Just had my gas water heater replaced by so called professionals but the inspector failed it because there is not enough space between the top of the heater and the right angled exit of the exhaust pipe. Mine goes out through the side garage wall just under the ceiling not through the roof. The new water heater is slightly taller then the new one. So I either need to vent the Boiler through the roof or lower the base.
Do you know the minimal required high of the base in Tracy California 95376.
the national fuel gas code states that the min clearence from any combustable surface is 18 inches
Is the top of the gas water heater considered a combustable surface?
What about the min high of the platform it sits on.
The vent tube goes up 8.5 inches then does a right angle out the side of the garage.
There is not 18 inches of space about the heater so sounds like this needs to go out through the roof?
if the heater sits on a platform it should be of a non combustable material it should sit on brick, tin, or concreet base
never carpet, wood, lenolium
the flue ( the pipe off the top ) should be tin unles going through a flamable wall then it should be doubble wall pipe with no less then a 1 inch gap of free space around it as it penetrates ( there are kits to keep it this way )
i have been in menny homes where it is not done this way and there are no problems but with out me being on site i can tell if yoour condition is safe or not
if a building inspector is telling you to change it i would follow his advice if you think he is being an ass you have a right to ask for the cheif inspector to give it a second review

if you are abel to go through the roof i think its the best
