The thermopile generates the millivolt supply that powers the valve, so the appliance itself does not depend on household current to operate. HearthStone specifies a thermopile output of 325 to 500 millivolts. The valve extinguishes the pilot after 7 days without a call for heat, a feature HearthStone describes as meeting the requirements of states and municipalities that do not permit continuously burning pilots. The owner's manual warns that the timer system must not be defeated or modified.\u003c\/p\u003e\n\u003ch4\u003eBattery-Powered Continuous Sparker for Pilot Ignition\u003c\/h4\u003e\n\u003cp\u003eThe pilot is lit by a continuous spark igniter connected to the pilot assembly, powered by a single AA battery housed in a sparker box mounted below the stove. The spark begins as the gas control knob is pressed in at the pilot position. HearthStone directs that the appliance must not be lit by a match or by any means other than the supplied ignition system, and recommends replacing the battery each season.\u003c\/p\u003e\n\u003ch4\u003eManual, Thermostat or Optional Remote Operation\u003c\/h4\u003e\n\u003cp\u003eThe Waitsfield can be run manually at the gas control valve, with a wall-mounted 750 millivolt thermostat, or with an optional remote control kit. The thermostat is not supplied with the appliance. A variable output control on the gas valve adjusts heat output between the published minimum and maximum inputs, so a low flame setting gives longer burn cycles at reduced output and a high setting gives a shorter, hotter cycle.\u003c\/p\u003e\n\u003ch4\u003eSteel Pan Burner, Five-Piece Log Set and Ember Media\u003c\/h4\u003e\n\u003cp\u003eModel 8771 is published with a steel pan burner. The stove ships with a five-piece decorative ceramic log set packed separately, a bag of Platinum Bright Embers and a bag of ceramic nuggets. The manual specifies an exact log and ember placement sequence, which is required for a correct flame pattern and clean combustion.\u003c\/p\u003e\n\u003ch4\u003eIntegral Cast-Iron Heat Exchanger\u003c\/h4\u003e\n\u003cp\u003eA cast-iron heat exchanger is integral to the appliance. HearthStone describes its purpose as moving heat from the fire into the room rather than up the chimney.\u003c\/p\u003e\n\u003ch4\u003eIntegral Safety Barrier Screen\u003c\/h4\u003e\n\u003cp\u003eThe Waitsfield includes a safety barrier screen as an integral part of the appliance. The screens are mechanically affixed to the inside surface of the front and side castings, and HearthStone requires that a damaged barrier be replaced with the manufacturer's barrier for this appliance before the stove is operated.\u003c\/p\u003e\n\u003ch4\u003eNatural Gas as Shipped, Propane with the Included Kit\u003c\/h4\u003e\n\u003cp\u003eThe Waitsfield is factory equipped to burn natural gas. A propane conversion kit is included with the appliance and must be installed by qualified service personnel before the stove is operated on propane. Maximum input is 32,500 BTU\/hr on natural gas and 33,000 BTU\/hr on propane, with minimum inputs of 17,500 BTU\/hr and 18,500 BTU\/hr respectively. The Model 8771 rating label publishes the same maximum ratings at 0 to 2,000 ft and at 2,000 to 4,500 ft, and the manual states that the de-rating gas suppliers typically apply above 2,000 ft is not necessary with the Waitsfield.\u003c\/p\u003e\n\u003ch4\u003eOptional Blower and Optional Remote\u003c\/h4\u003e\n\u003cp\u003eA convection blower and two remote control options are optional on Model 8771 and are sold separately. None of them is included with the appliance. The blower mounts below the stove, is switched on automatically by a snap switch once the stove body reaches temperature, and is speed-adjusted with a rheostat. The blower requires household current; the appliance itself operates on its own millivolt system.\u003c\/p\u003e\n\u003ch4\u003eDirect Vent Installation\u003c\/h4\u003e\n\u003cp\u003eThe Waitsfield is a direct vent appliance using a 4\" x 6-5\/8\" vent with a top outlet at the stove. HearthStone approves two venting configurations for this model: vertical venting with vertical termination, and vertical venting with horizontal termination. Vent components must come from an approved manufacturer and must not be mixed between manufacturers within the same venting system.\u003c\/p\u003e\n\u003ch4\u003eApproved for Mobile Home Installation\u003c\/h4\u003e\n\u003cp\u003eModel 8771 is approved for installation in an aftermarket, permanently located manufactured home in the United States where not prohibited by local codes, and the rating label is marked certified for mobile home installation. The rating label is also marked certified for Canada.\u003c\/p\u003e\n\u003ch4\u003eMade in the USA\u003c\/h4\u003e\n\u003cp\u003eThe Model 8771 rating label identifies HearthStone QHHP, Inc. of Morrisville, Vermont as the manufacturer and is marked Made in USA.\u003c\/p\u003e\n\u003ch3\u003eAvailable Finishes and Configurations\u003c\/h3\u003e\n\u003cp\u003eAll three configurations are the same Model 8771 appliance and differ only in exterior finish.
