6.0 CONDENSATE DRAIN
This unit produces liquid condensate in the heat exchanger and venting system as a product of combustion.
Steps must be taken to ensure condensate does not collect in the venting system; therefore, all exhaust piping
must slope back to the boiler a minimum 1/4" per linear foot of vent. Condensate must be drained from the unit
into a household drain.
Check with your municipality, or local gas company to determine if the disposal of
combustion condensate is permitted in your area (e.g. 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 drain
system (See Condensate Trap Installation Instructions for further details):
DO NOT install condensate lines outside. A frozen or blocked drain will cause the condensate to back-up
and leak. This may result in damage to boiler components resulting in a no heat condition; property damage
may also occur.
NEVER use copper, steel, or galvanized piping in the construction of the condensate system (condensate is
very corrosive and will corrode most metals).
When a condensate pump is used or required, select a pump that is designed for residential furnaces.
All tubing, drains and surfaces that come in contact with condensate draining from the
boiler, must be constructed out of corrosion resistant material; copper, steel and
galvanized are not acceptable materials for draining condensate. Failure to abide by this
caution will result in property damage.
Condensate Trap Installation Instructions (see Figure 6-1)
(Note: the Condensate Trap is factory supplied with the boiler and must be field installed)
1. Inspect Condensate Trap Assembly – Inspect the Condensate Trap to ensure all parts were shipped with
the assembly (see Figure 6-1). The Condensate Trap must be periodically disassembled and cleaned as part
of a regular maintenance plan.
2. Attach Corrugated Outlet Tube – Remove the Outlet Retaining Nut and Outlet Gasket and slide
components onto the Corrugated Outlet Tube – note orientation (gasket should be positioned
approximately 1/8" from the edge of the outlet tube – see Figure 6-1). Press the Corrugated Outlet Tube
into the Condensate Trap Outlet and firmly hand-tighten the Outlet Retaining Nut.
3. Attach to Boiler Condensate Drain (A) – Ensure the Ball-float is placed inside the condensate trap,
position the Inlet Gasket in between the condensate trap and boiler condensate outlet (See Figure 6-1).
4. Attach to Boiler Condensate Drain (B) – Secure the Condensate Trap into place by firmly hand-
tightening the Inlet Retaining Nut.
5. Outlet to Drain – Route the condensate from the Corrugated Outlet Tube to a household drain, condensate
pump or neutralizer (check with your local authority regarding the disposal of condensate), being careful
NOT to route it higher than the Condensate Trap outlet (see Figure 6-1).
The Condensate Trap must be periodically disassembled and cleaned as part of a regular
maintenance plan. Failure to clean the trap regularly can cause condensate drain blockage
leading to boiler malfunction, property damage and even personal injury.
Carefully follow the above instructions and the accompanying figure – check to ensure
the condensate trap is secure to the bottom of the boiler and that no strain is placed on it.
Failure to install the condensate trap properly will result in flue gas spillage and leeching
of carbon monoxide emissions into the surroundings resulting in serious injury or death.
