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.
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.

Dimensions & Clearances — 539 and 550 Arch fronts (539 Windsor Arch shown here)
Mantel Requirements
The Arch Fronts series is designed to install with
combustible mantels provided clearances are
maintained as indicated in the Dimensions and
Clearances, and Framing diagrams below and on the
following pages. The 539 and the 550 back plate may
also be installed without a mantel provided listed
clearances are maintained. 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.
