VFC 15-150 - VFC 45-225 MODULATING GAS BOILERS
Do not place any water connections overhead the boiler; leaks can damage
the fan & controls. If needed, create a shield over the louvered top of the cover,
butallowclearanceforairowandserviceaccess.
For best results, use a Primary: Secondary piping system, with a pumped
boiler loop using 1-1/4" piping for the 15-150 and 1 1/2” for the 45-225. Heat
exchanger head for both models is approx. 7' at 14 gpm, and 12’ at 22 gpm
so an inexpensive fractional horsepower pump is normally adequate. Primary/
Secondarypipingensuresadequateowandde-couplesΔ°Tissues(boilervs.
distribution).Aimfora20°to30°FΔ°Tacrosstheheatexchangerathighre
(thereisaboilerprotectionthrottlefencelimitingtheΔ°Tto35°F).
WARNING
Close ll valve after any
addition of water to the
system, to reduce risk of
water escapement.
