Help Center - Glossary of termsDrill SizeUnder construction Drill size, or wire gauge drill size, is a term used to describe the diameter of the hole "drilled" through an orifice. Gas passes through this hole on its way to the burner. The size is expressed as a number, the drill number, that indicates which size drill is used to bore the hole. For example, a #48 drill will create a hole with a diameter of 0.0768 inches.The correct orifice hole size is determined by a number of factors including the type of gas (LP is typically smaller than natural gas in a given situation), the BTU rating of the burners, gas pressure at the orifice, and BTU value of the gas. Refer to your owners manual or consult with a qualified gas technician to determine the exact size required for your grill. If you would like us to drill the orifice(s) for you, there is a single $15 fee for this service, which will be added to the order when processed. Please tell us the number of burners in your grill and the total BTUs of your grill (less side burner and rotisserie burner, if any). BTU rating information can usually be found on the grill's CSA certification tag, located somewhere on the grill. Please furnish this, along with any other information you deem relevant, in the Message to CLA box during checkout. |
