6"
(150mm)
Hearth Requirements
The Radiance Heater must be installed on rigid floor-
ing. When the heater is installed directly on any
combustible surface other than wood flooring, a metal
or wood panel extending the full width and depth of the
unit must be used as the hearth. There are no other
hearth requirements.
WARNING:
• Always maintain required
clearances (air spaces) to nearby combustibles
to prevent fire hazard. Do not fill air spaces with
insulation. All venting components must
maintain a 1" (25mm) clearance to combustible
materials. Maintain a 6” (150mm) clearance
when using single wall pipe.
• The gas appliance and vent system must be
vented directly to the outside of the building
and never be attached to a chimney serving a
separate solid fuel or gas-burning appliance.
• Refer to the manufacturer's instructions
included with the venting system for complete
installation procedures.
The installation must conform with local codes or, in
the absence of local codes, with the National Fuel
Gas Code, ANSI Z223.1 - latest edition.
(EXCEPTION: Do not derate this appliance for
altitude. Maintain the manifold pressure at 3.5” w.c.
for Natural Gas and 10” w.c. for Propane.)
High Elevations
Input ratings are shown in BTU per hour and are
certified without deration for elevations up to
4,500 feet (1,370m) above sea level.
For elevations above 4,500 feet (1,370m) in USA,
installations must be in accordance with the
current ANSI Z223.1/NFPA 54 and/or local codes
having jurisdiction.
In Canada, please consult provincial and/or local
authorities having jurisdiction for installations at
elevations above 4,500 feet (1,370m).
WARNING: Improper installation, adjustment, alteration, service or maintenance can
cause injury or property damage. Refer to
this manual for correct installation and
operational procedures. For assistance or
additional information consult a qualified
installer, service agency, or the gas supplier.
Venting Requirements and Options
The Radiance must be properly connected to a listed
4” (102mm) Type B venting system or to an approved
Class A masonry or factory-built chimney system. In
Canada, a complete relining of Class A chimney
systems is required.
The Radiance Natural Vent stove will accept decorative
6” (150mm) stove pipe around the Type B venting
system, for aesthetic purposes.
Complete Type B vent systems are available from a
number of manufacturers, and your dealer can usually
supply one. Pipe sections from different makers are not
interchangeable; do not mix pipe or vent sections from
different makers. Follow the vent system
manufacturer’s instructions exactly.
Decorative stove chimneys for B vent applications are
available through vent dealers.
The vent system should conform to specifications of
the National Fuel Gas Code, latest edition.
If connecting to a Class A chimney system, use 4”
(102mm) single wall or 4” Type B vent connector.
Single wall vent connector requires a minimum 6”
(153mm) clearance to combustible surfaces.
Exterior chimneys may be subject to flow reversal or
condensation. To lessen these conditions, enclose
Type B vents in an insulated chase, or reline exterior
Class A chimneys.
An approved pass-through device is always required,
whether the vent system passes through a wall or a
ceiling. Use a pass-through device from the same
maker who supplies the venting system.
Venting terminals shall not be recessed into a wall or
siding.
Vent Layout and Height Requirements
Venting for a Radiance can rise vertically through the
home, or can pass through an exterior wall and rise
along the outside of the home. Some codes require
that a Type B vent system rising on the outside of the
home be enclosed in a chase. Check your local codes
for requirements.
The minimum vent system height for the Radiance
Natural Vent Stove is 8 feet (2.43m), (Fig. 7) measured
from the top of the stove. To determine the minimum
height the vent system must extend through or past the
roof, refer to the 1993 edition of the National Fuel Gas
Code.

Passing Through a
Combustible Wall or Ceiling
An approved pass-through device is always required
when a vent passes through a combustible wall or
ceiling. Check with the maker of the vent system for
the correct listed devices that are available. A listed
pass-through device is required whether or not the
installation includes decorative pipe around the Type B
venting system. NOTE: It is essential to seal between
the ceiling support (sometimes called a ‘firestop
spacer’) and the decorative pipe, if installed, with a
high-temperature silicone sealant. (Fig. 6)
