Electrical & Gas Requirements
LP/Propane Conversion
The DGVU cooktops are shipped natural gas,
and manufactured for use with natural gas or
LP/Propane gas. Check the rating plate located
on the bottom of the burner box for type of
gas needed.
• To convert to natural gas or LP/Propane gas,
the orifice spuds must be physically changed
and the regulator must be reset. Gas
conversions must be completed by a qualified
service technician.
• The installer must use a flexible connector of at
least ½" I.D. (1.3 cm) NPT and comply with
ANSI Z21.41 and Z21.69 standards.
WARNING
Conversion must be performed by a
qualified installer, service agency, or the
gas supplier in accordance with the
manufacturer's instructions. Failure to
follow instructions could result in serious
injury or property damage.
WARNING
Electrical power and gas must be turned
off prior to conversion.
To convert from both natural to LP/Propane and
LP/Propane to natural a conversion kit is
supplied.
Initial Ignition of Burners
• All cooktops are tested before leaving the
factory. Field adjustments may be necessary for
proper mixture of gas and air for proper
operation. Contact a qualified technician to
make any necessary adjustments.
• The surface burners use electric igniters in
place of standing pilots.

Proper Lighting and Shutdown Instructions
To ignite electric igniters on the surface burners:
1. Turn the knob counterclockwise to any
position.
2. Upon ignition of the surface burner, turn the

In case of failure, shut the gas OFF using the
installer supplied manual shut-off valve.
Low Flame Adjustment
DANGER
Lighting gas burners with a match is
dangerous. You should match light the
cooktop burners only in an emergency.
Light a match and hold the flame near the
burner you want to light. Wooden matches
work best. Push in and turn the control
knob slowly. Be sure you are turning the
correct knob for the burner you are lighting.
Note: If the burner does not light within five
seconds, turn the knob off and wait one
minute before trying again.
WARNING
If you attempt to measure the inner cone of
the flame, please use caution.
Burns could result.
This appliance is shipped from the factory with
low and medium flame settings adjusted.

Low Flame Adjustment (cont.)
If further adjustment is necessary, proceed as
follows:
Adjustment for Burners
1. Light burner and set control knob for low
flame.
2. Remove control knob from valve stem.
3. Using a flathead screwdriver, adjust the
screw to set flame size:
• clockwise to reduce
• counterclockwise to increase
4. Replace control knob when adjustment is
completed.

Low flame adjustment
Proper adjustment will produce a stable,
steady blue flame of minimum size. The final
adjustment should be checked by turning
knob from high to low several times without
extinguishing the flame.

This adjustment, at low setting, will
automatically provide the proper flame size
at medium setting. After conversion steps
have been completed, check the appearance
of each burner's flame at the HI and LO
settings. If the flames appear too large or too
small, review each step to make sure it was
completed correctly.
Burner Flames
Turn each burner on. Flames should be blue
in color with no trace of yellow. The burner
flames should not flutter or blow away from
the burner. The inner cone of the flame
should be between 1/2" and 3/4" long.
