Part number 550-141-850/0699

Vent starter tee — not included with boiler. See information below.

The vent starter tee is NOT supplied with the boiler. Obtain this part as a separate purchase from your Weil-McLain wholesaler.

The vent starter tee shown is for Saf-T Vent®. Use only the vent tee made for the vent system you are using. DO NOT mix different brands of vent system components. The vent system could fail to operate properly, causing leakage of flue products into the living space, resulting in severe personal injury or death.
