Natural Gas Installation Specifications
BTU minimum requirements of the Loring S15 roaster.
•
S15 Falcon requires 130,000 BTU/hr (33K kcal/h) gas supply
BTU delivery is based upon minimum 4” water column (WC) (1.0 kPa) dynamic flow with a
maximum of 7” WC (1.7 kPa).
Components of a Natural Gas System
• Utility Company supplying Natural Gas to your building
•
Gas Regulator(s)
• Gas Meter
• Plumbing to Appliances
Recommended Gas Supply System:
Gas supply to the outside of the building is always higher than the working pressure and needs to
be regulated according to the specific demand.
The distance from the meter to the roaster will determine if more than one regulator is needed. If
a first and second stage regulator is required, typically the first regulator is set for 2 PSI and the
second regulator is set for working pressure of 4” to 7” WC (1.0 to 1.7 kPa).
Meter and regulator must be designed to handle 130,000 BTU/hr (33K kcal/h).
Second Regulator or Working Pressure Regulator must be less than 100 feet (30.5 m) and more
than 10 feet (3 m) from the roaster to reduce higher pressure to the minimum working pressure of 4”
WC (1.0 kPa) to maximum 7” WC (1.7 kPa).
Recommended Natural Gas Working Pressure Regulator: Sensus 143-80-2 with ½” (1.3 cm)
orifice and Blue Spring with appropriate pipe inlet and outlet size. After installation, adjust working
pressure of 5” WC (1.2 kPa) to 8.5” WC (2.1 kPa).
