Kit - TLV


The TLV helps prevent the furnace temperature from dropping below a specified temperature by bypassing the heat load and rerouting water back to the furnace.

The TLV is installed inside the heated building to allow heated water to continue to flow through underground pipes and prevent freezing.

(Note that the TLV Kit is a mandatory for all GX Series Furnace installations to maintain warranty coverage.)

This kit includes the fittings and all components necessary for installation (listed below). 

The Thermostatic Load Valve ("TLV") is a required component of all GX Series furnace installations, and is recommended for ALL outdoor boiler installations. Its purpose is to ensure that the outdoor boiler water jacket temp never falls below 140 degrees. Contact OutdoorBoiler.com for TLV installation instructions.
