Gas Conversion - Viking VGR30 Service Manual

NATURAL GAS TO LP/PROPANE CONVERSION INSTRUCTIONS
This product is manufactured and adjusted for operation with natural gas as shipped from the factory. To operate with
LP/Propane gas, the following adjustments must be made.
!
A pressure regulator is located in the left rear corner of the burner box. To gain access to the pressure regulator,
remove the two left grates, two burner bowls, and the left grate support. Convert the regulator by removeng the
cap marked "NAT" and reverse it to read "LP". Be sure not to disturb or remove the spring beneath the cap.
!
To convert surface, griddle, grill, bake, and tubular burners to LP/Propane, turn the burner orifice hoods
clockwise until they become snug against the internal LP/Propane pin orifice, (See Illustration #2). After
adjusting the oven burner orifice hoods (Illustration #3, Item "3") for LP gas, it may be necessary to shift
the burner from position "4" to position "5" (Illustration #3) on the burner mounting bracket. This will
properly position the orifice hood in the burner venturi.
!
The orifice spud for INFRARED broilers has to be physically changed. Remove the #47 orifice spud and
replace with the #56 orifice spud (see Illustration #2) that is attached to the infrared broil burner gas supply
tubing. Attach the natural gas #47 orifice spud to the gas supply tubing for future use should the product need
to be reconverted to natural gas. Note: Changing the infrared fixed (spud) orifice must be completed
before the range is placed into the space provided.
