The Radiance Direct Vent/Natural Vent Room Heater,
Model Nos. 3350 thru 3354, 3360 thru 3369 and 3390 thru
3399, is a vented gas appliance listed to the ANSI standard
Z21.88b-2002 and CSA-2.33b-2002 for Vented Room Heaters, and CSA 2.17-M91, Gas-Fired Appliances For Use at
High Altitudes.
The installation of the Radiance Direct Vent/Natural Vent
Room Heater must conform with local codes, or in the absence
of local codes, with National Fuel Gas Code, ANSI Z223.1
— latest edition and CSA B-149.1 Installation Code. (EXCEP
TION: Do not derate this appliance for altitude. Maintain the
manifold pressure at 3.5 inches w.c. for Natural Gas and 10
inches w.c. for LP gas at maximum input.) Refer to Page 30
(RF only).
This appliance is only for use with the type of gas indicated
on the rating plate. This appliance is not convertible for use
with other gases unless a certified kit is used.
Installation and replacement of gas piping, gas utilization equipment or accessories, and repair and servicing of
equipment shall be performed only by a qualified agency.
The term “qualified agency” means any individual, firm,
corporation, or company that either in person or through
a representative is engaged in and is responsible for (a)
installation or replacement of gas piping, or (b), the connection, installation, repair, or servicing of equipment, who
is experienced in such work, familiar with all precautions
required, and has complied with all the requirements of
the authority having jurisdiction.
The Radiance Direct Vent/Natural Vent Room Heater
should be inspected before use and at least annually by
a qualified service agency. It is imperative that control
compartments, burners, and circulating air passageways
of the appliance be kept clean.
The Radiance Direct Vent/Natural Vent Room Heater and
its individual shut-off valve must be disconnected from the gas
supply piping during any pressure testing of that system at test
pressures in excess of 1/2 psig (3.5 kPa).
The Radiance Direct Vent/Natural Vent Room Heater must
be isolated from the gas supply piping system by closing its
individual manual shutoff valve during any pressure testing
of the gas supply piping system at test pressures equal to or
less than 1/2 psig.
An accessible tap is located above the pilot/On-Off knob
for checking the inlet pressure.
‘Direct Vent’ describes a sealed combustion system in which
incoming outside air for combustion and outgoing exhaust enter
and exit through two separate concentric passages within the
same sealed vent system. The system does not use room air
to support combustion. The Direct Vent system permits the
gas appliance to be vented directly to the outside atmosphere
through the side of the house or vertically through the roof.
Conventional venting systems (Natural Vent) take air from the
room for combustion and vent the exhaust vertically through
the roof to the atmosphere.
This appliance is approved for bedroom installations in
the U.S. and Canada. Check local codes for natural vent
requirements.
This appliance may be installed in an aftermarket* manu
20004188

Vent Termination Clearances
When planning the installation, consider the location
of the vent terminal and clearances. Some of the most
common clearances to keep in mind are shown in Figure 9.
Important: All vent clearances must be maintained.
Check your vent termination clearances against
Figures 9 through 11.
The vent should be placed so that people cannot be
burned by accidentally touching the vent surfaces when
the stove is operating.
The vent termination should be located where it cannot
be damaged by such things as automobile doors, lawn
mowers or snowblowers and it should be located away
from areas where it could become blocked by snow,
etc.
Some considerations are:
• Obstructions or impediments to venting.
• Nearby combustible materials that could come into
contact with combustion exhaust gases.
• Other nearby openings {within 12” (305mm)} through
which exhaust gas could reenter the building.
• All vegetation within 3’ (76mm) that may interfere with
the draft.
Other factors that influence where the installation will
be sited include the location of outside walls, where
additional heat may be desired in the home, where the
family members gather most regularly, and perhaps
most importantly, the distance limitations of the venting
system.
IMPORTANT
Direct Vent Only
• The horizontal termination must not be recessed
into the exterior wall or siding.
• Horizontal vent runs must be level toward the
vent termination.
• Clearances around the vent termination must be
maintained.
•For installations using Simpson DuraVent pipe,
parallel installations with minimum wall clearance
have restricted access for connecting the Horizontal Vent Cap straps to the vent pipe. See the
maker’s instructions for recommended installation procedures.
ST132a
20004188
Radiance Direct Vent /Natural Vent Gas Heater
Vent Termination Clearances
Your stove is approved to be vented either through the
side wall, or vertical through the roof.
• CFM Specialty Home Products does not require
any opening for inspection of vent pipe.
• Only CFM Corporation and Simpson DuraVent
venting components specifically approved and
labelled for this stove may be used.
• Minimum clearances between vent pipes and
combustible materials is one (1”) inch (25 mm),
except where stated otherwise.
• Venting terminals shall not be recessed into a wall or
siding.
• Horizontal venting must be installed on a level plane
without an inclining or declining slope.
There must not be any obstruction such as bushes,
garden sheds, fences, decks or utility buildings within
24” from the front of the termination hood.
Do not locate termination hood where excessive snow
or ice build up may occur. Be sure to check vent termination area after snow falls, and clear to prevent accidental blockage of venting system. When using snow
blowers, make sure snow is not directed towards vent
termination area.
Location of Vent Termination
It is imperative the vent termination be located observing the minimum clearances as shown on this page.
