MAINTENANCE

Important: When lit for the first time, the appliance will emit

a slight odour for a couple of hours. This is due to the curing
of paints, sealants and lubricants used in the manufacturing
process. This condition is temporary. Open doors and
windows to ventilate area. If optional fan kit has been
installed, place fan in the "OFF" position. Smoke and fumes
caused by the curing process may cause discomfort to some
individuals.

It is normal for fireplaces fabricated of steel to give off some
expansion and/or contraction noises during the start up or cool
down cycle. Similar noises are found with your furnace heat
exchanger or cook stove oven.

CAUTION

FOR YOUR SAFETY - Do not install or operate your Pacific Energy

fireplace without first reading and understanding this manual. Any
installation or operational deviation from the following instructions
voids the Pacific Energy Warranty and may prove hazardous.

overlay in reverse order.

Annual Inspection:

a) Clean air passage ways of excessive lint and dust build-up from
carpeting, bedding material, etc. The flow of ventilation air must not be
obstructed.
b) Remove glass panel and log set. Inspect logs and burner
assembly for lint and soot build-up. If excessive build-up of soot is
present, have a qualified service person inspect and adjust unit for
proper combustion. Clean logs and burner with a vacuum cleaner,
paying close attention to the ports on the burner.
c) Check the pilot system for proper flame size and operation. Clean
pilot free of lint and dust. (See Fig. #1)
d) Check that the vent pipe and vent terminal are open and free from
blockage or debris. If the venting system is disassembled for cleaning,
it must be properly assembled and resealed. Refer to VENTING
section for proper procedure.
e) Check glass panel gasket, replace if necessary. It is important that
the glass seal be maintained in good condition.
Note: The appliance area must be kept clear and free from combus­tible materials, gasoline and other flammable vapours and liquids.

• Clothing or other flammable material should not be placed on
or near the appliance.

• Under no circumstances should this fireplace be modified.

or national building codes before proceeding.

The Oxford comes equipped with a flexible connector with a 3/8"
N.P.T. male inlet for easy gas connection.
Correct gas line diameter must be used to assure proper operation.

Correct gas pressure requirements:

Natural Gas Propane

Min. Pressure 5.0" wc 11.5" wc

(For purpose of input adjustment)

Max Pressure 10.5" wc 13.0" wc

Manifold Pressure

Maximum 3.8" wc 11.0" wc
Minimum 1.1" wc 2.9" wc

The gas control is equipped with a captured screw type pressure test
point, therefore it is not necessary to provide a 1/8 inch N.P.T. plugged
tapping pressure test port for checking gas pressure immediately
upstream of the gas supply connection to the appliance.

The minimum clearances from the appliance to combustibles are
shown on Fig. # 3. For purpose of servicing, a 10" right side clearance
(side with controls) is recommended. Adequate clearances around air
openings and combustion air supply are required.
* Alcove sidewall to appliance clearance is listed at 4 3/4". A 10"
clearance is recommended to center the appliance in a 48" minimum
wide Alcove.

STRAIGHT THROUGH WALL INSTALLATION

f i r e - p a r t s . c o m

1) Determine the exact position of the gas stove so that the direct
vent pipe is centred (if possible) between two building framing
members. This will avoid any extra framing.

2) Carefully measure up 22-inches from the finished floor and mark
the centre of a 9-inch square or round hole. (See Figure # 6)

IMPORTANT: When locating this hole it should be noted that the
bottom of the vent terminal must be a MINIMUM of 12-inches
above grade, the top of the terminal must be a MINIMUM of 18­inches below combustible material such as a deck or roof over­hang and the side of the terminal must be a MINIMUM of 12-inches
away from an adjacent wall. (See Figure 10)

3) Cut a 9-inch square or round hole through the exterior wall of the
building.

4) Position the wall thimble spacer (WTS) from the inside through the
9-inch hole. (Figure 6). For walls less than 11-inches thick, the
thimble must be trimmed back flush with the exterior wall.

