1. “MANUAL” Mode: When used in this mode, your pellet fire is controlled from the control panel only. When the
pellet fire is in the “MANUAL” mode, the pellet fire will not respond to any external switch (i.e. thermostat).
The pellet fire will automatically light itself when it is first turned on. When the “HEAT SELECT” light comes
on, choose the heat setting you want to operate the pellet fire at. The pellet fire will continue to operate at this
heat setting until you decide to change it or want to turn the pellet fire off (by pressing the ON/OFF button).
2. “HIGH/LOW” Mode: With the switch in this position, your pellet fire will alternate from a factory preset low
level to the setting you have chosen with the “HEAT SELECT” button (see “HEAT SELECT: Button” section
for more information). This mode is almost exclusively used with an externally wired switch and is highly
recommended since it can create substantial fuel savings. The pellet fire will automatically light itself when it
is first turned on. When the thermostat senses that heat is required, the pellet fire will operate at the setting
you have chosen with the “HEAT SELECT” button. When the thermostat is satisfied, the pellet fire goes down
to the factory preset low level.
3. “AUTO” Mode: With the switch in this position, your pellet fire will turn itself on and off based on an externally
wired switch. The most common use of this mode is a programmable or non-programmable wall thermostat.
When wired to a thermostat, the pellet fire will automatically light itself when the thermostat senses that heat
is required and will automatically turn itself off when the thermostat is satisfied. This mode can also be used
with a wall switch or remote controls. Consult your local dealer or visit WWW.METROFIRES.CO.NZ for more
information on available options.
“ON/OFF” Button
This button allows you to turn the pellet fire on and off. Once pressed, the pellet fire will go through a start-up
sequence and the ON/OFF light will blink. During this time, the feed rate is preset and the “HEAT SELECT” button
is disabled. Once the pellet fire is warm enough, the “ON/OFF” light will stop blinking and you will be able to
change the heat setting with the “HEAT SELECT” button.
“HEAT SELECT” Button & Bar Graph
There are 5 possible heat settings for your
pellet fire. Each setting is indicated in the
bar graph; 1 being the lowest, 5 being the
highest. Pressing the “HEAT SELECT” button
will change the heat setting as indicated
in the bar graph. Each time the button is
pressed, your pellet fire will go to the next higher heat level (from 1 to 2, 2 to 3 etc...). Once the heat level reaches
the highest setting (5) and the “HEAT SELECT” button is pressed again, the heat level will return to the low setting
(1). Please note that during the start-up period, the “HEAT SELECT” button is disabled. At some point during the
start-up period, you will be able to set the heat level but the pellet fire will not operate at the desired setting until it
