GENERAL INFORMATION
The VFST and VFPF Series Unvented Room
Heaters covered in this manual feature a unitized set of eight (8) ceramic fiber split logs.
These heaters have a standing pilot and may be
manually controlled through the use of an on/
off wall switch or wall thermostat or any combination of both of them.
A spark ignition system (piezo) allows the heater
pilot gas to be lit without the use of matches or
batteries and permits operation of the heater
during a power outage.
These heaters are fitted with a specially designed pilot (ODS) which responds to the
amount of oxygen available in the room and
shuts the heater off before the oxygen level
drops below 18%. The pilot can be relit only
when fresh air is available. Refer to the Combustion and Ventilation Air section.
The VFST and VFPF Series Unvented Room
Heaters must be built into a framed wall.
This heater has been tested to the standards of
ANSI Z21.11.2 unvented heaters.
Do not install these unvented room heaters in
a bedroom or bathroom as all units exceed
maximum allowable BTU/Hr input of 10,000.

Carbon Monoxide Poisoning: Early signs of
carbon monoxide poisoning are similar to the
flu with headaches, dizziness and/or nausea.
If you have these signs, obtain fresh air immediately. Turn off the gas supply to the
heater and have the Unvented Gas Heater
serviced as it may not be operating correctly.
• Due to high temperatures, the heater should
be located out of traffic and away from furniture
and draperies.
• Children and adults should be alerted to the
hazard of high surface temperatures and should
stay away to avoid burns or clothing ignition.
• Young children should be carefully supervised
when they are in the same room with the heater.
• Do not place clothing or other flammable
material on or near the heater for the purpose
of drying.
• Installation and repair should be done by a
qualified service person. The heater should be
inspected before use and at least annually by a
professional service person. More frequent cleaning may be required due to excessive lint from
carpeting, bedding material, etc. It is important
that control compartments, burners and circulating air passageways of the heater be kept clean.
• Allow the heater to cool before servicing.
Always shut off any electricity or gas to the
heater while performing service work.
• Do not install the VFST and VFPF series
heaters in a bedroom or bathroom.
• The installation must conform with local
codes or, in the absence of local codes with the
National Fuel Gas Code, ANSI Z223.1.
• The heater and its individual shut-off valve
must be disconnected from the gas supply
piping system while performing any tests of the
gas supply piping system at pressures in excess of 1/2 psig.
• Any safety screen or guard removed for
servicing the heater must be replaced prior to
operating the heater.
• The heater 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 1/2 psig.
• Keep heater area clear and free from combustible materials, gasoline and other flammable vapors and liquids.
• Do not use these appliances if any part has
been under water. Immediately call a qualified
professional service technician to inspect the
appliance and to replace any parts of the control
system and any gas control which have been
under water.
• Test gage connections are provided on the
front of the gas control valve (identified A for

latest edition of The National Fuel Gas Code
ANSI Z223.1 or NFPA54 which can be obtained
from The American National Standards Institute, Inc. (1430 Broadway, New York, NY,
10018) or National Fire Protection Association,
Inc. (Batterymarch Park, Quincy, MA, 02269).
Massachusetts And New York Requirements
These appliances are approved for installation
in the following USA locations listed in the
following:
Massachusetts:
These fireplaces are approved for installation
in the US state of Massachusetts if the following additional requirements are met-
• Installation and repair must be done by a
plumber or gas fitter licensed in the Commonwealth of Massachusetts.
• The flexible gas line connector used shall not
exceed 36 inches (92 centimeters) in length.
• The individual manual shut-off must be a Thandle type valve.
• Vent-Free appliances may NOT be installed in
bedrooms or bathrooms.
• A working smoke detector must be installed
in the area where vent-free appliances are
installed.
Seller of unvented propane or natural gasfired supplemental room heaters shall provide to each purchaser a copy of 527 CMR 30
upon sale of the unit.
New York:
These fireplaces are approved for installation
in the US state of New York, but not in New
York city.
COMBUSTION AND VENTILATION AIR
These heaters shall not be installed in a confined space. The heater may be located in
unusually tight construction provided the
space is unconfined, or if confined, is provided with two permanent openings communicating directly with an additional room(s)
of sufficient volume so that the combined
volume of all connected spaces meets the
criteria for an unconfined space, (National
Fuel Gas Code ANSI Z223.1 (latest edition),
Section 5.3). Generally 50 ft3 per 1,000 BTU
input of all operating appliances in the space.
The National Fuel Gas Code defines a confined space as a space whose volume is less
than 50 ft
of the aggregate input rating of all appliances
installed in that space and an unconfined
space as a space whose volume is not less
than 50 ft3 per 1,000 BTU/Hr (4.8 m3 per kw)
of the aggregate input rating of all appliances
installed in that space. Rooms communicating directly with the space in which the appliances are installed, through openings not
furnished with doors, are considered a part of
the unconfined space.
Unusually tight construction is defined as construction where:
a. wall and ceilings exposed to the outside
atmosphere have a continuous water vapor
retarder with a rating or one perm or less with
openings gasketed or sealed, and
b. weather stripping has been added on operable 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 wallceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines,
and at other openings.
Use the following equations to determine if you
have a confined or unconfined space.
1.Determine the volume of space — ft

