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 lo­cal codes, with National Fuel Gas Code, ANSI Z223.1/NFPA
54 — latest edition and CSA B-149.1 Installation Code. (EX­CEPTION: 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 certied 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 qualied
agency, preferably NFI or WETT (Canada) certied. The
term “qualied 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 con­nection, installation, repair, or servicing of equipment,
who is experienced in such work, familiar with all pre­cautions required, and has complied with all the require­ments 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 compart­ments, 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 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 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 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* manufac­tured (mobile) home, where not prohibited by state or local
codes.

Vent Termination Clearances

When planning the installation, consider the location of
the vent terminal and clearances. Some of the most com­mon clearances to keep in mind are shown in Figure 10.

Important: All vent clearances must be maintained.
Check your vent termination clearances against Fig­ures 9 through 11.

The vent should be placed so that people cannot be
burned by accidentally touching the vent surfaces when
the stove is operating.

The vent termination should be located where it cannot be
damaged by such things as automobile doors, lawn mow­ers or snowblowers and it should be located away from
areas where it could become blocked by snow, etc.

Some considerations are:

• Obstructions or impediments to venting.

• Nearby combustible materials that could come into
contact with combustion exhaust gases.

• Other nearby openings {within 12” (305 mm)} through
which exhaust gas could reenter the building.

• All vegetation within 3’ (76 mm) that may interfere with
the draft.

Other factors that inuence where the installation will be

sited include the location of outside walls, where addi­tional heat may be desired in the home, where the family
members gather most regularly, and perhaps most impor­tantly, the distance limitations of the venting system.

IMPORTANT

Direct Vent Only

• The horizontal termination must not be recessed
into the exterior wall or siding.

• Horizontal vent runs must be level toward the vent
termination.

• Clearances around the vent termination must be
maintained.

• For installations using Simpson DuraVent pipe, par­allel installations with minimum wall clearance have
restricted access for connecting the Horizontal Vent
Cap straps to the vent pipe. See the maker’s instruc­tions for recommended installation procedures.

Oxford Direct Vent / Natural Vent Gas Heater

Venting Termination Clearances

Your stove is approved to be vented either through the
side wall, or vertical through the roof.

• This unit does not require any opening for inspec-

tion of vent pipe.

• Only Vermont Castings Group and Duravent vent-

ing components specically approved and labelled
for this stove may be used.

• Minimum clearances between vent pipes and com-

bustible materials is one (1”) inch (25 mm), except
where stated otherwise.

• Venting terminals shall not be recessed into a wall or
siding.

• Horizontal venting must be installed on a level plane
without an inclining or declining slope.

There must not be any obstruction such as bushes, gar­den sheds, fences, decks or utility buildings within 24”
from the front of the termination hood.

Do not locate termination hood where excessive snow or
ice build up may occur. Be sure to check vent termina­tion area after snow falls, and clear to prevent accidental
blockage of venting system. When using snow blowers,
make sure snow is not directed towards vent termination
area.

Location of Vent Termination

It is imperative the vent termination be located observing
the minimum clearances as shown on this page.

Assembly, connected by a cable. (Fig. 12) The Blower
Assembly mounts to the bottom rear of the stove, and
the Rheostat mounts to the valve coverplate. The as­sembly includes a ‘snapstat’ which automatically turns
the fan On (or Off) above (or below) approximately
109°. The Rheostat also provides a range of fan speed
settings from Off (which overrides the snapstat func­tion) to High. Unpack and inspect the Blower assem-

bly. Conrm that the fan spins freely.

WARNING

This appliance is equipped with a three-prong (ground­ed) plug for your protection against shock hazard and
should be plugged directly into a properly grounded
three-prong receptacle. Do not cut or remove the
grounding prong from this plug.

• Remove retaining nut from shaft of rheostat. (if pre-

installed)

• Insert the rheostat through the hole in the back of

the left side of the valve bracket, aligning the locator
pin with the smaller hole in that bracket.

General Information

The heater is shipped from the factory as a Direct Vent
Heater. It may be converted to a Natural Vent heater by
installing the Model FSDHAG Draft Hood Adapter.

The heater is approved for installation as a Natural Vent.
Vermont Castings Group Direct Vent pipe could be used
directly after the Draft Hood Adapter up to the ceiling,
then B-vent pipe must be used. Do not mix types of B­vent pipe; use components from one maker or the other.
Follow the vent component maker’s instructions exactly.
The heater will also accept standard or enamelled 7” (150
mm) diameter pipe, around the Type B venting, for deco­rative purposes only. (Fig. 32)

NOTE: The restrictor plate supplied with the stove is
not used for Natural Vent applications.

