INTRODUCTION

Read these installation and operating instructions carefully before you install or attempt to use this vent free room heater. If you do not understand any part of these instructions, consult local authorities, a qualified installer, service agency, or the gas supplier. FAILURE TO READ OR UNDERSTAND THESE INSTRUCTIONS CAN RESULT IN MALFUNCTION, INEFFICIENT OPERATION, PROPERTY DAMAGE, SERIOUS INJURY OR DEATH.
These installation instructions are a general guide and do not supersede applicable local codes and ordinances. Before planning or beginning the installation be sure it complies with allphases of the local heating code. Or, in the absence of local codes, with the latest edition of the National Fuel Gas Code, ANSI.Z223.1/NFPA54. A copy of which is available from the American Gas Association, 1515 Wilson Blvd., Arlington, Virginia22209.
The design of this appliance was certified to comply with the latest edition of ANSI Z21.11.2, also available from the American Gas Association.
For your protection this heater is equipped with an Oxygen Depletion Sensor (ODS) pilot system. Never operate heater if ODS has been damaged or tampered with as this could expose you to Carbon Monoxide (a colorless, odorless gas) that could result in injury or death. Early simls of Carbon Monoxide poisoning resemble intluenza, with headaches, dizziness, or nausea. If you develop these symptoms GET FRESH AIR AT ONCE. Turn off heater and call a qualified selaTicelnan to check heater. Some people are more affected by Carbon Monoxide than others: Including pre_lant women, persons with a heart or lung disease, anemia, those under the influence of alcohol, and those at high altitudes.
OPERATION
Infrared heaters “heat like the sun” with ahnost instantaneous, safe, clean burning “waves” of intiared heat. Like the sun, they must “see” the object to be heated. Make sure they are installed away tiom furniture or any other object which might block the intiared “waves”. The Cozy thennostatically controlled units offer the additional benefit of automatically cycling the heating to maintain just the right room temperature. Ventfree gas room heaters are designed strictlytr “supplemental” room heat use and should never be installed as “sole source heating”.

FRESH AIR FOR COMBUSTION, VENTILATION AND HEAT DISTRIBUTION

With todays eneigy efficient homes, it is possible to make your home so air tight that it can result in stale air, dry rot, mold development and host of other related problems. Gas burning appliances need fresh air for combustion as well as for good distribution of heated air throughout the home. The fllowing mlide provides good general rules for classifying and properly ventilating most homes.
“The National Fuel Gas Code ANSI Z223.1/NFPA54 defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.81n3per Kw) of the ag_egate input rating ofatt appliances installed in that space and an unconfined space as a space whose volume is equal to or greater than 50 cubic feet per 1,000 Btu per hour (4.8m 3per Kw) of the aggregate input rating ofalt appliances installed in that space. Rooms comlnunicating directly with the space in which the appliance is 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 for adequate combustion and ventilation air are made. Use the l\_llowing example to determine if the heater is being installed in a confined or unconfined space.”
STEP 1. First find the cubic feet of area to be heated lenath x width x heiaht. NOTE: Include aW adjoining rooms that cannot be separated by closing a door or that have a air exchange _itte that cannot be closed between rooms.
EXAMPLE: Area size 25 ft. x 15 ft. x 7-1/2 ft. 2,812.5 cubic feet.
STEP2. Divide area cubic feet by 50. EXAMPLE: 2,812.5 50 56.25. Multiplythisnumberby 1,000 for total Btu input room can support. EXAMPLE: 56.25 x 1,000 56,250 Bin.
STEP3. List all gas burning appliances in this area and total the combined Btu input. EXAMPLE:
Cozy vent fiee heater. ……………………. 20,000 Bm
Gaswater heater ………………………….. 58,000 Bm
Gas range (all burners & oven on) ……….. 28,000 Bm
106,000Btu

FRESH AIR FOR COMBUSTION, VENTILATION AND HEAT DISTRIBUTION – CONTD.
STEP 4. Compare the total Btu the area can support (from Step 2) to the total Btu in the area the heater wilt be installed (fioln Step 3). If the total froln Step 2 is larger this is considered an unconfined space, ifBtu total froln Step 3 is larger this is considered a confined space and provisions must be made additional combustion and ventilation air. EXAMPLE:
Btu area can support is 56,250, total Btu in area is 106,000 this would be a confined space.
NOTE: A third construction class is one with unusually tight construction, defined as, construction where: (A) Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of 1 per (6x 10-11 Kg per pa-sec-m 2) or less with openings gasketed or sealed, and, (B) Weatherstripping has been added on openabte 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 walt panels, at penetration for plumbing, electrical, and gas lines, and at other openings.
“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/NFPA54, Section 5.3 or applicable local codes.” Examples would be to provide two permanent openings either to an adjoining room, or to the outside. See the National Fuel Gas Code details. See Fibre 9 & Figure 10 below.

