V8200

Combination Gas Controls

APPLICATION

The V8200 Continuous Pilot Combination Gas Controls are 

used in gas-fired, standing pilot appliances. The include a 
manual gas valve, safety shutoff, single automatic operator 

and a pressure regulator.

FEATURES

• Add ECO switch where codes call for dual safety 

shutoff.

• For use with 24 Vac heating appliances that burn 

natural or liquefied petroleum (LP) gas.

• Capacity rated at 130 feet

3

/hour at 1 inch wc pressure 

drop (3.7m

3

/hr at 0.25 kPa). Maximum regulated 

capacity is 200 feet

3

/hour (5.7 meter

3

/hour). Minimum 

regulated capacity is 20 feet

3

/hour (.6 meter

3

/hour).

• Diaphragm-operated automatic valve opens under 

control of the regulator and closes if gas or power 

supply is interrupted.

• Three-position manual gas control knob has ON, OFF, 

and PILOT positions.Separate reset button must be 

held down to permit gas flow while lighting pilot; can 

be pushed down only in PILOT positions. All 
adjustments, wiring connections and pilot outlet are 

accessible from the top of the gas control.

• Compact size.
• Straight-through body pattern right angle adapters 

available for inlet and outlet.

• 1/2 inch inlet and 1/2 inch outlet; adapters available 

for 3/8 or 3/4 inch inlet or outlet.

• Adjustable servo regulator effectively maintains 

almost constant gas output pressure under wide 
fluctuations in gas supply pressure. Factory setting 

does not need readjustment for specific rating of 

furnace.

• Inlet and outlet screens included.
• Pilot filter included.
• Wiring terminal block color-coded beige to identify 

standing pilot models.

• May be installed at any angle between 0 and 90 degrees 

from the upright position, including vertically.

• 1/4 inch quick-connect terminals for electrical 

connections.

• 0°F to 175°F (-18°C to +79°C) temperature range 

standard; -40°F to +175°F (-40°C to +79°C) available.

• Inlet and outlet pressure taps included; both taps 

accessible from top of gas control.

• Standard, slow, and step-opening models available.
• ECO connector included with some models:  also 

available as accessory.

• Natural to LP gas conversion kit included with 

standard and slow-opening models.

• LP to natural gas conversion kit available for standard 

and slow-opening models.
