Hearth Requirements
All installations will require a hearth or floor, flush with
the bottom of the heater, to support the weight of the
cast iron plate and to ensure the removable hearth
fender rests at the proper height.
A
non-combustible
hearth is
not
required in front of this
appliance.
Floor Requirements
The 530 heater is approved for installation directly
on any combustible material
other than
soft flooring
material such as carpet or vinyl.
Mantel Requirements
The Arch Fronts series is designed to be compatible
with combustible mantels provided clearances are
maintained as indicated in the Dimensions and
Clearances, and Framing diagrams below and on the
following pages. The 549 Cast Arch requires non-
combustible cement board on the wall above. Be aware
that although safe, some combustible materials and
finishes at the listed clearances may, over time, discolor,
warp, or show cracks. Care should be taken when
choosing materials—consult your fireplace dealer.
Wall Requirements
The 549 Arched Front requires non-combustible board
applied to the front face of the framing cavity, above the
arch. See drawing on page 8 for minimum extent
of non-combustible board. Combustible wall finishes
up to 1” thickness may be applied over top of the non-
combustible board. Note the cutout in the cement board
is very specific when using 549 arch without backing
plate. Otherwise, the heater with brackets attached will
not move forward enough to meet the back of the cast
arch. If a backing plate is used, the upper corners of the
cut-out can be cut square as the backing plate will cover
the cut-out.
Casting Tolerances
Due to the nature of cast iron, dimensional consistency
may vary from one unit to the next and some variation
in surface finish and flatness is to be expected. We have
done our best to control and make allowance for this;
however some variation is inevitable.
