2. Remove all protective packaging applied to heater for shipment.
3. Check heater for any shipping damage. If heater is damaged. promptly inform dealer where you bought heater.

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 (30ml) of water for every 1,000 BTU’s (.3KW’s) 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 insure 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.

FRESH 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 insure proper fresh air for this and other fuel-burning appliances in your home.

PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code. NFPA 54/ANS Z223.1, Section 5.3. Air for Combustion and 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 4 through 6 will help you classify your space and provide adequate ventilation.
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 -11 kg per pa-sec-m2) or less with openings gasketed or sealed and
b. weather stripping has been added on openable windows and 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 6.
If your home does not meet all of the three criteria above see
Determining Fresh-Air Flow for Heater Location, page 5.
Confined and Unconfined Space
The National Fuel Gas Code ANS Z223.1 defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (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 per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space.
Rooms communicating 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 communicating only if there are doorless passageways or ventilation grills between them.

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).
   Length×Width×Height= cu.ft. (volume of space)
   Example: Space size 18ft. (length)×16ft.( width)×8ft. (ceiling height)=2304cu. 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)
   Example: 2304 cu. ft. (volume of space) 50 cu.ft.=46.1 or 46.100(maximum Btu/Hr the space can support)
   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, ANS Z223.1, Section 5.3 or applicable local codes.

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 Fireplace logs …………………Btu/Hr
   Other gas appliances + ………………Btu/Hr
   Total =…………………………….. Btu/Hr
   Example:
   Gas water heater 44,000 Btu/Hr
   Vent free heater + 10,000 Btu/Hr
   Total = 54,000 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 : 46,080 Btu/Hr(maximum the space can support)
   54,000 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 are. 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 5.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 6 .
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.

AIR FOR COMBUSTION AND VENTILATION Continued
VENTILATION AIR
Ventilation Air From Inside 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″ of the ceiling and one within 12″ of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 2). You can also remove door into adjoining room (see option 3, Figure 2). Follow the National Fuel Gas Code NFPA 54/ANS Z223.1. Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts

WARNING: 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.

VENTILATION AIR

Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts: You must provide two permanent openings: one within 12″ of the ceiling and one within 12″ 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, Section 5.3.
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.

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.

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

CONNECTING TO GAS SUPPLY
WARNING: A qualified service person must connect heater gas supply. Follow all local codes.
WARNING: This appliance requires a 3/8″ NPT (National Pipe Thread) inlet connection to the pressure regulator.
WARNING: Never connect heater to private (non-utility) gas well. This gas is commonly known as well-head gas.

IMPORTANT: Check your gas line pressure before connecting heater to gas line. Gas line pressure must be no greater than 10.5 inches of water.
If gas line pressure is higher, heater regulator damage could occur.

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 large enough diameter to allow proper gas volume to heater.
If pipe is too small, undue loss of pressure will occur.

Typical Inlet Pipe Diameters
All models up to 20,000 BTU’s use 3/8’’ or greater pipe;
All models 25,000 BTU’s and higher, use 1/2” or greater pipe.
Installation must include an equipment shutoff valve, union, and plugged 1/8″ NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be up stream from heater (see Figure 13).

*A CSA/AGA design-certified equipment shutoff valve with 1/8″ NPT tap is an acceptable alternative to test gauge connection. Purchase the CSA/AGA design-certified equipment shutoff valve from your dealer.

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.

CAUTION: Use pipe joint sealant that is resistant to natural gas.
Install sediment trap in supply line as shown in Figure 13. Locate sediment trap where it is within reach for cleaning. Locate 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.

IMPORTANT: Hold pressure regulator with wrench when connecting it to gas piping and/or fittings.

CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all leaks at once.

   Note: You may be running this heater for the first time after hooking up to gas supply.
   If so, the control knob may need to be pressed in for 30 seconds. This will allow air to bleed from the gas system.
   If control knob does not pop up when released, contact a qualified service person or gas supplier for repairs.

6. With control knob pressed in, push down and release ignitor button. This will light pilot. The pilot is attached to the front of burner. The pilot can be seen through the glass panel. If needed, keep pressing ignitor button until pilot lights.
   Note: If pilot does not stay lit, refer to Troubleshooting, pages 14 through

7. Also contact a qualified service person or gas supplier for repairs. Until repairs are made, light pilot with match.To light pilot with match, see Manual Lighting Procedure.

8. Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob.
   If control knob does not pop up when released, contact a qualified service person or gas supplier for repairs.
   Note: If pilot goes out,repeat steps 3 through 7.This heater has a safety interlock system. Wait one(1) minute before lighting pilot again.

9. Turn control knob counterclockwise to desired heating level. The main burner should light. Set control knob to any heat level between HI and LO.

CAUTION: Do not try to adjust heating levels by using the equipment shutoff valve.

THERMOSTAT CONTROL OPERATION
The thermostatic control used on this model differs from standard thermostats.Standard thermostats simply turn on and off the burner. The thermostat used on this heater senses the room temperature. At times the room may exceed the set temperature.
If so,the burner will shut off. The burner will cycle back on when room temperature drops below the set temperature.
The control knob can be set to any comfort level between HI and LO.
Note: The thermostat sensing bulb measures the temperature of  air near the heater cabinet.This may not always agree with room temperature(depending on housing construction, installation location, room size, open air temperatures,etc.)
Frequent use of your heater will let you determine your own comfort levels.

INSPECTING BURNER
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 20 shows a correct pilot flame pattern. Figure 21 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down. If pilot flame pattern is incorrect, as shown in Figure 21.

• turn heater off (see To Turn Off Gas to Appliance on page 11 for non-thermostat models or page 12 for thermostat models.)
• see Troubleshooting. pages 14 through 16.

BURNER FLAME PATTERN
Figure 22 shows a correct burner flame pattern. Figure 23 shows an incorrect burner flame pattern. If burner flame pattern is incorrect, as shown in Figure 23.
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 mistake orange flames with yellow tipping. Dirt or other fine particles enter the heater and burn causing brief patches of orange flame.

• turn heater off (see To Turn Off Gas to Appliance pages10 & 11 for non-thermostat models and page 12 for thermostat models)
• see Troubleshooting. pages 14 through 16

CLEANING AND MAINTENANCE

WARNING: Turn off heater and let cool before servicing.
CAUTION: You must keep control areas, burner, and circulating air passageways of heater clean.
Inspect these areas of heater before each use. Have heater inspected yearly by a qualified service person.
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 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 Figure 24).
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.
