Gas Requirements

WARNING

To reduce the risk of fire or explosion, DO NOT CONNECT THE GAS LINE TO THE TUMBLER IF THE GAS SERVICE IS NOT THE SAME AS THAT SPECIFIED ON THE TUMBLER SERIAL PLATE! It will first be necessary to convert the gas burner orifice and gas valve. Appropriate conversion kits are available.

W060

IMPORTANT: Any product revisions or conversions must be made by the Manufacturer’s Authorized Dealers, Distributors or local service personnel.

IMPORTANT: The tumbler 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 piping system at test pressure equal to or less than 0.5 psig

(3.45 kPa, 34.5 mbar).

IMPORTANT: The tumbler and its manually operated appliance gas 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 (3.45 kPa, 34.5 mbar).

IMPORTANT: The installation must comply with local codes or, in the absence of local codes:

•with the latest edition of the “National Fuel Gas Code,” ANSI Z223.1/NFPA 54 in the U.S.A.,

•with CAN/CSA-B149.1 or Natural Gas and Propane Installation Code in Canada,

•and Australian Gas Association/Australian L.P. Gas Association requirements in Australia.

Obtain specific gas service pipe size from the gas supplier. Refer to Table 7 for general pipe size.

The following must be furnished and installed by the customer for the gas service line to each tumbler. Refer to Figure 13.

•Sediment traps

•Shut-off valves

•Supply pressure taps

It is important that equal pressure be maintained at all tumbler gas connections. This can best be done by installing a one inch (25 mm) pipe gas loop. Refer to Figure 14.

WARNING

To reduce the risk of fire or explosion, if the tumbler is to be connected to Liquefied Petroleum (L.P.) gas, a vent to the outdoors must be provided in the room where the tumbler is installed.

W062

NATURAL GAS line pressure must be maintained at

6.5water column inches (1.62 kPa) with no less than 5 water column inches (1.24 kPa) and no more than 10.5 water column inches (2.61 kPa), with all gas appliances running (tumblers, water heaters, space heaters, furnace, etc.). An in-line pressure regulator may be required if the line pressure exceeds 8 water column inches (2.0 kPa) with all gas appliances running.

LIQUID PETROLEUM GAS (L.P.) line pressure must be maintained at 11 water column inches (2.74 kPa), with no less than 10 water column inches (2.49 kPa) and no more than 13 water column inches (3.23 kPa), with all gas appliances running (tumblers, water heaters, space heaters, furnace, etc.).
