• Install gas line into hole provided on insert side. • If applicable install remote control wires into insert side (see Section 6, F.). • Secure collar slide plate to appliance by placing locking handle into position with locking tabs (see Figure 7.1) and secure with #8 screw. • Level the appliance from side to side and front to back. If necessary, use the leveling legs included with the manual bag to set each corner of the base. • Position any excess flexible vent pipe back up into chimney without sagging. Twist and push flex vent together to shorten. • Install fiberglass insulation pieces to back face of surround. • Attach surround. Follow instructions accompanying surround. • Push insert so that surround becomes tight against face of fireplace. WARNING Fire Risk. Only an approved Hearth & Home Technologies surround may be used to cover integral grills on solid fuel burning fireplaces. • No other components such as shrouds, sheet- metal plates, etc., may be used to seal off vents. WARNING Failure to position the parts in accordance with these diagrams or failure to use only parts specifically approved with this appliance may result in property damage or personal injury. WARNING Explosion Risk. Combustion Fume Risk. • Connect vent sections per installation instructions. • The 3 foot section of stainless steel flexible pipe MUST be attached directly to the exhaust collar on the collar slide plate. • Connect exhaust vent pipe ONLY to exhaust starting collar and termination cap center collar. • Connect inlet air vent ONLY to inlet air collar on appliance and either the termination cap inlet air collar OR terminate within chimney. • Do NOT allow vent to sag below connection point to appliance.

Fuel Conversions Before making gas connections ensure that appliance being installed is compatible with the available gas type. Any natural or propane gas conversions necessary to meet the appliance and locality needs must be made by a qualified technician using Hearth & Home Technologies specified and approved parts. B. Gas Pressures Proper input pressures are required for optimum appliance performance. Gas line sizing requirements need to • be made following NFPA54. WARNING Fire Risk. Explosion Hazard. High pressure will damage valve. • Disconnect gas supply piping BEFORE pressure testing gas line at test pressures above 1/2 psig. • Close the manual shutoff valve BEFORE pressure testing gas line at test pressures equal to or less than 1/2 psig. WARNING Verify inlet pressures. • High pressure may cause overfire condition. • Low pressure may cause explosion. • Verify minimum pressures when other household gas appliances are operating. Install regulator upstream of valve if line pressure is greater than 1/2 psig. Pressure requirements for appliance are shown in the table below. Minimum pressu...
