INTRODUCTION- CONT’D.
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 strictly tr “supplemental” room heat use and should never be
installed as “sole source heating”.
ROOM HEATER SPECIFICATIONS
Your room heater comes packed in a single carton. Before installation, check
the rating plate to veril that the Model Number is correct and that the room
heater is equipped for the type gas you intend to use.

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 l_llowing 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 a W 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
Gas water heater …………………………..
58,000 Bm
Gas range (all burners & oven on) ………..
28,000 Bm
106,000 Btu
Page 4
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 t_radditional 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 t_r details. See Fibre 9 & Figure 10 below.

IMPORTANT
SAFETY BULLETIN ON YOUR GAS CONTROL SYSTEM FOR HEATING EQUIPMENT
AND PILOT LIGHT
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.
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.
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.
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 floor level.

IF YOU SMELL GAS, DON’T LIGHT IT
IF YOU CAN’T LIGHT IT, DON’T FIGHT IT!
American Gas Assoc iation
gamB
THIS IS NOT AN ADVERTISEMENT
· 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.
