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 fl ame height
(heat output).
20308011
PILOT
The gas log heater is fi 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 fi tted with a millivolt generator
to provide power for remote activation.

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 fl oor on which the appliance rests, if the fl oor is
above ground level.
Your fi replace is equipped with an intermittent pilot ignition
(IPI) control. An IPI control with a standing pilot option provides the dual benefi t 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 benefi t of a pilot which lights only when needed is fuel
savings. However, with no pilot burning in your fi 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 fi rebox, establishing a draft to
aid ignition becomes diffi cult. This is perfectly normal but
can be somewhat frustrating.
T o remedy this issue, your fi replace has been designed with
a cold climate pilot option, which, when active, maintains
a warmer temperature inside your fi rebox to make ignition
faster and more effi cient. 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) Y ou can
operate your appliance in this mode regardless of whether
you are using a remote control, wall switch or thermostat.

the space in which the appliances are installed, through
openings not furnished with doors, are considered a part
of a confi ned space.
Unusually tight construction is defi ned 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

c. caulking or sealants are applied to areas such as joints
around window and door frames, between sole plates
and fl 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 defi nition of unconfi ned 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.
