It looks like a thimble with a small hole in the end for the gas to pass through.
Propane pilot light btu.
90 x 5 gallons 450 hours.
The pilot orifice is a small metal piece within the pilot assembly.
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.
It regulates the amount of gas supplied to the pilot flame.
Max btu 30 000 min btu 15 000 fuel type natural gas ignition electronic push button manifold pressure 5 in.
Note that in newer tank gas water heaters the pilot light is much smaller.
Noticed that the pilot light uses a signif amount of fuel.
Because the btu rating of natural gas is lower than propane the hole in the orifice is larger for natural gas.
90 000 1 000 90 0 so your pilot light will burn 1 gallon every 90 hours.
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.
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.
An average pilot light is about 1000 btu s.
Inlet gas pressure maximum 14 in.
