3.7 Gas Conversion Procedures
DANGER
This appliance was configured at the factory for a specific type of gas. Converting
from one gas type to another requires the installation of specific gas-conversion
components.
Switching to a different type of gas without installing the proper conversion
components may result in fire or explosion. NEVER ATTACH THIS APPLIANCE TO A
GAS SUPPLY FOR WHICH IT IS NOT CONFIGURED!
Conversion of this appliance from one type of gas to another should only be
performed by qualified, licensed, and authorized installation or service personnel, as
defined in Section 1.5 of this manual.
See page 3-12 for gas valve illustration and gas valve, burner and orifice location when performing
the following conversions.
When converting from G20 to G25 gas, the following procedures apply:
♦ Equipment replacement is not required.
♦ Adjust orifice gas pressure to the appropriate value listed in the table on page 3-9 – 3-10 by
turning the gas valve "adjustment screw".
♦ After adjustment, replace the adjustment-screw cover.
When converting from G20 (or G25) gas to G31 propane (or vice-versa), the following procedures
apply:
♦ Burner orifices and pilot orifice MUST be replaced.
♦ Adjust orifice gas pressure to the appropriate value listed in the table on page 3-9 – 3-10 by
turning the gas-valve adjustment screw.
♦ After adjustment, replace the adjustment-screw cover.
♦ Affix the new label included with the conversion kit next to the existing rating plate stating
that the gas type has been converted. Remove any references to the previously used gas
from the existing rating plate.
When converting from G20 (20 mbar) to G25 (25 mbar), or vice-versa, or G31 (37 mbar) to G31 (50
mbar), the following procedures apply:
♦ Check pilot-adjustment and adjust as necessary.
♦ Other adjustments are not necessary.
Conversion from one gas family to another (i.e. changing from natural gas to propane) requires
special components. Obtain the necessary components using the cross-reference in Section 3.8, Gas
Conversion Components.
