Beech Ovens Page 86 RND-REC-RGO Manual (R1) 28/07/2011 (C) Confidential and Proprietary Preheating with Gas Before the oven can be used for cooking it must undergo a Preheat or curing stage. This is a gradual, low flame stage designed to thoroughly “warm” the oven prior to use. This is common practice for all ovens and must be done to ensure that the materials in the oven are slowly “cured” to reduce cracking. The oven should be preheated for at least 72 hours.
Beech Ovens Page 87 RND-REC-RGO Manual (R1) 28/07/2011 (C) Confidential and Proprietary Preheating with Wood As mentioned in Preheating with Gas, before the oven can be used for cooking it must undergo a Preheat or curing stage. This is best done by making a fire just as you would build any fire for a barbeque. The best wood to use is anything hard, dry and dense which is untreated and without paint. To start the fire follow the following steps: 1.
Beech Ovens Page 88 RND-REC-RGO Manual (R1) 28/07/2011 (C) Confidential and Proprietary Adjustments for Normal use After the three (3) days of preheating are completed, some adjustments must be made to allow the oven to function normally.