5) Attach the trim collar to the flanges of the wall thimble with the
screws provided.

6) The coaxial starter pipe (SK 18) may have to be cut to length
depending on the wall thickness and/or rear clearance of the
stove. Measure the wall thickness from the finished trim collar
surface to the exterior mounting surface for the vent terminal. Add
1/4 inch plus rear clearance to the wall thickness (i.e. rear
clearance of 1", add 1 1/4" , rear clearance of 3", add 3 1/4" to wall
thickness).

pipe over top of the collar up to the crimp-bead and attach with
three sheet metal screws. Seal the joint with high temperature
silicone. Next, slide the 7-inch outer pipe over the 5-inch pipe fully
and secure to the pipe collar with three sheet metal screws. Assure
that the vent pipe is level or has a 1/4" rise for every foot of run
towards the termination.

9) Slide the appliance into place, with vent pipe centred in wall pass­through. When the unit is properly installed, the 7-inch vent pipe
will project 3/4-inch past the outside wall surface and the 5-inch
inner pipe will extend 1-inch past that. Assure that the vent pipe is
level or has a 1/4" rise for every foot of run towards the termination.

10) Install vent terminal according to section VENT TERMINAL

CORNER INSTALLATION

1) Determine the exact position of the gas stove, making sure the unit
will be set at 45° to the walls and the corner clearance will not be
less then 1-inch. The vent pipe should be centred (if possible)
between two building members. This will avoid any extra framing.

2) Once the desired location is found, carefully measure up 22­inches from the finished floor and make a mark. Next, measure 7­inches plus the actual corner clearance of the appliance over from
the corner of the room and make a mark. (i.e. corner clearance of
1", measure 8"; corner clearance of 3", measure 10")

IMPORTANT: When locating this hole it should be noted that the
bottom of the vent terminal must be a MINIMUM of 12-inches
above grade, the top of the terminal must be a MINIMUM of 18­inches below combustible material such as a deck or roof over­hang and the side of the terminal must be a MINIMUM of 12-inches
away from an adjacent wall (See Figure 10).

3) Cut a 9-inch square or round hole through the exterior wall of the
building.

4) Position the wall thimble spacer (WTS) from the inside through the
9-inch hole. (Figure 6). For walls less than 11-inches thick, the
thimble must be trimmed back flush with the exterior wall.

5) Attach the trim collar to the flanges of the wall thimble with the
screws provided.

6) Attach the coaxial 45° elbow (LB 45) to the unit. Slide the 5-inch
inner elbow pipe 1-inch over top of the collar and secure with three
sheet metal screws. Seal the joint with high temperature silicone.

f i r e - p a r t s . c o m

Next, slide the outer elbow pipe over the smaller elbow and secure
to the pipe collar with three sheet metal screws.

7) The coaxial starter pipe (SK 18) may have to be cut to length
depending on the wall thickness and/or corner clearance of the
stove. Measure the wall thickness from the finished trim collar
surface to the exterior mounting surface for the vent terminal. Add
3 3/4-inches plus corner clearance to the wall thickness. (i.e.
corner clearance of 1", add 4 3/4" , corner clearance of 3", add 6
3/4" to wall thickness)

Fig. # 7

8) Cut both pipes to this length.

9) Slide the inner 5-inch flue pipe over top of the crimped end of elbow
and attach with three sheet metal screws. Seal the joint with high
temperature silicone. Next, slide the 7-inch outer elbow pipe over
the 5-inch elbow fully and secure to the elbow with three sheet
metal screws. Assure that the vent pipe is level or has a 1/4" rise
for every foot of run towards the termination.

10) Slide the appliance into place making sure vent pipe is centred in
wall pass-through. When the unit is properly installed, the 7-inch
vent pipe will project 3/4-inch past the outside wall surface and the
5-inch inner pipe will extend 1-inch past that.
