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 selaTicelnanto
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 t\_r
"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 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
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 1per (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.

The entire heater should be checked and cleaned by a qualified service person before the start of each
heating season. More frequent cleaning may berequired 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.
