Mantel Clearances for Built-In
Installation
If placing custom mantel above built-in firebox,
you must meet minimum allowable clearance
between mantel shelf and top of firebox
opening shown in Figure 7. These are mini-
mum allowable mantel clearances for a safe
installation. Use larger clearances wherever
possible to minimize heating of objects and
materials placed on mantel.
CAUTION: Do not allow vent-
free gas log heater to touch or ex-
tend beyond fireplace screen.
NOTICE: Surface temperatures
of adjacent walls and mantels
become hot during operation.
Walls and mantels above firebox
may become hot to the touch.
If installed properly, these tem-
peratures meet the requirement
of the national product standard.
Follow all minimum clearances
shown in this manual.
NOTICE: If your installation does
not meet the minimum clearances
shown, you must do one of the
following:
• raise the mantel to an accept-
able height
• remove the mantel
BUILT-IN FIREBOX INSTALLATION
Built-in installation of this firebox involves
installing firebox into a framed-in enclosure.
This makes front of firebox flush with wall.
Optional brass trim accessories are available
(see Accessories, page 31). Brass trim will ex-
tend past sides of firebox approximately 1/2".
This will cover rough edges of wall opening.
If installing a mantel above firebox, you must
follow clearances shown in Figure 6, page 10.
Follow instructions below to install firebox in
this manner.
1. Frame in rough opening. Firebox framing
should be constructed of 2 x 4 lumber or
heavier. Use dimensions in Table 1 and
rough opening layout in Figure 8, page
12. Adjust framing so that firebox flushes
with finished wall surface. If installing in a
corner, use dimensions in Figures 8 and
9, page 12 for rough opening.
