WARNING
Fire Risk
Explosion Risk
• Gas build-up during line purge may
ignite.
• Purge should be performed by qualified
technician.
• Ensure adequate ventilation.
• Ensuretherearenoignition sources such
as sparks or open flames.
C. Gas Pressure
Proper input pressures are required for optimum appliance
performance. Gas line sizing requirements need to be made
following NFPA51.
Fire Risk
Explosion Risk
High pressure will damage valve.
• Disconnect gas supply piping BEFORE
pressuretestinggaslineat test pressures
above 1/2 psig.
• Closethe manual shutoffvalveBEFORE
pressuretestinggaslineat test pressures
equal to or less than 1/2 psig.
WARNING
High Altitude Derate
Inthe USA, inputBTU shall bederated 4% (one orifice size)
per1000feetfor altitudesabove2000 feet. In Canada,input
BTU shall be derated 10% (two orifice sizes) at altitudes
from 2000-4500 feet.
• GasSupply Pressure:Minimum inletgas supplypressure
must be 4.5 in. W.C. for natural gas or 11 in. W.C. for LP
gas for the purpose of input adjustment. Maximum inlet
gas pressure must not exceed 7.0 in. W.C. for natural
gas or 13 in. W.C. for LP gas. The gas line supplying the
appliancemustbe sufficient sizeto furnishthe appropriate
supply pressure to the appliance while operating in the
“High” setting. (Minimum line ID of 1/2 in. required if the
line is longer than 20 ft.).
• Gas Line Pressure Test: Perform pressure test according
tostate and localcode (ifpressure exceeds1/2 in.psi [3.5
kPa]) before appliance is connected. Be sure to release
air pressure from the gas line before connection is made
tothe appliance.Excessive pressurewill damage thegas
control and may cause a gas leak.
• Gas Leak Test: Make sure the gas connections are tight.
Turn on the gas and coat each joint with a non-corrosive
gas leak check solution. Air bubbles will form indicating
any leaks. DO NOT USE A FLAME OR ANY TYPE OF
IGNITION SOURCE TO CHECK FOR LEAKS. All leaks
must be corrected before proceeding with installation.
• Theappliancemust only be installedin a solid-fuelburning
fireplace with the flue damper clamped open.
• The minimum permanent free opening (in square inches)
thatmust beprovided bythefireplace chimneyor damper
to vent the flue gases is provided in Table 1. If the free
openingis smallerthan the specifiedarea, do notuse this
appliance.
• The damper must be removed or fixed in a manner in
which will secure it open. Some jurisdictions require the
damper to be removed or permanently welded fully open.
Check with state and local codes.
• Be sure that the chimney is completely unobstructed to
ensure proper ventilation of flue gases including carbon
monoxide (CO).CO (a poisonous gas) is tasteless,
odorless, colorless and undetectable without proper
equipment.
WARNING
CHECK FOR GAS LEAKS
Fire Risk
Explosion Risk
Asphyxiation Risk
• Check all fittings and connections.
• Do not use open flame.
• Afterthe gasline installationis complete,
all connections must be tightened and
checked for leaks with a commercially
available, non-corrosive leak check
solution.Besuretorinse off all leakcheck
solution following testing.
Fittingsandconnections may haveloosened
during shipping and handling.
WARNING
Fire Risk
Explosion Risk
Do NOT change the valve settings.
• This valve has been preset at the
factory.
• Changingvalve settings mayresult infire
hazard or bodily injury.
• Prevent accidental appliance operation when not
attended.
• Unplug or remove batteries from remote control if
absentorifappliance will notbeused for an extended
period of time.
• Property damage possible from elevated
temperatures.
