Pentair Air Blower Kit 250K Natural Gas

The Pentair 460743 is the combustion air blower kit for the MasterTemp 250K BTU natural gas heater. It is the genuine Pentair part for the burner system.

What the blower does

A MasterTemp is a forced draft heater: the blower pushes air into the burner, and the control will not open the gas valve until it sees that air moving. A blower that has seized, slowed or lost its bearings is a heater that will not light, or one that shuts down partway through a cycle.

Match it to your heater

This kit is for the 250K model on natural gas. The 200K natural gas heater uses a different blower kit, so check the size and fuel on the rating plate before ordering. The photos show the blower from several angles so you can compare the housing, outlet and connector with the one coming off.
