Gas Pressure Regulator
The gas pressure regulator (which accompanies the product) is of utmost importance for its
operation and is indispensable. The pressure regulator must be installed in the product supply gas
line (failure to install the pressure regulator will void the equipment warranty).
Regulators are supplied with 3/4” NPT connection ranges. The regulator is factory set by 102mmH2O
(4” WC) water column gas pressure at connector (natural gas) and gas pressure at 254mmH2O (10”
WC) connector for LPG gas operation.
Before connecting the regulator, check the supply line pressure in the product. This may not exceed
the maximum pressure of 3.45kPa (1/2 PSI). If the gas supply line pressure is higher than indicated,
use a pressure reducing regulator.
At the bottom of the regulator body there is a gas direction arrow to minimize installation error. This
arrow should point to the device’s direction of entry into the product.
The blue air vent cap on the top of the regulator is part of the regulator and should not be removed.

IMPORTANT
Visually check all inlet pipes supplied by the installer and/ or blow them out using
compressed air to clean out any dirt or debris (threads or other foreign matter) before
installing a service line. These particles will clog the gas holes when gas pressure is
applied. Compounds used in appliance pipe threaded joints shall be resistant to the
action of GN and LPG gas and shall provide a gas tight seal to prevent leakage.
When installing the pressure regulator remember that it can support 1/2 PSI (3.45kPa).
When installing LPG, you have high source pressures ranging from 20 PSI (127.89kPa)
to 100 PSI (689.48 kPa). If the LPG tank’s high pressure gas line is directly connected
to a unit without the proper reduction regulator, it will rupture the diaphragm in the
valve, making it useless.
Any adjustment to the regulator should be done only by qualified and licensed
personnel with the appropriate calibrated test equipment.
Connections must be made my a licensed and qualified contractor.
