Projected snow line with regard air intake in MA

Joe@buderus_2

I believe Mass has some "unique" codes that are above the normal about direct vent terminations. As stated in previous post check with the local inspector.

Projected snow level with regards air intake in MA

I am installing a Prestige 110 mod/con boiler in MA. The vent supplement for the boiler states that the air intake needs to be 12" above grade or projected snow line. Does MA plumbing/gas code have a projected snow level(i have never see it)? Due to buidling layout the air intake can only be a maximum of 24"above grade.

Thanks,

WJP,

Check with the local inspector. I've heard everything from 18-24" as "hard facts". Let the guy who makes the decision make the call.(24" seems more than enough to me... If the unit is making hot water, it will run at least a few times a day in winter, but home owners do funny things with shovels and snowblowers when they need to get out of the driveway.) Save yourself the extra work! Chris

MA code

The inspectional services department is to follow "the Mfg. reccomendations". This means 12" above grade is acceptable. No other information is given to MA inspectors. This leaves the door wide open to interpretation of what's right & wrong. A reasonable asumption is that more than one foot of snow can fall in Mass. I'd bring the vent termination as high as 7' ft if I could but the code can NOT make me raise it above 12" inches. FACT. Been there. Done that.

Thanks, for the info. My vent height is fine. It was the air intake that was in question. After talking with an inspector, the 12" above grade for the air intake is good(mine is set at a max height of 24"). MA has not established a projected snowfall at this stage of the game. I will put up the code approved sign "Keep gas vent clear of all obstructions" and a co detector. Done.
