OPERATION
Once your Green Mountain Insert 70 is installed, you
are ready to light a fire.
Every installation, season’s firewood, and operator’s
technique varies. Learn how to use your fireplace
insert most efficiently for your installation. We can
give you the basic principles, but only you can
ensure maximizing the potential of your fireplace
insert while also operating it safely.
WARNING: HOT WHILE IN OPERATION! KEEP
CHILDREN, PETS, CLOTHING AND FURNITURE
AWAY. CONTACT MAY CAUSE SKIN BURNS.
Read this entire chapter before lighting your first fire.
It explains the controls and features of your wood
fireplace insert, how to choose firewood, and how to
use your fireplace insert on a daily basis.

Before lighting any fires,
become familiar with the
location and operation of your fireplace insert's
controls and features and learn how to use them
(
See Figure 24
). For your own safety, do not modify
these features in any way. We recommend you use
fireplace gloves when the fireplace insert is in
operation and hot.
Figure 21 - Controls & Features
FRONT DOOR HANDLE:
The firebox door allows
you to load wood into your fireplace insert; a wood
handle operates the door. To open the door, pull up
on the handle and swing the door away from the
fireplace insert. To latch the door, push the door
tightly towards the firebox then continue to push the
handle in and down until it latches shut. Gently pull
on the door handle to make sure it is properly
latched.
PRIMARY AIR CONTROL:
The primary air control
lever is located under the ash lip. The primary air
control allows you to regulate the amount of air
entering the firebox. Generally, the more air allowed
into the firebox, the faster the rate of burn and the
higher the heat output. Conversely, less air creates
a slower burn, with lower heat output. For maximum
airflow, pull the lever left as far as possible; move
the lever right as far as possible for minimum airflow
(does not close completely).

PERATION
A blower is already installed on this insert. It is
located underneath the insert, behind the front
casting. Its function is to increase airflow through
the heat exchanger and improve hot air circulation in
the room. When used regularly, the blower can
provide a small increase in efficiency, up to 2%.
However, the use of a blower should not be used as
a way to gain more output from an insert that is
undersized for the space it is intended to heat.
Ensure the blower cord is not in contact with any
surface of the insert to prevent electrical shock
or fire damage. Do not run cord beneath the
insert.
Alow the insert to reach operating temperature
(approximately one hour) before turning on the
blower, since increased airflow from the blower will
remove heat and affect the start up combustion
efficiency.
