Installing T he Tandoor
PRESSURE REGULATING
The Tandoor and its individual shut-off valve must be disconnected from the gas supply piping system during
any pressure testing of that system at pressures in excess of 1/2 psig.
The Tandoor 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 at pressures equal or less than 1/2 psig.
Tandoor must have a pressure regulator on the incoming service line for safe and efficient operations.
Regulators installed must be listed by a nationally recognized testing agency. Line service pressure may fluctuate with
local demand. If the incoming pressure is in excess of 1/2 psig. A step down regulator will be required.
Minimum
incoming pressure must be 7” W.C. for natural and 11” W.C. for propane.
Manifold pressure should be checked with a manometer. Natural gas units require 6” W.C. and propane units
require 1o” W.C. Double check the arrow forged into the bottom of the regulator body which shows gas flow direction.
It should point downstream towards the appliance. The air vent cap is also part of the regulator and should not be
removed. The pressure regulator installed must be listed by a nationally recognized testing agency. If the vent line from
the gas appliance regulator is used, it should be installed to the outdoors in accordance with local codes or in the
absence of local codes, with the National Fuel Gas Code, ANSI z223.1-1988.
Regulators can be adjusted in the field, but it is not recommended that they be tampered with unless the part is
known to be out of adjustment or serious pressure fluctuations are found to exist and can be solved no other way. Any
adjustment to regulators must be made by qualified service personnel with the proper test equipment.
RATING PLATE
The Tandoor can be connected to either natural or propane gas, depending on the customers ordering instruc-
tions. Be sure the unit gas type matches the supply gas type. Gas type will be located on the rating plate.
The rating plate is attached to the inside of the lower front panel. Information on this plate includes the model
and serial numbers. This data is essential for proper identification when communicating with the factory about a unit or
requesting special parts or information. Other information on this plate is the BTU/HR input of the burners, outlet gas
pressure in inches W.C., and whether the unit is orificed for natural or propane gas.
The Tandoor can be connected to either natural or propane gas, depending on the customers ordering. Be sure
the unit gas type matches the supply gas type. The Tandoor is field convertible between natural and propane gas.
Contact customer service at (888) 281-5698 for conversion kit and conversion instructions.
Caution:
All connections must be sealed with a joint compound suitable for L.P. gas, and all connec-
tions must be tested with a soapy solution before lighting any pilots. DO
NOT use an open flame to
check for leaks. Putting an open flame beside a new connection is not only dangerous, but will often
miss small leaks that a soapy solution would find.
FLEXIBLE COUPLING, CONNECTORS, & CASTERS
If the unit is to be installed with flexible coupling and / or quick disconnect fittings, the installer must use a
heavy duty, commercial flexible connector at least 3/4” NPT (with suitable strain relief) in compliance with the standard
for connectors for movable gas appliances, ANSI Z21.69-1987 and Addenda, Z2.169a-1989 (or latest edition) or connec-
tors for movable appliances, CAN/CGA-6.16 (or latest edition) and a quick disconnect device must comply with the stan-
dard for quick disconnect devices for use with gas fuel, ANSI Z21.41-1989 (or latest edition) or quick disconnect devices
for use with gas fuel, CAN1-6.9 (or latest edition).
