Follow all local codes.Installation Items NeededBefore installing heater, make sure you have the items listed below.• external regulator - propane/LP only (supplied by installer)• piping (check local codes)• sealant (resistant to propane/LP gas)• equipment shutoff valve *• test gauge connection *• sediment trap• tee joint• pipe wrench* A CSA design-certified equipment shutoff valve with 1/8" NPTtap is an acceptable alternative to test gauge connection. Purchasethe optional CSA design-certified equipment shutoff valve fromyour dealer. See Accessories, page 26.The gas inlet connection for the stove heater is located on the lowerright-hand side of the stove when viewed from the front of the unit.The gas connection can be made either through the bottom right sideor through the lower back opening as illustrated in Figure 17. Makesure gas log heater is secured to the stove cavity assembly.For propane/LP units, installer must supply an external regulator.The external regulator will reduce incoming gas pressure. You mustreduce incoming gas pressure to between 11 and 14 inches of water.If you do not reduce incoming gas pressure, heater regulator damagecould occur. Install external regulator with the vent pointing downas shown in Figure 18. Pointing the vent down protects it fromfreezing rain or sleet.CAUTION: Never connect propane/LP heater di-rectly to the propane/LP supply. This heater requiresan external regulator (not supplied). Install the externalregulator between the heater and propane/LP supply.WARNING: This appliance requires a 1/2" NPT(National Pipe Thread) inlet connection to the pres-sure regulator.WARNING: Never connect natural gas heater toprivate (non-utility) gas wells. This gas is commonlyknown as wellhead gas.Figure 17 - Gas Regulator Location and Gas Line Access IntoStove CabinetGas InletConnectionAccessProductIdentificationLabelGas Log HeaterBack ViewSide ViewFigure 18 - External Regulator With Vent Pointing DownBackStovePanelStoveUnitFrontPropane/LPSupply TankExternalRegulatorVent PointingDownCAUTION: Use only new, black iron or steel pipe.Internally-tinned copper tubing may be used in certainareas. Check your local codes. Use pipe of 1/2" diam-eter or greater to allow proper gas volume to heater. Ifpipe is too small, undue loss of volume will occur.Installation must include a equipment shutoff valve, union, andplugged 1/8" NPT tap. Locate NPT tap within reach for test gaugehook up.
