Gas Requirements

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 5

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 18.

Sediment traps

Shut-off valves

Supply pressure taps

It is important that equal pressure be maintained at all

tumbler gas connections. This can be done by

installing a 1 inch (25.4 mm) pipe gas loop to maintain

equal pressure at all gas connections. Refer to

Figure 19.

NATURAL GAS line pressure must be maintained at

6.5 water 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.).

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.

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.
