Gas Connection - PENSOTTI PCH 50B-H Instruction Manual

3.8 Gas Connection

3.8.1 Gas Piping Guidelines
Follow all local codes and/or the most recent edition of the National Fuel Gas Code (ANSI Z223.1/NFPA 54) in
the USA or the Natural Gas and Propane Installation Code in Canada (CAN/CSA B149.1).
3.8.2 Gas Supply Lines Pressures
The minimum and maximum inlet gas pressures are Natural Gas Min. 7.00"WC – Max. 14.00"WC. and
Propane Gas Min. 11.00"WC – Max. 21.00"WC.
Gas pressures over and above the specified range will result in adverse performance and
dangerous operating conditions; any damage resulting from extreme gas supply pressures will not
be covered by the limited warranty.
Until pressure testing of the main gas supply line is completed, ensure the gas line to the
PENSOTTI Boiler is disconnected to avoid any damage to the boiler.
The appliance and its individual shut off valve must be disconnected from the gas supply piping
system during any pressure testing of that system at test pressures in excess of 0.5 psi (3.5 kPa)..
The appliance must be isolated from the gas supply piping system by closing its individual manual
shut-off valve during any pressure testing of the gas supply system at test pressures equal to or less
that 0.5 psi (3.5 kPa).
The gas appliance and its gas connections must be leak tested before placing the appliance in
operation. Leaks can be found by using a gas leak detection device or by applying soapy water
to all gas fittings. Should bubbles occur, tighten those connections and re-test.
Always purge the gas line for any debris before connecting to the boiler gas inlet.
Never use an open flame to test for gas leaks as property damage, personal injury or death could result.
The maximum inlet gas pressure must not exceed the valve specified by the manufacturer and that the
minimum valve listed as for the purposes of input adjustment.
The connection to the gas supply must be carried out by professionally qualified personnel in accordance with
the relevant standards.
■ Check the internal and external seals of the gas supply system.
■ A gas shut-off valve and sediment trap must be installed upstream of the appliance .
■ Before starting up the boiler, make sure that the type of gas corresponds to that for which the appliance has
been set-up.
■ The gas supply pressure must be between the values reported on
the rating plate.
■ Conversion of the appliance from natural gas to LPG or vice
versa must be carried out by qualified personnel.
■ The power supply cable must be replaced by a qualified
electrician. If the cable is damaged in any way, switch off the
appliance and have the cable replaced by a suitably qualified
electrician.
When using an electrical appliance, a few fundamental rules
must be observed: Do not touch the appliance with damp or
wet parts of the body or when barefoot. Do not pull on the
electric wires.
Do not allow the appliance to be used by children or anyone
unfamiliar with its operation.