2.Divide the volume of space by 50 ft3 to
determine the maximum BTU/Hr the space
can support.
______ (volume of space – ft
(Maximum BTU/Hr the space can support)
Example: 3072 ft3 / 50 ft3 = 40.96
or 40,960 BTU/Hr the space can support.
3.Add the BTU/Hr of all the fuel burning appliances in the space.
Vent-Free heater _______ BTU/Hr
Gas appliance #1* _______ BTU/Hr
Gas appliance #2 + _______ BTU/Hr
Total = _______ BTU/Hr
Example:
VFST Vent-free heater 32,000 BTU/Hr
Gas appliance #1 34,000 BTU/Hr
(water heater)
Total = 66,000 BTU/Hr
* Do not include direct-vent gas appliances.
Direct-vent is sealed combustion and draws
combustion air from the outdoors.
4. Compare the maximum BTU/Hr the space
can support with the actual amount of BTU/
Hr used.
_________ BTU/Hr
(max. the space can support)
_________ BTU/Hr
(actual amount of BTU/Hr used)
Example:
40,960 BTU/Hr
(max. the space can support)
66,000 BTU/Hr
(actual amount of BTU/Hr used)
The space in the above example is a confined
space because the actual BTU/Hr used is more
than the maximum BTU/Hr the space can support. You must provide additional fresh air.

WARNING: IF THE AREA IN WHICH THE
HEATER MAY BE OPERATED IS SMALLER
THAN THAT DEFINED AS AN UNCONFINED SPACE, PROVIDE ADEQUATE
COMBUSTION AND VENTILATION AIR BY
ONE OF THE METHODS DESCRIBED IN
THE NATIONAL FUEL GAS CODE, ANSI
Z223.1 1992, SECTION 5.3 OR APPLICABLE LOCAL CODES.
Your options are:
a.Rework equations adding the space of ad-
joining room(s). If the extra volume provides
an unconfined space, then remove door or
add ventilation grills between rooms. Refer
to National Fuel Gas Code, ANSI Z223.1
1992, Section 5.3.
b.Vent room directly to the outdoors. Refer to
National Fuel Gas Code, ANSI Z223.1 1992,
Section 5.3.
If the actual BTU/Hr used is less than the
maximum BTU/Hr the space can support, then
the space is an unconfined space. You will
need no additional fresh air ventilation for an
unconfined space.
LOCATION OF FIREPLACE
Carefully select the best location for installation of your VFST or VFPF series Unvented
Room Heater. The following factors should be
taken into consideration:
• Clearance to side wall, ceiling, woodwork
and windows.
• Location must not be affected by drafts
caused by kitchen exhaust fans, return air
registers for forced air furnaces/air conditioners, windows or doors.
• Installation must provide adequate ventilation and combustion air.
• Do not install the VFST or VFPF series heaters in a sleeping room or bathroom.
• Never obstruct the front opening of the
heater or restrict the flow of combustion and
ventilation air.
• This appliance may be installed in an aftermarket* manufactured (Mobile) Home, where
not prohibited by state or local codes.
*Aftermarket: Completion of sale, not for
purpose of resale, from the manufacturer.
• Minimize modifications to existing construction.
To ensure even heat distribution, it is best to
position the heater centrally within the rooms.
Make sure there is adequate ventilation where
the heater is installed. The gas appliance will
shut off if the oxygen level falls below 18%.
These appliances are uniquely suited for installations requiring a utility shelf positioned
directly above the fireplace. Utility shelves like
these are commonly used for locating television sets and decorative plants.
To provide for the lowest possible shelf surface, combustible materials used to support a
utility shelf directly above these appliances
should be positioned just above the appliance
top spacers. The minimum height from the
base of the appliance to the underside of combustible materials used to construct a utility
shelf is 43-1/4” (1099 mm).
The appliance should be mounted on a fully
supported base extending the full width and
depth of the unit. The appliance may be located
on or near conventional construction materials. However, if installed on combustible materials, such as carpeting, vinyl tile, etc., a metal
or wood barrier covering the entire bottom
surface must be used.
If the appliance is to be elevated above floor
level, a solid continuous platform must be
constructed.
WARNING: MAINTAIN MINIMUM
CLEARANCES.
Do not install in the vicinity of gasoline or other
flammable liquids. The heater must be kept
clear and free from these combustible materials and may not be located near where they are
stored.

Turn on gas supply and test for gas leaks,
using a gas leak test solution (also referred to
as bubble leak solution).
Note: Using a soapy water solution (50% dish
soap, 50% water) is an effective leak test
solution but it is not recommended, because
the soap residue that is left on the pipes/
fittings can result in corrosion over time. Never
use an open flame to check for leaks.
A. Light the appliance (refer to safety and
lighting instructions on page 15) (
See *Note
B. Brush all joints and connections with the
gas leak test solution to check for leaks. If
bubbles are formed, or gas odor is detected,
turn the gas control knob to the “OFF” position. Either tighten or refasten the leaking
connection and retest as described above.
).
Step 4. Position appliance into prepared framing, secure with 6d nails at the nailing flange
along each side.
Step 5. Connecting Gas Line – Make gas line
connections. All codes require a shut-off valve
mounted in the supply line.
Figure 10
trates two methods for connecting the gas
supply. Installation methods and materials
must be in compliance with local codes.
The gas control valve is located in the lower
control compartment. To access the valve
open the lower control compartment door
