2. Tubing Size: The connection at the rear of the heat
exchanger is designed for connection to 3/4" ID PVC
or similar tubing. Do not reduce the size of the
condensate drain tubing.
3. Tubing Pitch: Be sure that the pipe or tubing is pitched
away from the boiler with a slope of no less than 1/4"
per foot.
4. Multiple Boilers: Condensate drain tubes from
multiple boilers should be run separately to prevent a
nuisance lockout of multiple boilers due to a single
clogged drain tube.
5. Condensate Pumps: If the boiler drain is above the
level of a gravity drain, a condensate pump should be
used. Table 6.1 lists several available brands. Contact
your PB Heat, LLC Distributor for availability.
