Masonry and other non-combustible mantels (shelf and posts) can be placed anywhere
around the fireplace opening.
For combustible mantels (shelf and posts), please see Table 1 (J-K-L-M) for the
maximum depth of the mantel shelf and posts and their installation clearance
requirements. See Figure 2 for an example.
The only combustible material accepted on the facing of the fireplace is for a mantel
(shelf and posts).
If you need to attach the mantel to the front of the fireplace refer to page 28 to know
where screws are permitted on the front of the fireplace facing.

NSTALLATION
The firebox lining of the RUMFORD 1500 fireplace is packaged separately from the
fireplace. You must make sure that all is properly installed inside the firebox before
making your first fire. This is easily accomplished by following the instructions provided
with the lining option you have chosen:
• EO-VP-1500 for the Vermiculite panels with a herringbone brick,
•
EO-RB1500 for the Cement refractory bricks with a running bond brick pattern.
The lining installation instructions can also be found on our website at
www.renaissancefireplaces.com
WARNING: THE FIREPLACE SHOULD NEVER BE BURNED WITHOUT THE FIREBOX
INSULATION AND LINING PROPERLY INSTALLED.

NFORMATION
The primary design criteria for Renaissance fireplaces was ultra-low emissions and the
Renaissance team incorporated a wide range of materials and design factors to enable
Renaissance Rumford fireplaces to burn more cleanly than any other open fireplaces.
One of the most important of these factors is the vermiculite firebox lining material.
Our research to date has found that using conventional high temperature firebrick
results in much higher emissions and reduced efficiency. Vermiculite refractory panels,
although much more expensive, is lightweight, insulating and reflective, which results in
a hotter fire faster; reducing emissions and improving efficiency.
Vermiculite is not a new material, it has been used for lining the fireboxes of solid
fuelled boilers, furnaces, stoves and fireplaces in Europe for over 20 years and remains
one of the most popular firebox lining materials where low emissions are a design
criteria. Its long history of reliable performance and excellent durability is one of the
primary reasons we selected vermiculite panels for the Renaissance.
Although the vermiculite panel surface is quite durable, impact from loading logs in the
fireplace can be sufficient to mark the material somewhat. These marks are strictly
cosmetic and most people do not find them objectionable. With normal use it is also
common for some portions of the vermiculite surface to change color, from beige to
orange. This discoloration is the result of variable heating of the panels. It is permanent
but strictly cosmetic; it does not affect durability. Unlike conventional firebrick which
turns black over time from the accumulation of creosote on the bricks the high
combustion temperatures in the Renaissance will burn the creosote when the unit is
operated with the door closed resulting in clean firebox walls with no black deposits.
