Z21.11.2–2013, Unvented Heaters.
11. Do not install the heaters in a bathroom or bedroom.
12. Correct installation of the refractory cement or ceramic
ber logs, proper location of the heater, and annual
cleaning are necessary to avoid potential problems with
sooting. Sooting, resulting from improper installation or
operation, can settle on surfaces outside the replace.
See log placement instructions for proper installation.
13. Avoid any drafts that alter burner ame patterns. Do not
allow fans to blow directly into replace. Do not place
a blower inside burn area of rebox. Ceiling fans may
create drafts that alter burner ame patterns. Sooting
and improper burning will occur.
14. CAUTION: Candles, incense, oil lamps, etc. produce
combustion byproducts including soot. Vent-free
appliances will not lter or clean soot produced by
these types of products. In addition, the smoke and/
or aromatics (scents) may be reburned in the vent-free
appliance which can produce odors. It is recommended
to minimize the use of candles, incense, etc. while the
vent-free appliance is in operation.

IGNITION CONTROLS (MILLIVOLT ONLY)
Piezo ignitor allows ignition of the pilot without the use of
matches or batteries.
Millivolt control has four (4) positions:
OFF - All gas to the gas logs is shut off at the
valve.
IGN - Valve position to light/maintain a standing
pilot.
ON - Valve position to turn ON/OFF log set with
remote switch/thermostat.
LOW/HI - Variable position to control ame height
(heat output).
20308184
THERMAL GENERATOR (MILLIVOLT ONLY)
The millivolt gas log pilot is tted with a millivolt generator
to provide power for remote activation.
PILOT
The gas log heater is tted with a specially designed safety
pilot light (ODS assembly) which senses the amount of
oxygen available in the room and shuts the gas log heater
off if the oxygen level begins to drop below a satisfactory
level. The pilot can only be re-lit when adequate fresh air
is available.

VFF Vent Free Fireplace System
COLD CLIMATE OPTION
COLD CLIMATE OPTION (IPI Models Only)
NOTE: If you live in a cold climate, seal all cracks around
your appliance and wherever cold air could enter the room,
with noncombustible material. It is especially important to
insulate the outside chase cavity between the studs and
under the oor on which the appliance rests, if the oor is
above ground level.
Your replace is equipped with an intermittent pilot ignition
(IPI) control. An IPI control with a standing pilot option provides the dual benet of an economical and environmentally
responsible product and one which lights easily even in
the coldest climates. When in intermittent pilot mode (as
it comes from the factory), your pilot remains unlit until
needed, saving you fuel. Standing pilot mode, by comparison, is characterized by a continuously burning pilot.
The benet of a pilot which lights only when needed is fuel
savings. However, with no pilot burning in your replace,
units operating in colder climates may experience delayed
start up or lock out. Because colder air is heavier than
milder air and there is no pilot burning to maintain a warm
stable temperature in your rebox, establishing a draft to
aid ignition becomes difcult. This is perfectly normal but
can be somewhat frustrating.
To remedy this issue, your replace has been designed with
a cold climate pilot option, which, when active, maintains
a warmer temperature inside your rebox to make ignition
faster and more efcient. Operating your appliance in cold
climate (aka standing) pilot mode will prohibit the need for
multiple ignition attempts and will prevent the system from
delaying start up or locking out.
To activate the cold climate option, simply move the cold
climate toggle switch located on the right side of the black
control center to the “On” (left) position. (Figure 2) You can
operate your appliance in this mode regardless of whether
you are using a remote control, wall switch or thermostat.

ADEQUATE COMBUSTION AND VENTILATION AIR
This heater shall not be installed in a conned space or
unusually tight construction unless provisions are provided
for adequate combustion and ventilation air.
The National Fuel Gas Code, (ANSI Z223.1/NFPA54),
denes a conned 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
pace, and an unconned space as a space whose volume
is not less than 50 cubic feet per 1,000 BTU per hour (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 a conned space.
WARNING: If the area in which the heater
is operated does not meet the required
volume for indoor combustion air, combustion
and ventilation air shall be provided by one of
the methods described in the National Fuel Gas
Code, ANSI Z223.1/NFPA 54, the International
Fuel Gas Code or applicable local codes.

FIREPLACE INSTALLATION
VFF Vent Free Fireplace System
Unusually tight construction is dened as construction
where:
a. walls and ceilings exposed to the outside atmosphere
have a continuous water vapor retarder with a rating of
1 perm (6 x 10
gasketed or sealed, and
b. weather stripping has been added on openable windows
and doors, and
c. caulking or sealants are applied to areas such as joints
around window and door frames, between sole plates
and oors, between wall-ceiling joints, between wall
panels, at penetrations for plumbing, electrical and gas
lines and other openings.
The following formula can be used to determine the maximum heater rating per the denition of unconned space:
BTU/Hr = (L1 + L2) Ft x (W) Ft x (H) Ft
Consider two connecting rooms with an open area
between, with the following dimensions:
L1 = 151/2 Ft., L2 = 12 Ft., W = 12 Ft., H = 8 Ft.
If there were a door between the two rooms the calculation
would be based only on the room with the heater.

GLASS ONLY PLACEMENT
NOTE: Two (2) bags of glass are supplied with the VFF32
replace and three (3) are supplied with the VFF36 replace. All of the supplied bags may be used to cover the
entire oor and burner. We advise against using additional
glass as too much can cut off the proper amount of air the
burner needs to operate cleanly. This may cause sooting.
1. Spread glass evenly in one layer over the entire oor
and burner. Be sure to use a single layer only over the
ported area so as not to impinge the ame.
2. Turn burner on and adjust glass over ported areas to
achieve an even, clean ame.

OPERATING INSTRUCTIONS
Avoid any drafts that alter burner ame patterns. Do
not allow fans to blow directly into the replace. Do not
place a blower inside the burn area of the rebox. Ceiling
fans may create drafts that alter ame patterns. Sooting
and improper burning will result.
During manufacturing, fabricating and shipping, various
components of this appliance are treated with certain oils,
lms or bonding agents. These chemicals are not harmful,
but may produce annoying smoke and smells as they are
burned off during the initial operation of the appliance,
possibly causing headaches or eye or lung irritation. This
is a normal and temporary occurrence.
The initial break-in operation should last two to three hours
with the burner at the highest setting. Provide maximum
ventilation by opening windows or doors to allow odors to
dissipate. Any odors remaining after this initial break-in will
be slight and will disappear with continued use.
This appliance must not be used with glass doors in the
closed position. This can lead to pilot outages and severe
sooting outside the replace.
