Gas Connection Planning
Loring roasters can be fueled by either natural or propane gas. The gas supply pressure is the
same for each roaster, but the gas volume is different between them.
Gas connections to the roaster must be made by a licensed contractor in accordance with
all applicable local and regional regulations regarding installations of this type. It will be
the responsibility of the contractor to not only be sure that the connections meet local code
guidelines but also will supply the BTU/HR demand of the roaster. Improper connection type
and pipe size will cause the roaster to perform poorly, potentially rendering it unusable. The gas
contractor will be able to verify the potential BTU/HR of the supply system he installs based on
pipe size, length, path and available pressure.
Provided on the utility tray of the roaster is an NPT pipe fitting, which is the inlet to the burner
assembly. There is a shutoff valve provided at the roaster as well as a gauge for monitoring the
incoming gas pressure.
A separate regulator may be required to feed the roaster if the upstream pressure is too high.
Multiple fittings or a long path may reduce flow, which must be taken into consideration.
It is vital to the proper operation of the roaster as well as the safety and legality of the system
that proper care and planning go into the gas supply system.
Gas requirements
Caloric Content
In order to provide adequate roasting performance, Loring roasters require that the gas supply
maintain a minimum caloric level.
•
Natural gas: 1000Btu/ft^3 (37 MJ/m^3) or greater
•
Propane: 2500Btu/ft^3 (93 MJ/m^3) or greater
This is critical to the proper operation of the roaster. Confirm with your gas supply company that
the minimum caloric content is supplied and constant.
