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 signs of Carbon Monoxide poisoning resemble influenza, with headaches, dizziness,
or nausea. If you develop these symptoms GET FRESH AIR AT ONCE. Turn off heater and call a qualified serviceman to
check heater. Some people are more affected by Carbon Monoxide than others: Including pregnant women, persons with
a heart or lung disease, anemia, those under the influence of alcohol, and those at high altitudes.
OPERATION
The Cozy thermostatically 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 FOR “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 verify 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 energy 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 following guide provides good general rules for classifying and
properly ventilating most homes.
The National Fuel Gas Code ANSI Z223.1 defines a confined space as “a space whose volume is less than 50 cubic feet
per 1,000 Btu per hour (4.8m³ per Kw) of the aggregate input rating of all 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 (4.8m³ per Kw)
of the aggregate input rating of all appliances installed in that space. Rooms communicating 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 following 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 length x width x height. NOTE: Include any adjoining rooms that
cannot be separated by closing a door or that have a air exchange grille that cannot be closed between rooms.
EXAMPLE: Area size 25 ft. x 15 ft. x 7-1/2 ft. = 2,812.5 cubic feet.
STEP 2. Divide area cubic feet by 50. EXAMPLE: 2,812.5 ) 50 = 56.25. Multiply this number by 1,000 for total Btu input
room can support. E XAMPLE: 56.25 x 1,000 = 56,250 Btu.
STEP 3. List all gas burning appliances in this area and total the combined Btu input. EXAMPLE:
Cozy vent free heater……………………..
Gaswaterheater…………………………..
Gas range (all burners & oven on)………..
20,000 Btu
58,000 Btu
28,000 Btu
106,000 Btu

FRESH AIR FOR COMBUSTION, VENTILATION AND HEAT DISTRIBUTION - CONT’D.
STEP 4. Compare the total Btu the area can support (from Step 2) to the total Btu in the area the heater will be installed
(from Step 3). If the total from Step 2 is larger this is considered an unconfined space, if Btu total from Step 3 is larger this
is considered a confined space and provisions must be made for 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 (6x10-11 Kg
per pa-sec-m²) or less with openings gasketed or sealed, and, (B) Weatherstripping has been added enable 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 wall 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, 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 for
details. See Figure 9 & Figure 10 below.

INSTALLATION - CONTINUED
3)
4)
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.
All models may be wall mounted using the factory supplied (standard) wall mounting bracket. Additionally all
models may be installed freestanding, by adding the optional VF-FSK Floor Stand Kit and using an approved, fire
resistant floor mat (available from factory). NOTE: Both wall and floor mount installations require hard piping.
If optional blower is to be added, locate heater so there is safe access to an electrical outlet.
5)
CLEARANCES
1)
Maintain adequate accessibility clearances for
36”
servicing and proper operation.
2)
Minimum clearances as viewed from front of
heater, see Fig. 1. 3” clearance below heater
shall be measured from top surface of carpeting,
tile, etc.
3)
If VF-FSK Free Standing Kit is used and the
heater is installed directly on carpeting, tile, or

GAS CONNECTION
STEP 1.
NOTE:
Make the gas connection between the manual shut off valve and regulator located inside
heater cabinet. Hold regulator when tightening connection to prevent damage to regulator
and internal tubing. See Figure 6 for completed installation.
All piping and connection must be checked for leaks by the installer. If connections are not
exposed, a pressure test must be run. The appliance and its individual shut off valve must
be disconnected from the gas supply piping system during any pressure testing at pressures
in excess of ½ psig (3.5 kPa). The appliance must be isolated from the gas supply piping
system by closing its individual manual shut off valve during any pressure testing of the gas
supply piping system at test pressures equal to or less than ½ psig (3.5kPa).

All orificing and pressure setting was done at the factory and, with correct supply pressure will provide a safe, efficient
source of heat. If installed above 2,000 ft. elevation, the main burner orifice must be changed. See orifice chart on Page 10
for correct size. If there is any question about the manifold pressure, have a qualified serviceman check using a
manometer. The manifold pressure should be 3.0” w.c. for natural gas and 10.0” w.c. for L.P. gas. A proper burner flame
will have a soft blue outer mantel approximately 3.5 in. tall with a darker blue inner mantel approximately 1/4” tall.

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 jamb 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
Burner may be cleaned by using a low pressure air hose, or soft brush.
ODS/PILOT
STEP 1.
STEP 2.
STEP 3.
Remove bottom front panel.
Disconnect pilot line from pilot.
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 safe and reliable operation. Although safety mechanisms are
built-in, the potential for hazard exists. This information is intended to help you avoid these hazards.
WHAT TO DO IF YOU SMELL GAS . . .
YOUR GAS CONTROL AND PILOT LIGHT
•
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.
SYSTEM
•
Your gas control and pilot light system has a
safety device whose purpose is to shut-off the
gas supply to the appliance 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.
•
•
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.P.-gas at floor level. LP-gas is
heavier than air and may temporarily
exist at floor level.
•
IF YOU SMELL GAS, DON’T LIGHT IT
•
•
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.
IF YOU CAN’T LIGHT IT, DON’T FIGHT IT!
