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 re-
place, 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
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 3) You can
operate your appliance in this mode regardless of whether
you are using a remote control, wall switch or thermostat.
