Frequently Asked Questions - CB36-250G Blodgett
What gas types can be used with the CB36-250G?
The Blodgett CB36-250G is designed to operate on natural gas or propane. The unit comes pre-set for natural gas but can be converted in the field using a conversion kit. Always check the gas type before installation to ensure proper burner operation.
What is the steam output of the CB36-250G?
The CB36-250G produces up to 250 pounds of steam per hour at a working pressure of 10-15 PSI. This makes it suitable for supplying steam to multiple cooking appliances such as steamer cabinets and kettles in a commercial kitchen.
How do I install the CB36-250G?
Installation must be performed by a licensed plumber and gas fitter. Connect the water supply to the 3/4 inch NPT inlet, gas to the 1 inch NPT inlet, and the steam line to the 2 inch NPT outlet. Provide adequate ventilation and clearances as specified in the manual.
What maintenance does the CB36-250G require?
Daily blowdown is required to remove sediment from the boiler vessel. Periodic descaling with a commercial descaler is recommended to prevent scale buildup. Inspect the water level control and safety valves monthly, and check gas connections for leaks annually.
How do I clean the generator?
Clean the exterior with a damp cloth and mild detergent. Do not use abrasive cleaners on the stainless steel surfaces. For internal scale, follow the descaling procedure in the manual, using a food-safe descaler.
What safety devices are included?
The CB36-250G features a low water cutoff that shuts the burner off if water level drops below safe limits, a pressure relief valve for overpressure protection, a flame failure switch to stop gas flow if the flame goes out, and a gas pressure regulator to maintain proper gas inlet pressure.
What water quality is needed?
Use softened water to reduce mineral buildup. Water hardness should be below 5 grains per gallon. Reverse osmosis or deionized water is not recommended as it can be corrosive to the boiler vessel.
How do I adjust the gas pressure?
Gas pressure should be adjusted by a qualified technician using a manometer. The manufacturer's manual provides the correct pressure settings for both natural gas and propane. Incorrect pressure can damage the burner or cause unsafe operation.
What are the electrical requirements?
The CB36-250G requires a 120V/60Hz electrical connection for the control system and ignition. It draws less than 5 amps. A dedicated grounded outlet is recommended.
Why is steam pressure low?
Low steam pressure can be caused by insufficient gas supply, blocked burner ports, faulty water level control, or scale buildup. Check the gas inlet pressure and ensure all valves are fully open. Clean the burner and descaled the boiler to restore performance.
