PRODUCT FEATURES

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 kw) of gas input per hour. Use an unvented room heater as a supplemental heater (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 the proper size for the application, including adequate combustion air and circulation air.

2. If there is high humidity, the 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.

PREPARING FOR INSTALLATION

Before beginning assembly or operation of the product, make sure all parts are present. Compare parts with package contents list. If any part is missing or damaged, do not attempt to assemble, install, or operate the product. Contact customer service for replacement parts.

Before installing heater, make sure you have the items listed below:

• piping (check local codes)

• sealant (resistant to natural gas and propane/LP gas)

• equipment shutoff valve*

• test gauge connection*

• sediment trap

• tee joint

• pipe wrench

• exible gas hose (check local codes)

* A CSA design-certied equipment shutoff valve with 1/8-inch NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA design-certied equipment shutoff valve from your dealer.

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.

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

PRODUCING 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 7 through 9 will help you classify your space and provide adequate ventilation.

Conned and Unconned Space

A conned 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 unconning 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 unconned space. This heater should 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 (6x10

-11

kg 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 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” (page 9). 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.

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 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 unconned 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 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.

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or duct. 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 NFPA 54/ANS Z223.1. Air for Combustion and Ventilation for required size of ventilation grills or ducts.

Ventilation Air From Inside Building

This fresh air would come from adjoining unconned space. When ventilating to an adjoining unconned space, you must provide two permanent openings: one within 12 inches 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.

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.

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 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.

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).

CONNECTING TO GAS SUPPLY

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. 10).

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.

Fig. 10 - Gas Connection

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

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 Fig. 11. Pointing the vent down protects it from freezing rain or sleet.

Install sediment trap in supply line as shown in Fig. 11. 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.

Installation of Base Feet

Before installing heater to the base, please make sure you have the following items: (2) Base Feet, (4) Sheet Metal Screws. (Fig.12)

Installation Procedure:

1. Set back of heater on table with the bottom of heater extending outside the table edge.

2. Fasten Base Feet to heater using Sheet Metal Screws.

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).

Ignitor Button

Control knob

• Batteries are included.

• Remove batteries when depleted.

• Install/replace the batteries according to the type and quantity stated in table below.

• Do not mix old and new batteries. New batteries should be the same brand for best results.

• Be sure to observe proper polarity (+/-) when installing or replacing the batteries. Damage due to improper battery installation may void the warranty on the product.

• For remote control systems, maximize battery life by turning off the receiver when it is not in use.

• For long periods of non-operation, remove batteries from all components for safety.

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. Remove 4 screws - 2 screws on each side of the front panel.

3. Pull front panel forward.

4. 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 Fig. 23). 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.

5. Replace front panel when completed, using the screws removed
