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 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.
WARNING: Operation of this heater when not con- nected to a properly installed and maintained venting system can result in carbon monoxide (CO) poisoning and possible death.
The Radiance Direct Vent/Natural Vent Room Heater, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code ANSI/NFPA 70, (latest edition), or of the current Canadian Electrical Code C22.1.
Due to high temperatures this appliance should be located out of traffic and away from furniture and draper- ies.
WARNING: This appliance is hot while in operation. Keep children, clothing, and furniture away. Contact may cause burns or ignition of combustible materials.
Children and adults should be alerted to the hazards of high surface temperatures and should stay away to avoid burns or clothing ignition. Young children should be carefully supervised when they are in the same room as the appliance.

This gas appliance must not be connected to a chimney flue serving a separate solid-fuel burning appliance.
CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.
Verify proper operation after servicing.
