How to Select the Right Heater Conversion Kit Find the model # of your Modine heater and choose the option from the Heater Model # dropdown menu above that STARTS WITH the same letters and numbers. Note: These conversion kits are universal which means it does not matter if your heater has extra letters/numbers after the model # shown in menu above. Locate the model # on the heater's gas valve. Select the Gas Valve Model # option that STARTS WITH the same numbers or letters as the valve on your heater. If you are not sure which gas valve is on the heater, select the "SEND ALL KITS" option to receive all conversion spring kits for that heater. If you are replacing the gas valve and do not need a spring kit, select the "NONE" option. Common gas valve types are pictured below. NOTICE: Gas valves shown below are not included with conversion kits and are not needed to convert your Modine heater unless the valve on the heater does not match any of the model numbers in the options list above.
Honeywell Gas Valves Model # starts with V		Robertshaw Gas Valves Model # starts with 7		White-Rodgers Gas Valve Model # starts with 3
