gases unless a certified kit is used.
Installation and replacement of gas piping, gas utilization
equipment or accessories, and repair and servicing of equip
-
ment shall be performed only by a qualified agency, preferably
NFI or WETT (Canada) certified. 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 servic
-

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 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 com-
bustion 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* manufactured
(mobile) home, where not prohibited by state or local codes.
