without derating for elevations up to 4,500 feet (1,370
m) above sea level.

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 floor on which the appliance rests, if the floor is
above ground level.
Your fireplace is equipped with an intermittent pilot ignition
(IPI) control. An IPI control with a standing pilot option pro-
vides the dual benefit 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 com-
parison, is characterized by a continuously burning pilot.
The benefit of a pilot which lights only when needed is fuel
savings. However, with no pilot burning in your fireplace,
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 firebox, establishing a draft to
aid ignition becomes difficult. This is perfectly normal but
can be somewhat frustrating.
To remedy this issue, your fireplace has been designed with
a cold climate pilot option, which, when active, maintains
a warmer temperature inside your firebox to make ignition
