h) The gas pipe, flexible hose and connections must be self-supporting. The gas pipe work must not bear any
of the weight of the heater or any other suspended assembly.
i)
This appliance is equipped with a fast-opening, combination gas valve. The maximum supply pressure to
the appliance is 60 mbar. If the line pressure is more than the maximum supply pressure, then a second
stage regulator which corresponds to the supply pressure must be used
j)
After all gas connections have been made, make sure the heater and all gas outlets are turned off before
the main gas supply is turned on slowly. Turn the gas supply pressure on and check for leaks.
k) If a 2nd stage regulator is used, the ball valve before the heater in the supply line must be closed when
purging the gas lines to prevent gas seeping through it. If initial gas pressure is higher than 60 mbar the
redundant combination gas valve is designed to lock out. Pressure build-up in the supply lines prior to the
heater must be released before proper heater operation.
l)
High gas pressure regulators need to be installed upstream of flexible gas lines.
The entire gas supply system must be checked for leaks prior to heater operation. Do not use an
open flame of any kind to test for leaks.
