INSUZ PR Model Technical Specifications
The technical table provides a detailed overview of the performance and operational parameters of the INSUZ PR series boilers.
This table includes essential technical data such as nominal capacity, efficiency rates, and operating pressure values. When selecting a burner and designing the piping system, factors like combustion chamber back pressure and water-side pressure losses should be considered. Additionally, maximum operating pressure and water capacity play a crucial role in system design.
To optimize your boiler’s performance, pay close attention to the technical specifications when making a selection.

Burner Connection Details
⚠️ The Burner Connection table is only visible on desktop devices. It is not supported on mobile devices.
1- Boiler, 2- Boiler front door, 3- Burner mounting flange plate, 4- Burner, 5- Thermal insulation between the burner flame head and door, 6- Viewing Glass Cooling Air Supply Connection, K – Door Refractory Thickness, Lr – Burner flame head length, L3 – Front Door Opening Diameter Dr – Flame head diameter
⚠️ Lr > K ⚠️ Lr must be greater than K to ensure proper burner positioning.
For proper burner installation, the flame head length (Lr) must be greater than the cover insulation thickness (K). Otherwise, the burner cannot be properly positioned in the combustion chamber. Before ordering a burner, share these values with the burner manufacturer to ensure a correct selection.
