If the appliance is installed on any combustible surface other than wood flooring, such as carpet or tile, a metal or wood panel must be installed to extend the full length and width of the unit. WARNING • • • • Do not install this heater in a bathroom or bedroom. Installation of this heater must conform with Local Codes or in the absence of Local Codes, with the National Fuel Gas Code, ANSI Z223.1. This heater creates warm air currents. These currents move heat to wall surfaces next to the heater. Installing the heater next to vinyl or cloth wall coverings or operating the heater where impurities in the air such as tobacco smoke exist, may discolor walls. Do not use a blower insert, heat exchanger insert or other accessory not approved with this heater. Vermont Castings Jefferson Vent Free Gas Heater Gas Specifications Max. Input BTU/h Min.

(EXCEPTION: Do not derate this appliance for altitude up to 4,500 feet (1,370m). Maintain the manifold pressure at 3.5” w.c. for Natural Gas and 11.0” w.c. for LP Gas. This appliance may be installed in an aftermarket* manufactured (mobile) home, where not prohibited by state or local codes. This appliance is to be used only with the type of gas specified on the rating plate which is attached to the rear panel. This appliance is not convertible for use with other gases. *Aftermarket: Completion of sale, not for purpose of resale, from the manufacturer. High Elevations Input ratings are shown in BTU per hour and are certified without deration from elevations up to 4,500 feet (1,370m) above sea level. Nuisance outages may occur at altitudes above 4,500 feet (1,370m) if dirt, dust, lint and/or cob- webs are allowed to accumulate on burner and/or ODS pilot. Monthly inspection and cleaning is recommended for altitudes above 4,500 feet (1,370m) For elevations above 4,500 feet (1,370m), installa- tions must be in accordance with the current ANSI Z223.1 and/or local codes having jurisdic- tion. 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. Odor During Operation Neither natural gas nor propane gas give off an odor when burned. The nature of a vent free combustion system, however, is such that odors may occasion- ally be produced during heater operation when impurities exist in the immediate area. Cleaning solutions, paint, solvents, cigarette smoke, candles, adhesives, new carpet or textiles, etc., all can create fumes. These fumes may mix with combustion air and can create odor. Such odors will disappear over time, however the condition can be alleviated by opening a window or otherwise providing additional ventilation to the area. Vermont Castings Jefferson Vent Free Gas Heater Vent Free Features The JUVS Gas Heater is an unvented gas appliance tested and listed to the ANSI standard Z21.11.2a.2001. The Vent Free Gas Heater is configured to use Natural Gas, (JUVSRN, JUVSMN ) or Propane (JUVSRP, JUVSMP). Because these heaters are clean-burning and highly energy-efficient, no venting system is required. The JUVS is shipped fully assembled with the exception of the log set. The log set is assembled during installation. The JUVS is equipped with a Honeywell control valve that allows thermostatic control, on/off switch or a remote switch (not supplied). The JUVS model incorporates variable regulators that allow you to adjust burner heat output between HIGH, (28,000 BTU), and LOW, (20,000 BTU). See the Operation Section for details. The standing pilot incorporates an Oxygen Depletion System (ODS/pilot) which shuts off gas flow to the burner in the event that sufficient fresh air becomes unavailable for continued safe operation. WARNING This heater must have fresh air for proper opera- tion. If it does n...
