Input ratings are shown in BTU per hour and are
certified without deration for elevations up to
4,500 feet (1,370m) above sea level.
For elevations above 4,500 feet (1,370m) in USA,
installations must be in accordance with the
current ANSI Z223.1 and/or local codes having
jurisdiction.
In Canada, please consult provincial and/or local
authorities having jurisdiction for installations at
elevations above 4,500 feet (1,370m).
Preparation
Before beginning, remove glass door and logs from
unit. Also check to make sure there is no hidden
damage to the unit. Take a minute and plan out the
gas,venting and electrical route. It is best to start with
the gas line first followed by the chimney liner. (Refer to
Page 8)
Gas Line Installation
When purging the gas line, the front
glass must be removed.
The gas pipeline can be brought into the fireplace base
from the right side. It is most convenient to install it
from the right side into the valve.
When using copper or flex connector use
only approved fittings. Always provide a
union when using black iron pipe so the gas
line can be easily disconnected for burner or
fan servicing. See gas specification for
pressure details and ratings.
The gas line connection can be made of
either properly tinned 3/8" copper pipe, 3/8" rigid pipe
or an approved flex connector. Since some
municipalities have some additional local codes, it is
always best to consult your local authority and the
CSA- B149.1 installation code.
U.S. Installations consult the current National Fuel
Gas Code, ANSI Z223.1
The gas control inlet is 3/8" N.P.T. therefore the 1/2"
rigid gas line must be reduced to 3/8" N.P.T. Typical
installation layout for rigid pipe is shown following. (Fig.
1)
During any pressure testing of the gas line system,
when the test pressures are to exceed 1/2 psi (3.5 kpa)
the fireplace and its gas valve must not be connected
to that system.
At test pressures equal to or less than 1/2 psi, the gas
valve of the fireplace may be connected to the gas line,
but must be in the closed position.

with screws supplied with the gas fire-
place insert to the inside of the firebox of
the fireplace into which the gas fireplace
insert is installed.
Cutting any sheet metal parts of the
fireplace, in which the gas fireplace insert
is to be installed, is prohibited.
If the factory-built fireplace has no gas
access hole(s) provided, an access hole
of 1.5 inch (37.5mm) or less may be
drilled through the lower sides or bottom
of the firebox in a proper workmanship
like manner. This access hole must be p
lugged with a noncombustible insulation
after the gas supply line has been in-
stalled.
WARNING
Some factory-built fireplaces have air passages
on face of fireplace for zero clearance capabilities.
All trim kits are designed so as to allow airflow to
these passages. Under no circumstances should
these passages be blocked.
The collar extending down from the termina-
tion base is the air intake connector. Be sure
the flex vent, which is connected to this
collar, is also connected to the labelled air
intake flue collar on the fireplace. Make sure
the Flex vent is attached on the correct collar
and cap for exhaust as well.
Slide the insulation provided in the termination kit over
the two (2) 3" flex liners, (to be attached to the 3" Flue
collar and cap of the termination). Feed one 3" flex vent
from the bottom of the termination up through the 4"
sleeve. Apply hi-temp sealant on the rain cap collar
and slide the flex vent over the end of the rain cap
collar fastening with the clamp provided. Slide the flex
liner back down the 4" sleeve until 4" cap slides over
the sleeve. Attach cap to the sleeve with four (4) screws
supplied. Apply hi-temp sealant over the air intake
collar and attach intake flex vent in the same method.
Feed the two flex liners down the chimney through the
damper opening. Tighten termination to the chimney
using the screws provided.
In case the fireplace opening is only minimum height
21" (533mm) and access from the front is not possible,
then follow the instructions below.
1. Remove flue collar plate assembly. Unbolt the top
fastener plate and move it to the back first before
sliding the flue collar plate out from the top of the
unit. (Fig. 10)
2. Apply a bead of hi-temp sealant on the end of the
collar before attaching the liner to the flue collar.

Glass Cleaning
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 cling to the glass surface. Also
initial paint curing may deposit a slight film 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 fireplace 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 first two weeks of
operation.
Glass Frame Removal
1. Remove four (4) bottom fastening screws with a
3/8" nut driver. (Fig. 17)
2. Lift up and unhook glass frame at the top.
Log Installation and Burner Lava Rock
1 . Remove front glass. (See "Glass Removal" section)
2. Remove logs from packaging.
3. Place rear log (JR4, KR4 or SR4) on rear bracket
(ensure log is seated properly, leveled and centered
to the unit), so it will not move from side to side and
is firmly positioned on the bracket.
4. Slip front ember log (JR1, KR1 or SR1) down in the
front deflector.
5. Place front left log (JR2 ,KR2 or SR2) on top

First Firing
Upon completing the gas line connection, a small
amount of air will be in the lines. When first lighting unit
with pilot light, it will take a few minutes to purge them-
selves of this air. Once the purging is complete, the
pilot and burner will light and operate as indicated in the
instruction manual. Subsequent lightings of the heater
will not require such purging.
When lit for the first time, the appliance will emit a slight
odor for awhile. This is due to paint and lubricants used
in the manufacturing process. After each lighting, vapor
may condense and fog the glass; this moisture disap-
pears within a few minutes of burning.

Maintenance
Burner and Burner Compartment
It is important to keep the burner and the burner
compartment clean. At least once per year the logs and
lava rock/ember material should be removed and the
burner compartment vacuumed and wiped out. Remove
and replace the logs as per the instructions in this
manual. Always handle the logs with care as they
are fragile and may also be hot if the
fireplace has been in use.
Fan Assembly
The fan unit requires periodic cleaning. At least once
per month in the operating season, open the lower
louvre panels and wipe or vacuum the area around the
fan to remove any build up of dust or lint.
Cleaning the Standing Pilot
Control System
The burner and control system consists of:
• main burner • pilot burner
• gas orifice • thermopile
• combination millivolt gas valve
Most of these components may require only an occa-
sional checkup and cleaning and some may require
adjustment. If repair is necessary, it should be per-
formed by a qualified technician.
In order to properly clean the burner and pilot assembly,
turn off the gas to the unit, remove the window frame
panel and logs exposing the burner and pilot assembly.
Clean all foreign materials from the top of the burner.
Check to make sure that burner parts are clean.
Visually inspect pilot. Brush or blow away any dust or
lint accumulation. If pilot orifice is plugged, disassembly
may be required to remove any foreign material from
the orifice or tubing.
To obtain proper operation, it is imperative that the pilot
and burner's flame characteristics are steady, not lifting
or floating.
Typically, the top 1/8" of the thermopile should be
engulfed in the pilot flame. (Page 13, Fig. 24)
Brass Cleaning
Clean the brass trim with a soft clean cloth, slightly
dampened with lemon oil and buff with a soft dry cloth.
Do not use brass polish or household cleaners as these
products will damage the trim. Lemon oil can be
obtained at supermarkets or hardware stores.
