If uncertain about which item should be used as reference for clearance, check with the local inspector to ensure compliance. *Note: Many of the drawings and images shown in this manual are of Miura’s LX- 300 model which can be installed with zero side clearance between two or more units.
*Note: The above table is minimum requirements from the National Board in the boiler room. The total cross- Inspection Code and Miura recommendations; however, check local codes to sectional area of such openings shall ensure compliance.
It is important to ensure that the equipment pad is level prior to boiler installation. Miura recommends using a bolt which is 3” in length or greater that is spaced 6” or more from the edge of the equipment pad as shown in the diagram.
For installations where a deaerator tank is used and the b. Miura boilers can come up to full steam pressure in 5 minutes condensate return is to exceed 50% of boiler steam capacity, a and thus using a slightly oversized steam valve on the first separate condensate surge system is recommended.
Miura is unable to provide a standard procedure for lifting the boiler. It is recommended that all Miura boilers be lifted from above by using the provided lifting lugs on each boiler. This can be done by either using a crane, forklift, or other device deemed suitable.
