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.

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 CAN1-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 6 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 12.

●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 13.

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 service must be supplied at

7 ± 1.5 inch water column pressure (17.4 ± 4 mbar,

1.74± 0.37 kPa). An in-line pressure regulator may be required on Natural Gas models if the line pressure exceeds 8 water column inches (2.0 kPa) pressure with all gas appliances firing.

LIQUID PETROLEUM GAS (L.P.) service must be supplied at 11 ± 0.3 water column inches

(27 ± 1 mbar, 2.74 ± 0.07 kPa) with all gas appliances running (tumblers, water heaters, space heaters, furnace, etc.).

For converting Non-CE models from Natural Gas to L.P. Gas:

25 Pound – M4699P3

30 Pound – M4703P3

T30 – M4707P3

35 Pound – M4711P3
