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
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).
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.
