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 Heat-
ers, 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 utiliza-
tion 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 con-
nection, 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
-
factured (mobile) home, where not prohibited by state or local
codes.

-
nected to a properly installed and maintained venting
system can result in carbon monoxide (CO) poisoning
