10 Regency U41-3 ULTIMATE Gas Fireplace InsertINSTALLATIONBefore installing vent system ensure that thedamper plate is locked into the open positionand secure to prevent the damper plate fromfalling down and crushing the liner.GAS PRESSURE TESTThe unit is preset to give the correct gas input atthe specified manifold pressures shown on thelabel. The maximum gas manifold pressure is:Natural Gas: 3.8" w.c.Propane 11" w.c.The manifold pressure is controlled by a regu-lator built into the gas control, and should bechecked at the pressure test point. The pres-sure check should be carried out with the unitburning and the setting should be with in thelimits specified.Natural Gas: 3/16" openPropane: 1/2" openThe aeration adjustment gears are located onthe right side of the burner box and can be ac-cessed from the side or from the front when thelouvers are removed.Note: Use the same manner to check theinlet pressure.AERATION SYSTEMThe burner aeration is factory set but may needadjusting due to either the local gas supply, airsupply or altitude.The Regency Insert incorporates its own inter-nal draft hood, so no additional external drafthood is required. Periodically check that thevent is unrestricted and an adequate draft ispresent when theunit is in operation.(See page 9 forspillage test.)To adjust the aeration: use the allen key to turnthe turning gear which will adjust the air shutter.Open the air shutter for a blue flame or close itfor a yellower flame.Clockwise to open,counter-clockwise to close.Caution: Carbon will be produced if the airshutter is closed too much.Note: Any damage due to carboning re-sulting from improperly setting theaeration controls is NOT coveredunder warranty.Note: Aeration Adjustment should only beperformed by an authorized RegencyInstaller at the time of installation orservice.TEST FOR FLUESPILLAGEA “spillage” test must be made before the in-stalled unit is left with the customer. Follow theprocedure below:1) Start all exhaust fans in the home and thenclose all doors and windows in the room.2) Light the unit and set controls to maximum.Turn fan off.3) After fi ve minutes, test that there is a “pull”on the flue by placing a smoke match,cigarette or similar device which gives offsmoke, in front of the spill tube. To ensurea valid test, place a scrap piece of sheetmetal (or other non-combustible material)between the spill tube and the upper louver,this will prevent the natural convection ofthe unit from interfering with the test. Seediagrams below.normal draft downdraft orblocked fl ueSpill TubeNon-combustibleScrapThe smoke should be drawn into the spill tube,if it does not, leave the unit for a further fi veminutes and retest as above. If the smoke isstill not drawn into the spill tube, turn the unitoff and check for the cause of the lack of draft.If necessary, seek expert advice.For wind turbulent sites, a wind cap may remedythe problem.Note: The thermally activated safety switchwill sense the change in temperatureand shut down the gas valve in theevent of a severe downdraft of airor a blocked or disconnected vent.The switch acts as a safety shut-offto prevent a build up of carbon mon-oxide. If the flue is blocked or has no"draw", the switch will automatically
