An average pilot light is about 1000 btu s.
Propane pilot light btu.
The pilot orifice is a small metal piece within the pilot assembly.
90 000 1 000 90 0 so your pilot light will burn 1 gallon every 90 hours.
Note that in newer tank gas water heaters the pilot light is much smaller.
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.
Inlet gas pressure maximum 14 in.
Dimensions in h x w x d height includes legs 24 09 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.
Max btu 30 000 min btu 15 000 fuel type natural gas ignition electronic push button manifold pressure 5 in.
Because the btu rating of natural gas is lower than propane the hole in the orifice is larger for natural gas.
Noticed that the pilot light uses a signif amount of fuel.
450 24 hours 18 75 days.
It looks like a thimble with a small hole in the end for the gas to pass through.
Minimum for purposes of input adjustment 6 in.
It regulates the amount of gas supplied to the pilot flame.
