INSTALLATION AND SAFETY GUIDELINES
GAS CONNECTION
The gas supply (service) line must be at least the same size or larger than the inlet line of the appliance.
THERMA-TEK restaurant series equipment is supplied with a ¾” NPT Schedule 40 inlet. Sealant on all
pipe joints must be resistive to LP gas.
MANUAL SHUTOFF VALVE
A manual shut-off valve must be installed in the gas service line ahead of the appliance and regulator in the
gas stream and in a position where it can be reached quickly in the event of an emergency. The manual shut-
off valve is supplied by the installer.
PRESSURE REGULATOR
All commercial cooking equipment must have a pressure regulator on the incoming service line for safe and
efficient operation, since pressure may fluctuate on local demand. A regulator is supplied with the
appliance.
Failure to install a pressure regulator will void the equipment warranty.
The regulators are
adjusted at the factory, 5.0” WC for natural gas, and 10.0” WC for propane gas. Ensure the supply pressure
is within the following range: Natural Gas 6.0” WC to 13.0” WC / Propane Gas 11.0”WC to 13.0” WC.
Only qualified service personnel with proper test equipment must make any adjustments to the regulators.
RIGID CONNECTIONS
Double check any installers supplied gas pipes visually and blow them out with compressed air to clear any
dirt particles, threading chips, or any other foreign matter before installing a service line. Those particles
will clog orifices when gas pressure is applied. All connections must be sealed with a joint compound for
LP gas, and tested with a soapy water solution before lighting any pilots.
FLEXIBLE COUPLINGS, CONNECTORS AND 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 ¾” 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 connectors for movable appliances, CAN/CGA-6.16 (or latest edition) and quick
disconnect device must comply with the standard 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, CAN1-69 (or latest
edition). Adequate means must be provided to limit the movement of the appliance. Domestic connectors
are not suitable.
When the appliance is supplied with casters and is connected to the supply piping by means of a connector
for movable appliances, and if disconnecting the restraint is necessary, this restraint must be reconnected
after the appliance is returned to its original installation position. The strain relief is a cable attached to the
rear of the appliance.
