Venting Practices

Figure 20. Piping Suspension Guidelines

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

appliances, the venting system is likely to be too large to

properly vent the remaining attached appliances.

Conduct the following test while each appliance is operating

and the other appliances (which are not operating) remain

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 requirements

section.

CARBON MONOXIDE POISONING HAZARD

Failure to follow the steps outlined below for each

appliance connected to the venting system being

placed into operation could result in carbon monoxide

poisoning or death.
The following steps shall be followed for each appliance

connected to the venting system being placed into

operation, while all other appliances connected to the

venting system are not in operation.

DANGER

1. Seal any unused openings in the common venting

system.

2. 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.

Close all building doors and windows and all doors

between the space in which the appliances remaining

connected to the common venting system are located

and other spaces of the building. Turn ON clothes

dryers 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 operate at maximum speed. Do not operate a

summer exhaust 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.

6. After determining that each appliance connected to

the common venting system is venting properly, (step

3) return all doors, windows, exhaust fans, fireplace

dampers, and any other gas burning appliances to

their previous mode of operation.

7. If a venting problem is found during any of the

preceding tests, the common venting system must be

modified to correct the problems.

Resize the common venting system to the minimum vent

pipe size determined by using the appropriate tables in

Appendix G. These are in the current standards of the

National Fuel Gas Code ANSI Z223.1.

Figure 21.

1. In areas where piping penetrates joist or interior walls,

hole must be large enough to allow clearance on all

sides of pipe through center of hole using a hanger.
