For ease of installation, this appliance is equipped with an approved
3"
flexible gas connector. The connector is factory-installed and can be
10 ½"
connected to the gas line as shown in figure 3.
Natural Gas requires a minimum inlet gas supply pressure of 5.5"
W.C. & a manifold pressure of 3.5" W.C. Propane Gas requires a
minimum inlet gas supply pressure of 11" W.C. & a manifold pressure
of 10" W.C. The fireplace gas connection and the main operating gas
valve is located behind the removable brass trim at the bottom of the
unit and need only be attached to the gas line with an approved fit-
ting, as required by the applicable installation codes.
• Only use gas shut-off valves approved for use by the state, province,
