§         Treasury Report given by Sarah Aguilar

§         Venting of Sumps and Ejectors- Mr. Bud Starmer of the City of Palo Alto and the chapter members present discussed this subject in length on how different jurisdictions are interpreting this section in the codebook and handling it out in the field.   The section (710.10) vent is to extend through the roof separately unless the AHJ approves otherwise beforehand. The combining of a sump or receiving tank vent with other vent pipes is not allowed unless a request is made to do so before the piping is run.  Furthermore the section also refers to the venting of the sump, which is based on the fixture unit values of the fixtures wasting INTO the sump, not the size of the drain, which is determined by the GPM discharge FROM the pump.

Committee Reports

Discussion

·         The delivery capacity of each tankless water heater shall be determined by the manufacturer's listing submitted at time of application.. TWH venting shall comply with the UMC venting requirements for Category III & IV appliances and for positive pressure venting.  A BTU line diagram is to be submitted to verify that existing house gas piping is adequately sized for the increased load. Combustion Air shall comply with current UPC (Section 507, Table 5.2) requirements.

·         The AHJ may approve of replacement furnaces with reduced clearances if the conditions of the listing are met.  Some Chapter members require manufacturers installation instructions submitted at time of application; others only require the instructions to be on site at time of inspection.