INSTALLATION

Installation and service must be performed by a qualified installel; service agency or the gas supplier.
LOCATION

1. For most efficient performance, locate heater as centrally as possible in the area to be heated.
2. Do not install heater in a closet, alcove or small hallway where the heater could be isolated from the space to be heated and adequate combustion air by closing a door.
3. Protect heater from wind, high traffic areas, and drafts (such as doorways, locations that get direct air from a ceiling fan, etc.) as this will cause nuisance pilot outage.
4. Alhnodels may be walhnounted. Model No. VFM 10, VFT10, VFM20, VFT20, VFM30 & VFT301nay be fiee standing by adding optional VF-FSK floor stand kit. These floor mounted units must also have an approved, fire resistant floor base (available fiom factory) and must be hard piped.
5. If optional blower is to be added, locate heater so there is safe access to an electrical outlet.

CLEARANCES

1. Maintain adequate accessibility clearances for servicing and proper operation.

PROPER OPERATION

ODS / PILOT FLAME
The pilot pressure has been pre-set at the factory and with proper supply pressure will provide a safe, reliable ignition source. See Figure 6.

BURNER FLAME
All orificing and pressure setting was done at the factory and, with proper supply pressure, wilt provide a safe, efficient source of heat. However, if any questions about lnanifold pressure, have a qualified selwiceman check with a manometer, Natural Gas will be 5″, L.R Gas will be 10″ w.c. A proper burner flame (See Figure 7) will produce a reddish-orange flow on the surface of the ceramic burner plaques. If the burner flame has blue streamers or the flame is floating offthe surface of the plaques, turn heater offand call a qualified selwice person. Do not operate heater if all plaques are not glowing.
NOTE: There wilt be approximately ¼” space on the sides and top of the burner that will not glow.
VFM20: When turned to the “LO” setting the two middle plaques wilt light and glow. When valve is turned to “HI” then all four plaques will be lit.

MAINTENANCE

The entire heater should be checked and cleaned by a qualified service person before the start of each heating season. More frequent cleaning may be required due to excessive lint conditions from carpeting, bedding material, etc.
CABINET
To clean the cabinet and hearth and j arab assemblies of your heater, turn off and allow to cool, then wipe with a soft damp cloth. This will remove any dust. Never use metal polish, furniture wax, or any type of cleaning solution as this could cause odors when the heater is turned back on.
MAIN BURNER
Burners may be cleaned by using a low pressure air hose, or soft brush. Be careful not to damage the ceramic plaque.
ODS/PILOT
STEP 1. Remove bottom front panel.
STEP 2. Disconnect pilot line from pilot.
STEP 3. Use a low pressure air hose to blow through pilot and through ODS opening in side of pilot.
WARNING: Never insert anything into any of the openings in the pilot as this could damage the Oxygen Depletion System and expose the homeowner to Carbon Monoxide poisoning. WARNING : After any servicing or cleaning make sure heater is completely re-assembled and check for gas leaks.

IMPORTANT SAFETY BULLETIN ON YOUR GAS CONTROL AND PILOT LIGHT SYSTEM FOR HEATING EQUIPMENT WHAT YOU DON’T KNOW CAN HURT YOU.
Your pilot light system has been designed for sate and reliable operation. Although safety mechanisms are built-in, the potential for hazard exists. This information is intended to help you avoid these hazards.
YOUR GAS CONTROL AND PILOT LIGHT SYSTEM
Your gas control and pilot light system has a safety device whose purpose is to shut-offthe gas supply to the appfiance if the pilot light goes out. If you have trouble lighting the pilot or keeping it lit, it may mean that this safety device is warning you that there is a problem with your system. Inspection and repairs or replacement must be made by a trained gas service technician. TAMPERING IS DANGEROUS
The pilot safety system may also not work if you do not follow the lighting instructions carefully or if you tamper with the gas control that you use to light the pilot. Tampering with the gas control, particularly with tools, can damage the safety mechanism in the control and can allow gas to leak. This can result in a fire or explosion causing property damage, personal injury or death.
IF YOU SMELL GAS, DON’T LIGHT IT IF YOU CAN’T LIGHT IT, DON’T FIGHT IT! THIS IS NOT AN ADVERTISEMENT

WHAT TO DO IF YOU SMELL GAS …

• Do not try to light any appliance.
• Do not touch any electrical 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 fire department.
  Installation and service must be performed by a qualified installer, service agency or the gas supplier.
  Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.

CRITICAL SAFETY POINTS TO REMEMBER…

• Your gas has been odorized so that you can smell it. Always smell around for gas before lighting your appliance.
• Sniff for L.E-gas at floor level. LP-gas is heavier than air and may temporarily exist at floor level.
• If you smell gas, do not attempt to light the pilot. Do not cause a spark by turning on or off electrical switches or appliances or by using the phone. Turn off the gas to the appliances and call your gas supplier from another location.
• If your gas control has gotten wet as the result of flooding or other wetting, it must be replaced immediately by a trained gas service technician. Water can lead to damage of the internal safety mechanism in the gas control and can create a hazardous condition.
