USING GRILL WITH ON-BOARD CNG (NATURAL GAS) SYSTEMS
Magma's grills are designed for use with small disposable propane canisters or with pre-regulated
low-pressure propane and optional low-pressure valves. Running high-pressure propane fuel supply
lines on a boat is in violation of American Boat & Yacht Council (ABYC) guidelines and is not
considered a safe application. Additionally, impurities found in larger refillable propane tanks may
clog the small orifices in the high-pressure control valve/ regulator causing it to lose performance
capabilities and eventually fail. Regulating these tanks to 1/2 PSI and using this pre-regulated
propane with the correct low-pressure valve will insure safe, efficient performance of the grill.
Problem
Possible Cause
Electrode covered with grease or residue
Igniter/electrode too far from burner
Electrode wire loose,
disconnected, or corroded
Wire is shorted causing spark from wire
before electrode
No spark being generated
No gas flow
Obstructed gas flow
Excessive cooking temperature
Grease and/or residue build-up
Excessive fat in meats
Excessive oils in marinades
Obstructed gas flow
Flame too low
Wind directly on burner
Obstructed gas flow
Grill not level
Grease or residue build-up
Excessive fat in meats
Excessive oil in marinades
Possible Solution
Clean electrode
Adjust electrode until proper spark
appears (see page 5)
Clean, adjust & reconnect wire between
igniter & electrode, see Complete
Disassembly (page 5)

• Magma on-board CNG (natural gas) valves allow Magma grills to be installed to an existing on-board,
pre-regulated low pressure CNG (natural gas) system.
• Use only Magma Type 4 Low Pressure CNG (natural gas) control valves. Visit out website at
