C. Gas Pressure

Proper input pressures are required for optimum appliance performance. Gas line sizing requirements need to be made following NFPA54 and CSA B-149..

WARNING

Fire Risk

Explosion Risk

High pressure will damage valve.

•Disconnect gas supply piping BEFORE pressure testing gas line at test pressures above 1/2 psig.

•Close the manual shutoff valve BEFORE pressure testing gas line at test pressures equal to or less than 1/2 psig.

WARNING

CHECK FOR GAS LEAKS

Fire Risk

Explosion Risk

Asphyxiation Risk

•Check all fittings and connections.

•Do not use open flame.

•After the gas line installation is complete, all connections must be tightened and checked for leaks with a commercially available, non-corrosive leak check solution. Be sure to rinse off all leak check solution following testing.

Fittings and connections may have loosened during shipping and handling.

High Altitude Derate

In the USA, input BTU shall be derated 4% (one orifice size) per 1000 feet for altitudes above 2000 feet. In Canada, input BTU shall be derated 10% (two orifice sizes) at altitudes from 2000-4500 feet.

•Gas Supply Pressure: Minimum inlet gas supply pressure must be 3.5 in. W.C. for the purpose of input adjustment.

Maximum inlet gas pressure must not exceed 10.0 in. W.C. The gas line supplying the appliance must be sufficient size to furnish the appropriate supply pressure to the appliance while operating in the “High” setting.

•Gas Line Pressure Test: Perform pressure test according to state and local code (if pressure exceeds 1/2 in. psi [3.5 kPa]) before appliance is connected. Be sure to release air pressure from the gas line before connection is made to the appliance.

•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. Always check for gas leaks with a mild soap and water solution applied with a brush no larger than 1” (25mm). Never apply soap and water solution with a spray bottle. 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.

•The appliance must only be installed in a solid-fuel burning fireplace with the flue damper clamped open. The fireplace must be constructed of non-combustible material.

•The minimum permanent free opening (in square inches) that must be provided by the fireplace chimney or damper to vent the flue gases is provided in Table 1. If the free opening is smaller than the specified area, do not use 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.
