Rugged Construction: Utilizing stainless steel bellows ensures resistance to vibration and long-term fatigue in high-pressure environments up to 245 psig MWP
Enhanced Safety: Maintains the specific airflow requirements necessary for proper pressure switch operation
this SPST (Single Pole Single Throw) switch ensures the combustion blower is moving sufficient air to safely vent flue gases before the ignition sequence initiates
which allows acidic water to bypass the seal and drip onto the furnace floor or inducer
