The regulators supplied with MARKET FORGE INDUSTRIES, INC. Ovens, have 3/4” inlet /outlet openings
and are adjusted at the factory for 5” WC (
Natural gas
) or 10” WC (
Propane gas
) depending on
customer’s ordering instructions.
Prior to connecting the regulator, check the incoming line pressure, as these regulators can only
withstand a maximum pressure of ½ PSI (
14”WC
). If the line pressure is beyond this limit, a step-down
regulator will be required. The arrow shown on the bottom of the regulator body shows gas flow
direction; it should point downstream to the appliance. The red air vent cap on the top regulator is part
of the regulator and should not be removed.
Any adjustments to regulators must be made only by qualified service personnel with the proper
equipment.
Connections:
Please check installer-supplied intake pipes visually and /or blow them out with compressed air to clear
any dirt particles, threading chips, or other foreign matter before installing a service line. When gas
pressure is applied these particles can clog orifices. All connections must be sealed with a joint
compound suitable for LP gas, and all connections must be tested with a soapy water solution before
lighting any pilots!
Flexible Coupling, Connectors and Casters:
If the unit is to be installed with flexible couplings and /or quick-disconnect fittings, the installer must
use a AGA design-certified commercial flexible connector of at least 3/4” NPT (
with suitable strain relief
).
The flexible connector must comply with the standard for Connectors for Movable Gas Appliances, ANSI
Z21.69 and addendum Z21.69a (
or latest edition
) and a quick-disconnect device that complies with the
standard for quick-disconnect devices for use with Gas Fuel should comply with ANSI Z21.41 and
addendum Z21.41a (
or latest edition
). If disconnection of the restraint is necessary, make sure to
reconnect restraint after the appliance has been returned to its originally installed position. Domestic
gas or water connectors are not suitable!*Restraining device may be attached to the back frame/panel
of unit.
If the unit is to be installed with casters, a flexible connector must be used and the same ANSI standards
apply. Locking front casters are provided to limit the movement of the appliance without depending on
the connector or associated piping. A suitable strain relief must be installed with the flexible connector.
All connections must be sealed with a joint compound suitable for LP gas and all connections must be
tested with a soapy water solution before lighting pilots.
Lighting:
CAUTION:
When lighting pilots and checking for leaks, do not Stand with your face close to the
combustion chamber.
All MARKET FORGE INDUSTRIES, INC. appliances are adjusted and tested before leaving the factory,
effectively matching them to sea level conditions. Adjustments and calibrations to assure proper
operation may be necessary on installation to meet local conditions; low gas characteristics, to correct
possible problems caused by rough handling or vibration during shipment, and are to be performed only
by qualified service personnel. These adjustments are the responsibility of the customer and/or dealer
and are not covered by our warranty. Check all gas connections for leaks with a soapy water solution
before lighting any pilots.
