No.Using a larger ring does not mean taller flame height. Generally a larger ring will broaden the flame and take away from the flame height. Most customers by the way think of large flame as being the height, not so much the width. To increase flame height when using a large ring the delivery of gas must be greater usually meaning larger gas orifice or valve. If delivery of gas cannot be increased, then “reducing” the fire ring size will increase the flame height.
