A work around for this on some tankless heaters is to use a spinning turbine in the pipe to detect that water is being used and to provide energy to ignite the gas.
Propane pilot light btu.
Inlet gas pressure maximum 14 in.
The pilot orifice is a small metal piece within the pilot assembly.
An average pilot light is about 1000 btu s.
It looks like a thimble with a small hole in the end for the gas to pass through.
Note that in newer tank gas water heaters the pilot light is much smaller.

Minimum for purposes of input adjustment 6 in.
You will consume slightly over a third of a gallon of propane per hour or 3 5 hours of burn time per gallon of propane.
Max btu 30 000 min btu 15 000 fuel type natural gas ignition electronic push button manifold pressure 5 in.
If your fireplace uses a pilot light for ignition that flame will consume about 600 btu per hour or 14 400 btu per day which equates to about a gallon of propane or about 4 pounds of propane every six days.
Dimensions in h x w x d height includes legs 24 09 in.
90 x 5 gallons 450 hours.
Because the btu rating of natural gas is lower than propane the hole in the orifice is larger for natural gas.
