GAS PIPING
• Before connecting gas to the heater, check the supply gas and supply pressure: match the information on the
rating plate of the heater.
• The gas meter and service must be sufficiently large to supply gas to the connected building gas load including
the heating equipment and any other gas fired equipment. Additionally, the gas distribution piping must be
designed according to National standards and Codes of Practice in the destination country. Generally, (low
pressure) systems designed with a maximum 1.25 mbar (½" W.C.) total pressure drop meet this requirement.
• Gas supply pipe sizing must be in accordance with the National standards and Codes of Practice in the
destination country. Minimum size to be 12.7 mm (½") bore.
• Before connecting burners to the gas supply system, verify that high pressure testing of the system has been
completed. Failure to do so may expose the burner components to damaging high pressure, requiring
replacement of key components.
•
Pipe joint compounds must be resistant to the action of liquefied petroleum (LP) gases.
Flexible gas connectors of approved type must be installed without sharp bends, kinks or twists. Failure to install
the gas connection in the approved manner will result in a hazardous and potentially deadly situation due to the
movement of the heater in the normal course of operation
If possible, the regulator should be mounted outdoors. In the case that it is not possible, then the regulator’s vent
must be vented outdoors using vent line the same diameter as the vent opening.
In any indoor animal confinement building, consideration must be given to making sure the heater is located away
from the livestock so that livestock cannot knock the heater, tear it loose from its mounting, or damage the heater or
its gas supply line in any way. Make sure you observe and obey minimum clearance distances to combustible
materials as stated in the specification section of this owner’s manual and on the heater itself.
Install a manual shut-off valve in the gas piping to each heater. This will allow service of individual heaters without
having to shut down the entire gas supply system.
A sediment trap must be installed in the supply line in the lowest spot prior to the heater. The trap length should be
at least (3) inches long.
