Table 2 Various Mantel Depths and Corresponding Installation Heights
No combustible mantel can be installed lower than 15 ½" above the top of the firebox opening. A combustible
mantel cannot be wider than 12".
For combustible mantel depths not mentioned in the list above, you can interpolate the minimum installation
height between the two closest mantel depths. For example:
•
Mantel depth to be installed: 9 ¼"
•
It is between 8" and 10" with corresponding installation heights of 20" and 25 ½"
•
So: ((9.25 – 8) / (10-8) x (25.5-20))+20 = 23.4375 = 23 7/16"
•
Minimum installation height of a 9 ¼" mantel: 23 7/16" above the firebox opening.
If the combustible mantel has a cross-section with variable depth, it has to be installed so that its widest part is
not installed lower than the corresponding minimum installation height while making sure that the lowest point
of the mantel is not installed lower the minimum installation height corresponding to it depth.
Refer to the "Installation: Mantel" section for particulars.

OPERATION

AIR CONTROLS

All the TOPAZ air controls are located behind the right extrusion
(see Figure 2 and Figure 3).
Combustion Air Control
Unlike most open fireplaces, RSF fireplaces don't have flue
dampers. Instead, the system is sealed by closing the door, and the
amount of air entering the firebox is controlled by the combustion
air control lever (see Figure 2 and Figure 3) which can be moved
left or right. Setting the air control lever all the way open (towards
the right) will allow the maximum amount of air into the firebox.
Closing the air control (towards the left) will reduce the amount of
air entering the firebox.
Outside Air Control
The TOPAZ is designed to use outside air for combustion (see
Figure 2 and Figure 3).
Pulling chain as much as possible and locking it in place by
wedging it through the slot will completely open the outside air
damper and allow fresh air into the base of the fireplace. Because
outside air is generally colder and denser it will help to start the fire.
In some cases this fresh air will also help compensate for negative
pressure problems within the house; however it will not prevent the
fireplace from smoking in a severely depressurized house.
We recommend always using outside air for combustion but you
