Common Contractor Questions

Is the Robertshaw 700-434 compatible with LP gas?
This model is factory-set for natural gas. While some 700 series Uni-Kits include a regulator cover plate for conversion, always verify the specific orifice and regulator requirements before field converting to liquid propane.

What are the electrical requirements for this valve?
The valve operates on a standard 24V AC (0.2 Amps) or 12V DC (0.18 Amps) control circuit using combination screw/spade terminals for easy wiring.

Can I install this valve in any orientation?
Yes, the multi-positional design allows the valve to be mounted in any orientation except upside down. Always ensure the gas flow matches the arrow indicator on the valve body.
