blow air through the air inlet hole. You may blow through a drinking straw if compressed air is not available.

CABINET Air Passageways

Use a vacuum cleaner or pressurized air to clean.

Exterior

Use a soft cloth dampened with a mild soap and water mixture. Wipe the cabinet to remove dust

1) Use a soft cloth dampened with a mild soap and water mixture.

2) Wipe the cabinet to remove dust.

11. TROUBLE SHOOTING

WARNING: If you smell gas:

1) Open the window and door immediately.

2) Shut off gas supply.

3) Do not try to light any appliance.

4) Do not touch any electrical switch; do not use any phone in your building.

5) Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

6) If you cannot reach your gas supplier, call the fire department. IMPORTANT: Operating heater where impurities in air exist may create odors. Cleaning supplies, paint,

paint remover, cigarette smoke, cements and glues, new carpet or textiles, etc., create fumes. These fumes may mix with combustion air and create odors.

WARNING: Only a qualified service technician 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.
