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

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
