cal codes, with National Fuel Gas Code, ANSI Z223.1/NFPA
54 — latest edition and CSA B-149.1 Installation Code. (EX-

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.
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).

‘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.
The Oxford Direct Vent/Natural Vent Room Heater, when in-
stalled, must be electrically grounded in accordance with lo-
cal codes or, in the absence of local codes, with the National
Electrical Code ANSI/NFPA 70, (latest edition), or of the cur-
rent Canadian Electrical Code C22.1.
Fuels used in gas, woodburning or
oil red appliances, and the products of combustion of such
fuels, contain chemicals known to the State of California to
cause cancer, birth defects and other reproductive harm.
