The Jefferson Direct Vent/Natural Vent Room Heater, Model Nos. 2820, 2822, 2823, 2825, 2827 and 2828, is a vented gas appliance listed to the ANSI Standard Z21.88b- 2001 and CSA-2.33b-2001 for Vented Room Heaters, and CSA 2.17-M91, Gas-Fired Appliances For Use at High Alti- tudes.
The installation of the Jefferson Direct Vent/Natural Vent Room Heater must conform with local codes, or in the ab- sence of local codes, with National Fuel Gas Code, ANSI Z223.1 Ñ latest edition and CSA B-149.1 Installation Code. (EXCEPTION: Do not derate this appliance for altitude. Maintain the manifold pressure at 3.5 inches w.c. for Natu- ral Gas and 10 inches w.c. for LP gas at maximum input.)
This appliance is only for use with the type of gas indi- cated 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 Jefferson 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 Jefferson 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 Jefferson Direct Vent/Natural Vent Room Heater must be isolated from the gas supply piping system by clos- ing 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.
'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 sys- tem 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 combus- tion and vent the exhaust vertically through the roof to the atmosphere.
This appliance is approved for bedroom installations in the U.S. and Canada.
This appliance may be installed in an aftermarket* manufactured (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 Jefferson 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 draperies.
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.
Clothing or other flammable materials should not be placed on or near the appliance.
Any safety screen, glass or guard removed for servicing an appliance must be replaced prior to operating the appliance.
The appliance area must be kept clear and free from combustible materials, gasoline, and other flammable vapors and liquids.
