When installing the Q1LI with 8ft (2.44M) or more of vertical venting, either co-axial or co-linear, it may be
necessary to restrict the fresh air supply in the firebox to control the combustion and flame appearance. Using
the pair of air restrictors supplied with the unit, install them on each side of the firebox and adjust to the correct
setting as outlined in the figure and table below. To install the air restrictors first you must remove the log set,
air diffuser, and creamic brick panels (see

then remove the set screws as shown on each side of the firebox. Next, install the restrictors at the
correct setting and tighten the set screws to hold them in place.
