6WS-415-131 / A / 09.11.004. For ease of accessibility, an optional remote wallswitch or millivolt thermostat may be installed in a con-venient location. Route a 2 strand, solid core millivolt wirethrough the electrical hole located at the bottom left side ofthe unit. The recommended maximum lead length de-pends on wire size:WIRE SIZE MAX. LENGTH14gauge 100 feet16gauge 60 feet18gauge 40 feetAttach the two leads to terminals 1 and 3 located on thegas valve.Do not connect either the wall switch, thermostat orgas valve to electricity (110 volts).USING DOOR OPTION:Purge all gas lines with the glass door of the fireplaceopened. Assure that a continuous gas flow is at theburner before closing the door.Unusually tight construction is defined as con-struction where:a) Walls and ceilings exposed to the outside atmos-phere have a continuous water vapour retarder with arating of 1 perm (6 x 10 -11 kg per pa-sec-m2 ) or less withopenings gasketed or sealed, andb) Weather stripping has been added on openablewindows and doors, andc) Caulking or sealants are applied to areas such asjoints around window and door frames, between soleplates and floors, between wall-ceiling joints, betweenwall panels, at penetrations for plumbing, electrical, andgas lines, and at other openings.An unvented room heater is recommended for use as asecondary heat source rather than as a primary source.Gas combustion produces water vapour which could oc-cur at the rate of approximately one ounce of water forevery 1,000 BTU/hr of gas input. During the cold weatherseason, indoor humidity levels tend to be low. Conse-quently, this water vapour can enhance the living space.However if a problem should occur:a) ensure sufficient combustion and circulation airb) use a dehumidifierc) do not use the unvented room heater as a primaryheat sourceWithout sufficient fresh air for proper operation, poor fuelcombustion can result. Carbon Monoxide is a result ofpoor combustion.If additional fresh air is required, use one of themethods described in the National Fuel Gas Code,ANSI Z223.1, Section 5.3 or the applicable local code.GAS INSTALLATION1. Move the fireplace into position and secure using thenailing tabs and/or secure to the floor through the ¼"øholes located at either end of the base.2. Install rigid black pipe, 1/2" type-L copper tubing or, iflocal codes permit, a 3/8" flex connector and shutoff valveto the gas line and the fireplace gas valve. Seal and tightensecurely. An adapter fitting is required between the gasvalve and the copper tubing or flex connector.DO NOT KINK FLEX CONNECTOR.3. Check for gas leaks by brushing on a soap and watersolution.DO NOT USE OPEN FLAME.FIGURE 2PIPILOT312NOLOTHILOFFOFIGURE 3FIGURE 4
