This gas appliance should be installed by a qualified installer in accor-
dance with local building codes and with current CAN/CGA - B149.1 or .2
installation codes for Gas Burning appliances and equipment in Canada
and the National Fuel Gas Code ANSI Z223 in the U.S.A.
1. The gas pipeline can be brought in through either the right or the left
side of the appliance. A knockout is provided at either location to allow
for the gas pipe installation and testing of any gas connection.
2. The gas control inlet is 3/8" NPT. Typical installation layout for rigid
pipe is shown at right.
3. When using copper or flex connector, use only approved fittings.
Always provide a union so that gas line can be easily disconnected for
burner or fan servicing. See gas specification for pressure details and
ratings.
4. When a vertical section of gas pipe is required for the installation, a
condensation trap is needed. See CAN/CGA-B149.1 or .2 for code
details.
5. For natural gas, a minimum of 3/8" iron pipe with gas minimum pres-
sure of 4.5 w.c. must be used for supply from the gas meter. Consult
with the local gas utility if any questions arise concerning pipe sizes.
6. A 1/8" NPT plugged tappings are accessible for test
gauge connection both on the inlet and outlet of the
gas valve.
7. Turn the gas supply ON and check for leaks. DO
NOT USE OPEN FLAME FOR THIS PURPOSE.
Use an approved leak testing solution.
8. The appliance and its individual shutoff valve must
be disconnected from the gas supply piping system
during any pressure testing of that system at test
pressures in excess of 1/2 PSIG (3.5 KPa).
9. The appliance must be isolated from the gas supply
piping system by closing its individual shutoff valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2
PSIG (3.5 KPa).
Note: The gas line connection may be made of 1/2"
rigid pipe or an approved flex connector. Since
some municipalities have additional local codes, it
is always best to consult your local authorities and
the current CAN/CGA - B149.1 or .2 installation
code in Canada or the National Fuel Gas code ANSI
Z223.1 in the U.S.A.
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 dust, lint etc. to cling to the glass surface. Also,
initial paint curing can deposit a slight film on the glass. It is
therefore recommended that initially the glass be cleaned two or
three times with non-abrasive common household glass
cleansers and warm water. After that, the glass should be
cleaned two or three times a season depending on the circum-
stances.
Warning and Cautions.
• Do not clean when the glass is hot.
• Do not use abrasive cleaners.
• Using a substitute glass will void all product
warranties.
• Do not strike or abuse glass. Care must be
taken to avoid breakage of the glass.
• Do not operate this fireplace without the glass
front or with a broken glass.
Gas Line Installation
Important: Always check for gas leaks with a soap and water solution. Do not
use open flame for leak testing.
