Where to mount tiger loop on boiler?

Baldiesrt Member Posts: 1
I need to move the tiger loop from my furnace to my boiler but I am afraid of screwing it onto the wrong place for the boiler. Can you please advise where I should screw it onto without damaging the inside and how high?

    Do you still have 2 appliances? Assuming you actually need a tiger loop & considering it's already not installed properly, just screw it in about the same place you had it on the furnace. With the short screws.

    Has anyone else tried this? Sorry I don't have a real photo, but all those customers are in NJ and I have retired to SC. BUT I have done this dozens of times on many furnaces and boilers. use a 1/4" x 3" nipple to affix the tiger loop directly to the fuel pump. Then you only need one flex hose to connect the outlet of the TL to the return port of the fuel pump.
