Resumen del manual
It is required by the National Fuel Gas Code that a drip line be installed near the gas inlet. This should consist of a vertical length of pipe tee connected into the gas line that is capped on the bottom in which condensation and foreign particles may collect. The use of the following gas connectors is recommended: – ANSI Z21.24 Appliance Connectors of Corrugated Metal Tubing and Fittings, CGA 6.10 – ANSI Z21.45 Assembled Flexible Appliance Connectors of Other than All–Metal Construction. The above connectors may be used if accepted by the local codes or authority having jurisdiction. Pressure Testing of the Gas Supply System 1. To check the inlet pressure to the gas valve, a plugged tapping, accessible for test gauge connection, is provided on the gas valve (Figure 8). 2. The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of in excess of 1/2 psig (3.5 kPa). 3. The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa). Attention: If any of the above procedures results in pressures in excess of 1/2 psig (14” w.c., 3.5 kPa) on the appliance gas valve, it will result in a hazardous condition. High Altitudes (U.S. Only) For altitudes/elevations above 2,000 feet (610 m), ratings should be reduced at the rate of 4 percent for each 1,000 feet (305 m) above sea level by reducing the manifold pressure at a rate of 8% on the gas supply. Maximum altitude allowed for installation is 5,500 feet (1680 m). High Altitudes (Canada Only) The appliance is tested according to CGA 2.17 M91 for installation between 0 and 4,500 feet (0 and 1370 m) altitude. For altitudes/elevations above 2,000 feet (610 m), ratings should be reduced at the rate of 4 percent for each 1,000 feet (305 m) above sea level by reducing the manifold pressure at a rate of 8% on the gas supply. Maximum altitude allowed for installation is 5,500 feet (1680 m). High Altitude Adjustment Based on the altitude of the installation site, reduce the manifold pressure specified in the “Technical Data” chart and as shown in the table below: Altitude Manifold Pressure Reduction Rate 0-2,000 ft 0% 2,000-3,000 ft 8% 3,000-4,000 ft 16% 4,000-5,000 ft 24% 5,000-5500 ft 32% 9 First Firing of the Furnace Start the furnace following the instructions given in the “Operating Instructions“. The initial pilot lighting may be difficult due to air trapped in the gas lines. During initial firing of the furnace, residual manufacturing grease will bake-out and smoke will occur which is not a health danger. To prevent nuisance and operation of fire alarms, ventilate the room for the first two hours of operation. Checking the Gas Inlet Pressure The gas inlet pressure can be measured by connecting a test gauge to the connection provided on the gas valve. (Figure 8 - A) Once installation is complete, the gas inlet pressure must be checked. The minimum gas inlet pressure must be as shown in “Technical Data”. After checking the gas inlet pressure, disconnect the test gauge and firmly tighten the screw of the gauge connection, then check for gas leaks. Checking the Gas Manifold Pressure The gas manifold pressure can be measured by connecting a test gauge to the connection provided on the gas valve. (Figure 8). The furnace comes set from the factory at the correct manifold gas pressure. After the installation is completed, the gas manifold pressure must be checked both in Hi and Lo input. The gas manifold pressure must be as shown in the “Technical Data”. Differences of plus or minus 0.1 in. w.c. are accepted. If the Hi or Lo gas manifold pressures are different from the values given in the “Technical Data” table, or are more than 0.1 in. w.c., shut off the furnace and contact a qualified service technician for correction. For instructions about adjustment of the manifold Hi and Lo pressures, see the “Servicing” section. After checking the gas manifold pressure, disconnect the test gauge and firmly tighten the screw of the gauge connection and then check for gas leaks from it.
