I have a very slow gas leak in my house that I simply can't find.
The gas is leaking at a rate of 1.7 cubic feet per day (0.071 cubic feet
per hour) as measured by the meter.

Meters aren't for measuring gas leaks. Get your pipework and appliances
pressure tested with a manometer and that will tell you if you have a leak.

Does your boiler have a pilot light?
