• Never obstruct the front opening of the vent-free firebox
or restrict the flow of combustion and ventilation air.
• Minimize modifications to existing construction. Refer
to Figure 3 for location suggestions.
• Do not install in the vicinity where gasoline or other
flammable liquids may be stored. The vent-free firebox
must be kept clear and free from these combustible
materials.
