IGNITION CONTROLS
Piezo ignitor allows ignition of the pilot without the use of
matches or batteries.
Millivolt and EcoLogic® 2.0 controls have 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). Both front and rear burners
are in operation to provide realistic glow
and yellow ame.
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.
THERMAL GENERATOR
The millivolt gas log pilot is tted with a millivolt generator
to provide power for remote activation.
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.

FIREGLASS PLACEMENT
NOTE: Two (2) bags of glass are supplied with the replace.
Both 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.
See Figure 54.

FLAME APPEARANCE
VFI33 Vent Free Gas Fireplace System
VISUAL FLAME CHECK
Flames from the pilot, front and rear burner should be
visually checked as soon as the heater is installed.
In addition, periodically check the ames visually during
operation.
CHECK THE PILOT FLAME
The pilot ame must always be present when the
heater is in operation. It should just touch the top of the
thermocouple tip for natural. Refer to Figure 55. for correct
pilot ame.
If the pilot ame does not touch the thermocouple, then
the main burner cannot function reliably. Refer to Figure
56. for incorrect shape of pilot ame.

THERMOSTAT AND MILLIVOLT CONTROL
In normal operation at full rate after 15 minutes, the following ame appearances should be observed:
Burner will have a random pattern of yellow ames. There
should be glowing embers on the front burner. NOTE: The
front ames and embers will be an opaque orange color
during the burn off time.
CAUTION: After a 15 minute pre-heat period, observe all
yellow ames to ensure there is no impingement with any
log. If any yellow ame is contacting any log, turn off log
set and allow to cool. Remove all logs and carefully reinstall following log placement instructions precisely. Relight
burner and check again for impingement of any ame on
log. If ame impingement cannot be eliminated, contact
your installer or dealer for assistance. Flame impingement
on logs may create soot and possible property damage.

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 four 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.
