Description
The HTP 91498 Blocked Vent Pressure Switch is a genuine OEM safety control designed to protect HTP boilers from hazardous blocked or restricted flue vent conditions. When the venting system becomes obstructed, this pressure switch detects the resulting change in pressure and shuts down the burner to prevent the buildup of harmful combustion gases — keeping your system, your building, and its occupants safe.
As a direct OEM replacement part, the HTP 91498 is engineered to exact factory specifications for seamless compatibility with the HTP boiler models it was designed to serve.
