UMC 801 & 803.1Vent is suitable for type of fuel (B or L)............................... UMC 801Vent is properly sized. (KNOW THE GAMMA TABLES:All venting systems in PPRBD jurisdiction are sized perthe July 1991 revised edition of the Gamma Tables ormanufacturer’s specs. Any offset that takes the pipeout of line and back again, regardless of fitting, is anoffset and constitutes a 20% reduction in the maximumbtu capacity of the common vent. If the vent offsets lessthan the diameter of the pipe, (you can see through it),no reductions are taken. A manifold system includingthe horizontal tee or wye and one 90 o elbow to thevertical causes a 10% reduction in the btu capacity ofthe common vent. See footnotes: 1 - 6, 9, 19, 21, 22,20 and 31 in the Gamma Table booklet.(Continued this page)●❏❏❏❏❏❏●❏❏❏❏❏❏❏❏❏●❏❏❏❏❏❏❏❏❏❏❏❏●❏❏❏❏❏❏❏❏❏❏❏❏❏❏VENTVent clearance..................................................................Vent connector has adequate pitch...................................Vent offsets.......................................................................Joints mechanically secured................................................Vent connector clearance to combustible.............................Horizontal portion of connector is run correctly.GAS PIPING/INSIDELine is sized properly, overall length/btu load.
