Viking V CM Series Installation, Operation & Owners Manual page 7

Gas Supply
The local gas authority should be consulted at the installation planning stage in order to establish
the availability of an adequate supply of gas and to ensure that the meter is adequate for the
required flow rate. The pipe work from the meter to the appliance must be an appropriate size.
(See Chart at end)
All fixed (non-mobile) appliances must be fitted with an accessible upstream gas shut off valve as
a means of isolating the appliance for emergency shut off and for servicing. A union or similar
means of disconnection must be provided between the gas-cock and the appliance.
A manually operable valve must be fitted to the gas supply to the kitchen to enable it to be
isolated in an emergency. Wherever practical, this shall be located either outside the kitchen or
near to an exit in a readily accessible position.
Where it is not practical to do this, an automatic isolation valve system shall be fitted which can
be operated from a readily accessible position near to the exit.
In locations where the manual isolation valve is fitted or the automatic system can be reset this
notice must be posted:
"ALL DOWNSTREAM BURNER AND PILOT VALVES MUST BE TURNED OFF PRIOR TO
ATTEMPTING TO RESTORE THE SUPPLY. AFTER EXTENDED SHUT OFF, PURGE
BEFORE RESTORING GAS"
Gas Supply Notes
Before assembly and connection, check gas supply.
•
The type of gas for which the unit is equipped is stamped on the data plate, see locations
chart. Connect a unit stamped "Natural" only to natural gas and stamped "Propane" only
to propane gas.
•
If it is a new installation, have the gas authorities check the meter size and piping to
assure that the unit is supplied with the necessary amount of gas supply and pressure to
operate the unit(s).
•
Make certain new piping and connections have been made in a clean manner and have
been purged so that piping compound, chips, etc. will not clog pilots, valves or burners.
Use pipe joint compound approved for natural and liquefied petroleum gases.
