Description

Raypak 004306F is the genuine electronic combination gas valve for propane, used on the Raypak 055A, 055B and 105A IID pool heaters.

What a combination valve is

Rather than separate components, a combination valve puts the safety shutoff, the pressure regulator and the main gas control into a single body. The heater control board energizes it during the ignition sequence, the valve opens, and gas reaches the burner at regulated pressure. That is the whole gas path in one part.

Propane only

This is the LP version. Propane and natural gas run at different pressures and take different valves, so the fuel your heater is set up for decides which part number you order. Do not substitute across fuel types.

When it is the failed part

The typical symptom is a heater that goes through its ignition sequence normally, sparks, and then locks out because the burner never lights. Once gas supply and inlet pressure to the heater check out, the combination valve is the next thing to test.
