Insert Leveling
At each front and rear corner of the insert is an adjustable leg provided
to level the insert should the hearth of the fireplace be uneven. To adjust
the legs, loosen the two 5/32" allen head screws, move the leg to the
desired height and then tighten the screws. Repeat these steps for each
adjusting leg.
WARNING
B-Vent appliances are not designed to operate
in negatively pressured environments (pressure
within the home is less than pressures outside).
Significant negatively pressured environments
caused by weather, home design, or other devices
may impact the operation of these appliances.
Negative pressures may result in poor flame
appearance, sooting, damage to property and/or
severe personal injury. Do not operate these
appliances in negatively pressured environments.
Providing adequate ventilation to the appliance for
combustion air will eliminate a negative pressure
environment.
