CONVERSION
•
Instructions are for conversion from Natural Gas to Propane (L.P.) on all models HMG.
•
The conversion should be done before connecting the unit to the gas supply.
•
Units are shipped from the factory equipped for use on natural gas. Orifices necessary for LP (propane) are
provided in a bag tied to the valve on the front panel.
1. Remove the knobs and front panel.
2. Remove the orifice fittings from the valve. Change the orifices to the size recommended for propane
(L.P.).
3. Replace the orifice fittings into the valve.
•
To change the regulator:
•
Connect the regulator to the unit, connect gas and check for leaks. WARNING: Do not use an open flame
to check for leaks.
•
Check the system pressure. With the front panel removed remove the plug
from the manifold.
•
Place a fitting in the plug opening and connect a manometer.
•
For Natural gas the pressure in the manifold should be 5" water column or
12.4 millibar. For LP the pressure in the manifold should be 10" water Column of
24.9 millibar.
•
To adjust the pressure remove the brass cap and turn the white plastic part inside the stem of the regulator.
See picture regulator 8.
•
Take a wide straight screw driver and place it in the two notches shown in picture regulator 7 turn clockwise
to increase pressure and counter-clockwise to reduce pressure. See picture regulator 8.
•
Once the pressure has been adjusted replace the brass cap.
•
Note the blue cap on the regulator, this is the vent there are openings below the top rim. NEVER block
these openings your regulator will fail to operate correctly. On a monthly basis blow off any dust or grease
