Customer Question

I have a 1999 vintage Dacor SGB365 5 burner cooktop that currently runs on LP. I'm converting my home to Nat Gas and would like to know if there is a burner orifice conversion kit available. I know that the regulator valve needs to be switched from LP to NAT but cannot find any info about changing the burner orifice's or available kits to make the switch. The model sticker on the cooktop list both NAT and LP specs.
Thanks

Please be patient as many times we work with several customers at once.

Rich, there will probably not be any parts for this stove anymore, but if the BTU's are stamped on the stove for the individual burners, you should be able to figure it out as far as orifice size knowing the properties of natural gas. Then the orifices can be drilled out to the proper size.

BTU's are marked on the cooktop for both LP and NAT. 8500, 12500 & 14000 BTU's. Are you able to calculate the orifice size that will be required for NAT or point me in the right direction to calculate the orifice size?
Thanks
Rich

At 3.5 inches water column, the 8500 orifice should be drilled with a #53 drill bit, the 12,500 orifice should be drilled out with a #50 drill bit and the 14,000 orifice with a #48 drill bit.
