Miura Steam Boiler LXL-200

Warning: No work other than that clearly indicated below is to be carried out on the boiler. Failure to observe this precaution may result in injury.

Warning: Water in supply lines for boilers connecting to a deaerator or hot water tank is extremely hot. For this reason, you should wait until the tank water has sufficiently cooled down (at least two hours after boiler shutdown) before performing this work. Failure to observe this precaution can result in burns and other injuries.

Turn off the breaker for the boiler’s main power. Confirm that the steam pressure gauge is reading 0 PSI. If this is not the case, stand by until the pressure reading drops to zero.

Warning: Never operate the breaker for the boiler’s main power supply with wet hands. Failure to observe this precaution may lead to electric shock and have other undesirable consequences.

Open the blowdown valve for the feed water tank.

When the discharge of water ends, close the feed water tank’s blowdown valve.

Warning: Water in the feed-water tank for the boiler connecting to a deaerator or hot water tank is extremely hot. Wait until the boiler’s water supply lines have sufficiently cooled down (at least two hours after boiler shutdown) before performing this work. Failure to observe this precaution can result in burns and other injuries.

Turn off the breaker for the boiler’s main power. Confirm that the steam pressure gauge is reading 0 PSI.

Warning: Never operate the breaker for the boiler’s main power supply with wet hands. Failure to observe this precaution may lead to electric shock and have other undesirable consequences.

Confirm that the main feed water valve is closed.

Open the boiler blowdown valve and carry out boiler-water blowdown.

Warning: Be sure to always carry out boiler-water blowdown before cleaning the feed water strainer. If reverse flow of boiler water were to occur during this procedure, it could result in burns or other injury.

When the discharge of boiler water has stopped, close the boiler blowdown valve.

Open the feed water pump’s air bleed valve. This action releases pressure from the feed water piping.

Warning: No work other than that clearly indicated below is to be carried out on the boiler. Failure to observe this precaution may result in injury.

Using the boiler’s gas pressure gauge, confirm whether the gas is pressurized to the required range (i.e., 3 to 5 PSI)

If the reading on the gas pressure gauge is not within the required range, immediately shutdown the boiler

If the reading on the gas pressure gauge is not within the required range, contact a MIURA sales office or your local dealer for further instruction.

Warning: No work other than that clearly indicated below is to be carried out on the boiler. Failure to observe this precaution may result in injury.

Warning: As all parts of the boiler remain at a high temperature for some time after shutdown, you should allow sufficient time for cooling down before performing this work. Failure to observe this precaution can result in burns and other injury.

Before attempting to clean the UV sensor’s protective glass, be sure to always receive instruction from MIURA maintenance personnel and to fully familiarize yourself with the process involved.

Turn off the breaker for the boiler’s main power.

Warning: Never operate the breaker for the boiler’s main power supply with wet hands. Failure to observe this precaution may lead to electric shock and have other undesirable consequences.

Remove the mounting screws from the phototube base.

Using a soft cloth, wipe all soot from the glass at the bottom of the UV sensor’s base.

Reassemble and replace the sensor in its original condition and position.
