Removal of the Furnace from Common Vent

In the event that an existing furnace is removed from a venting system commonly run with separate gas ap- pliances, the venting system is likely to be too large to properly vent the remaining attached appliances,

Conduct the following test while each appliance is operat- ing and the other appliances (which are not operating) re- main connected to the common venting system. If the venting system has been installed improperly, you must correct the system as indicated in the general venting re- quirements section,

1 - Seal any unused openings in the common venting sys- tem.

_ Inspect the venting system for proper size and horizontal pitch, Determine that there is no blockage, restriction,

leakage, corrosion, or other deficiencies which could cause an unsafe condition,

3 - Close all building doors and windows and all doors be- tween the space in which the appliances remaining connected to the common venting system are located

and other spaces of the building. Turn on clothes dry- ers and any appliances not connected to the common venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they will oper- ate at maximum speed. Do not operate a summer ex- haust fan. Close fireplace dampers,

4 - Follow the lighting instructions, Turn on the appliance that is being inspected. Adjust the thermostat so that the appliance operates continuously,

5 - After the main burner has operated for 5 minutes, test for leaks of flue gases at the draft hood relief opening, Use the flame of a match or candle, or smoke from a cigarette, cigar, or pipe,

6 - After determining that each appliance connected to the common venting system is venting properly, (step 3) return all doors, widows, exhaust fans, fireplace damp- ers, and any other gas-burning appliances to their pre- vious mode of operation,

7 - If a venting problem is found during any of the preced- ing tests, the common venting system must be modi- fied to correct the problem,
