When installing the double outlet system, the hot air outlets can be installed in the same room as the fireplace, or one or both of the outlets can be installed in adjacent or upper rooms. Installing the ducts at different elevations will tend to exhaust more heat out of the higher outlet (Figure 17).

WARNING: The outlet

 

grills should not be

The duct system must be installed respecting the following:

1.Remove the plates closing up the 8” dia. holes on top of the fireplace. Then, cut the insulation in order to obtain two 8” dia. openings. Fix the adaptors on the fireplace openings by turning clockwise (Figure 16).

2.Maintain at least a 2” (50 mm) clearance between the ducts and any combustible material; the required hole size is 13” x 13” (330 mm x 330 mm).

Exception #1: For the grills, the framing can be 10-3/4” x 10- 3/4” (275 mm x 275 mm) to provide the clearance as required by the integral spacers on the double outlet duct system.

3.The maximum number of elbows in a run of duct is two.

4.Maintain at least 6-1/2” (160 mm) clearance from the outlet grill framing to a combustible ceiling, side wall or mantel.

5.When traversing a combustible wall or floor, a firestop must be installed at the wall or floor penetration. The hole size must be 13” x 13” (330 mm x 330 mm)

6.Do not connect the hot air ducts to a central heating system. Malfunc- tion of the heating system’s blower will cause the fireplace to overheat. A furnace duct is only single wall and not double wall as is required for the Montecito Estate™ hot air exhaust.

7.Use only Security Chimneys International grills and components as described in this manual. Other grills or registers may be too restric- tive and may overheat the fireplace or ceiling.

8.Do not use insulated flexible ducts as they will overheat.

9.Do not use tees or any other components than the ones specifically listed here.

10.Never allow the ducting to pitch down as hot air will be trapped creat- ing a fire hazard. Never route the ducting downwards.

11.The hot air outlet grills must be installed with the louvers pointing downwards in order to prevent overheating adjacent ceilings.
