Join the WxTV crew as we dive deep into a clean, tune, and test of a gas furnace. In Part 1 of this series, our master plumber Mike Campbell guides us through the initial inspection, clocks the gas meter, and calculates proper combustion air.

Nice Video well done ...but I didn't get that if we are getting around 110,000 btu/h instead of 1,38,000 because of above sea level calculations we should use 110,000 btu/h for return duct sizing too and one other thing even if we are get 96,000 btu/h (70% of 1,38,000) we need 192 sq ft insead of 96 sq ft of return duct.

Did he measure the height? Maybe that was done off-camera. With an 8ft ceiling height, a 430 sq ft space is needed to suit the code he mentions in the video. That would require a room about 20X21.5 or 16X27, etc. That kind of size isn't uncommon for a basement unit, however, if the basement has been remodeled or recently finished, you may have to get fresh air brought in like he suggested in the video to maximize performance.

Combustion air...if it’s open to the room they enter in from you can use that room for calculating..if it doesn’t have a door.

the gas meter reading is 1 cubic feet in 25 sec, it means 2.4 cubic feet per min and 144 cubic feet per hour, right? the heat value of natural gas is 1000 btu/cubic feet, therefore the actual input of gas furnace is 144,000 btu/hour. But why the guy said the actual input is 124,500 btu/cubic feet at 8:30??

+XIAO JIE Same thing i was thinkn, tryn to figure out where the 124,500 came from, Good that someone else caught that. i got 148,320 bth/hr , used 1 cu-ft=1030 btu. I do HVAC and repair furnaces all the time at Shepherd ENG Heating Cooling and Refrigeration. look it up

Needs two square in. for 1K BTU's of output. At 70 percent efficient output of 96k BTU you need at least 192 Square in of duct. With current dimensions of 230 Sq in of duct, its approaching its limits.

The exhaust pipe takes out a lot of heat through the chimney. What is the purpose of the pipe and would it be OK to block it?

If I followed your math correctly, 70% of 138000 is approx 96000. But you said you needed 2 sq in per 1000, so wouldn't it be 96 x 2 = approx 193 sq in?

And he has 230 Sq in of return air. so, it more than it is supposed to which is a good thing.

Also, shouldn't it be even less because of the altitude meaning you lose ~20%?

Duct tape on the flue! How about the entire flue connectors being illegal, you can't use galvanized pipe for flue contactors, they need to be B-vent, it would give you a 1" clearance. But the international mechanical code is a minimum of single wall aluminum vent connects. I agree the earlier comment that they should change that to a 95% furnace. 70% efficient you’re lucky if it would be 60%, with a belt drive, Installed in 1976, Can you say possible heat exchanger heat cracks. Replace it!

denny3161 yeah...many full basements don’t measure up enough for proper combustion air..must add outside air..best with a 2 pipe flue furnace 95% which takes combustion air from the outside.

Or you could get rid of that inefficient heap of junk,and put in a direct vent 2 stage, variable speed 95% furnace and quit pouring all your heating dollars out the chimney! Combustion air problem solved! .... Just make sure you dont need a chimney liner ;)

Whats better than bringing a combustion air into that room is STOP USING A NATURAL DRAFT APPLIANCE BECAUSE ITS NOT 1950!!!! Seriously, especially what I see there looks like its from the late 70s. How about some direct vent condensing gas appliances, its 2013 afterall
