Gas Piping第 91 / 120 题
On which of the following appliances does the IFGC NOT require a sediment trap ahead of the appliance control valve?
a.A 100,000 Btu/h forced-air furnace
b.A 40 gal storage water heater
c.A gas-fired boiler
d.A clothes dryer
解析
The IFGC exempts illuminating appliances, ranges, clothes dryers, decorative appliances, gas fireplaces and outdoor grills from the sediment trap requirement; a clothes dryer is on that list. Furnaces, water heaters and boilers all have gas control valves that must be protected, so each requires a trap located as close to the appliance inlet as practical.
