6) Fires shall be of wood, wood pellets or charcoal. Gas and electric heat sources shall not be permitted for cooking or holding.
The above is taken from the current rules. There is nothing ambiguous in this rule and to ask for a rep advisory to clarify is somewhat asinine. Heat lamps which, typically run on electricity, serve only on purpose in the food industry, they provide an open air heat source for holding food at an elevated temperature.
There are so many ways for a person to skew the rules to gain a perceived edge that we would need a rule book 6 inches thick just to cover a part of them. This is a sport or hobby or whatever that is basically a gentleman’s agreement enforcement of the published rules. If someone wants to use a heat lamp to hold their meat during prep then do so in the trailer with the door closed. You will be the only one to know you cheated. If you can live with that, then go for it but remember, if you are caught, the gentleman’s agreement stipulates the punishment.
