GAS CONNECTIONS (Gas Drying Tumblers)

Before connecting gas piping to tumbler, make certain gas service is same as that specified on nameplate (near gas connection), Page 5.

NATURAL GAS service must be supplied at 6¹⁄₂ ± 1¹⁄₂ inch water column pressure (1.62 ± .37 kPa).

L.P. GAS service must be supplied at 11 ± .3 inch water column pressure (2.74 ± .07 kPa).

If gas service is not same as that specified, DO NOT CONNECT THE GAS LINE TO TUMBLER! It will first be necessary to convert gas burner orifice and gas valve.

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

￿WARNING

Purge air and sediment from gas service line before connecting it loosely to tumbler. Purge remaining air until odor of gas is detected, then tighten connection.

Use pipe compound, resistant to actions of L.P. gas, on all pipe threads.

￿WARNING

Check all pipe connections, internal and external, for gas leaks using a soapy solution. To reduce the risk of explosion or fire, DO NOT USE AN OPEN FLAME TO CHECK FOR GAS LEAKS! Gas connections should be checked annually for leakage.

The tumbler 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 1/2 psig (3.45 kPa).

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 1/2 psig (3.45 kPa).
