Also caulk the perimeter of flashing that contacts roof surface as shown in Figure 8.16. To attach the vertical termination cap, slide the inner collar of the cap into the inner flue of the pipe section and place the outer collar of the cap over the outer flue of the pipe section. Secure with three screws into the outer flue. Secure the cap by driving the three self-tapping screws (supplied) through the pilot holes in the outer collar of the cap into the outer flue of the pipe (see Figure 8.15). SCREWS CAULK STORM COLLAR (1 of 3) Figure 8.15 TERMINATION CAP WARNING Fire Risk. Explosion Risk. Inspect external vent cap regularly. • Ensure no debris blocks cap. • Combustible materials blocking cap may ignite. • Restricted air flow affects burner operation.

H • 11/08 Assembling and Installing Storm Collar CAUTION Sharp Edges • Wear protective gloves and safety glasses during installation. Connect both halves of the storm collar with two screws (see Figure 8.17). Wrap the storm collar around the exposed pipe section and align brackets. Insert a bolt (provided) through the brackets and tighten nut to complete storm collar assembly (see Figure 8.18). Slide the assembled storm collar down the pipe section until it rests on the roof flashing. Caulk around the top of the storm collar (see Figure 8.15).

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 C. Gas Connection Note: Have the gas supply line installed in accordance with local building codes, if any. If not, follow ANSI 223.1. Installation should be done by a qualified installer approved and/or licensed as required by the locality. (In the Commonwealth of Massachusetts installation must be performed by a licensed plumber or gas fitter). Note: A listed (and Commonwealth of Massachusetts approved) 1/2 inch (13 mm) T-handle manual shut-off valve and flexible gas connector are connected to the 1/2 inch (13 mm) control valve inlet. • If substituting for these components, please consult local codes for compliance. 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 pressures must be met when other household gas appliances are operating. Refer to Reference Section 16 for location of gas line access in appliance. Gas Leak Risk • Support control when attaching pipe to prevent bending gas line. WARNING Note: Gas line may be run from either side of the appliance provided the hole in the outer wrap does NOT exceed 2-1/2 inches in diameter and does not penetrate the firebox. Note: The gap between supply piping and gas access hole may be caulked with high temperature caulk or stuffed with non-combustible, unfaced insulation to prevent cold air infiltration. Pressure Natural Gas Propane Minimum inlet pressure 5.0 inches w.c. 11.0 inches w.c. Maximum inlet gas pressure 14.0 inches w.c. 14.0 inches w.c. Manifold pressure 3.5 inches w.c. 10.0 inches w.c. Heat & Glo • Cerona-36, Cerona-42 • 2106-900 Rev. H • 11/08 • Ensure that gas line does not come in contact with outer wrap of appliance. Follow local codes. • Incoming gas line should be piped into the valve compartment and connected to the 1/2 inch connection on the manual shutoff valve. WARNING Fire or Explosion Hazard • Gas buildup during line purge may ignite. • Purge should be performed by qualifi ed technician. • Ensure adequate ventilation. • Ensure there are no ignition sources such as sparks or open flames. HIGH ALTITUDE INSTALLATIONS U.L. Listed gas appliances are tested and approved without requiring changes for elevations from 0 to 2000 feet in the U.S.A. and Canada. When installing this appliance at an elevation above 2000 feet, it may be necessary to decrease the input rating by changing the existing burner orifice to a smaller size. Input rate should be reduced by 4% for each 1000 feet abov...
