CAUTION
Some soap used for leak testing is corrosive to certain types of metals.
Clean all piping thoroughly after completing the leak check.
CAUTION
Never leave an opened manual air vent unattended.
In the event that an opened vent is left unattended, water damage could occur.
CAUTION
The presence of chlorides and/or sulphur in the combustion air or fuel
will negatively impact the heat exchanger and void the warranty.
The gas supply pipe terminates in a 28 mm copper pipe connection on each 250 model. Common
gas supply pipe sizes for connection to multiple boiler modules are available on request from Fulton.
1. A minimum working gas pressure of 6.5 mbar must be available at the boiler inlet with the
boiler ring.
2. Fit a gas supply pipe at an appropriate size in order to limit the pressure drop between the
meter outlet and connection to the boiler(s) to 1 mbar (100 Pa) max.
3. All gas supply pipework must be independently supported.
4. The boiler and all gas piping connections must be pressure-tested and checked for leaks
before being placed into service. Test with compressed air or inert gas if possible.
5. The boiler must be disconnected at the boiler manual shutoff valve (located near the end of
the supplied gas train at the front of the boiler) from the gas supply piping system during any
pressure testing of the system at pressures in excess of 35 mbar (3.5 Pa).
6. Gas piping must be installed in accordance with all relevant gas codes and any other local
codes which may apply.
7. The pipe and the ttings used must be new and free of dirt or other deposits.
8. After gas piping is completed and before wiring installation is started, carefully check all
piping connections, (factory and eld), for gas leaks. Use a soap and water solution.
