6.2 Gas Control Trains - All models include gas control trains with the following components: main manual shutoff valve, two safety shutoff valves and pressure regulator. These components may be separate or two or more may be combined in a common housing. Caution: Do not adjust or remove any screws or bolts on gas train control components which are sealed with a red or blue colored compound. Doing so will void all approvals and warranties. 6.3 Inlet Pressure - Measure at the inlet press