The stove, when installed as a Natural vent heater, in­cludes a vent safety switch. (Fig. 63, Page 32) Operating
the stove when it is not connected to a properly installed
and maintained venting system, or tampering with or dis­connecting the vent safety switch, can result in carbon
monoxide (CO) poisoning and possible death.

For U.S. installations: The venting system must conform
with local codes and/or the current National Fuel Gas
Code, ANSI Z22.1.

For Canadian installations: The venting system must
conform to the current CSA B149.1 installation code.

Install the Vent Pipe

Apply a bead of sealant around bottom end of inner start­er pipe (found in bag with logset) and attach to stove. Ap­ply a bead of sealant around top of inner starter pipe and
install the FSDHAG Draft Hood according to Draft Hood
instructions. (Fig. 33)

CEMENT

Attach the rst section of venting to the draft hood. De­pending on the length of the individual venting sections
and the lengths of the decorative pipe (if installed), you
may need to slip the decorative pipe over the venting sec­tions before attaching upper sections to lower ones. The
sections of decorative pipe should be oriented with their
seams (if any) toward the wall; sections usually do not
need to be fastened at each joint, other than slip sections.
If the layout includes a slip section, this should be the last
section of pipe visible in the room, at the ceiling. Complete
the venting according to the vent maker’s instructions.

D. Defective automatic valve opera-

tor

A. Pilot ame may be too low or

blowing (high) causing the pilot
safety to drop out

B. Possible blockage of the vent

terminal

Corrective Action

Using a match, light pilot. If pilot lights, turn off pilot and
push the red button again. If pilot will not light - check
gap at electrode and pilot-should be 1/8” to have a strong
spark.

With the control knob in the pilot position, push the control
knob all the way and hold. Check for spark at electrode
and pilot. If no spark to pilot, and electrode wire is properly
connected, replace the battery in the ignitor module and
try again. Refer to Maintenance Section. If the problem
still exists, replace the ignitor module box.

Check pilot ame. Must impinge on thermocouple/ther­mopile. NOTE: This pilot burner assembly utilizes both
a thermocouple and a thermopile. The thermocouple
operates the main valve operation (On and Off). Clean

and or adjust pilot for maximum ame impingement on

thermopile and thermocouple.

Turn valve knob to “Pilot”. Maintain ow to pilot; millivolt

meter should read greater than 10mV. If the reading is
okay and the pilot does not stay on, replace the gas valve.
NOTE: An interrupter block (not supplied) must be used
to conduct this test.

Check wall switch and wires for proper connections.
Jumper wire across terminals at wall switch, if burner
comes on, replace defective wall switch.. If okay, jumper
wires across wall switch wires at valve, if burner comes
on, wires are faulty or connections are bad.

1. Be sure wire connections form thermopile at gas valve
terminals are tight and thermopile is fully inserted into
pilot bracket.

2. One of the wall switch wires may be grounded. Re­move wall switch wires form valve terminals if pilot
now stays lit, trace wall switch wiring for ground. May

be grounded to replace or gas supply.

3. Check thermopile with millivolt meter. Take reading
at thermopile terminals of gas valve. Should read
250-300 millivolts (minimum 150) while holding valve
knob depressed in pilot position and wall switch “Off”.

Replace faulty thermopile if reading is below specied

minimum.

Check burner orices for debris and remove.

Turn valve knob to “On”, place wall switch to “On” millivolt
meter should read greater than 150mV. If the reading is
okay and the burner does not come on, replace the gas
valve.

Clean and/or adjust pilot ame for maximum ame im­pingement on thermopile and thermocouple.

Check the vent terminal for blockage (recycling the ue

gases).

Maintenance

Your gas heater will provide years of service with minimal
upkeep. The following procedures will help ensure that
your stove continues to function properly.

Annual System Inspection

Have the entire heater and venting system inspected an-

nually by a qualied gas technician. Replace any worn or

broken parts.

Logset and Burner /

Cleaning and Inspection

Cleanliness is critical to the proper function of the heater.
The logset and burner must all be kept free of dust and
unobstructed by debris. Inspect these areas before each
use and clean as necessary.

1. Turn the burner OFF and let the heater cool completely
before cleaning.

2. Remove the safety barrier by pulling out, then up.

3. Lift the stove front up and then swing the bottom out to
disengage it from the heater shell. (Fig. 58)

4. Carefully remove the glass and frame assembly and

place it out of the way on a at, padded surface such

as a counter protected by a towel.

CAUTION

TURN THE PILOT OFF BEFORE PAINTING. ALLOW
THE HEATER TO COOL COMPLETELY BEFORE
PAINTING.

