HIGH ELEVATIONS

Input ratings are shown in BTU per hour and are certifi ed
without derating for elevations up to 4,500 feet (1,370
m) above sea level.
For elevations above 4,500 feet (1,370 m) in USA,
installations must be in accordance with the current
ANSI Z223.1/NFPA 54 and/or local codes having juris-
diction.
In Canada, please consult provincial and/or local authori-
ties having jurisdiction for installations at elevations
above 4,500 feet (1,370 m).

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 pro-
vides the dual benefi t of an economical and environmentally
responsible product and one which lights easily even in
FP3011
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 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.
To 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
