Once the lineup cards are submitted (approx. 5 minutes before game time), the umpires take control of the field and the crew chief becomes the person who decides whether to delay or postpone a game (and if/when to restart).
A firewood moisture meter can be used to determine the moisture content of your firewood, but are they a necessity or just a novelty? Seasoned firewood is considered to have a moisture content of 20% or less.
Ash content is measured as a percentage of weight and should be at most 1%. In other words: when you burn a 40-pound bag of pellets, you should have less than 6 oz. of ash (or about 3/4 cup). The less ash you have, the less often you have to clean your stove. Moisture content is also measured as a percentage. A premium pellet must have less than 8% moisture, but higher quality fuels will have 6.5% or less. If the moisture content of your pellets is too high, you may notice that your fuel takes longer to ignite when you first fire up your stove.
