Ratings shown are for sea level applications only. For altitudes above sea level, the SVF boiler requires no modifications; it automatically derates itself by
approximately 4% per 1,000 ft above sea level For elevations over 2,000 ft , see the High Altitude section on page 114 for required control parameter changes The
length of the vent and air piping will affect the maximum input. See Table 27 below for derate % according to vent and air piping length.
2
Net AHRI ratings are based on net installed radiation of sufficient quantity for the requirements of the building, and nothing needs to be added for normal piping and
pickup Ratings are based on a piping and pickup allowance of 1 15 An additional allowance should be made for unusual piping and pickup loads
3
Thermal efficiency is based on AHRI testing procedure AHRI 1500.
4
SVF boilers can be direct vent or direct exhaust vented, either through a side wall or through the roof, as instructed in this manual and compliant with all local codes
SVF boilers require special venting, consistent with Category IV boilers For Category II boiler systems, see pages 30 to 33 Use only the vent materials and
methods identified in this manual.
5
The values are for the stack flow rate at the maximum firing rate for the given boiler. The values can vary, depending on the location of the installation and the
operating conditions

Determine vent/air piping equivalent length (ft.) - Use the length for L in the equations.
% Derate = L x 077
Example: If L = 75 ft.,
Derate % = 75 x .077 = 5.775
