VR8245 and VR8345 Universal

Electronic Ignition Gas Controls

APPLICATION

The universal electronic ignition gas controls are used in

gas-fired appliances with capacities up to 415 cu ft/hour

at 1 inch wc pressure drop [11.8 cu m/hour at 0.25 kPa]

for natural gas. These gas controls will operate with a

direct spark (DSI), hot surface (HSI) or intermittent pilot

ignition. The control includes a manual valve, two

automatic operators, a pressure regulator, pilot

adjustment, pilot plug, conduit cover and ignition adapter.

Refer to the following list for the specifications.

SPECIFICATIONS

Ambient Temperature Range: -40° to 175°F

[-40° to 79°C].

Body Pattern: Straight-through.

Ignition Adapter: Configures device to operate with

direct spark or hot surface ignition.

Electrical Ratings:

Voltage and Frequency: 24 Vac, 50/60 Hz.

Current Draw: See Table 3 for current draw.

Capacity: See Table 1.

Capacity based on 1000 Btu/cu ft, 0.64 specific gravity natural gas at 1 in. wc pressure drop [37.3 MJ/cu m, 0.64 spe-

cific gravity natural gas at 0.25 kPa pressure drop].

Use conversion factors in Table 2 to convert capacities

for other gases.

Approvals:

American Gas Association Design Certificate:

L2025007.

Canadian Gas Association Design Certificate:

L2025007.

Pipe Adapters: Includes two 3/4 to 1/2 inch NPT bush-

ings and one 1/2 to 3/8 inch NPT bushing.

Models include: Natural to LP conversion kit and

Reducer bushings

Cross Reference: See Table 4 for cross reference infor-

mation.

VR8245 AND VR8345 UNIVERSAL ELECTRONIC IGNITION GAS CONTROLS MAINTENANCE CAUTION Do not apply a jumper across or short the valve coil terminals. Doing so can burn out the heat anticipator in the thermostat or damage the ignition module. WARNING FIRE OR EXPLOSION HAZARD CAN CAUSE PROPERTY DAMAGE, SEVERE INJURY, OR DEATH Improper cleaning or reassembly can cause gas leakage. When cleaning, be sure that the control is reassembled properly and perform gas leak test.
