General Information
The Oxford Direct Vent/Natural Vent Room Heater, Model
No. OXDV30NV, is a vented gas appliance listed to the ANSI
standard Z21.88-2009 and CSA-2.33-2009 for Vented Room
Heaters, and CSA 2.17-M91, Gas-Fired Appliances For Use
at High Altitudes.
The installation of the Oxford Direct Vent/Natural Vent Room
Heater must conform with local codes, or in the absence of lo-
cal codes, with National Fuel Gas Code, ANSI Z223.1/NFPA
54 — latest edition and CSA B-149.1 Installation Code. (EX-
CEPTION: Do not derate this appliance for altitude. Maintain
the manifold pressure at 3.5” w.c. for Natural Gas and 10.0”
w.c. for LP gas at maximum input.)
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 certied kit is used.
Installation and replacement of gas piping, gas utiliza-
tion equipment or accessories, and repair and servic-
ing of equipment shall be performed only by a qualied
agency, preferably NFI or WETT (Canada) certied. The
term “qualied agency” means any individual, rm, cor-
poration, 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 pre-
cautions required, and has complied with all the require-
ments of the authority having jurisdiction.
The Oxford Direct Vent/Natural Vent Room Heater should
be inspected before use and at least annually by a quali-
ed service agency. It is imperative that control compart-
ments, burners, and circulating air passageways of the
appliance be kept clean.
The Oxford 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 Oxford Direct Vent/Natural Vent Room Heater must be
isolated from the gas supply piping system by closing its in-
dividual 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 en-
ter 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 atmo-
sphere 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.
This appliance may be installed in an aftermarket* manufac-
tured (mobile) home, where not prohibited by state or local
codes.
WARNING: Operation of this heater when not connected
to a properly installed and maintained venting system
can result in carbon monoxide (CO) poisoning and pos-
sible death.
The Oxford 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 Na-
tional Electrical Code ANSI/NFPA 70, (latest edition), or of
the current Canadian Electrical Code C22.1.
