5.0 CONDENSATE DRAIN
This unit produces water as a product of combustion. Much of this water condenses on the heat exchanger and in the venting
system. All exhaust piping must be on a slope back to the boiler ¼” per linear foot of vent. Steps must be taken to ensure that
condensate does not collect in the venting system. Condensate must be drained from the boiler into a household drain.
Failure to properly connect the condensate trap and drain will cause combustion gases to enter the room
resulting in property damage, serious injury or death.
Note: check with your municipality, or local gas company to determine if disposal of combustion condensate is permitted.
In the State of Massachusetts the condensate must be neutralized prior to entering a drain.
The following are important notes that must be taken into consideration when constructing the condensate system:
DO NOT
run condensate line outside. A frozen or blocked drain will cause the condensate to fill the combustion
chamber. This will result in a no heat condition, as the unit will shut down, and damage to the flame sensor, and
components can occur.
NEVER
use copper, steel, or galvanized piping in the construction of the condensate system (condensate is very
corrosive and will rot most metals).
When a condensate pump is used or required, select a pump that is designed for residential furnaces.
If the condensate drain becomes blocked resulting in condensate backing-up into the heat exchanger, the
combustion chamber must be inspected and cleaned and internal refractory must be replaced; see
“Combustion Chamber Cleaning” in Section 17.0 for further details. Failure to follow these instructions will result in dangerous
boiler operation resulting in property damage, fire or loss of life.
The condensate drain kit supplied with each boiler is susceptible to flooding if the drain hose exiting the
kit is lengthened or inserted into a drain. If additional length is required, do not use the drain kit
provided, instead fabricate a 15” trap using tubing suitable for condensate disposal.