6. Use a soft bristled brush to sweep dust or debris from
the Logs, Pilot and Burner. Use care as the logs are
fragile and susceptible to damage. DO NOT USE A

VACUUM TO CLEAN THE LOGS OR BURNER.

7. Replace the glass panel and frame assembly.

8. Replace the Stove Front.

Care of Cast Iron

An occasional dusting with a dry rag will help keep the
painted surfaces looking new. Use high-temperature
stove paints, available through your local dealer, to touch­up areas as needed. Clean areas to be painted with a
wire brush and be sure to cover the logs, burner and valve
assembly, glass and frame assembly. Apply the paint
sparingly; two light coats of paint will give better results
than a single heavy coat.

Clean porcelain enamel surfaces with a soft, damp cloth.
Do not use abrasive cleaning agents. If necessary, use
only a cleaning agent formulated especially for use on
porcelain enamel surfaces.

Fig. 58 Remove the stove front.

5. Carefully inspect the Logs for damage. Contact your
local dealer if any damage is evident. DO NOT OPER-

ATE THE HEATER WITH DAMAGED LOGS.

30

Cleaning the Glass

WARNING: Allow the glass cool completely

before attempting to clean.

It will be necessary to clean the glass periodically. During
start-up, condensation, which is normal, forms on the in­side of the glass and causes lint, dust and other airborne
particles to cling to the glass surface. Also initial paint
curing may deposit a slight lm on the glass. It is there­fore recommended that the glass be cleaned two or three
times with a non-ammonia household cleaner and warm

water (we recommend gas replace glass cleaner). After

that the glass should be cleaned two or three times during
each heating season depending on the circumstances
present.

Clean glass after rst two weeks of operation.

20306762

Oxford Direct Vent / Natural Vent Gas Heater

Glass Replacement

Replace glass only with Vermont Castings Group ap­proved parts. Refer to Page 33 for Replacement Parts.
Refer to Figure 59 and previous instructions for removal
of the damaged glass frame.

Fig. 59 Release the latches to release the glass frame.

Gasket Replacement

The heater uses a ‘tadpole’ type gasket to seal between
the glass panel and the frame. In time, this gasket can
become brittle and compressed and should be replaced.
New gasket is available from your dealer.

Shut off the gas supply and allow the stove to cool. Wear
safety goggles and a dust mask.

1. Remove the Front, Glass Frame and Glass Panel.
(Figs. 59 & 60) Remove the old gasket. Use a razor
blade to separate the glass and gasket from the frame,
and to clean the glass of any remaining cement or bits
of gasket. Use a cold chisel if necessary.

2. Determine the correct length of gasket by laying it out
around the edge of the glass. Allow an extra 1 - 2” (25­50 mm). Mark the spot to be cut. Use a utility knife.

3. Starting on a long edge, remove about 6” of the pro-

tective paper strip and apply the at adhesive face of

the gasket around the outside-facing edge of the pan­el. Continue around the panel, applying a bout 6” at a
time and being careful to not stretch the material. Do
not overlap the gasket ends. (Fig. 60)

4. Apply a thin bead of high temperature silicone rubber
sealant along the inside corner of the glass frame, all

around the perimeter. Place the at gasketed side of

the glass panel back into the steel frame. Pinch the
rounded inside-facing gasket material to bulk it up.

5. Replace the glass frame and front panel as previously
described.

Inspect the Vent System Annually

Have the vent system inspected annually by a qualied

technician. Shut off the main gas supply before inspect­ing the system. Both the inner exhaust pipe and the outer

combustion supply pipe must be checked to conrm that

they are unblocked and in good condition.

Check the Gas Flame Regularly

To ensure that the stove is operating properly, check the

ames periodically to conrms they match Figure 60. The
ames will be blue during the rst 15-20 minutes of opera-

tion, and will gradually turn to yellow after that.

Do not use your stove if the ame pattern differs from that
shown here. Contact your dealer or a qualied technician

for help.

Stove Disassembly

If there is ever a need to remove the rebox assembly
from the stove shell, support the rebox with solid stands

about 6” (150 mm) tall under the left and right outer edges

of the rebox base. Do not set the rebox assembly di­rectly on the oor; this can damage the control valve and/
or the gas lines from the valve to the rebox.

Before removing the rebox from the shell, disconnect

the on/off switch wires from the valve. If the assembly
includes the optional fan, disconnect the fan rheostat. If
the installation includes a wall thermostat, disconnect the
thermostat leads from valve.

Disconnection and reconnection to the gas line should

only be done by a qualied gas service technician.

Upon reinstallation, the vent system must be sealed to

the rebox as shown in the installation section, Page 16.
Also be sure the logs are placed in the rebox correctly,

as shown in Figures 34 & 35, Page 20.
