kPa).
Use new black iron or steel pipe. Internally tinned copper or copper tubing can be used per National Fuel Gas
Code, section 2.6.3, providing gas meets sulfide limits, and where permitted by local codes.
An ANSI approved manual shutoff valve must be installed immediately upstream of the gas supply connection
to the fireplace
A sediment trap may be installed upstream of the fireplace to prevent moisture and contaminants from passing
through to the fireplace control and burner. Failure to do so could prevent appliance from operating reliably.
On some local codes, the gas line must be connected to a gas shut-off valve recessed flush into the wall or floor
outside the fireplace. The valve should be controlled by a removable valve key for safety. In this case, remove
factory shut-off valve from the flex line and connect line direct to stub.
WARNING
Support the shut-off valve when attaching 1/2” gas line. Use a wrench to hold shut-off valve stationary.
Do not twist the flex line when tightening the 1/2” gas line.
WARNING
Connecting directly to an unregulated propane/L.P.G. tank can cause an explosion. An external regulator
must be used on all propane/LPG appliances to reduce the supply tank pressure to 13” w.c. (maximum).
WARNING
Do not connect directly to natural gas 1/2- psi or 2-psi systems. Always make sure the natural gas pressure is
regulated to 10.5 w.c. (maximum) before operating the unit.

OPERATING INSTRUCTIONS
Before Lighting the Fireplace:
• Read the IMPORTANT SAFETY INFORMATION section at the beginning of this homeowner manual.
• Before lighting, check the fireplace for possible gas leaks.
• Before lighting, check for possible obstructions that could be blocking the vent termination or the front louver.
• Any component that is found to be faulty must be replaced with an approved component. Tampering with the
fireplace components is dangerous and voids all warranties.
• A small amount of air may be present in the gas line. It will take a few minutes for the lines to purge. Once the
purging is complete, the fireplace will light and will operate normally.
• During the initial purging, never allow the gas valve control knob to remain depressed in the pilot position
without pushing the ignitor button once every second.
• Subsequent lighting of the fireplace will not require this purging of air from the gas lines, unless the gas valve
has been shut-off for a long period.
Lighting the Fireplace:
You may notice the following:
•
•
•
•
A slight odor.
™ During manufacturing, fabricating, and shipping, various components of this fireplace are treated with
certain oils, film, or bonding agents. These chemicals are not harmful but may produce annoying smoke
and smells as they are burned off during the initial operation of the fireplace. Operate the appliance 2 to 3
hours at the highest setting to burn off all the oils, films, etc.
Fogging on Bi-Fold Door glass.
™ For the first few minutes, after each lighting, vapor may condense and fog the glass. This condensation will
disappear in a few minutes.
Noise from the fireplace.
™ This is due to metal expanding and contracting as it heats up and cools down, similar to the sound produced
by a furnace or heating duct.
Flame appearance.
™ It will take about 15 to 30 minutes for the flames to turn yellow and some portions of the logs to glow.
