This is perfectly normaldue to the fact that there are various gaugesand types of steel used within your appliance.Listed below are some examples. All are normaloperating sounds and should not be consideredas defects in your appliance.Blower:Regency® gas appliances use high tech blowersto push heated air farther into the room. It is notunusual for the fan to make a "whirring" soundwhen ON.Burner Tray:The burner tray is positioned directly under theburner tube(s) and logs and is made of a differentgauge material from the rest of the firebox andbody. Therefore, the varying thicknesses of steelwill expand and contract at slightly differentrates which can cause "ticking" and "cracking"sounds. You should also be aware that as thereare temperature changes within the unit thesesounds will likely re-occur. Again, this is normalfor steel fireboxes.Blower Thermodisc:When this thermally activated switch turns ONit will create a small "clicking" sound. This is theswitch contacts closing and is normal.Pilot Flame:While the pilot flame is on it can make a veryslight "whisper" sound.Gas Control Valve:As the gas control valve turns ON and OFF, adull clicking sound may be audible, this is normaloperation of a gas regulator or valve.Unit Body/Firebox:Different types and thicknesses of steel willexpand and contract at different rates resultingin some "cracking" and "ticking" sounds will beheard throughout the cycling process.During the first few fires, a white filmmay develop on the glass front as part ofthe curing process. The glass should becleaned after the unit has cooled downor the film will bake on and become verydifficult to remove. Use a non-abrasivecleaner and DO NOT ATTEMPT TO CLEANTHE GLASS WHILE IT IS HOT.The FIRST FIRE in your heater is part of thepaint curing process. To ensure the paint is prop-erly cured, it is recommended you burn yourfireplace for at least four (4) hours the first time.When first operated, the unit will release anodour caused by the curing of the paint and theburning off of any oils remaining from manufac-turing. Smoke detectors in the house may go offat this time. Open a few windows to ventilatethe room for a couple of hours. The glass mayrequire cleaning.NOTE: When the glass is cold and the applianceis lit, it may cause condensation and fogthe glass. This condensation is normaland will disappear in a few minutes asthe glass heats up.DO NOT ATTEMPT TO CLEAN THEGLASS WHILE IT IS STILL HOT!DO NOT BURN THE UNIT WITHOUT THEGLASS DOOR IN PLACE.FIRST FIRE
