MATERIALS NEEDED FOR PROPER INSTALLATION

THE FOLLOWING MATERIALS ARE NEEDED TO PROPERLY INSTALL THIS HEATER IN A RESIDENTIAL TYPE HOME.

THE CHIMNEY USED MUST BE CAPABLE OF PROVIDING A MINIMUM OF .06 INCHES WATER COLUMN DRAFT.

1. Chimney Connector (also known as stove pipe): The chimney connector joins the heater to the chimney. The chimney connector pipes should be 6-inches in diameter 24-gauge minimum black steel. (Note: The number of 90 degree bends in the chimney connector installation for appliances, such as this heater, which have a top exit flue collar should be restricted to one. More than one 90 degree bend in the chimney connector could negatively affect chimney draft.)

2. Chimney: A code-approved masonry chimney. See the "MASONRY CHIMNEY REQUIREMENTS" portion of this manual for details.

A chimney complying with the requirements for Type 103-HT chimneys in the Standard for Chimneys, Factory Built, Residential Type and Building Appliance, UL 103. See the "METAL PREFABRICATED CHIMNEY REQUIREMENTS" portion of this manual for details.

3. Wall Thimble: A manufactured or site constructed device installed in combustible walls through which the chimney connector passes to connect to a masonry chimney. The wall thimble is intended to keep walls from igniting. A wall thimble is needed only if the chimney connector must pass through a combustible wall between the heater and the masonry chimney. See Figure 5 for wall thimble options.

4. Floor Protector: If the floor on which the heater is to be installed is wood or any other combustible material , the heater must be placed on a floor protector. The floor protector is to prevent the floor from catching fire from sparks or embers that might escape the heater or drop from the joints of the chimney connector pipe. The floor protector must protect the floor beneath and around the heater and chimney connector pipe as shown in Figure 9. The floor protector for this heater may be larger than the floor protector shown in Figure 9 but it must not be smaller than the floor protector shown in Figure 9. The floor protector must be a listed floor protector or a floor protector made of noncombustible inorganic material equal to or better than 3/4-inch thick material having a thermal conductivity R value of 1.5.

5. Chimney Shield: See step 11 of the "TO INSTALL THE HEATER" portion of this manual for details.

THIS HEATER IS NOT APPROVED FOR MOBIL HOME INSTALLATION.

SELECTING A LOCATION FOR YOUR HEATER

1. When locating the heater , consider safety, convenience, traffic flow, and the fact that the heater will need a chimney,chimney connector,and possibly a floor protector. Make sure none of these materials will be obstructed.

2. The heater should be located away from door ways and central heat outlets to reduce the chances of drafts, blowing smoke, ashes or sparks out of the heater during refueling or ash removal.

3. The heater should be located in an open area to allow for necessary clearances as specified within this manual.

4. Keep furniture, drapes, curtains, wood, paper and other combustibles far away from the heater.

5. Never install the heater in locations where gasoline, kerosene, charcoal lighter, or any other flammable liquids are stored

6. The heater should be located where a small supply of wood may be kept conveniently close but not within 36-inches of the heater.

7. The heater should not be located beneath overhanging shelves, low ceilings or other structures or elevated so that less clearance is created above the heater than is provided when the heater is normally installed in a room with a 7 foot minimum ceiling.

8. Be sure the chimney will be at least 10 feet from flammable gas or liquid storage tanks.

DANGER: DO NOT CONNECT THIS HEATER TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE. THERE IS A SERIOUS SAFETY RISK IF TWO APPLIANCES ARE CONNECTED TO THE SAME CHIMNEY FLUE.

CAUTION: The operation of exhuast fans such as bath room fans, attic fans, etc. might starve the heater of combustible

air creating a negative pressure in the room. Provide adequate ventilation in the room occompaning the heater.

MASONRY CHIMNEY REQUIREMENTS

If the heater is to be connected to a masonry chimney, the heater should not be installed until it is determined that the chimney is safe for use. Before installing the heater, have the chimney inspected by a building inspector, fire department, or qualified heating engineer. To prevent risk of walls, roof, or other combustibles catching fire from the extremely hot fire, smoke, and flue gases, and to obtain a proper draw, a chimney must meet the minimum standards for masonry chimneys established by the National Fire Protection Association (NFPA). Make certain the inspection agency is familiar with NFPA No. 211 and all local codes. Some of those minimum standards are listed here for your convenience.

1. The chimney must not be obstructed or clogged. An obstructed or clogged chimney could cause smoke and the dangerous carbon monoxide in smoke to spill back into your home.

2. Your masonry chimney must be supported on an adequate foundation and must have either a 5/8" thick fireclay or stainless steel lining. There must be at least 1/2-inch air space between the flue liner and the chimney wall. (See Figure 1.)

3. A chimney inside the house must have at least 2 inches of clearance to the combustible structure. A chimney outside the house must have at least 1 inch clearance to the combustible structure. Fire stops must be installed at the spaces where the chimney passes through floors and/or ceilings. (See Figure 2.) Insulation should be at least 2 inches from the chimney to leave an air space around the chimney. (See Figure 3.)

4. The flue lining of a masonry chimney must be smooth and have no leaks. The inside of the chimney flue liner should be no

FIGURE 1 MASONRY CHIMNEY REQUIREMENTS

smaller than 8 inches square or 6 inches round; a smaller chimney flue liner will be too restrictive to the flow of smoke and gases. A 6 inch diameter round liner is preferred because round flues draw better than square flues.

5. Since an oversized chimney flue contributes to the accumulation of creosote, the size of the chimney flue liner must be checked to determine that it is not too large for the heater. For

5/8" FIRECLAY OR STAINLESS STEAL FLUE LINER

this heater, the inside cross-sectional area of the chimney should be no more than 85 square inches to assure proper venting.

6. The top of the chimney must be at least 3 feet above the point where it comes through the roof, and at least 2 feet higher

MINIMUM 1/2" AIR SPACE

CHIMNEY WALL 4" NOMINAL

than any obstruction within a 10 foot radius.(See Figure 4.)

7. If the heater has insufficient draft, the draft may be improved

by extending the height of the chimney.

8. Make certain the chimney is kept clean and it is not blocked. Check for limbs overhanging the top of the chimney periodically.

FIGURE 4CHIMNEY HEIGHT REQUIREMENTS

A Chimney must be the required height above the roof or other obstruction for safety and for proper draft operation. The requirement is that the chimney must be at least 3 feet higher than the highest point where it passes through the roof and at least 2 feet higher than the highest part of the roof or structure that is within 10 feet of the chimney, measured horizontally. The above chimney heights are the minimum required

by codes for safety purposes to allow sparks existing in chimney time to cool before they land on the roof. Additional height will generally increase draft, improve heater operating characteristics and reduce back drafting and puffing problems due to wind A masonry chimney is shown above. However, height requirements are the same for a metal prefabricated chimney.
