Figure 1 - Vent-Free Gas 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 (30 mL) of water for every 1,000 BTUs (.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 dehumidier 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.

AIR FOR COMBUSTION AND VENTILATION

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.

Providing Adequate Ventilation

All spaces in homes fall into one of the three following ventilation classications:

1. Unusually Tight Construction

2. Unconned Space

3. Conned Space The information on pages 8 through 10 will help you classify your space and provide adequate ventilation.

Conned and Unconned Space

A conned space is 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 unconned space as a space whose volume is not less than 50 cubic feet 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 unconned space.

This heater shall not be installed in a conned 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 dened 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

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

oors, 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”.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Determining if You Have a Conned or Unconned Space

Use this worksheet to determine if you have a conned or unconned 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

Gas water heater*

Gas furnace

Vented gas heater

Gas heater logs

Other gas appliances* +

Total =

*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 conned 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 ” on next page.

BTU/hr BTU/hr BTU/hr BTU/hr BTU/hr BTU/hr BTU/hr

Example: Gas water heater 30,000 BTU/hr Vent-free heater + 26,000 BTU/hr Total = 56,000 BTU/hr

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 unconned. If the actual BTU/hr used is less

than the maximum BTU/hr the space can support, the space is an unconned space. You will need no additional fresh air ventilation.

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 unconned space. When ventilating to an adjoining unconned space, you must provide two permanent openings: one within 12 inches of the ceiling and one within 12 inches of the oor 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 entilation grills or ducts.

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 oor. 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 2 - Ventilation Air from Inside Building

NOTE: Ba se n ot included. No t for use i n bedrooms or bathrooms.

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 unconned space. The combined spaces must have enough fresh air to supply all appliances in both spaces.

CONNECTING TO GAS SUPPLY

WARNING: A qualied 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 10.5 inches of water. If gas line pressure is higher, heater regulator damage 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

ttings.

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 Figure 12).

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.

Figure 12 - Gas Connection (inches)

* Purchase the optional CSA design-certied equipment shutoff valve from your dealer.

1414

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. Pointing the vent down protects it from freezing rain or sleet.

Install sediment trap in supply line as shown in Figure 12. 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.

Vent Pointing Down

INSTALLATION

Continued

CAUTION: Two gas line installations at the same time are prohibited. The access plate to the simple switching means

shall not be opened while the heater is in operation. This appliance can be used with propane or natural gas. It is shipped from the factory adjusted for use with propane. Only a qualied installer or service technician can perform gas selection and connecting to gas supply.

CAUTION: To avoid gas leakage at the inlet of regulator, a qualied installer or service technician must use steel or metal hex plug with sealant.

For changing from propane to natural gas supply:

1. Remove top screw from cover plate, See Figure 14, and rotate to expose fuel selection device.

2. For NATURAL GAS, press knob using a at screwdriver with a blade with thickness of a quarter and turn knob clockwise until the knob locks into the NG position (see Figure 15). Fuel selection device must be locked in the NG position. Do not operate heater between locked positions!

3. Rotate and close cover over fuel selection device and reinstall screw.

OPERATION

FOR YOUR SAFETY READ BEFORE LIGHTING

WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property

damage, personal injury or loss of life.

A. When lighting the pilot, follow these instructions exactly.

B. BEFORE LIGHTING, smell all around the appliance area for gas. Be sure to smell next to the oor because

some gas is heavier than air and will settle on the oor.

C. Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn

by hand, don’t try to repair it, call a qualied service technician or gas supplier. Forced or attempted repair may result in a re or explosion.

D. Do not use this appliance if any part has been under water. Immediately call a qualied service technician to

inspect the appliance and to replace any part of the control system and any gas control which has been under water.

WHAT TO DO IF YOU SMELL GAS

• Do not try to light any appliance.

• Do not touch any electric switch, do not use any phone in your building.

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

• If you cannot reach your gas supplier, call the re department.

1. STOP! Read the safety information on the side of the heater.

2. Make sure equipment shutoff valve is fully open.

3. Turn control knob clockwise to the OFF position.

for about thirty (30) seconds.This will allow air to bleed from the gas sysystem. If pilot does not stay lit, refer to Troubleshooting, pages 21 through 23. Also contact a qualied service technician or gas supplier for repairs. Until repairs are made, light pilot with match.

the front of burner. The pilot can be seen through the gill. If needed, keep pressing ignitor button until pilot lights. Note: If pilot does not stay lit, refer to Troubleshooting, pages 21 through 23. Also contact a qualified service technician or gas supplier for repairs. Until repairs are made, light pilot with match. To light pilot with match, see “Manual Lighting Procedure”.

7. 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 qualied service technician 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.

8. Turn control knob counterclockwise to desired heating level. The main burner should light. Set control knob to any heat level between 1 and 5.

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 the burner on and off. 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 HIGH (5) and LOW (1).

Shutting Off Burner Only (pilot stays lit )

Turn control knob clockwise to the PILOT position.

CAUTION: Do not try to adjust heating levels by using the equipment shutoff valve. Slightly press in control knob and turn counterclockwise to your desired heat level (1, 2, 3, 4, or 5). (see Fig. 20)

INSPECTING BURNER

Check pilot ame pattern and burner ame pattern often.

PILOT FLAME PATTERN

Figure 21 shows a correct pilot ame pattern. Figure 22 shows a incorrect pilot ame pattern. The incorrect pilot ame is not touching the thermocouple. This will cause the thermocouple to cool, which shuts the heater off. If

pilot ame pattern is incorrect:

• turn heater off (see “To Turn Off Gas to Appliance” on page 18)

• see Troubleshooting pages 21 through 23.

Figure 21 - Correct Pilot Flame Pattern

Figure 22 - Incorrect Pilot Flame Pattern

WARNING: If yellow tipping occurs, your heater could produce increased levels of carbon monoxide. If

burner ame pattern shows yellow tipping, follow instructions at bottom of this page.

Notice: Do not mistake orange ames with yellow tipping. Dirt or other ne particles enter the heater and burn causing brief patches of orange ame.

BURNER FLAME PATTERN

Figure 23 shows a correct burner ame pattern. Figure 24 shows an incorrect burner ame pattern. If burner ame pattern is incorrect then:

• turn heater off (see “To Turn Off Gas to Appliance” on page 18).

• see Troubleshooting, pages 21 through 23

CARE 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 qualied 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 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 ame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from where the pilot ame comes out of the pilot assembly (see Figure 25). 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.
