There is no adjustment for a Pilot Flame's Length on a Vent-free Gas Appliance. However, if you're using Natural Gas and it's a Natural Gas Heater, the normal length of the pilot flame is 2 to 2 1/2". If it's a Propane Gas Heater and the pilot flame is as long as previously stated, you probably have a pressure problem from your tank. Contact your Propane provider to have them check the pressure on their tank regulator.
