Common Venting Connector Rule

Recommended Posts

Hi All,

Quick like a bunny. I'm having a senior moment and can't find the rule in the code that says a water heater vent connector to a common vent must enter higher than the connector from the furnace. Anyone know that one is lcoated off the top of your heads?

ONE TEAM - ONE FIGHT!!!

NY mechanical code says:

803.7 Connectors serving two or more appliances. Where two or more connectors enter a common vent or chimney, the smaller connector shall enter at the highest level consistent with available headroom or clearance to combustible material.

Was it this one?

From the 06' IRC

G2427.10.4 (503.10.4) Two or more appliances connected to a single vent. Where two or more vent connectors enter a common gas vent, chimney flue, or single-wall metal pipe, the smaller connector shall enter at the highest level consistent with the available headroom or clearance to combustible material.Vent connectors serving Category I appliances shall not be connected to any portion of a mechanical draft system operating under positive static pressure, such as those serving Category III or IV appliances.
